Index structures for selective dissemination of information by T. W Yan( Book )

1 edition published in 1992 in English and held by 8 WorldCat member libraries worldwide

In this paper, we propose several index structures for standing orders and algorithms that efficiently match documents against large number [sic] of orders. We also present analysis and simulations results to compare their performance under different scenarios."
Index structures for information filtering under the vector space model by T. W Yan( Book )

3 editions published in 1993 in English and held by 6 WorldCat member libraries worldwide

We apply the idea of the standard inverted index to index user profiles. We devise an alternative to the standard inverted index, in which we, instead of indexing every term in a profile, select only the significant ones to index. We evaluate their performance and show that the indexing methods require orders of magnitude fewer I/Os to process a document than when no index is used. We also show that the proposed alternative performs better in terms of I/O and CPU processing time in many cases."
