Abstract : |
Developments in text retrieval on the AP1000 since last year's PCW are reported. The software, now called PADRE, has been entered in the competition associated with the 1994 Text Retrieval Conference (TREC-3). PADRE is now capable of document relevance estimation and ranking, and supports data loading from and dumping to the Fujitsu Local Filesystem. A new load balancing operation has been devised and implemented and improved techniques for handling cell-program error conditions have been adopted. Experiments have been successfully carried out on document collections exceeding 1.5 million documents and 5 gigabytes of data. Performance results are presented. 1, |
