I am not sure if: (a) Ontologies and semantic web will provide one more metric to a search engine such as google, for checking the relevance of any webpage against a query. (or) (b) Ontologies and semantic web will fundamentally change the paradigm for information retrieval, and the results from this will far outweigh the current paradigms such as -- page rank, word importance in document, closeness of words, and other google proprietary techniques.. I would like to mention if anyone thought of the relevance of IBM's CLEVER project.. They used the link structure of the web to find communities on the web.. basically the idea was: for every community, there exists some directories which keeps track of main pages in this community. Their idea was to find say 3 directories which all point to say all of 3 pages or so.. Once they do that, they have identified the core of a community. Then this core can be expanded to include "relevant" but "non-core" pages, and similarly other relevant directories.. Once this is done, we have identified an entire community.. Once a community is found, one can find some keywords/semantics related to this community by extracting some common keywords etc.. The whole thing was done automatically.. Semantic web is an improvement over this, how much more of an improvement.. will people hard-code ontologies (or) because of the expressiveness of RDF, for example, to specify how multiple communities are related, we can get better results even though everything is still automatic..?? I was just thinking aloud.. best regards, murali.
