摘要：At present, educational institutions have developed their library database systems, or used library package programs. Some educational institutions had many libraries such as the university libraries, the faculty libraries, and the department libraries. However, standards in developing and designing the library systems were differently applied. These differences caused the problems when sharing the link of data from many libraries. That was, it encountered the problem of centralized semantic query because each library stored the same data, but chose to use different vocabulary to describe the data. As there was no common agreement or standard for describing data, it brought about the semantic conflicts of synonyms and homonyms. In this paper, the ontology-based semantic integration of heterogeneous data sources by using the ontology mapping approach was implemented for solving such the problem. The results of the study revealed that the architecture of the semantic integration of heterogeneous data sources using the ontology mapping approach could effectively resolve the semantic conflicts of linking the library data from various sources. Based on the performance evaluation of the proposed architecture, it was found to be highly effective with Precision, Recall, and F-measure, at 90.34%, 91.98%, and 91.15%, respectively.
