- Symposium on
- Case-Based Reasoning and Information Retrieval
- Exploring the Opportunities for Technology Sharing
-
- 1993 AAAI Spring Symposium Series
- March 23, 24, 25, 1993
- Stanford University
- Stanford, California
-
- DESCRIPTION:
- The fields of Case-Based Reasoning and Information Retrieval have a
- shared interest in the indexing of information, the formulation of
- query expressions suited to retrieving relevant cases, heuristic
- matching, the measurement of similarity, and the use of domain
- knowledge to improve search. Whereas Case-Based Reasoning research
- has historically worked with small collections requiring a fair degree
- of hand-tailoring of well structured cases, researchers in Information
- Retrieval have concentrated on indexing and querying over very large
- collections of primarily textual data, with the aim of minimizing the
- need for hand-tailoring. Perhaps due to these differences, there has
- been relatively little interaction to date among practitioners in the
- respective fields.
-
- Case-Based Reasoning researchers are now embarking on an ambitious
- second phase whose goal is the implementation of systems that use
- large databases containing a variety of information types. For
- example, a case base with several thousand cases that contain video
- data is currently under development at the Institute for the Learning
- Sciences.
-
- Knowledge-based approaches have been introduced into Information
- Retrieval systems as well, in the form of thesauri, semantic nets,
- concept frames, etc. There is a recent trend in the IR community
- toward extracting and utilizing structured information to complement
- full-text retrieval methods, and to extend textual retrieval systems
- to encompass multi-media.
-
- Not only does the intersection of the two fields appear to be growing
- rapidly, but many tasks (such as text categorization) and many
- application domains (such as legal, medical, help-desk) could utilize
- both IR and CBR, raising the question of how to best integrate the
- methodologies into a single system with a uniform interface.
-
- The purpose of this symposium is to bring researchers from both
- communities together to discuss issues of common interest, share the
- results and experiences of their respective research, and seek areas
- of potential future technology transfer or convergence.
-
- Specific topics of interest include, but are not limited to, such
- questions as:
-
- 1. How might IR integrate and take advantage of more structured information,
- as used in CBR? Can weak and strong retrieval methods be effectively
- combined?
- 2. How does CBR scale up to large collections of semi-structured
- information? How can CBR minimize the need for hand-tailoring of
- the data in a case base?
- 3. What similarity assessment methods and metrics have been developed
- in CBR and IR? What demands do they make on knowledge representation
- schemes?
- 4. How well do CBR/IR techniques apply to multi-media information bases?
- 5. How can the construction of viable queries for retrieving desired
- information be facilitated through CBR methods?
- 6. What kinds of knowledge representations are needed to support reasoning
- (over cases) as opposed to retrieval? What is the role of reasoning
- in retrieval?
- 7. Can/should the functions of textual information retrieval and case-based
- reasoning be integrated into a single application? How can the
- effectiveness of such a hybrid CBR/IR system be evaluated?
-
- The symposium will consist of individual presentations and panel
- discussions with ample opportunity for group discussion.
- Participation will be by invitation only. We will strive for equal
- participation from the two communities, as well as between academia
- and industry. However, we will set higher priority to achieving equal
- participation from the two communities before trying to achieve equal
- participation from academia and industry.
-
- SUBMISSIONS:
-
- Those who wish to make presentations should submit a draft paper, of
- length at most ten pages. All prospective submitters are encouraged
- to contact Evangelos Simoudis (simoudis@titan.rdd.lmsc.lockheed.com)
- or Peter Anick (anick@aiag.enet.dec.com) to discuss how what they
- wish to present is coordinated with the objectives of the symposium.
- Those who wish to attend without presenting a paper should send a
- description of their research interests and a list of related
- publications. Four copies of submissions should be sent to arrive by
- October 16 to:
-
- Evangelos Simoudis
- Lockheed AI Center
