Knowledge Base overview
Tiledesk offers a powerful hybrid (semantic + keyword search) RAG (Retrieval-Augmented Generation) module – the Knowledge Base – purpose-built to deliver accurate, context-aware responses based on your organization’s knowledge.
It is powered by a native RAG (Retrieval Augmented Generation) architecture, combining the capabilities of large language models with your company’s content to deliver relevant and contextual responses.
With a fully no-code management interface, you can add, update, and organize your knowledge sources directly in Tiledesk with zero-coding.
Technology
When an AI Assistant needs to answer a question, it uses Tiledesk’s hybrid fulltext-semantic search engine to find the most relevant information:
Fulltext search: finds exact matches of words and phrases in your documents.
Semantic search: understands the meaning behind the question, even if different words are used compared to the documents.
Hybrid mode: combines both approaches to return results that are both precise and semantically relevant. (For more details, see our Hybrid search & Tiledesk Hybrid Search RAG Architecture articles.)
The AI then generates an answer using this content, ensuring it is consistent with your company’s information and using by default the same language the user adopted for the question.
For more details see the How the Knowledge Base works article.
Create a new Knowledge Base
With Tiledesk you can create multiple Knowledge Bases in your project. This is useful in many cases:
If you need to create AI Assistants responding on different domains such as different products, different support departments (e.g. Support and Sales) etc.
If you want to create a Knowledge Base chain. For example, first ask the Website, on website fallback ask the official documentation pdfs and on fallback finally ask the self learning knowledge base.
Other scenarios that will come to mind in the future : )
You can create two kind of Knowledge Bases with different types of indexing/searching, all managed through the Tiledesk UI.
Select the 🧠icon on the sideleft menu, you will be redirected on the Default Knowledge Base that Tiledesk automatically creates for you on your projects. If you want a new one, you can press the New Knowledge Base button on the left.
Note: You can't delete the Default Knowledge Base neither change its type that only supports Semantic search (Standard, see later)
Chose the KB type
Before creating a new Knowledge base you must provide the name and choose your preferred type
Standard or Hybrid?
The main difference between the two is the followinig
Standard is powered by a classic Semantic Vector indexing. This means that the information retrieval is made using the semantic of the phrases and chunks, not specific keywords. It works very well in the majority of cases, but it doen't suite very well when you deal with uncommon words such as acronyms, alfanumeric codes, names etc.
Hybrid mixes results coming from a Semantic approach mixed with a full-text based one. To the final result is also applied a re-ranking alghoritm that improves the query results. This is a more powerful query engine that provides more flexibility, power and precision on your results.
Populate with your contents
Add a new source
Click + Add and choose the type of content to import:
URLs: enter the address of one or more web pages (one on each line) to index.
Sitemap: upload the URL of an XML sitemap to bulk import all its pages. It's very similar to the URLs importer, except that the first step extracts all the URLs contained in the sitemap you provided as a URL.
Questions & Answers: manually create Q&A cards for quick, specific replies. You can also bulk import your Q&As using a CSV file
PDF or DOCX documents: upload files containing guides, manuals, technical sheets, or other text content.
Configure your Knowledge Base
You can configure and test your Knowledge Base directly from the administration zone using the Configure toolbar buttons as in the following figure
When you press the Preview button a test popup will allow you to setup the user question and see how the Knowledge base reply based on your contents
You can provide your question in any language, the knowledge base will reply accordingly
As you can see you can inspect reply's info such as the delay and tokens consumption, and you can inspect the returned chunks and sources too.
You can experiment with AI configuration while in test mode. Click on the top right gear of the Preview popup and you will see the configuration window. Here you can play with all the options, from LLM model selection, to System context, etc.
Knowledge Base Settings
Pressing the gear in the Configure toolbar you can set the Knowledge base general configuration.
The configuration window has many options:
