The World Wide Web contains a huge quantity of text that is notoriously inefficient to use. This work aims to apply a text processing technique based on thesaurally derived lexical chains to improve Internet Information Retrieval where a lexical chain a set of words in a text that are related by both proximity, and by relations derived from an external lexical knowledge source such as WordNet, ...

A fully operational large scale digital library is likely to be based on a distributed architecture and because of this it is likely that a number of independent search engines may be used to index different overlapping portions of the entire contents of the library. In any case, different media, text, audio, image, etc., will be indexed for retrieval by different search engines so techniques w...

We have explored how redundancy based techniques can be used in improving factoid question answering, definitional questions (“other”), and robust retrieval. For the factoids, we explored the meta approach: we submit the questions to the several open domain question answering systems available on the Web and applied our redundancy-based triangulation algorithm to analyze their outputs in order ...

The longevity of printed guides to resources on the web is a topic of some concern to all librarians. This paper attempts to determine whether guides created by specialist librarians perform better than randomly assembled lists of resources (assembled solely for the purpose of web studies), commercially created guides (‘Best of the web’-type publications), and guides prepared by specialists in ...
