Expertiza is a web application that supports peer-review for a variety of entities. As it is still evolving, expertiza has several areas that require work. Among these include areas that require refactoring existing code to improve code quality. The graph_generator.rb file is one such area. This write-up describes our refactoring decisions for this file.

The first change that can be seen within this method is the extracting of code that adds on to a previous vertex or creates a new one, all based upon the part of speech defined of the tokens encountered while parsing the review. We called our extracted method tagged_token_check. BY extracting this method, we were able to reduce duplication (since such similar code occurred four times in the method for tokens that are nouns, adjectives, adverbs, and verbs. Since the code contained nested if statements, we also were able to reduce the complexity of the method. Screenshots of the code before and after refactoring are included below. The top picture is the code before refactoring, the middle is the code after, and the bottom is the code within the extracted method.
