Using semantic, geographical, and temporal relationships to enhance search and retrieval in digitalwhich often return unsatisfactory search results. Against this background, digital catalog systems are becoming more and more popular. Unlike earlier search engines, they contain information about information (meta-information) available on the Internet or in the holdings of digital libraries but no

Relevance feedback and query expansion for searching the web: A model for searching a digital libraindependent search engines may be used to index different overlapping portions of the entire contents of the library. In any case, different media, text, audio, image, etc., will be indexed for retrieval by different search engines so techniques which provide a coherent and unified search over a sui

Text segmentation by topic,ication in full-text databases. Researchers have tackled similar problems before but with different goals. This study focuses on data with relatively small segment sizes and for which within-segment sentences have relatively few words in common making the problem challenging. We present a method for

Scalable text retrieval for large digital libraries, be required to operate over collections of this magnitude. Algorithms expected to be capable of scaling to these data sizes using clusters of modern workstations are described. First, basic indexing and retrieval algorithms operating at performance levels comparable to other leading systems over gi

Awareness services for digital libraries, interact with clients that perform indexing, replication, intellectual property management, revenue management, and other functions. One of the most critical components in such stores is the awareness mechanism, used to notify clients of inserted, deleted or changed objects. In this paper we survey

Towards a common infrastructure for large-scale distributed applications, to support them. A design for an infrastructure that aims at satisfying these requirements is presented. Moreover, it is shown how key aspects of important large-scale applications can exploit the services included in the proposed infrastructure. The paper concludes by discussing the current status

Machine learning + on-line libraries = IDL, information capture, which involves complex pattern recognition problems, and integration of different DBMS technologies, in order to connect many libraries to form a unique virtual library. This paper presents IDL, a prototypical intelligent digital library service. IDL addresses both the problems

Automated indexing with thesaurus descriptors: A co-occurrence based approach to multilingual retripensive. Automated indexing methods in general use terms found in the document. Thesaurus descriptors are complex terms that are often not used in documents or have specific meanings within the thesaurus; therefore most weighting schemes of automated indexing methods are not suited to select thesaur
