An Object-Oriented Database for the Display Measurement and Analysis System
Authors: Yihong Qian, Edward A. Fox, Willard W. Farley
Venue: CIKM
Year: 1993

This paper describes development of an Display Measurement and Analysis System (DMAS). An object data model for DMAS has been specified, and a prototype database subsystem has been implemented using the ObjectStore ODBMS, accessed from a Windows graphical user interface. The DMAS database was designed to be fully object-oriented to support complex data modelling capabilities and easy extension. Research endeavors include exploring ODBMS in this unconventional engineering application domain and development of an object data model and a testbed for display measurement systems.
Interoperable Query Processing with Multiple Heterogeneous Knowledge Servers
Authors: Louiqa Raschid, Yahui Chang, Bonnie J. Dorr
Venue: CIKM
Year: 1993

This paper describes a technique for information mediation when multiple heterogeneous knowledge and data servers are to be accessed during query processing. One problem is building an intelligent interface between each knowledge server (KS) and its processor (KP); and the second is to provide interoperability among multiple KP/KS so that a query may be answered using information from multiple sources. We present example scenarios which highlight these problems and then outline query mapping and transformation techniques that are applicable. The techniques for solving the interoperability problems involve representations in some canonical form. This includes a canonical representation (CR) corresponding to each KP/KS pair and a merged CR (MCR) to represent the mapping among the CRs. The MCR and CRs include relevant information obtained from a source query, and heterogeneous mapping (het-map) information, for all possible mappings among the multiple servers. The knowledge in the canonical form must be represented so that it can be easily during query transformation.

Tools for View Generation in Object-Oriented Databases
Authors: Elke A. Rundensteiner
Venue: CIKM
Year: 1993

This paper discusses two aspects of the objectoriented view management system, Multi View, which we designed to simplify view specification. First, we iniroduce a query language for view customization that operates on a complete schema, rather than deriving only individual virtual classes. This graph algebra promises to reduce the effort involved in view specification by lowering the number of queries necessary to dejine a view. Second, we introduce a tool that guarantees the composition of view classes into arbitrarily complex, yet consistent, view schemata. Unlike for relational views, generalization relationships in 00 views must be validated so that they are consistent with the global schema. In our system, we solve this problem by reformulating view schema construction as a classical graph theory problem, called minimal covering. This allows us to develop eficient algorithms that automatically generate a complete, minimal and consistent view schema. Proofs of correctness of these algorithms can be shown.
Multi-media RISSC Informatics: Retrieval of Information with Simple Structural Components (Part I: The Architecture)
Authors: Daniela Rus, Devika Subramanian
Venue: CIKM
Year: 1993

This paper presents a novel architecture for building special-purpose agents for solving the information capture and access problem in large, unstructured data environments with uncertainty in data representation and interpretation.The key idea is to recognize and use underlying structure in such environments using simple components with specified performance guarantees connected by effective communication protocols.This paper brings together ideas from systems and theory: the design of mobile robots in unstructured physical environments, work in electronic libraries and know bets, topology, as well as the rich research in information retrieval and filtering to design a concrete software architecture for solving a wide range of highlevel user queries in multi-media environments.

A Recovery Scheme for Multidatabase Systems
Authors: Peter Scheuermann, Hsiang-Lung Tung
Venue: CIKM
Year: 1993

A Multidatabase System (MDBS) is a software package that integrates a number of pre-existing, au-tonomous and heterogeneous Local Database Systems (LDBS). Ensuring the consistency of global transac-tions in the case of failures is a difficult problem due to heterogeneity and to the presence of local transac-tions at the recovering LDBSS. We present a recovery scheme for MDBS that guarantees the correctness of persistent data in the presence of transaction failures, MDBS failures or site failures. Our scheme employs a global commit protocol which can be supported at minimum cost and ensures a higher degree of local autonomy as compared to alternative schemes.
Efficient Maintenance of Rule-Derived Data through Join Pattern Indexing
Authors: Arie Segev, J. Leon Zhao
Venue: CIKM
Year: 1993

In intelligent database systems, knowledge-directed inference often derives large amounts of &amp; @ and the efficiency of query processing in these systems depends upon how the derived data are maintained, This paper focuses on situations where data-deriving rules are conditional on joins of multiple data objects (or relations) and the derived data are materialized to reduce the overall query processing costs. Join indexing is needed for the efficient maintenance of such rule-derived daa but existing join indexing methods are not suitable for this purpose. We develop a family of join indexing techniques-join pattern indexing-- based on a unique construct called join pattern relation. The performance of the proposed join pattern indexing techniques is evaluated to demonstrate their cost effectiveness. 1.
HYKIS - An Information Retrieval System Based on a Hybrid Knowledge Base
Authors: Dongwook Shin, Hyongmuk Lim, Yongun Yoon, Key-Sun Choi
Venue: CIKM
Year: 1993

This paper aims at developing a knowledge-based information retrieval system that allows a naive user to retrieve relevant documents effectively, without any help of a domain expert. For this, it develops a hybrid knowledge base that lets most of heuristics be represented in a simple and structured manner. As knowledge is usually categorized by domain independent and domain dependent one, it separates the store of the knowledge into two bases: domain independent knowledge base (Ibase) and domain dependent knowledge base (Dbase). Ibase is used as a graph-based thesaurus that permits " is-a" relation between index terms. Dbase describes domain-specific information, such as synonym relationship, some term relationships other than "is-a" relation,
Quick and Incomplete Responses: The Semantic Approach
Authors: Chung-Dak Shum
Venue: CIKM
Year: 1993

Conventional query optimization usually minimizes the total time for complete evaluation of a query. We argue that this criterion may not be the only or even necessary requirement. In some interactive environments, a complete answer set may not be required and quick responses to queries can be very desirable. Minimizing the processing time for obtaining a single answer, a few answers, or most answers are identified as other potential optimization objectives. We attempt these optimization problems by adopting a strategy that first looks at places where answers are most concentrated. We are implementing a system (QAns) which provides quick answers to the user. The design of QAns is a loosely couple of a query transformer to a conventional query optimizer. The idea is based on semantic query optimization. However, we introduce an additional logical equivalence in the query transformation process. We target the transformations towards reducing the cost of the set of more expensive operations in the original query plan. Inexact, as well as exact rules are allowed in the transformation. The proliferation of inexact rules also leads to an issue of the `goodness' of such rules. We propose an information-theoretic criterion for incorporating inexact rules in the system.
InfoCrystal: A Visual Tool for Information Retrieval & Management
Authors: Anselm Spoerri
Venue: CIKM
Year: 1993

This paper introduces a novel representation, called the InfoCrystalTM, that can be used as a visualization tool as well as a visual query language to help users search for information. The InfoCrystal visualizes all the possible relationships among N concepts. Users can assign relevance weights to the concepts and use thresholding to select relationships of interest. The InfoCrystal allows users to specify Boolean as well as vector-space queries graphically. Arbitrarily complex queries cart be created by using the InfoCrystals as building blocks and organizing them in a hierarchical structure. The InfoCrystal enables users to explore and filter information in a flexible, dynamic and interactive way.
Word Sense Disambiguation for Free-text Indexing Using a Massive Semantic Network
Authors: Michael Sussna
Venue: CIKM
Year: 1993

Semantics-free, word-based information retrieval is thwarted by two complementary problems. First, search for relevant documents returns irrelevant items when all meanings of a search term are used, rather than just the meaning intended. This causes low precision. Second, relevant items are missed when they are indexed not under the actual search terms, but rather under related terms. This causes low recall. With semantics-free approaches there is generally no way to improve both precision and recall at the same time. Word sense disambiguation during document indexing should improve precision. We have investigated using the massive Word Net semantic network for disambigu at ion during indexing. With the unconstrained text of the SMART ret rieval environment, we have had to derive our own content description from the input text, given only part-ofspeech tagging of the input. We employ the notion of semantic distance between network nodes. Input text terms with multiple senses are disambiguated by finding the combination of senses from a set of contiguous terms which minimizes total pairwise dist ante between senses. Results so far have been encouraging. Improvement in disamblguation compared with chance is clear

Enchancing Knowledge Processing in Client/Server Environments
Authors: Joachim Thomas, Bernhard Mitschang, Nelson Mendonça Mattos, Stefan Deßloch
Venue: CIKM
Year: 1993

A great variety of techniques has been developed to optimize and enhance query processing for relational, client/server, distributed, parallel, and heterogeneous database systems (DBS). Based on that work and experience, we investigate how far those techniques are applicable to query processing in Knowledge Base Management Systems (KBMS). Our reference system is the KRISYS KBMS that consists of a knowledge-processing system at the client (clientbased processing) and a data-processing system at the server (database backend). We describe a unifying framework for query processing incorporating both processing systems (as realized in KRISYS). This allows to distribute and balance the amount of work done in the client and in the server. Based on an evaluation of that framework, several approaches to further enhance knowledge processing are reported.

Rule Validation Based on Logical Deduction
Authors: Ping Wu, Stanley Y. W. Su
Venue: CIKM
Year: 1993

Expert systems and deductive database systems are knowledge-based systems which have the capability of storing andproeessing datartndknowledge rules, and performing logical deductions. The knowledge bases of these systems are usually assumed to be eonsisten~that is, no contradictions are deduced by the system. This assumption is not realistic since, in real-world applications, a knowledge base can contain a large number of rules which pose problems in terms of their ecmsistency. Thus, an automatic knowledge validation procedure is necessary for building a reliable knowledge-based system. In this paper, we present a knowledge validation technique based on the resolution principle to detect inconsistencies of a knowledge base. In this work, we formally define the eoneept of rule base inconsistency and show its relationship with the concept of unsatisfiability in formal logic. We also define completeness of a rule validation algorithm and show that our rule validation method is complete in the sense that it can not only identify all the input facts casing the system to deduee contradictions but also determine the specific subset of rules involved in the deductions of the contradictions. Based on this information, knowledge base designers can then make proper corrections to their knowledge base designs. A rule validation system using the proposed technique has been implemented in Prolog.
Optimization of Object Queries Containing Encapsulated Methods
Authors: Zhaohui Xie
Venue: CIKM
Year: 1993

Optimization of object queries containing encapsulated methods is still an open problem. In some previous studies of object query optimization, encapsulated methods are considered w black boxes and therefore, optimal query evaluation plans may be excluded from consideration. In the others, only methods coded in query languages are taken into consideration during optimization process and the application of methods is, therefore, restricted. In this paper, a systematic way of revealing and exploiting useful information from encapsulated methods is applied in object query optimization.

Text-Hypertext Mutual Conversion and Hypertext Interchange through SGML
Authors: Min Zheng, Roy Rada
Venue: CIKM
Year: 1993

This paper presents an SGML-MUCH (S-M) system, the I/O subsystem of a collaborative authoring and reuse sys-tem called MUCH (Many Using and Creating Hyperme-dia), for text and hypertext mutual conversion and hyper-text interchange. The S-M system can dynamically gener-ate text documents from the MUCH document database by traversing a subgraph of the hypertext database. With various options on traversal, different versions of docu-ments ean be generated from the same set of nodes and links in the document database. The documents generated from the MUCH document database include not only document content but also groupware and hypertext infor-mation that can be used for hypertext interchange. With this generated document, hypertext for different systems such as Guide and Hyperties can be automatically gener-ated and new features, like alternate outline and automati-cally derived indices can also be incorporated. The S-M system, which was developed using several public-domain development tools, adheres to standards where possible, and generally foeuses on ’ openness’. 1.
