Knowledge AI Best Practices: Ensure Accuracy & Relevance

Company knowledge is only useful when employees can find the right information and trust what they receive. Knowledge AI best practices focus on making AI-powered knowledge search accurate, relevant, current, secure, and easy to use.

Building reliable Knowledge AI requires trusted knowledge sources, strong retrieval quality, contextual answers, appropriate access controls, AI Guardrails, human oversight for exceptions, and continuous evaluation of search performance.

Accuracy matters because adoption depends heavily on trust. Deloitte research on trust in workplace AI found that employees are 2.6 times more likely to use AI consistently when trust is present. For Knowledge AI, reliable answers are therefore more than a technical requirement. They influence whether employees trust AI-powered knowledge search enough to keep using it.

When these practices work together, Knowledge AI can turn scattered company information into reliable employee self-service across HR, IT, and other workplace needs. Workativ takes this approach further by connecting trusted knowledge with AI-powered employee support and the actions employees may need to complete after finding an answer.

For teams also comparing different approaches to workplace knowledge search, this guide to the best Glean alternativesexplores platforms that combine enterprise search, Knowledge AI, AI agents, and automation.

This guide covers practical ways to improve Knowledge AI accuracy, search quality, relevance, governance, and adoption.

The quality of Knowledge AI depends on the quality of the information it can retrieve and the context in which that information is used.

A response can be factually correct and still be unhelpful if it is outdated, irrelevant to the employee's situation, or based on information they should not be able to access. This is why effective AI-powered knowledge management needs to consider more than whether an answer simply sounds correct.

Four factors have a direct impact on the quality of Knowledge AI answers.

• Accuracy starts with trusted knowledge

Knowledge AI should retrieve information from authoritative and approved sources. If multiple versions of a policy, procedure, or support document exist, the AI needs a reliable source of truth.

For example, an employee asking about parental leave should receive information from the approved policy rather than an older document that is still stored somewhere in the company's knowledge base.

Accuracy therefore starts before an AI-generated answer is created. It depends on the quality of the knowledge available for retrieval.

• Relevance depends on the employee's context

An accurate answer is not necessarily the right answer for every employee.

Knowledge AI should consider the context surrounding a request, such as the employee's role, department, location, application, permissions, and the intent behind the question.

For example, an employee asking about leave should receive the policy that applies to their location and employment type rather than every leave policy available across the organization.

This ability to retrieve information based on context is an important part of effective AI-powered knowledge search.

• Freshness keeps answers aligned with current information

Company knowledge changes continuously. HR policies are revised, benefits change, applications are updated, and IT procedures evolve.

Knowledge AI should prioritize current information and prevent outdated content from influencing answers. If an employee asks how to configure a VPN, for example, the system should retrieve the latest setup procedure rather than instructions for an application the organization no longer uses.

Regular knowledge maintenance, version control, and synchronization with connected knowledge sources can help keep answers aligned with current information.

• Authorization determines what Knowledge AI can reveal

Finding the correct information does not automatically mean it should be returned to every user.

Knowledge AI should respect identity, role, and source-level permissions when retrieving information. An employee may be allowed to access a general HR policy while confidential employee records, restricted IT documentation, or sensitive business information remain protected.

This is where AI Guardrails become important. Guardrails can help organizations protect sensitive information and establish boundaries around how AI behaves and responds.

Accuracy, relevance, freshness, and authorization therefore need to work together. Accurate information without relevance can still produce a poor answer. Relevant information that is outdated can mislead the employee. And accurate, relevant, current information should still not be returned when the user is not authorized to access it.

This is why improving Knowledge AI involves more than adding documents to a knowledge base. The quality of the content, retrieval, context, and access controls all influence whether employees receive an answer they can actually use.

The next factor is search quality. If Knowledge AI repeatedly retrieves the wrong information, even a capable AI model will struggle to produce answers employees trust and continue using.

How does search quality affect adoption?

Search quality directly affects whether people continue using Knowledge AI. Even when the underlying company knowledge is accurate, poor retrieval can surface the wrong document, miss important context, or fail to find the information an employee needs.

Why does search quality matter in Knowledge AI? It is because the quality of the information retrieved directly affects the quality of the answer the AI can generate.

That creates a clear relationship between search quality and adoption:

• Better search quality improves answer quality. Knowledge AI has a stronger foundation for generating useful answers when it retrieves the right information for the user's question.

• Reliable answers build trust. Employees are more likely to rely on Knowledge AI when answers are consistently accurate, relevant, and supported by trusted company knowledge.

• Trust encourages repeat usage. When employees get useful answers without repeatedly searching, rephrasing questions, or contacting HR or IT, they have a reason to return.

• Repeat usage drives adoption. Knowledge AI becomes part of everyday AI-powered employee self-service when people see it as a dependable way to find information.

The opposite is also true. If employees repeatedly receive irrelevant, incomplete, or outdated answers, they may stop using Knowledge AI and return to manual search, HR or IT tickets, or direct requests to support teams.

Improving adoption therefore starts with more than making AI available. It requires making the knowledge retrieval behind every answer reliable.

See how enterprise search software helps organizations improve knowledge discovery and make information easier for employees to find across company systems.

How to ensure accuracy is one of the most important questions when implementing Knowledge AI. Reliable answers depend on more than the AI model itself. They depend on the quality of the knowledge retrieved, how well that knowledge matches the user's question, and what the system does when reliable information is unavailable.

The following Knowledge AI best practices help reduce incorrect answers and improve the reliability of AI-powered knowledge search.

Start with authoritative knowledge sources

Knowledge AI should have a clear understanding of which sources can be trusted.

Instead of treating every document, webpage, knowledge article, and file as equally authoritative, identify the sources that should take priority for different types of questions. These might include approved HR policies, IT knowledge articles, benefits documentation, operating procedures, or content maintained in systems such as SharePoint, Confluence, Google Drive, and other knowledge repositories. Clear ownership matters too. Important knowledge should have an owner responsible for reviewing and updating it when policies, processes, or systems change. The stronger the underlying knowledge, the stronger the foundation for accurate AI answers.

Remove duplicate, outdated, and conflicting information

Connecting more content does not automatically make Knowledge AI more accurate. Duplicate documents, old policy versions, conflicting instructions, and abandoned knowledge articles can make it harder for AI search to determine which information should be used.

Before making content available to Knowledge AI:

• Remove or archive outdated versions of important documents.

• Consolidate duplicate knowledge where possible.

• Identify conflicting information and establish which source is authoritative.

• Add ownership and review dates to information that changes frequently.

• Retire content when the underlying policy, application, or process is no longer in use.

This also helps reduce one common source of AI hallucinations. When retrieved knowledge is incomplete, outdated, or contradictory, an AI system has a weaker factual foundation for generating its response.

Ground AI answers in enterprise knowledge

Knowledge AI should generate answers from relevant organizational knowledge rather than relying only on the general information learned by a large language model.

This is where retrieval-augmented generation (RAG) becomes useful. RAG retrieves relevant information from connected knowledge sources and provides that information to the language model as context for generating an answer. For example, an employee asking about parental leave should receive an answer grounded in the company's approved leave policy rather than a general explanation of parental leave found in an LLM's training knowledge. For a deeper explanation of the technology, see Workativ's guide to retrieval-augmented generation (RAG). RAG does not automatically guarantee accuracy. The quality of the answer still depends on the quality, relevance, and freshness of the information retrieved. That is why knowledge preparation and retrieval quality remain essential parts of Knowledge AI.

Use human-in-the-loop when judgment is required

Not every knowledge request should end with a fully automated answer.

Routine questions supported by clear, approved knowledge can often be handled directly by AI. Human involvement becomes more important when the request includes an exception, approval, sensitive decision, uncertainty, or business judgment.

For example:

• A routine question about the published PTO policy can be answered using approved HR knowledge.

• An employee asking for an exception to that policy may need HR involvement.

• An IT question about an approved troubleshooting procedure can be answered automatically.

• A request requiring privileged access or security approval may need an authorized person to make the decision.

This human-in-the-loop (HITL) approach allows AI to handle repeatable knowledge requests while people remain responsible for decisions that require judgment. For HR teams, this principle becomes particularly important when AI moves beyond answering questions and starts participating in workflows. Workativ's HR automation approach uses human-in-the-loop controls for steps that require HR or manager judgment while routine steps continue automatically.

Define when Knowledge AI should not answer

A reliable Knowledge AI system also needs to know when not to provide an answer.

If approved knowledge is missing, conflicting, insufficient, or inaccessible to the user, the system should not be designed to fill the gap with a confident-sounding response.

Instead, organizations should define fallback behavior such as:

• Tell the user when reliable information could not be found.

• Ask for clarification when the question does not provide enough context.

• Direct the user to an approved source when appropriate.

• Escalate the request to HR, IT, or another responsible team when human assistance is required.

• Prevent an answer when the user does not have permission to access the underlying information.

This is an important part of reducing hallucinations in Knowledge AI. The goal is not to make the AI answer every question. It is to help employees get a reliable answer when the necessary knowledge exists and provide a safe next step when it does not.

Accuracy therefore comes from the combination of trusted knowledge, clean content, grounded retrieval, human judgment, and well-defined fallback behavior.

How do you prepare enterprise knowledge for AI search?

Preparing enterprise knowledge for AI search is different from traditional data preprocessing for machine learning. The goal is not simply to give an AI system more data. It is to make sure the knowledge it retrieves is structured, current, trustworthy, and accessible to the right people.

Before connecting company knowledge to Knowledge AI, review the information employees actually depend on and address the issues that can weaken retrieval quality.

Structure knowledge so AI can retrieve the right context

Good content structure benefits both employees and AI search. Long documents with unclear headings, mixed topics, or important information buried in unrelated sections can make it harder to retrieve the most relevant context. Where possible, organize knowledge around clear topics and use descriptive headings that reflect the questions employees are likely to ask.

For example, a single benefits document containing enrollment rules, eligibility, deadlines, claims information, and contact details can be easier to retrieve accurately when those topics are clearly separated and labeled. This becomes particularly important when organizations connect knowledge from multiple systems. Workativ's guide to AI knowledge management explains how AI can help organizations make distributed workplace knowledge easier to access and use.

Use metadata and ownership to add context

Metadata can help distinguish information that looks similar but applies in different situations.

An HR policy, for example, may apply only to a particular country, employment type, or employee group. An IT procedure may apply to a specific application, operating system, device, or user role. Useful metadata can help Knowledge AI retrieve information with that context in mind. Ownership is equally important. Critical knowledge should have someone responsible for keeping it accurate, reviewing changes, and retiring outdated information.

Preserve permissions when connecting knowledge sources

Preparing knowledge for AI search should not mean making every connected source available to every employee. Knowledge AI should preserve appropriate access permissions and account for who is making the request. A document can be highly relevant to a query while still being inappropriate for that user to retrieve. This is especially important when AI search spans HR, IT, SharePoint, knowledge bases, and other repositories that may contain sensitive or restricted information.

The objective is therefore not to index everything. It is to make the right knowledge clean, structured, current, contextual, and appropriately accessible before Knowledge AI relies on it.

Improving relevance in Knowledge AI search means retrieving information that fits the user's actual question and situation, rather than simply finding content with similar words.

Two employees can ask the same question and need different answers because of their location, role, permissions, employment context, or the application they use. Relevant Knowledge AI search needs enough context to understand those differences.

Understand employee context

Knowledge AI should use available context to narrow down which information applies to the employee and their request.

Useful context can include:

• Role and department to distinguish information intended for different teams or responsibilities.

• Location when policies, benefits, support procedures, or regulations vary by country, state, or office.

• Employment context when HR information differs by employment type, eligibility, or other applicable employee conditions.

• Application or device when an IT question depends on the software, operating system, or equipment being used.

• Query intent to understand what the employee is actually trying to accomplish rather than relying only on keywords.

• Conversation context to understand follow-up questions without requiring the employee to repeat the entire request.

For example, if an employee asks, “How many vacation days do I get?”, the most relevant answer may depend on their location and employment type. If someone asks, “How do I connect to the VPN?”, the right instructions may depend on their device or operating system.

This is one reason large language models are changing enterprise knowledge search: semantic and contextual understanding can help knowledge search move beyond simple keyword matching.

Respect access permissions

Relevance alone should never determine what Knowledge AI retrieves.

A document may be highly relevant to an employee's question but still contain information they are not authorized to access. Knowledge AI should respect the permissions associated with the user and the connected knowledge source before information is used in an answer.

For example, an employee searching for compensation information might be allowed to access the company's published compensation policy, but that does not mean the same search should retrieve confidential salary records available only to HR.

The same principle applies to IT. General troubleshooting documentation may be available to everyone, while security procedures or privileged infrastructure information may require restricted access.

Relevant Knowledge AI search therefore means finding the best information the user is also authorized to receive.

Learn from employee queries and feedback

Relevance should improve based on what happens after Knowledge AI is deployed.

Direct employee feedback is useful, but it is only one signal. Search behavior can reveal where retrieval is failing even when an employee never submits a rating.

Teams should look for:

• Unanswered questions that reveal missing or inaccessible knowledge.

• Negative feedback that identifies answers employees found incorrect, irrelevant, or incomplete.

• Rephrased queries that suggest the first search failed to understand the employee's intent.

• Repeated searches that indicate the employee did not get what they needed the first time.

• Escalations to HR or IT that reveal questions Knowledge AI could not resolve reliably.

These signals can help teams identify knowledge gaps, improve content, and refine how information is retrieved.

For a broader look at applying Knowledge AI to workplace questions, see how Knowledge AI can automate employee queries.

The goal is not simply to return more search results. It is to make each answer more useful to the person asking the question while respecting the context and access controls that determine which information actually applies.

How do you keep Knowledge AI up to date?

Knowledge AI needs continuous maintenance because company information keeps changing. Policies are revised, benefits change, applications are updated, and old procedures become obsolete.

A few practices help keep AI-powered knowledge accurate and current.

Assign knowledge owners and review dates

Important knowledge should have a clear owner responsible for reviewing and updating it. Add review dates based on how frequently the information changes rather than treating every document the same.

For example, benefits enrollment information may require more frequent reviews than a relatively stable workplace policy.

Use version control and archive outdated content

When policies or procedures change, remove or archive superseded versions from active retrieval. Otherwise, Knowledge AI may encounter multiple versions of the same information and struggle to determine which one applies.

A well-maintained enterprise knowledge base should make current information easy to identify while keeping older versions from interfering with employee search.

Keep connected knowledge sources synchronized

Knowledge AI often retrieves information from multiple sources, including SharePoint, Google Drive, Confluence, websites, PDFs, and internal knowledge bases.

Updates in those systems should be reflected in the knowledge available to AI so employees are not given answers based on stale copies of source content.

Review knowledge when something changes

Do not rely only on scheduled reviews. Important business changes should trigger a knowledge review.

• Policy or regulatory changes should trigger a review of affected employee guidance.

• Benefits or payroll changes should trigger updates to related HR knowledge.

• Application changes should trigger reviews of IT troubleshooting and support documentation.

• Repeated failed searches should trigger investigation into missing, unclear, or outdated knowledge.

Keeping Knowledge AI current therefore comes down to clear ownership, regular reviews, version control, source synchronization, and fast updates when the underlying information changes.

Knowledge AI search quality should be measured by more than usage or the number of questions employees ask. A high volume of searches does not necessarily mean employees are finding useful answers.

Instead, measure whether Knowledge AI retrieves the right information, resolves the employee's question, and identifies where the underlying knowledge or search experience needs improvement.

Use search behavior to improve Knowledge AI

These metrics become more valuable when teams look at them together.

For example, repeated searches followed by an escalation may indicate poor retrieval or missing knowledge. A rise in negative feedback after a policy change could indicate that outdated content is still being retrieved.

This is where AI Agent analytics can help teams understand how employees interact with AI, identify unresolved requests, and find opportunities to improve the experience.

The goal is not to maximize the number of AI interactions. It is to increase the percentage of employee questions that Knowledge AI can answer accurately, relevantly, and reliably.

Knowledge AI can make company information easier to access, but that access still needs boundaries. Governance should define what knowledge AI can retrieve, who can access it, how sensitive information is handled, and what happens when a safe or reliable answer cannot be provided.

Key controls should include:

• Permissions that preserve appropriate access to HR, IT, and other restricted knowledge.

• Sensitive information controls that prevent confidential or personal information from being unnecessarily exposed.

• Source traceability so teams can understand which knowledge contributed to an answer.

• Auditability to provide visibility into AI interactions and important actions.

• Knowledge ownership so responsibility for maintaining critical information remains clear.

• Safe fallback when Knowledge AI cannot find sufficient approved information or should involve a person instead.

These controls become especially important when Knowledge AI supports HR and IT, where employee data, internal procedures, and restricted information can exist alongside general company knowledge.

Use AI Guardrails to control Knowledge AI behavior

Permissions control access to knowledge, while AI Guardrails add another layer of control around how AI should behave and respond.

Depending on the use case, guardrails can include:

• PII masking to reduce unnecessary exposure of personally identifiable information.

• Topic controls to define subjects the AI is allowed or not allowed to discuss.

• Output controls to establish boundaries around generated responses.

• Prompt-injection protection to help defend against attempts to manipulate AI instructions or access inappropriate information.

• Rate limiting to control excessive or abusive usage.

• Profanity filtering where organizations need additional controls around employee-facing conversations.

Workativ's AI Guardrails provide configurable controls for protecting AI interactions while organizations use AI Agents and Knowledge AI across employee support.

Guardrails should work alongside permissions, trusted knowledge, and human oversight rather than replacing them. Secure Knowledge AI depends on controlling both what information AI can access and how it is allowed to use that information.

What are the most common Knowledge AI mistakes?

Many Knowledge AI problems start with the knowledge and retrieval strategy rather than the AI model itself. Gartner notes that deploying AI search without preparing the underlying content can lead to poor-quality results, while IBM similarly points out that retrieving an outdated or incorrect source can still produce a wrong answer even when RAG is being used.

Avoid these common mistakes when building and improving Knowledge AI:

Indexing everything without preparing the content

Giving Knowledge AI access to more documents does not automatically improve search quality.

Before connecting a source, identify outdated, duplicated, poorly structured, and low-value content. Gartner's research on AI search and intranet content specifically emphasizes preparing underlying content before deploying AI-powered search.

Leaving outdated and conflicting knowledge active

Old policies, duplicate procedures, and conflicting instructions make it harder to retrieve a reliable source.

Define authoritative content, maintain versions, and remove superseded information from active retrieval instead of assuming the AI will always determine which document is correct.

Treating RAG as a guarantee of accuracy

RAG can ground an answer in company knowledge, but it cannot make incorrect knowledge correct.

If retrieval surfaces an outdated policy or irrelevant document, the generated answer can still be wrong. IBM describes this problem directly in its research on knowledge fragmentation and RAG.

Ignoring permissions because the content is relevant

Semantic relevance does not equal authorization.

Knowledge AI should preserve access controls when retrieving information from HR, IT, and other company repositories. Sensitive information should not become available simply because it closely matches someone's query.

Forcing Knowledge AI to answer every question

A reliable Knowledge AI experience should be able to say when it does not have enough approved information to answer safely.

When knowledge is missing, conflicting, restricted, or uncertain, use a safe fallback or involve the appropriate person instead of allowing the AI to fill the gap. This can reduce the risk of confident but unsupported answers.

Measuring usage instead of answer quality

High usage alone does not prove that Knowledge AI is working.

Measure retrieval relevance, unanswered questions, negative feedback, repeated searches, rephrased questions, and escalations alongside adoption. These signals show whether employees are actually getting useful answers.

Collecting feedback without improving the knowledge

Feedback only creates value when teams act on it.

Use unsuccessful searches, employee feedback, and recurring escalations to identify missing knowledge and improve retrieval. Workativ's Knowledge AI includes feedback and analytics capabilities designed to help teams understand and improve how users interact with company knowledge.

Treating trust as a launch problem instead of an ongoing requirement

Employee trust can decline quickly when AI repeatedly produces unreliable answers. Deloitte found that employees who trust AI are 2.6 times more likely to use it consistently, reinforcing why accuracy, transparency, and reliable knowledge matter beyond initial deployment.

Knowledge AI therefore needs continuous attention to content quality, retrieval, permissions, evaluation, and safe fallback rather than a one-time implementation.

How do Knowledge AI best practices apply to HR and IT?

The same Knowledge AI best practices apply across HR and IT, but the knowledge, context, permissions, and human decisions behind each use case are different.

An HR AI agent may need to understand an employee's location and eligibility before answering a benefits question. An IT AI agent may need to know the employee's device, application, or access level before providing troubleshooting guidance.

Knowledge AI provides the answer, while HITL and Guardrails add control

Knowledge AI can handle routine questions when trusted information is available and the employee has permission to access it. AI Guardrails help establish boundaries around what the AI can discuss or expose, while human-in-the-loopbrings the appropriate person into requests that require approval, judgment, or exception handling.

For example, an AI agent for HR can answer a published leave-policy question using approved HR knowledge, while an exception to that policy can be routed to HR or a manager.

Similarly, AI-powered IT support can help employees find troubleshooting information, while privileged access requests or security-sensitive exceptions remain with authorized IT teams.

The objective in both cases is the same: use Knowledge AI for reliable self-service while keeping sensitive information and human decisions appropriately controlled.

Knowledge AI best practices checklist

Before launching Knowledge AI, and as usage grows, teams need a consistent way to check whether the underlying knowledge, search experience, and controls are working as expected.

Here is a quick preview of what to review.

Before launching Knowledge AI

• Confirm that important answers come from authoritative and approved knowledge sources.

• Remove or resolve duplicate, outdated, and conflicting content.

• Verify that permissions and access controls are preserved across connected sources.

• Test Knowledge AI using real employee questions, including variations in wording, intent, and context. See these Knowledge AI use cases for employee queries for examples of how workplace questions can vary across HR and IT.

• Define when AI should answer, ask for clarification, or involve a human.

After launching Knowledge AI

• Review unanswered and repeatedly rephrased questions.

• Monitor retrieval and answer quality, not just usage.

• Identify knowledge gaps behind unsuccessful searches and escalations.

• Use employee feedback and search behavior to improve content and retrieval.

• Re-test important answers when policies, systems, or source content change.

The complete checklist covers the full Knowledge AI lifecycle, including knowledge readiness, search and retrieval, accuracy, permissions, testing, launch, measurement, governance, and continuous improvement.

How does Workativ help teams build more reliable Knowledge AI?

Workativ brings Knowledge AI together with AI Agents, actions, guardrails, human involvement, and analytics so employees can move from finding trusted information to resolving a request within the same experience.

Knowledge AI can be the starting point, not the stopping point

An employee may begin with a knowledge question but ultimately need something done.

Someone asking about software access may need an application provisioned. An employee asking about leave may want to submit a request. And a person who cannot resolve an IT issue from the available knowledge may need a support ticket created.

Workativ's AI Agent Studio brings knowledge, instructions, application integrations, actions, and human handoff into the AI Agent experience. This allows routine requests to continue beyond an answer while exceptions can still involve the appropriate person.

What this looks like in practice

GoTo provides a useful example. The company deployed Workativ for a workforce of 5,000 employees, across IT and HR, with more than 50 applications in its environment.

GoTo originally had knowledge fragmented across systems including SharePoint and its service-management environment. With Workativ, employees can use a single AI Agent in Slack for knowledge and employee-support requests, while the platform can also work across connected applications when an action is required.

Today, 84% of GoTo's employee requests are auto-resolved with AI, while employees can still escalate requests that require additional support.

The GoTo customer story shows how this combination of knowledge, AI-powered self-service, integrations, and automation works in a real employee-support environment.

That is the broader role of Knowledge AI within Workativ: make trusted company knowledge easier to find, use that knowledge within employee conversations, take action when appropriate, and bring people in when AI should not make the decision.

Effective Knowledge AI is not simply about connecting more documents to an LLM. It depends on trusted knowledge, relevant retrieval, appropriate access, AI Guardrails, human judgment when needed, and continuous measurement.

When those pieces work together, Knowledge AI becomes more than another way to search company information. It gives employees a reliable way to find what they need, understand what applies to them, and move forward without navigating multiple systems or waiting for routine support.

Workativ brings these capabilities together by combining Knowledge AI, AI Agents, Guardrails, human-in-the-loop, and application actions in one employee support experience. Teams can use their existing knowledge and business applications while keeping people involved where approval, exceptions, or judgment are required.
