Web searching and Σ2 queries
Sharma, Arun (2004) Web searching and Σ2 queries. In Yu, Jeffrey Xu, Lin, Xuemin, Lu , Hongjun, & Zhang, Yanchun (Eds.) Advanced Web Technologies and Applications : proceedings of the 6th Asia-Pacific Web Conference, Springer-Verlag , Hangzhou, China, pp. 20-23.
In the terminology of Logic programming, current search engines answer Sigma1 queries (formulas of the form where is a boolean combination of attributes). Such a query is determined by a particular sequence of keywords input by a user. In order to give more control to users, search engines will have to tackle more expressive queries, namely, Sigma2 queries (formulas of the form ). The purpose of the talk is to examine which directions could be explored in order to move towards more expressive languages, more powerful search engines, and the benefits that users should expect.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
