Experimenting with HITS based Algorithms with new Heuristics for assigning the link weights

Maroun, Bashir M. (Notre Dame University-Louaize, 2001)

This thesis uses the link structure of the World Wide Web as a basis to create better search engines. It focuses on the HITS algorithm, which was the first algorithm to up the link topology. HITS is implemented with slight modifications and tested with variations of its input parameters. It is also used in order to discover emerging communities in cyberspace. Other related algorithms, which use the link structure of the web as an undirected graph are described and compared with HITS. Finally, an attempt to combine link-based with text-based analysis in order to create more accurate search methods ...
Toward an interactive internet search engine

Akl, Imad M. (Notre Dame University-Louaize, 2002-06)

This thesis uses the HITS algorithm as a basis to propose an interactive internet search engine. With the Web becoming a major source of information for many users, it became a necessity to be able to search the Web efficiently. The main problem resides with broad topic queries. These are queries for which a typical text-based search engine like AltaVista would return thousands of pages. A remedy for these situations was proposed by Kleinberg in his 1-IITS algorithm in which he uses the hyperlink structure of the Web as a major source of information about the contents of the Web. In this thesis, ...
