- KonferenzbeitragReflective learning in large companies - can it work?(2003) Vladoiu, Mihaela-Monica; Matenciuc-Antonescu, BeatriceA growing number of universities and companies are now becoming focused on promoting learning that is not merely instrumental. These aspirations refer to deep learning, transformational learning, critical learning, intentional learning, reflective learning and lifelong learning. Our primary goal is to present several ways in which lifelong reflective learning can be effectively and consciously promoted within large companies. The term reflection is used with two meanings. One would be the process by which an experience, in the form of thought, feeling or action is brought into consideration (while is happening or subsequently) and the other the creation of meaning and conceptualization from experience and the potentiality to look at things from another perspective (critical reflection). We propose the following solutions: modular classes, open engagement lectures, online live learning, virtual classrooms, action group learning, immersive e-learning applications, project-based e-learning and any valuable combination of these. As industrial experience shows, integration of these models and methods to create a learning and development program and to incorporate it in the daily working schedule provide a consistent solution for education in the long run.
- KonferenzbeitragQuerying tourism information systems in natural language(2003) Berger, Helmut; Dittenbach, Michael; Merkl, DieterWith the increasing amount of information available on the Internet one of the most challenging tasks is to provide search interfaces that are easy to use without having to learn a specific syntax and provides a means for finding what they really want. In this paper we present a query interface for an information system in the tourism domain exploiting the intuitiveness of natural language. Furthermore, we will describe the results and our insights from analyzing the natural language queries collected during a field trial in which the interface was publicly accessible. This analysis shows how users formulate queries when their imagination is not limited by conventional search interfaces with structured forms consisting of check boxes, radio buttons and special-purpose text fields.
- KonferenzbeitragUsing neighborhood information for automated categorization of web pages(2003) Panteleeva, NadejdaIn this paper we discuss several issues related to the influence of expansion of a Web document representation on quality of topical categorization of Web pages. We consider a Web page expansion by using text content of it's linking pages. We show that naive expansion can grab too much noise and essentially harm categorization results. We present the approach to automated pruning of linking Web pages. We report that using our approach in forming a Web page representation always leads to better results than traditional single Web page categorization.
- KonferenzbeitragCluster analysis in multiset spaces(2003) Petrovsky, Alexey B.The paper considers techniques for grouping objects that are described with many quantitative and qualitative attributes and may exist in several copies. Such multi-attribute objects may be represented as multisets or sets with repeating elements. Multiset characteristics and operations under an arbitrary number of multisets are determined. The various options for the objects' aggregation (addition, union, intersection) and the main features of hierarchical and non hierarchical cluster analysis in multiset metric spaces are discussed.
- KonferenzbeitragCapturing semantics from search phrases: Incremental user personification and ontology-driven query transformation(2003) Ermolayev, Vadim; Keberle, Natalya; Plaksin, Sergey; Vladimirov, VladimirReported is the methodology of the semantic transformation of an initial user's search query in the form of key words or key phrases to the resulting query composed of the relevant concepts of the domain ontology. Transformation methodology is based on incremental user profiling. The mapping of a user's keywords to the concepts of the domain ontology is built according to the presented transformation rules. These rules are based on the usage of the rich set of the semantic relationships comprising subsumption, synonymy, instantiation and meronymy provided as the DAML+OIL ontology. ACM research papers domain is chosen for the methodology evaluation. Transformation algorithm is implemented in the research prototype as the combined capability of the query transformation agent and the ontology agent of the intelligent multi-agent information retrieval mediator1.
- KonferenzbeitragOverdraft agreement processing based on XML and its implementation in bankinformation system(2003) Marin, Igor O.; Orekhov, Sergey V.In this paper we present a brief overview of Bank Information System (BIS) market situation in Ukraine. An architectural approach for BIS is proposed. The approach demonstrates how to build the BIS application for credit department of a bank. The paper presents a first step of such system implementation, namely: subsystem for overdraft agreement processing. The subsystem uses XML to describe agreement statements. XML content is processed using XSLT to implement credit commission servicing.
- KonferenzbeitragTools for generation of natural inflected language processors(2003) Mishchenko, Nadiya; Doroshenko, AnatolySupporting multiple languages and natural language processing are of high importance in information systems. This paper discusses software tools for the generation of languages processors (LPs) for the natural inflected languages. The tools are implemented in the LP generator DUAL, which allows for formal specification and reusability of developed components. The declarative language Dual is used to specify words, idioms, and their processing. The paper describes the automatic generation of dictionaries from their specifications in the Dual language and the reusability of software components, which facilitates fast construction of user-oriented software systems for processing of natural inflected languages. The LPs generated are intended for word-for-word translation of domain-specific texts in inflected languages and the generation of frequency lists of words and phrases used in statistical analysis of texts in inflected and analytical languages using Cyrillic or Latin alphabets.
- KonferenzbeitragAn integrated ontology development environment for data extraction(2003) Liddle, Stephen W.; Hewett, Kimball A.; Embley, David W.Data extraction is a necessary technology to deal with the huge and growing collection of unstructured and semistructured information available on the World Wide Web. Ontology-based data extraction is a robust approach, but the construction of ontologies is a technical task requiring the services of a human expert. We present a Java-based tool for the graphical creation and testing of data extraction ontologies. This tool leverages standards such as Java and XML to provide a portable, extensible, maintainable, feature-rich environment. This tool reduces the burden on expert ontology developers and simplifies the task of ontology creation.
- KonferenzbeitragFormal modeling of communication traces(2003) Boroday, Sergiy; Hallal, Hesham; Petrenko, Alexandre; Ulrich, AndreasDevelopment of distributed systems is complicated by the absence of reliable global timing, concurrency, and nondeterminism. To deal with these obstacles log files are produced by an instrumented system facilitating analysis, testing, and debugging. This paper presents a formal framework for the analysis of distributed system logs based on event trace concept. A partially ordered trace of events executed by a distributed system is modeled by a collection of communicating automata. We present an implementation of the analysis approach in SDL based on ObjectGEODE. A formalization of a property of an event trace, being a replica of another trace, is discussed.
- KonferenzbeitragWhere ontology affects information systems(2003) Kaschek, Roland; Zlatkin, SergiyNicola Guarino has coined the phrase ontology driven information systems. This phrase appears to offer ontology based help and guidance for information systems development. In this paper we try to understand better whether, why and where ontology affects information systems. We briefly discuss what kind of help we would appreciate and identify domains of knowledge in information systems development that according to our point of view could benefit from such help. We briefly discuss the following five domains: universes of discourse, information systems resources, information space use, customers, and human inference making.
