When Documents Deceive: Trust and Provenance as New Factors for Information Retrieval in a Tangled Web.
Peer reviewed Peer reviewed
Lynch, Clifford A. – Journal of the American Society for Information Science and Technology, 2001
Outlines a view of the changing framework for information retrieval suggested by the Web environment. Speculates about how some of these changes may manifest in upcoming generations of information retrieval systems. Sketches ideas about the broader context of trust management infrastructure that will be needed to support these developments, and…

Chinese Document Indexing Based on a New Partitioned Signature File: Model and Evaluation.
Peer reviewed Peer reviewed
Lam, Wai; Wong, Kam-Fai; Wong, Chi-Yin – Journal of the American Society for Information Science and Technology, 2001
Investigates the use of signature files in Chinese information retrieval systems and proposes a new partitioning method-called Partitioned Signature File for Chinese (PSFC)-based on the characteristics of Chinese words. Experimental results confirm the features of PSFC and demonstrate its superiority over the traditional single signature file…

Employing the Resolution Power of Search Keys.
Peer reviewed Peer reviewed
Pirkola, Ari; Jarvelin, Kalervo – Journal of the American Society for Information Science and Technology, 2001
The resolution power of a key is its ability, in the context of other keys for a given request, to increase query performance. This article studies the statistical properties of search keys, methods of characterizing the resolution power of keys automatically, and effects keys of varying resolution power have on retrieval effectiveness.
