AI knowledge base guide

Last updated April 4, 2024

According to the Zendesk Customer Experience Trends Report 2024, 75 percent of customer experience (CX) leaders see artificial intelligence (AI) as a force for amplifying human intelligence, not replacing it. Not to mention, adding AI to your knowledge management systems can provide instant answers and AI-powered assistance at your fingertips.

Businesses strive to meet and exceed evolving customer expectations. With the right AI knowledge base, you’ll have the tools to surface relevant, accurate information, generate content, and supercharge your agents’ skill sets. Our guide to AI knowledge bases details how they work, how to build one, and the top software examples that can benefit your business.

What is an AI knowledge base?

An AI knowledge base is a centralized hub that leverages AI and machine learning (ML) to understand, process, and surface accurate and relevant information to users on demand. The system organizes, stores, and manages data and information. AI knowledge bases can help streamline customer support, enhance user experiences, and enhance decision-making.

How do AI knowledge bases work?

AI knowledge bases work like traditional knowledge bases but are enhanced with superpowers. A knowledge base relies on manual efforts to create, update, and organize content. It also requires predefined categories and keyword searches to retrieve information. AI knowledge bases harness the power of natural language processing (NLP) and ML technologies to automate content and knowledge management. Here’s how.

Natural language processing and machine learning in AI knowledge bases

Natural language processing (NLP) is a branch of AI that enables computers to understand, interpret, and generate human language. NLP algorithms analyze and comprehend the meaning and context behind text or speech input.

Machine learning (ML) algorithms learn from data inputs, improve performance, and make predictions or decisions without explicit programming. They identify patterns, refine search results, and analyze data for personalized responses based on user interactions.

How they work together: ML algorithms analyze and learn from the data input (user queries, interactions, and feedback) to continuously improve the knowledge base's performance. They refine search results, enhance understanding of user queries, and recommend more accurate and contextually relevant information over time.

When users interact with an AI knowledge base, the system learns from their interactions, refines its understanding of language nuances, and adapts to provide more accurate and helpful responses in the future.

The benefits of an AI-powered knowledge base

An AI-powered knowledge base is more than just an automated system. It offers a wealth of benefits that help customers, agents, and business operations. Here are just a few.

A bulleted list highlights the benefits of AI-powered knowledge base software.

Enables customer self-service

AI-powered knowledge bases empower customers to find solutions independently. Customer self-service is enabled through intuitive search capabilities and AI-driven recommendations. Users can swiftly access relevant information, FAQs, troubleshooting guides, and tutorials. Self-service enhances customer satisfaction by providing immediate, 24/7 support.

Streamlines content and content creation

AI algorithms can assist with content management by identifying content gaps, detecting outdated resources, and suggesting new topics based on customer feedback and ticket requests. For example, AI can detect a spike in specific customer requests, such as asking for help with password resets over live chat. AI can flag content management teams and recommend creating knowledge base articles on this topic.

Accelerates agent onboarding and training

AI-powered knowledge base systems can help streamline new agent onboarding and training by offering comprehensive, up-to-date resources. A centralized hub allows agents to quickly find and access training guides, documents, and important customer information, leading to faster issue resolution. Additionally, AI algorithms can suggest relevant materials to support agents, recommend articles within tickets, and help with writing content.

Reduces operational costs

AI-driven knowledge bases significantly reduce operational expenses. For instance, self-service capabilities can decrease the number of support tickets, minimizing the need for extensive support teams. Plus, the system's ability to handle more inquiries helps control operational costs and boosts overall agent efficiency.

Ensures a consistent customer experience

AI-powered knowledge bases can help deliver a cohesive tone and precise content across all help center articles. This helps make sure that the information shared with customers across various touchpoints is consistent and accurate. Consistency builds customer trust, strengthens brand reputation, and fosters positive customer experiences, leading to higher retention rates and brand loyalty.

Types of AI-powered knowledge base content

AI-powered knowledge bases are a comprehensive repository of information made up of several different kinds of content. All of this information allows businesses to efficiently manage, access, and leverage diverse forms of data to enhance customer support, decision-making, and overall operational effectiveness.

Structured knowledge content

Structured knowledge content refers to information that gets organized and formatted systematically. This content typically includes articles, FAQs, manuals, and guides. It’s usually arranged into a strategic hierarchy where the most relevant or useful information is at the top. Creating structured knowledge content with standardized formats, consistent terminology, and optimized keywords or categories allows for efficient knowledge base searches.

Unstructured knowledge content

Unstructured knowledge content encompasses information that lacks a specific format or predefined structure. This type of content includes:

  • Customer emails
  • Chat transcripts
  • Social media interactions
  • Forum discussions
  • Multimedia files (like audio recordings or images)

Unstructured content is more challenging to organize and analyze due to its varied formats and lack of standardized structure. However, AI-powered systems use NLP and ML algorithms to extract insights and meaning from unstructured data, making it accessible and valuable within the knowledge base.

Automated knowledge content

Automated knowledge content refers to information generated or curated automatically by AI algorithms. This content gets continuously updated, refined, or created based on user interactions, feedback, and data analysis.

For instance, AI algorithms might automatically generate suggested responses to common customer queries, create summaries of lengthy documents, or offer recommendations for improving existing content based on user engagement metrics. Automated content assists in streamlining content creation, ensuring relevance, and enhancing the knowledge base's accuracy and efficiency.
