Abstract (Summary)

With the proliferation of Web 2.0, social tag is widely used in various applications. Online bookstores (like Amazon) and online bibliographic community Websites (like LibraryThing) have quickly accumulated a large amount of user-generated information. INEX (INitiative for the Evaluation of XML retrieval) have been using the Amazon/LibraryThing corpus for its Social Book Search Track since 2011. The purpose of the INEX Social Book Search Track is to develop novel algorithms leveraging professional metadata and user-generated metadata for effectively retrieving books. This thesis uses INEX 2013 Social Book Search Track test data set to conduct book search experiments and evaluate the retrieval results. Indices based on professional metadata, user-generated metadata and both are created respectively.

The results of this study are summarized as follows: Using social data in the probabilistic retrieval model for Book Search outperforms using traditional bibliographic data. Using all book data including reviews in the probabilistic retrieval model for Book Search can get the best retrieval performance. Using social tag information in the probabilistic retrieval model for Book Search has no significant difference with traditional bibliographic data, but using the number of times a tag used as weight to retrieval can improve the retrieval performance. Using reviews data for re-ranking can achieve the best search results in this study; it can improve 3.1% of the nDCG scores. Using tag data for reranking can improve 25% of the nDCG score. Practically, the results of this thesis can be used as a clue for the design of a book search system and a book recommendations system.
