“…However, it is not our intention to direct the generation of the repositories by the analysis of physical data alone. We intend to develop a declarative Repository Defmition Language [26], Statements of this language, combined with the physical data, together would determine the structure of InfoHamess repositories.…”

“…Our main objective in constructing the InfoHarness system is to provide rapid access to huge amounts of heterogeneous information in a distributed environment without any relocation, restructuring, or reformatting of data. Many researchers have investigated the use of metadata to support run-time access to the original information [1,3,8,9,11,12,13,19,26]. Others [5,11,21,27] have investigated the use of data mining for the automatic extraction of metadata.…”

The InfoHarness TM system is aimed at providing integrated and rapid access to huge amounts of heterogeneous information independent of its type, representation, and location. This is achieved by extracting metadata and associating it with the original information. The metadata extraction methods ensure rapid and largely automatic creation of information repositories. A stable hierarchy of abstract classes is proposed to organize the processing and representation needs of different kinds of information. An extensible hierarchy of terminal classes simplifies support for new information types and utilization of new indexing technologies. InfoHamess repositories may be accessed through Mosaic or any other HyperText Transfer Protocol (Hqq'P) compliant browser.

The burgeoning amount of information available via the Internet has heightened awareness of the need for improved tools for resource identification.The U.S. National Library of Medicine's (NLM) Sourcerer project is developing software which accepts a user query, automatically identifies appropriate information resources, and facilitates connection to those sources for information retrieval. The current Sourcerer prototype utilizes the multimedia/multiplatform/ multiprotocol network-based hypertext system known as World Wide Web. It also relies upon the knowledge sources of the Unified Medical Language System (UMLS). The UMLS is the result of a long-term project of NLM. It comprises a large Metathesaurus of biomedical concepts (coupled with a semantic network and syntactical/lexical software tools) and the Information Sources Map (ISM), a database of records describing specific biomedical information resources. Recent advances in the standardization of information exchange over computer networks, coupled with the tools provided by UMLS, facilitate query refinement and augmentation, connection to resources, and retrieval from resources. Daunting challenges remain with respect to optimizing resource descriptions, defining optimal algorithms for searching for sources, optimizing user interface design, and organizing retrieved information.
