Research in user behavior on online catalogs is in its early stages, but preliminary findings suggest that users encounter many of the same problems identified in behavioral studies of other types of bibliographic retrieval systems. Much can be learned from comparing the results of user behavior studies on these two types of systems. Research on user problems with both the mechanical aspects an...

In this study we develop and propose publication metrics, based on an analysis of data from the Chandra bibliographic database, that are more meaningful and less sensitive to observatory-specific characteristics than the traditional metrics. They fall in three main categories: speed of publication; fraction of observing time published; and archival usage. Citation of results is a fourth categor...

Music information retrieval (MIR) as a nascent discipline is blessed with a multi-disciplinary group of people endeavoring to bring their respective knowledge-bases and research paradigms to bear on MIR problems. Communication difficulties across disciplinary boundaries, however, threaten to impede the maturation of MIR into a full-fledge discipline. The principal causes of the communications b...

I will consider the problem of helping user’s retrieve information from large diverse collections of textual materials such as bibliographic databases, electronic bulletin boards and online manuals, although I believe that many of my arguments apply to other interactive environments as well. Information retrieval systems like this must handle a heterogeneous population of users, and even a sing...

This paper explores the ability to define bibliographic classification systems as socially significant documents in a way that goes beyond their immediate function information retrieval process. It does so dialog with theory on and documentality, knowledge organization theory. Two examples show how development of new address social cultural structures periods rapid change crisis. The first exam...

This paper describes the results of the first step in the development of a comprehensive project aimed at realizing a portal and a set of advanced services supporting the sharing of knowledge about Prehistory and Protohistory in the Italian context. In particular, one of these services is represented by a digital library, whose entries (i.e. bibliographic descriptions of publications) will be o...

Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...

Advances in Computers The past 30 years have been a period of rapid development for computers and their uses. In computer hardware, we have seen a progression from vacuum tubes to transistors to integrated circuits to microprocessors. In computer uses, we have seen an expansion beyond military and business applications that includes computeraided design and manufacturing, bibliographic data ret...

With the rapid expansion of scientific research, the ability to effectively find or integrate new domain knowledge in the sciences is proving increasingly difficult. While development of information systems to promote scientific discovery is being explored on a number of fronts, much of this work is based on traditional search and retrieval approaches and the bibliographic citation format remai...
