Annotating wikipedia articles with semantic tags for structured retrieval
Saravadee Sae Tan, Tang Enya Kong, Gian Chand Sodhy · 2009
Structured retrieval aims at exploiting the structural information of documents when searching for documents. Structured retrieval makes use of both content and structure of documents to improve information retrieval. Therefore, the availability of semantic structure in the documents is an important factor for the success of structured retrieval. However, the majority of documents in the Web still lack semantically-rich structure. This motivates us to automatically identify the semantic information in web documents and explicitly annotate the information with semantic tags.
