Throughout this chapter, we have focused on the Language APIs. We started by creating the parts needed to execute API calls to the different services. Following this, we looked at the Bing Spell Check API. Next, we learned how to use web language models to break words and calculate probability of word sequences. We moved into more analytical APIs, where we learned how to detect languages, key phrases, and sentiment. We completed the chapter by taking a brief look into linguistic analysis.

The next chapter will take us from Language APIs into Knowledge APIs. In this chapter, we will learn how to recognize and identify entities based on context. In addition, we will learn how to use the Recommendations API.
