    Knowledge acquisition is the foremost procedure in knowledge based systems. It is the procedure whereby non codified human expertise is transferred into a well codified computer program (G. Buchanan and C. Wilkins, 1993). Principally, it involves two major issues. Firstly, the accessing of human expertise from domain experts, and secondly, the converting, or the modeling of this expertise into a `... View full abstract»

    In many class based, object oriented database systems the association between an instance and a class is both exclusive and permanent. Therefore, these systems have serious difficulties in representing objects taking on different and multiple roles over time, and hence cannot model the dynamic knowledge from the real world. The paper describes a novel object oriented database management system, ca... View full abstract»

    Planning by rewriting (PBR) is a new paradigm for efficient high-quality planning that exploits plan rewriting rules and efficient local search techniques to transform an easy-to-generate, but possibly suboptimal, initial plan into a low-cost plan. In this paper, we show in detail the application of the general framework to query planning in distributed environments. As a result, we obtain an scal... View full abstract»

    Enabling database applications to perform intelligent record retrieval is one of the most important issues in database research. From one perspective, this particular issue has also been investigated in artificial intelligence (AI) research. Case-based reasoning (CBR) is an approach in AI that focusses on a similar issue. CBR systems mainly try to find the most similar cases from their case bases,... View full abstract»

    Intelligent agents are being widely employed by users to assist in information retrieval tasks. However, users still suffer from “information overload” and most search engines are limited, particularly in meeting user expectations. We have developed SAIRE (Scalable Agent-based Information Retrieval Engine), which addresses many current search engine limitations. SAIRE employs intellige... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (696 KB)

    Rules are one of the best ways to represent logical relationships among entities. Object oriented modeling is useful for understanding problems and efficiently describing real world concepts. Since a domain expertise always contains a set of concepts and the relationships between them, there has been much research effort dedicated to combine object oriented programming and rule based systems in or...

    Most branches of computer science research are already involved in working rewards collaborative problem solving. In AI, the two fields of knowledge acquisition and distributed AI play a major role. The construction of collaborative knowledge-based systems (cooperative KBSs) needs an important stage of knowledge acquisition from the experts involved in the group activity. On the other hand, distri... View full abstract»

    The paper deals with the development of 2D space maps during navigation in unknown environments by using multiple autonomous mobile robots, which communicate and exchange space and travel knowledge. The 2D map generation is based on the synthesis of shapes extracted from consecutive free spaces. Each shape extracted from a current free navigation space is represented by attributed graphs. Thus, th... View full abstract»

    In any database, description files are essential to understand the data files in it. However, it is not uncommon that one is left with data files without any description file. An example is the aftermath of a system crash; other examples are related to security problems. Manual determination of the subject of a data file can be a difficult and tedious task, particularly if files look alike. An exa... View full abstract»

    The paper proposes a framework for deriving users' profiles of typical behaviour and detecting atypical transactions which may constitute fraudulent events or simply a change in user's behaviour. The anomaly detection problem is presented and previous attempts to address it are discussed. The proposed approach proves that individual user profiles can be constructed and provides an algorithm that d... View full abstract»

    This paper addresses the various issues related to intelligent and cooperative systems. Such systems exchange information in order to achieve a common goal. Furthermore, these systems may be distributed on networks and may present several incompatibilities. To overcome such constraints, we suggest to a way to develop software agent-oriented frameworks that are at the heart of the C-FOAL (Conceptio... View full abstract»

    A model based on the application of the Dynamic Link Architecture (DLA) is presented for the off-line recognition of Chinese characters. It is a revised DLA model employing 4-vector dynamic link assignment instead of the original 3-vector links. A sample set of Chinese characters was used to test the performance of the model under various transformations including translation, reflection, rotation... View full abstract»

    Stronger integration of database technology and data mining has been identified as one of the most important directions in knowledge discovery from databases (KDD) research. Database technology can certainly contribute more than just data preparation for KDD, and there should be ways to further explore new information from data processing. This paper discusses the possibility of using query result... View full abstract»

    The diversity of spatial information systems promote the need to integrate heterogeneous spatial or geographic information systems (GIS) in a cooperative environment. We present an on going research project, called ISIS (Interoperable Spatial Information System), which aims to build an environment to support interoperability of GIS by interconnecting spatial data repositories and spatial processin...

    When combining data from distinct sources, there is a need to share meta data and other knowledge about various source domains. Due to semantic inconsistencies, problems arise when combining knowledge across domains when the knowledge is simply merged. Also, knowledge that is irrelevant to the task of interoperation will be included, making the result unnecessarily complex. An algebra over domain ... View full abstract»

    We propose a formal framework based on description logics as a basis for both modeling multidimensional databases and understanding related reasoning problems and services. We extend a description logic with new constructors for defining operators on cubes together with a representational framework for hierarchically structured dimensions. The constructors we propose correspond in part to the oper... View full abstract»

    Discusses the theoretical foundation for type hierarchy of complex objects to extend modelling concepts, semantics and constraints. Complex objects consist of entities and data-structure instances. We assume general constructions of data structures, i.e. not only sets and tuples but any structuring operators are allowed. Our discussion uses an instance-based data model. Since there may be infinite... View full abstract»

    Searching for information has become an important part of the Internet life. New and more powerful search engines are being built every day for public use. Even though the combined power of these engines are far more advanced than their past alternatives, an average user does not seem to be benefiting fully from the state-of-the-art of search technologies. In this paper, we develop an integrated s... View full abstract»

    Web-based organizations often generate and collect large volumes of data in their daily operations. Analyzing such data involves the discovery of meaningful relationships from a large collection of primarily unstructured data, often stored in Web server access logs. While traditional domains for data mining, such as point of sale databases, have naturally defined transactions, there is no convenie... View full abstract»
