INFORMATION-RETRIEVAL FROM HYPERTEXT - AN APPROACH USING PLAUSIBLE INFERENCE

INFORMATION PROCESSING & MANAGEMENT 1993年第3期29卷 299-312页

作者： LUCARELLA, D ZANZI, A UNIV MILAN DIPARTIMENTO SCI INFORMAZ I-20135 MILAN ITALY

This paper approaches the problem of information retrieval from hypertext. In this context, the retrieval process is regarded as a process of inference that can be carried out either by the user exploring the hypertext network, browsing, or by having the system exploit the hypertext network as a knowledge base, searching. In the following, a comprehensive model is proposed taking into account both of the perspectives, and combining effectively browsing and querying into a unified framework. Hypertext nodes are regarded as facts, links as rules, and the connected hypertext structure as an inference network that can be used to prove the query inferentially. Next, design and implementation issues are discussed concerning a prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency.

SPREADING THE ILLINET - A DISTRIBUTED NETWORK FOR LIBRARY RESOURCE SHARING IN ILLINOIS

INTERNET RESEARCH-ELECTRONIC NETWORKING APPLICATIONS AND POLICY 1993年第2期3卷 60-68页

Illinois has a national reputation for the innovative use of technology to support library resource sharing. This reputation is based on two successful centralized systems, the ILLINET union catalog and the ILLINET Online distributed circulation system. Nonetheless, a large majority of the state's library systems cannot provide convenient access to, and are themselves not accessible from, ILLINET Online. Thus, statewide library resource sharing is not fully effective. In order to remedy this lack, a plan to migrate to a decentralized network architecture based on TCP/IP communications and the Z39.50 and Interlibrary Loan (ILL) protocol standards is now in the first stages of implementation. This paper describes the development of the plan, explains its rationale, outlines the migration strategy, and, briefly describes the various components of the proposed client-server network.

HYPERMEDIA AND FREE-TEXT RETRIEVAL

引用

INFORMATION PROCESSING & MANAGEMENT 1993年第3期29卷 287-298页

作者： DUNLOP, MD VANRIJSBERGEN, CJ UNIV GLASGOW DEPT COMP SCIGLASGOW G12 8QQSCOTLAND

This paper discusses aspects of multimedia document bases and how access to documents held on a computer-based system can be achieved;in particular, the current access methods of hypermedia and free text information retrieval are discussed. Browsing-based hypermedia systems provide ease of use for novice users and equal access to any media;however, they typically perform poorly with very large document bases. In contrast, query-based free text retrieval systems are typically designed to work with very large document bases, but have very poor multimedia capabilities. This paper presents a hybrid between these two traditional fields of information retrieval, together with a technique for using contextual information to provide access, through query, to documents that cannot be accessed by content (e.g., images). Two experiments are then presented that were carried out to test this approach. Finally, the paper gives a brief discussion of a prototype implementation, which provides access to mixed media information by query or browsing, and user-interface issues are discussed.

TOWARDS A COGNITIVE THEORY OF INFORMATION ACCESSING - AN EMPIRICAL-STUDY

How would users access an 'ideal' computer-based information retrieval system? What strategies would they use in seeking information if they had access to a truly expert knowledge-base which could respond effectively to any kind of questioning, phrased in any way? No such system exists. But this project provided the next best thing-a computer system which allowed unlimited access to genuinely expert knowledge. Unbeknown at the time of learning to 30 volunteer users who accessed the system, the knowledge-base included 2 human experts, communicating with them from a different building, via the computer screen. The interactions between users and the system were logged and analysed. The results reveal a number of different information accessing strategies linked to individual user characteristics and retrieval effectiveness. Implications for the design of improved information retrieval systems are discussed.

QUERYING A HYPERTEXT INFORMATION-RETRIEVAL system BY THE USE OF CLASSIFICATION

We present in this paper a navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems and Information Retrieval systems. Its originality lies in the cooperation of these mechanisms to restrict the consultation universe, to locate faster the searched information, and to tackle the problem of disorientation when consulting the restricted Hypergraph of retrieved information. A first version of the SYRIUS system has been developed integrating both Hypertext and Information Retrieval functionalities that we have called Hypertext Information Retrieval system (H.I.R.S.). This version has been extended using classification mechanisms. The graphic interface of this new system version is presented here. Querying the system is done through common visual representation of the database Hypergraph. The visualization of the Hypergraph can be parameterized focusing on several levels (classes, links, ...).

THE ARCHITECTURE OF A MASSIVELY DISTRIBUTED HYPERMEDIA system

For about fifty years computer science pioneers have dreamt of augmenting the intellect by sharing the collective knowledge of individuals with each other through a global network of machines. However, until recently the technology to implement such a ''global information system'' was not available at reasonable cost. We believe that today's technology and concepts allow the creation of an ambitious information and communication system based on hypermedia principles that can be massively distributed (i.e. over the whole world). This paper first compares the old visions with systems that are available today. Then we describe the architecture of a global, general-purpose hypermedia system by showing how it can be developed using techniques already explored by existing projects. The resulting global information system is specifically designed to operate in the real-world environment of the Internet and makes efficient use of its structure. It is implemented as part of the Hyper-G project currently being performed at the Graz University of Technology.

Three studies were performed on the subject of collaborative learning for students. One of the studies addressed collaborative learning for nursing students and the other two addressed collaborative learning for computer science students. All of the studies investigated novel methods of teaching and learning with emphasis being placed on interaction between students. Results from these studies showed that when students learned collaboratively, they were better able to formulate concrete ideas about the subject material and to eliminate misconceptions.

SCON IS DEAD - LONG LIVE PROJECT-HERMES

引用

GOVERNMENT INFORMATION QUARTERLY 1993年第4期10卷 415-442页

作者： COLLINS, BD C SPAN 400 N CAPITOL ST NWSUITE 650WASHINGTONDC 20001 USA

Today, the Supreme Court of the United States regularly distributes its opinions and orders electronically immediately upon their announcement from the bench. The story of the high court's move into the computer age is not one of overcoming technical problems so much as one of overcoming political problems. The result was that a coalition of legal-information providers and news organizations and associations, called the Supreme Court Opinion Network (SCON), was formed to address the Court's peculiar requirements. This article describes not only the computer system that ultimately emerged, Project Hermes, but also the lengthy and circuitous route the Court felt it necessary to take in achieving a rather straightforward technical goal. This decidedly human story of coalition building and management of perceptions is told from the perspective of one who was at the center of the effort over a four-year period-one of SCON's founding directors and its president.
