Specialised subject gateways have become an essential tool for locating and accessing digital information resources, with the added value of organisation and previous evaluation catering for the needs of the varying communities using these. Within the framework of a research project on the subject, a software tool has been developed that enables subject gateways to be developed and managed. General guidelines for the work were established which set out the main principles for the technical aspects of the application, on one hand, and on aspects of the treatment and management of information, on the other. All this has been integrated into a prototype model for developing software tools. The needs analysis established the conditions to be fulfilled by the application. A detailed study of the available options for the treatment of information on metadata proved that the best option was to use the Dublin Core, and that the metadata set should be included, in turn, in RDF tags, or in tags based on XML.

Using different information systems and correct communication between them are very important problem at this time. Modern companies have a large number of major applications that take care of running the business. At different times, different people used different technologies to write these applications for different purposes. Data resources can be at many different forms in organization: relational databases, object databases, XML documents and etc. Databases can operate with different systems and use distinct software. This problem must be solved by enterprise application integration (EAI) systems. The project analyzes data level EAI. This type of integration is relatively inexpensive and it doesn’t need to incur the expense of changing, testing, and deploying the application. XML can be a powerful ally for data integration. The main purpose of this project was to analyze usage of XML technologies possibilities for data integration. The problem solved is how to use the same XML flow for a several purposes: the change of another database(s), transforming to a HTML document and forming a PDF document for printing. These problems are analyzed and solved in the particular range – organization of management of public utility. Here is designed and realized an information system.

In this work analyzed some standards and technologies according to data transfer processes between different data sources. New database development and usage requires legacy database data integration into new databases. The common integration structure must be created for this purpose. During integration we should pay attention to name conflicts. XML is being used because of its usage flexibility and simplicity. Data exchange using XML enables to ensure data storage for the future regenerative possibility. System realization was used in KTU Computer Cathedral activity.

The Semantic Web is the future of the Internet. It is the extension to the Internet in which information will be given well-defined meaning, enabling not only humans but also machines to find, share and combine information more easily. In the Semantic Web documents are not merely pages containing a set of words that form their content. They also encode the meaning and structure of those words. This enables various information retrieval techniques to be performed on the documents in addition to the ones restricted to keywords. The goal of this research is to explore a method for querying the Semantic Web using relational database theory and source transformation techniques. We take as input, documents annotated with XML mark-up and the information tags that we are interested in. We then extract and populate a relational view on the annotated XML documents using these tags and the implicit relations in the XML documents. We evaluate the feasibility of our system by testing on a variety of input and we also explore the kinds of queries that can be made on the extracted relational view. / Thesis (Master, Computing) -- Queen's University, 2007-09-27 10:56:13.513
