Why We Use Dependency Parsing
For beginners, text analysis often begins with a simple keyword search. Analysts can start by searching for “great service”. They may then begin adding other searches like “service was great” or “service is so great”. This, of course, is a very rudimentary approach that will miss a lot of relevant comments, so users who want to get more results quickly will advance to proximity searches. For example, they may search for “great” within three words of “service”. While some may use word lists (“awesome”, “good”, or “excellent” service) or parts of speech (adjectives near “service”) to improve results, most text analysis systems stop right there. For advanced text searching, however, you need to have information about word relationships.
