An Approach for Building a Dictionary of Verb-Object Relations used in Methods

Software developers often use identifiers to link program elements with domain knowledge. If identifiers in a program have inappropriate name, developers consume much time to comprehend the program. This paper proposes a method to extract and gather verb-object (V-O) relations from source code written in object-oriented programming language.

Evaluation result confirms that the relations in the dictionaries are adequate. 1. は じ め に
