Thesauri on the Web: current developments and trends

This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed

Natural language processing

Beginning with the basic issues of NLP, this chapter aims to chart the major research activities in this area since the last ARIST Chapter in 1996 (Haas, 1996), including: (i) natural language text processing systems - text summarization, information extraction, information retrieval, etc., including domain-specific applications; (ii) natural language interfaces; (iii) NLP in the context of www and digital libraries ; and (iv) evaluation of NLP systems

Kerja baikpulih bangunan komersial yang terbengkalai di kawasan Melaka Tengah

Industri pembinaan merupakan satu sektor yang menjadi pemangkin kepada pertumbuhan sosio-ekonomi dan sebahagian besar sumbernya digunakan kearah pembangunan yang pesat dalam pentadbiran negara. Projek-projek mega seperti Kuala lumpur internationa airport (KLIA), Pusat pentadbiran kerajaan di putrjaya dan banyak lagi pembinaan bangunan komersial yang menjadi tanda aras perkembangan yang memberangsangkan. Selain dari itu, pembangunan bagi sesuatu kawasan menyebabkan pertambahan penduduk. Ini menunjuk industri binaan merupakan salah satu sektor yang menyumbang dalam pembangunan dari aspek sosial dan ekonomi kepada sesuatu kawasan. Walaupun banyak teknologi dalam industri pembinaan telah digunakan pada masa kini, ia masih lagi tidak dapat mengawal kehadiran bangunan yang terbiar di Malaysia dan kesan kewujudan bangunan terbiar itu mengakibatkan kerugian kepada pelbagai pihak dan mengancam keselamatan penduduk sekitarnya

Conceptual design study for an advanced cab and visual system, volume 2

The performance, design, construction and testing requirements are defined for developing an advanced cab and visual system. The rotorcraft system integration simulator is composed of the advanced cab and visual system and the rotorcraft system motion generator, and is part of an existing simulation facility. User's applications for the simulator include rotorcraft design development, product improvement, threat assessment, and accident investigation

Survey of Federal, National, and International standards applicable to the NASA applications data services

An applications data service (ADS) was developed to meet the challenges in the data access and integration. The ADS provides a common service to locate and access applications data electronically and integrate the cross correlative data sets required by multiple users. Its catalog and network services increase data visibility as well as provide the data in a more rapid manner and a usable form

A Classification Model for Reusable Software Components

TIris paper presents work which has been carried out in the ESF-ROSE project (referred to as ROSE in the remainder of this paper). Funded under the Eureka programme (Eureka is the famous interjection used by Archimedes in his bath and not an acronym), the ESF project (Eureka Software Factory) aims at providing a highly effective software manufacturing environment The use of the wordfactory in the software context has very little connection to traditional assemblyline factories. Instead, a Software Factory is a factory in the modem sense providing Computer Integrated Software Manufacturing with emphasis on integration. A software factory covers the total software production process, including all technical and managerial tasks, with a high degree of automation and resource utilization. The ROSE project is a collaborative effon involving MATRA Espace, the software house Serna Group (France), and the University of Dortmund (Federal Republic of Gennany). Pan of the work on classification is the Ph.D. research of author Eric Rames. The main goals of the ROSE project (Reuse Of SoftwarE) are: • to analyze and to define in a comprehensive way the concept of software reuse; • to develop an environment for the reuse of software components within a factory. A precondition for reuse in software development is the existence of libraries of reusable software components. In order to suppon reuse, the collection must contain not only the components themselves, but also be accessible by a system that provides descriptions of the components and retrieval mechanisms so that users may match their specific requirements against these descriptions. Indexing reusable software components according to a classification scheme allows reusers to have a better understanding and more efficient access to the libraries' contents. Therefore a classification scheme is built so that it represents selection criteria the reuser might have. These indexes would be searchable and keyed to retrievable software descriptions. Based on retrievals, users may then access the actual software. Building such a collection is a domain analysis process [PRI90] that includes activities such as: • Identification of software components that should be reusable and description in terms of reusable software components. • Definition of a classification scheme appropriate for indexing and retrieving the reusable software components. TIris paper focuses on the latter topic and how it is performed in the ROSE project. A case study carried out from the aerospace domain is then presented. A discussion of ongoing and future work will conclude this paper

Computer-Aided Knowledge Engineering for Corporate Information Retrieval

In 1987, Digital Equipment Corporation's internal Madret Information Services Group I Information Access Services (lAS) decided to build a single thesaurus system to support production and retrieval of multiple applications. This system TIMS (Thesaurus I Indexing Management System) bad to be dynamic and allow for easy modification and merging of volatile business terminology. A faceted approach was used for knowledge-base building and semantic representation. 1be system allowed the knowledge engineer to determine a classification structure and to develop relation types suited to a specific application's requirements
