This research aims to 1) Develop a common framework for artificial intelligence in higher education (AAI-HE model) and 2) Assess the AAI-HE model. The research process is divided into two stages: 1) Develop an AAI-HE model, and 2) Assessment the model. The sample consists of five experts chosen through purposive sampling. The data is analyzed by…

Annotations play an increasingly crucial role in scientific exploration and discovery, as the amount of data and the level of collaboration among scientists increases. There are many systems today focusing on annotation management, querying, and propagation. Although all such systems are implemented to take user input (i.e., the annotations…

The National Medical Library of Cuba is currently developing an information literacy program to train users in the use of biomedical databases. This paper describes the experience with the course "Cochrane Library: Evidence-Based Medicine," which aims to teach users how to make the best use of this database, as well as the evidence-based…

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…

Shared databases are used for knowledge exchange in groups. Whether a person is willing to contribute knowledge to a shared database presents a social dilemma: Each group member saves time and energy by not contributing any information to the database and by using the database only to retrieve information which was contributed by others. But if…

Discusses end-user searching in Boolean information retrieval systems considers the role of search intermediaries and proposes a model of user preferences that incorporates a user's profile. Highlights include document representation; information queries; document output ranking; calculating user profiles; and selecting documents for a local…

Proposes a conceptual reference architecture for information retrieval systems and discusses functional capabilities of a hypertext environment, based on the proposed architecture, for interaction with large textual databases. Functions of the prototype system HYPERLINE are described, and an example of a user session is provided. (17 references)…

Elicitations study during 40 mediated information retrieval (IR) interactions identified 1557 search intermediary elicitations within 15 purpose categories (requests for information on search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and users' knowledge and previous…

Discusses the shift of information access from a data-centered to a user-centered model and describes the Daltext system, a prototype user-centered information system that allows the user to determine how the data will be viewed (i.e., within a datastream model, a set model, a relational model, and/or a hierarchical model). (Contains 30…

Presents an analysis of information industry alliance formation using environmental scanning methods. Highlights include why libraries and academic institutions should be interested; a literature review; historical context; industry and market structures; commercial and academic models; trends; and implications for information providers,…

In 1996, the Colorado Library Resource Sharing and Information Access Board initiated a project to explore a patron-initiated interlibrary loan (ILL) system utilizing the ACLIN (Access Colorado Library Information Network) infrastructure and interfacing with local catalogs, remote databases, and bibliographic utilities. This report summarizes the…

Characterizes information retrieval systems in a network environment from a user's perspective along two axes: query and presentation. Several examples of early, current, and developing information retrieval systems are considered within this framework, and Daltext, a prototype system to support research on text-based retrieval systems, is…

Discusses information retrieval as an inherently interactive process utilizing a variety of information-seeking strategies on informational and meta-informational levels. An interface design for a bibliographic information retrieval system, called BRAQUE (BRowsing And QUEry), that supports user interactions in a two-level hypertext environment is…

Discussion of information retrieval highlights DalText, a prototype information retrieval system that provides access to nonindexed textual data files where the mode of access is determined by the user based on the task at hand. A user study is described that was conducted at Dalhousie University (Nova Scotia) to test DalText. (Contains 23…
