While geographic search filters exist, few of them are validated and there are currently none that focus on Germany. We aimed to develop and validate a highly sensitive geographic search filter for MEDLINE (PubMed) that identifies studies about Germany. First, using the relative recall method, we created a gold standard set of studies about…

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,…

Discovery layers provide a simplified interface for searching library resources. Libraries with limited finances make decisions about retaining indexing and abstracting databases when similar information is available in discovery layers. These decisions should be informed by student success at finding quality information as well as satisfaction…

Describes a scalable, parallel, relational database-drive information retrieval engine. To support portability across a wide range of execution environments, all algorithms adhere to the SQL-92 standard. By incorporating relevance feedback algorithms, accuracy is enhanced over prior database-driven information retrieval efforts. Presents…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

Discusses the motivation for integrating information retrieval and database management systems, and proposes a probabilistic retrieval model in which records in a file may be composed of attributes (formatted data items) and descriptors (content indicators). The details and resolutions of difficulties involved in integrating such systems are…

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…

Compares the performance of inverted and signature file organizations in handling incrementally specified Boolean queries to an information retrieval system. The discussion covers the impact of more sophisticated signature file organizations, related problems, and possible future work. (65 references) (CLB)

Discusses various categories of software that can be applied to the development of in-house databases on microcomputers, and describes the use of a general purpose package with a procedural language to design a small indexing system called Revelation. The description covers data storage and maintenance, database design, file searching, and system…

Presents a dBASE III searching/micro tip that will reveal whether any journals listed within a capture log file are in local holdings. An example gives the commands needed to use the ISSN field in the citations to search a local holdings database. (DB)

Describes a study that examined the ability of the dBase database management system to perform secondary key retrieval on multivalued data items. The results are presented as time cost relative to the number of matching records, and situations in which a different management system might be appropriate are identified. (CLB)

InterBrowse, a uniform interface information retrieval application for several different databases, is designed to be used in Intermedia, a hypermedia environment currently under development at Brown University's Institute for Research Information and Scholarship. This application arose out of the recognized need for an interface that can be used…

Compares two full featured database management systems for bibliographic information in terms of programs and documentation; record creation and editing; online database citations; search procedures; access to references in external text files; sorting and printing functions; style sheets; indexes; and file operations. (four references) (CLB)

Describes the use of askSam, a flexible text based management system, for handling personal collections of bibliographic references. Sample programs and searches are provided for both unstructured (minimum input and programming by the user) and structure applications. (CLB)

A project at Brown University has developed a set of application and system software that provides access to a database of Classical Greek literature which is stored on a CD-ROM. Information on the origins of the project is provided and the technical development of the system is described in detail, including the creation of Classical Greek fonts,…
