One major problem in semantics-based component retrieval process is the discrepancy between nature language which users are familiar with and formal semantic descriptions of components

which makes users difficult to describe retrieve queries precisely.An interactive query generation method is proposed to solve this problem.The method uses concept identification process to map users’ nature language to ontology descriptions of components

in which concept identification uses conversational process to interact with users.This method extracts implicit semantics in user queries so that it leads to improve recall and precision rates

reduce query effort in component retrieval.
