Throughout this chapter, we have taken our first look at the Knowledge APIs. We started by linking entities using the Entity Linking API. Doing so allows us to recognize entities based on context and link all entities of the same type in a text. Moving on, we dived into the Recommendations API. We learned how to set up recommendation models using existing catalog and usage data. Using these models, we learned how to utilize these in a simple example application.

In the next chapter, we will continue with Knowledge APIs. We will learn how to structure natural language queries and evaluate query expressions. In addition, we will learn how to add auto-completion to natural language queries.
