Abstract: Software component (SC) technology is regarded as the new hope to upgrade productivity of SC, shorten date of delivery, and raise quality of the software. The management, retrieval, orientation, and comprehension of the reusable SC are important factors in the reuse. Being the research focus, people are trying, for many years, in different ways and with various devices expressing and retrieving reusable SC, thus, more and newer reusable technologies are appearing with the development in the research. This article introduces the present situation in expressions and methods of retrieval of components, and gives some appraisals for their future progress.
