Abstract

Metadata is a resource which can assist the information retrieval of digital documents on the Internet. In designing a metadata system, it is necessary to consider the characteristics of digital documents, such as the variety of file formats, frequent format transformation and the difficulty of distinguishing between the different versions. Provides a brief analysis of some existing metadata formats, and introduces several pronciples for the future development of cataloguing on the Internet. Briefly describes the Metadata Experimental System (MES) currently under development, and located at the author's homepage

Abstract

One of the major causes of search failures in information retrieval systems is vocabulary mismatch. Presents a solution to the vocabulary problem through 2 strategies known as term suggestion (TS) and term relevance feedback (TRF). In TS, collection specific terms are extracted from the text collection. These terms and their frequencies constitute the keyword database for suggesting terms in response to users' queries. One effect of this term suggestion is that it functions as a dynamic directory if the query is a general term that contains broad meaning. In term relevance feedback, terms extracted from the top ranked documents retrieved from the previous query are shown to users for relevance feedback. In the experiment, interactive TS provides very high precision rates while achieving similar recall rates as n-gram matching. Local TRF achieves improvement in both precision and recall rate in a full text news database and degrades slightly in recall rate in bibliographic databases due to the very limited source of information for feedback. In terms of Rijsbergen's combined measure of recall and precision, both TS and TRF achieve better performance than n-gram matching, which implies that the greater improvement in precision rate compensates the slight degradation in recall rate for TS and TRF
