descriptions, and specificity one of index terms. They are most clearly illustrated by a simple keyword or descriptor system. In this case the exhaustivity of a document description is the coverage of its various topics given by the terms assigned to it; and the specificity of an individual term is the level

by recording their reactions to documents they read. The reactions are called annotations; they can be accessed by other people’s filters. Tapestry is intended to handle any incoming stream of electronic documents and serves both as a mail filter and repository; its components are the indexer, document store

in the management literature, in fact little is known about the reasons why "enriched" work sometimes leads to positive outcomes for workers and for their employing organizations. Even less is known about the relative effectiveness of various strategies for carrying out the redesign of work One reason

Abstract—This paper provides a definition of the term “software engineering ” and a survey of the current state of the art and likely future trends in the field. The survey covers the technology available in the various phases of the software life cycle—requirements engineering, design, coding

Abstract. This paper first describes various strategies (character, bigram, automatic segmentation) used to index the Chinese (ZH), Japanese (JA) and Korean (KR) languages. Second, based on the NTCIR-5 testcollections, it evaluates various retrieval models, varying from classical vector

conceptions of 'subject ' in the literature are not explicit but implicit.

. They conclude that swap market-specific supply/demand shocks drive the unexplained changes in swap rates. Existing literature on credit spread changes is limited. 3 Pedrosa and Roll (1998) document considerable co-movement of credit spread changes among index portfolios of bonds from various industry, quality

Web spam pages use various techniques to achieve higher-than-deserved rankings in a search engine’s results. While human experts can identify spam, it is too expensive to manually evaluate a large number of pages. Instead, we propose techniques to semi-automatically separate reputable, good pages

The performance of various indexing techniques, namely, manual indexing, automatic indexing, and combined manual and automatic indexing in retrieving Indonesian news articles is evaluated. The result of using structured and Boolean queries show that the combined indexing technique is more effective

joint detection. This uses the orthogonal structure of the space–time block code and gives a maximum likelihood decoding algorithm which is based only on linear processing at the receiver. We review the encoding and decoding algorithms for various codes and provide simulation results demonstrating
