Classification Methods for Software Components based on Relationships between Software Components Abstract: In recent years, the size of software becomes more large scale. So the number of software components that compose one software is also increasing and the relationships between software components becomes more complicated. So we would like to assist software comprehension by presenting components that play similar roles, or components whose positions are almost the same. In this paper, we suggest two classification methods for software components based on relationships between software components. One is based on the similarity of several metrics based on the component graph, and the other is based on the similarity of using components (or components that are used by). We will show application examples of the two classification methods and discuss their characteristics. Keywords: Software Component, cluster analysis, use-relation, relation about code clone. 1. ͸͡Ίʹ. ͱͰશମΛ೺Ѳ͢Δ͜ͱ͕೉͘͠ͳΓɼ͞Βʹ෦඼ؒͷؔ ܎΋ෳࡶԽ͍ͯ͘͜͠ͱͰɼϓϩάϥϜͷ಺෦ߏ଄ͷཧղ. ۙ೥ͷιϑτ΢ΣΞ։ൃ‫ݱ‬৔Ͱ͸ɼ։ൃର৅Ͱ͋Διϑ. ͸ࠔ೉ͳ΋ͷͱͳΔɽେ‫ن‬໛͔ͭෳࡶʹͳͬͨιϑτ΢Σ. τ΢ΣΞͷେ‫ن‬໛ԽɼෳࡶԽ͕‫ʹܹٸ‬ਐߦ͍ͯ͠ΔɽͦΕ.
