Chapter 6. Mining Web Pages: Using Natural Language Processing to Understand Human Language, Summarize Blog Posts, and More
This chapter follows closely on the heels of the chapter before it and is a modest attempt to introduce natural language processing (NLP) and apply it to the vast source of human language1 data that you’ll encounter on the social web (or elsewhere). The previous chapter introduced some foundational techniques from information retrieval (IR) theory, which generally treats text as document-centric “bags of words” (unordered collections of words) that can be modeled and manipulated as vectors. Although these models often perform remarkably well in many circumstances, a recurring shortcoming is that they do not maximize cues from the immediate context that ground words in meaning.
This chapter employs different techniques that are more context-driven and delves deeper into the semantics of human language data. Social web APIs that return data conforming to a well-defined schema are essential, but the most basic currency of human communication is natural language data such as the words that you are reading on this page, Facebook posts, web pages linked into tweets, and so forth. Human language is by far the most ubiquitous kind of data available to us, and the future of data-driven innovation depends largely upon our ability to effectively harness machines to understand digital forms of human communication.
