RDA For Cartographic Resources

The purpose of this workshop is to provide a pragmatic, brief introduction and overview to using RDA to create bibliographic records for cartographic resources. The emphasis will be on differences between RDA and AACR2R and specific examples of bibliographic records

Unit 7: Finding, Creating, and Interpreting Metadata

This unit presents a general overview of metadata, its potential uses and relevant vocabulary. Techniques for finding, using and interpreting complicated metadata are discussed and approaches for efficiently creating and cataloging simple metadata presented

A Geographic Knowledge Representation System for Multimedia Geospatial Retrieval and Analysis

Digital libraries serving multimedia information that may be accessed in terms of geographic content and relationships are creating special challenges and opportunities for networked information systems. An especially challenging research issue concerning collections of georeferenced information relates tO the development of techniques supporting geographic information retrieval (GIR) that is both fuzzy and concept-based. Viewing the meta-information environment of a digital library as a heterogeneous set of services that support users in terms of GIR, we define a geographic knowledge representation system (GKRS) in terms of a core set of services of the meta-information environment that is required in supporting concept-based access to collections of geospatial information. In this paper, we describe an architecture for a GKRS and its implementation in terms of a prototype system. Our GKRS architecture loosely couples a variety of multimedia knowledge sources that are in part represen..

A Geographical Knowledge Representation System (GKRS)for Multimedia Geospatial Retrieval and Analysis

Artificial Intelligence Lab, Department of MIS, University of ArizonaDigital libraries serving multimedia information that may be accessed in terms of geographic content and relationships are creating special challenges and opportunities for networked information systems. An especially challenging research issue concerning collections of geo-referenced information relates to the development of techniques supporting geographic information retrieval (GIR) that is both fuzzy and concept-based. Viewing the meta-information environment of a digital library as a heterogeneous set of services that support users in terms of GIR, we define a geographic knowledge representation system (GKRS) in terms of a core set of services of the meta-information environment that is required in supporting concept-based access to collections of geospatial information. In this paper, we describe an architecture for a GKRS and its implementation in terms of a prototype system. Our GKRS architecture loosely couples a variety of multimedia knowledge sources that are in part represented in terms of the semantic network and neural network representations developed in artificial intelligence research. Both textual analysis and image processing techniques are employed in creating these textual and iconic geographcal knowledge structures. The GKRS also employs spreading activation algorithms in support of concept-based knowledge retrieval. The- paper describes implementational details of several of the components of the GKRS as well as discussing both the lessons learned from, and future directions of, our research

Alexandria digital library: User evaluation studies and system design

The Alexandria Digital Library (ADL) is one of the six digital library projects funded by NSF, DARPA, and NASA. ADL’s collection and services focus on information containing georeferences: maps, images, data sets, text, and other information sources with links to geographic locations. During this study period, three different user interfaces were developed and tested by user groups. User feedback was collected through various formal and informal approaches and the results fed back into the design and implementation cycle. This article describes the evolution of the ADL system and the effect of user evaluation on that evolution. ADL is an ongoing project; user feedback and evaluation plans for the remainder of the project are described
