Article history: Received 12 March 2012 Received in revised form 7 October 2013 Accepted 8 October 2013 Available online 18 October 2013 The limited semantics of thesauri and similar knowledge models hinder the searching and browsing possibilities of the bibliographic databases classified with this type of resource. This work proposes an automatic process to convert a knowledge model into a dom...
Researchers conducting systematic reviews need to search multiple bibliographic databases such as MEDLINE and EMBASE. However, researchers have no rational search stopping rule when looking for potentially-relevant articles. We empirically tested a stopping rule based on the concept of capture-mark-recapture (CMR), which was first pioneered in ecology. The principles of CMR can be adapted to sy...
ISSUESIN DISCOVERING KNOWLEDGE IN BIBLIOGRAPHIC databases are addressed. An example of semantic pattern analysis is used to demonstrate the methodological aspects of knowledge discovery in bibliographic databases. The semantic pattern analysis is based on the keywords selected from the documents grouped by bibliographical coupling. The frequency distribution patterns suggest the existence of a ...
The formation of vocabulary evolves within communities, within domains of discourse. However, bibliographic databases have traditionally had one single index created for the entire database, even though bibliographic databases usually cover an arbitrary group of domains of discourse. As an experiment, indexes derived from the language used within one single specialized domain of discourse, a su...
The Internet has made finding evidence for clinical practice fairly easy. Many different types of databases that can be searched for relevant key terms are available for free or for subscription. Bibliographic or library databases contain books, book chapters, reports, citations, abstracts, and either the full text of the articles indexed or links to the full text. Citation databases are specia...
BACKGROUND The work participation of people with chronic diseases is a growing concern within the field of occupational medicine. Information on this topic is dispersed across a variety of data sources, making it difficult for health professionals to find relevant studies for literature reviews and guidelines. AIM The goal of this project was to identify bibliographic databases and search ter...
INTRODUCTION The answer to the question of what a database is and what is its relevance to the scientific research is not easy. We may not be wrong if we say that it is, basically, a kind of information resource, often incomparably richer than it is, for example, a single book or magazine. DISCUSSION AND CONCLUSION As a form of storing and retrieval of the knowledge, appeared in the informati...
There are four main differences between the meta-databases for assessment and control systems and databases for bibliographic systems, and the like. The first is the need for speed in generating and updating the meta-database. Secondly there is the spatio-temporal aspects of the information handled. The third difference is the large volume and variety of information to be managed and to be tran...
This three year project demonstrated improved access to written material and numerical data on the same topic when searching two very different kinds of databases (books, articles, and their bibliographic records) and numerical data (socio-economic databases). Also, search support was developed for transverse searching whereby data found in a text database can be used to find related data in a ...
One of the biggest obstacles for information dissemination to a user community is that many Digital Libraries (DL) or bibliographic databases use heterogeneous technologies that inhibit interoperability. The Open Archives Initiative (OAI) addresses interoperability by using a framework to facilitate the discovery of content stored in distributed archives or bibliographic databases through the u...
