This paper explores possibilities for marrying data visualization to online archival finding aids, which have continually suffered from usability issues in their long history. This paper describes a project in which two different data visualization models were built to replace sections of an archival finding aid. Users were then shown the models,…

Introduction: In the big data age, we have to deal with a tremendous amount of information, which can be collected from various types of sources. For information search systems such as Web search engines or online digital libraries, the collection of documents becomes larger and larger. For some queries, an information search system needs to…

Simulations have been implemented globally in nursing education for years with diverse conceptual foundations. The aim of this scoping review is to examine the literature regarding the conceptualizations of learning and pedagogical models in nursing simulations. A scoping review of peer-reviewed articles published between 2000 and 2013 was…

With the advent of the Web, the notion of "information retrieval" has acquired a completely new connotation and currently encompasses several disciplines ranging from traditional forms of text and data retrieval in unstructured and structured repositories to retrieval of static and dynamic information from the contents of the surface and deep Web.…

Addresses foundations of designing a bibliographic database for casual end-users, including the representation of knowledge, hierarchical schemata, cognitive processing of search problems, basic level categories of knowledge, and Boolean strategy in online searching. A hierarchical-based query model, data-item model, and idealized data model for…

Discussion of commercial document/information retrieval models focuses on the fact that document retrieval, specifically access to intellectual content, is a complex process which is most strongly influenced by the size of the document collection, the type of search (exhaustive, existence or sample) and the determinacy of document representation.…

Discussion of XML focuses on indexing techniques for XML documents, grouping them into flat-file, semistructured, and structured indexing paradigms. Highlights include searching techniques, including full text search and multistage search; search result presentations; database and information retrieval system integration; XML query languages; and…

Presents a new model for combining multiple sources of evidence in database merging based on logistic regression, and occurring only when ranks are available as a key to be used to merge different ranked lists obtained by various retrieval schemes. Results indicate better retrieval effectiveness than other approaches. (LRW)

Three aspects of training and education for online searching of bibliographic and databases are addressed: (1) the present status--what is being taught, (2) a proposed model--what needs to be taught, and (3) the implementation of the model--who should teach what. The first section shows which organizations (library and information schools,…

Proposes a "Model of Querying" for users of office filing facilities and discusses its motivation, aspects, attributes, and advantages. A review of current information systems and attempts to combine information retrieval, artificial intelligence, and database management techniques leads to conclusion that no resultant system is adequate…

Proposes that the development of document-retrieval systems can benefit from the incorporation of conceptual modeling techniques, specifically classification, aggregation, and generalization. An array model is presented which has been designed especially for document retrieval. (Author/EM)

With more than 38,000 references to journal articles, books, book chapters, and reports on Mexican Americans, the Chicano database offers the most comprehensive access to information on one of the largest ethnic groups in the United States. It is a model for other ethnic CD-ROM projects. (SLD)

Describes a study evaluating the effectiveness of the Information Retrieval, Ltd. (IRL) Life Sciences Collection database in a field where BioSciences Information Service (BIOSIS) claims to offer comprehensive coverage of the international literature. The two databases are described, and the depth of controlled indexing is compared for the two

Discusses the problems associated with using connect time as the basis of user fees for searching numeric online databases, and proposes a methodology for user charge estimation based on query formulation and results. (87 references) (CLB)

Examines the processes that occur when a searcher searches for documents in a reference database, and what relationships exist between psychological descriptions of these processes and models from the domain of information retrieval. Highlights include associational psychological modeling; empirical testing; and information science and psychology.…
