Development of a semantic-based content mapping mechanism for information retrieval

Most information retrieval systems use keywords entered by the user as the search criteria to find documents. However, the language used in documents is often complicated and ambiguous, and thus the results obtained by using keywords are often inaccurate. To address this problem, this study developed a semantic-based content mapping mechanism for an information retrieval system. This approach employs the semantic features and ontological structure of the content as the basis for constructing a content map, thus simplifying the search process and improving the accuracy of the returned results.

► Develops a mechanism for preprocessing, abstraction, recognition, and annotation of the semantic features of content. ► Designs a content map to record and represent these features. ► Uses the content map to develop a semantic-based content mapping mechanism.
