Organizing the Internet

This paper examines XML and its relationships with SGML (Standardized General Markup Language) and HTML (HyperText Markup Language). It examines the importance of metatags and the XML Document Type Definition (DTD) and proposed alternatives. It looks at the differences between the two types of XML data: “valid” and “well-formed” documents

GATE -- an Environment to Support Research and Development in Natural Language Engineering

We describe a software environment to support research and development in natural language (NL) engineering. This environment -- GATE (General Architecture for Text Engineering) -- aims to advance research in the area of machine processing of natural languages by providing a software infrastructure on top of which heterogeneous NL component modules may be evaluated and refined individually or may be combined into larger application systems. Thus, GATE aims to support both researchers and developers working on component technologies (e.g. parsing, tagging, morphological analysis) and those working on developing end-user applications (e.g. information extraction, text summarisation, document generation, machine translation, and second language learning). GATE will promote reuse of component technology, permit specialisation and collaboration in large-scale projects, and allow for the comparison and evaluation of alternative technologies. The first release of GATE is now available

Multiple hierarchies : new aspects of an old solution

In this paper, we present the Multiple Annotation approach, which solves two problems: the problem of annotating overlapping structures, and the problem that occurs when documents should be annotated according to different, possibly heterogeneous tag sets. This approach has many advantages: it is based on XML, the modeling of alternative annotations is possible, each level can be viewed separately, and new levels can be added at any time. The files can be regarded as an interrelated unit, with the text serving as the implicit link. Two representations of the information contained in the multiple files (one in Prolog and one in XML) are described. These representations serve as a base for several applications

EDI - XML Standards and Technologies in the Agri-Food Industry

Due to globalisation, the new technological developments and the complexity of food supply processes, the European food sector is increasingly becoming more complex. The consumers’ trust in food, triggered and affected by a number of food crises, is low. Today, consumers increasingly expect safe and high quality food and demand information about the origin of their food. Also, the economic health of the food industry can be greatly affected by food crises; therefore, efficient and effective mechanisms are required to assist the food industry in tracking and tracing products along the food chain. In this paper, we discuss the criteria for an efficient and effective traceability system from an IT perspective (mainly data exchange) and we identify key requirements for ICT enabled traceability

Development of Use Cases, Part I

For determining requirements and constructs appropriate for a Web query language, or in fact any language, use cases are of essence. The W3C has published two sets of use cases for XML and RDF query languages. In this article, solutions for these use cases are presented using Xcerpt. a novel Web and Semantic Web query language that combines access to standard Web data such as XML documents with access to Semantic Web metadata such as RDF resource descriptions with reasoning abilities and rules familiar from logicprogramming. To the best knowledge of the authors, this is the first in depth study of how to solve use cases for accessing XML and RDF in a single language: Integrated access to data and metadata has been recognized by industry and academia as one of the key challenges in data processing for the next decade. This article is a contribution towards addressing this challenge by demonstrating along practical and recognized use cases the usefulness of reasoning abilities, rules, and semistructured query languages for accessing both data (XML) and metadata (RDF)

Recent development in XML-IR

The Web is characterized by a huge amount of heterogeneous data sources, which have different media support and format representation. Because XML can represent files of different formats, it can play an important role in IR since it is becoming a standard form for data representation and exchange over the Web. Under this assumption, the problem of querying heterogeneous sources can be reduced to the problem of querying XML data sources. This paper shows the influence of XML on the IR techniques and methodologies during the last five years through serving over 400 papers published in different conferences and journals
