Identifying redundant search engines in a very large scale metasearch engine context

Proceedings of the 8th annual ACM international workshop on Web information and data management, 2006
For a given set of search engines, a search engine is redundant if its searchable contents can be found from other search engines in this set. In this paper, we propose a method to identify redundant search engines in a very large-scale metasearch engine context. The general problem is equivalent to an NP hard problem -- the set-covering problem.

Rank aggregation algorithm using particle swarm optimization for metasearch engines

The 10th IEEE International Symposium on Signal Processing and Information Technology, 2010
Rank aggregation is the algorithm that generates a consensus ranking from a given set of rankings from different sources. Rank aggregation algorithm has been found in many applications in web including metasearch and spam fighting. The proposed rank aggregation algorithm is called footrule optimal aggregation (FOA) because it is based upon optimizing ...

Concept Similarity and Cosine Similarity Result Merging Approaches in Metasearch Engine

, 2012
Metasearch engines provide a uniform query interface for Internet users to search for information. Depending on users need, they select relevant sources and map user queries into the target search engines, subsequently merging the results. In this paper, we have proposed a metasearch engine, which have two unique steps (1) searching through surface and

KhojYantra: an integrated MetaSearch engine with classification, clustering and ranking

Proceedings 2000 International Database Engineering and Applications Symposium (Cat. No.PR00789), 2002
Conventional search engines generally return a long ordered list of results which the users are forced to sift for getting relevant documents. It is envisaged that the search results can be greatly improved by integrating techniques, like ranking, classification and clustering.

Using online relevance feedback to build effective personalized metasearch engine

Proceedings of the Second International Conference on Web Information Systems Engineering, 2005
Metasearch Engine is popular for facilitating users' queries over multiple search engines and increasing the coverage of the WWW. How to rank the merged results becomes crucial for the success of metasearch engines. Many current metasearch engines have poor precision, for one or more of selected source search engine returns irrelevant results.

Automatic performance evaluation of web search engines using judgments of metasearch engines

Online Information Review, 2011
PurposeThe purpose of this paper is to introduce two new automatic methods for evaluating the performance of search engines. The reported study uses the methods to experimentally investigate which search engine among three popular search engines (Ask.com, Bing and Google) gives the best performance.Design/methodology/approachThe study assesses the ...

Search engines, metasearch engines and subject directories

2002
On WWW we can retrieve documents, view images and animation, listen to sound files... Programming language called HTML is in every Web document. Also, every Web document has a unique URL (uniform resource locator). Actually, it is the address of the web page. For access on the Internet we use a computer program called browser.
