Object-oriented code is considered to be inherently more reusable than functional decomposition code; however, object-oriented code can suffer from a program understanding standpoint since good object-oriented style seems to require a large number of small methods. Hence code for a particular task may be scattered widely. Thus good semantics based tools are necessary. This paper describes an approach to object-oriented code understanding that focuses largely on informal linguistic aspects of code, such as comments and identifiers.>
