A GRAPH BASED APPROACH TO COMPARING SEARCH ENGINES
Jinghao Miao, Daniel Berleant · 2003
In the investigation of paragraph-linked hypertext repositories, the algorithms generating link networks have in-depth impacts on the phenomena of centrality or dispersion that are identified as important issues to be dealt with in the process of information foraging. Furthermore different repositories, generated through different search engines, even produced by the same algorithms, still shown significant variations with different degrees of centrality or dispersion. We have studied this using the MultiBrowser system as a testbed, and applying some algorithms to repositories consisting of documents downloaded based on five different search engine return lists. We study the hyperlinks added automatically to these repositories, which make these documents navigable from other documents within the repositories. The property of centrality and dispersions of linked repository can be further investigated. Keywords: MultiBrowser, search engines, direct display,
