BACKGROUND Comprehensive health technology assessments (HTAs) include thorough reflections on ethical issues associated with health technologies, their use, and value-based decisions in the assessment process. As methods of information retrieval for effectiveness assessments are not applicable to information retrieval on ethical issues, a specific methodological approach is necessary. OBJECTI...

extension of information together with the need for its use in a suitable and appropriate time is one of the important goals in this century – the information century. the user query that is accessibility to the requested text information in a short time must be satisfied using effective techniques. this is performable under text compression and retrieval, which have been treated separately bef...

Question Answering (QA) is an emerging important field in Information Retrieval. In a QA system the archive of previous questions asked from the system makes a collection full of useful factual nuggets. This paper makes an initial attempt to investigate the reuse of facts contained in the archive of previous questions to help and gain performance in answering future related factoid questions. I...

Relatively little research has been published about bibliographic visualization, although scientists, researchers, and students often have need for such technology. In this paper, we examine the functionality needed to visualize bibliographies e ectively. After reviewing some existing tools, we present BIVTECI (Bibliographic Visualization Tool with Enhanced Citation Interactivity) which derives...

User studies focusing upon real-life music information needs, uses and seeking behaviours are still very scarce in the music information retrieval (MIR) and music digital library (MDL) fields. We are conducting a multigroup survey in an attempt to acquire information that can help eradicate false assumptions in designing MIR systems. Our goal is to provide an empirical basis for MIR/MDL system ...

As more online databases are integrated into digital libraries, the issue of quality control of the data becomes increasingly important, especially as it relates to the effective retrieval of information. Authority work, the need to discover and reconcile variant forms of strings in bibliographic entries, will become more critical in the future. Spelling variants, misspellings, and transliterat...

One critical aspect of an information system is indexing, that is, the representation of concepts to get a well formed data structure for search. Until recently, this task was accomplished by creating a bibliographic citation that references the original text. This approach allows a reduction in time and space bounds, although it does not facilitate the user from finding relevant information. I...

The objective of this paper is to demonstrate the reuse of digital content, as video documents or PowerPoint presentations, by exploiting existing technologies for automatic extraction of metadata (OCR, speech recognition, cut detection, MPEG-7 visual descriptors, etc.). The multimedia documents and the extracted metadata are then indexed and managed by the Multimedia Content Management System ...

Historically, researchers have not fully capitalized on the potential synergies that exist between bibliometrics and information retrieval (IR). Knowledge of regularities in information production and use, as well as citation relationships in bibliographic databases that are studied in bibliometrics, can benefit IR system design and evaluation. Similarly, techniques developed for IR and databas...
