Information Retrieval and Graph Analysis Approaches for Book Recommendation

الملخص EN

A combination of multiple information retrieval approaches is proposed for the purpose of book recommendation.

In this paper, book recommendation is based on complex user's query.

We used different theoretical retrieval models: probabilistic as InL2 (Divergence from Randomness model) and language model and tested their interpolated combination.

Graph analysis algorithms such as PageRank have been successful in Web environments.

We consider the application of this algorithm in a new retrieval approach to related document network comprised of social links.

We called Directed Graph of Documents (DGD) a network constructed with documents and social information provided from each one of them.

Specifically, this work tackles the problem of book recommendation in the context of INEX (Initiative for the Evaluation of XML retrieval) Social Book Search track.

A series of reranking experiments demonstrate that combining retrieval models yields significant improvements in terms of standard ranked retrieval metrics.

These results extend the applicability of link analysis algorithms to different environments.
