Classifying and retrieving software components based on profiles

We propose that the software reuse system can classify, register, and retrieve software components based on their profiles. There are two profiles: object profiles are constructed by extracting from software components their identifiers, function identifiers, and variable identifiers. Virtual profiles are made by extracting common identifiers and their weights from object profiles or virtual profiles. By similarity function, the similarity values between profiles and software components are calculated, classified, registered by their value. To retrieve software components, keywords representing the software components and their weights are input by users. The similarity value of keywords and profiles is calculated, and software components with the highest similarity value are retrieved. This system can register and retrieve software components more easily than other system and classify and retrieve software components faster then the systems using conventional information retrieval methods.
