چکیده

We participated in Web retrieval tasks in order to investigate the integration of multiple retrieval results. We also examined the possibility of using a general retrieval system designed for organized documents, such as news articles that match users’ queries, to retrieve unorganized documents, such as Web documents. Our results show that if information retrieval systems use the OKAPI method, results can be used for Web retrieval that is based on scored results without score normalization. On the other hand, if the systems use Rocchio’s feedback method, ranked results are shown to be the best.

Merging Strategy Based on Logistic Regression

With the development of network technology, the users looking for information may send a request to various selected databases and then inspect multiple result lists. To overcome such multiple inspections, the database merging strategy involves the merging of the retrieval results produced by separate, autonomous servers into an effective, single ranked list.

Algorithm for Layered Sorting and Merging of P2P Information Retrieval

Due to the intrinsic characteristics, P2P information retrieval has faced quite a few challenges, and it is one of the urgent problems how to sort and merge the retrieval results from multiple nodes. For this reason, we propose a novel algorithm for layered sorting and merging of P2P information retrieval. In the proposed approach, the query submitting node submits the query string to the nodes...
