One major attraction of the World-Wide Web is ease with which a relatively untrained user can create or modify hypertext document. However, this same flexibility often causes problems low quality similar to those encountered in software developed by programmers before advent engineering. Evolution has been subject much recent research. It now well understood that large proportion costs arise during maintenance phase. This research aims characterise evolution sites terms new metrics and...

This article describes a new vision of the semantic Web as knowledge management environment introduces requirements, including ability to semiautomatically learn ontologies and extract metadata. The article's general tenor, particularly their scenario demonstrating how might be used, was directed toward identifying using services on Web. pursuit this continues.

Knowledge workers are central to an organization's success, yet their information management tools often hamper productivity. This has major implications for businesses across the globe because commercial advantage relies on optimal exploitation of own enterprise information, huge volumes online and productivity required knowledge work. The Active project addresses this challenge through integrated workspace that reduces overload by significantly improving mechanisms creating, managing,...

The World Wide Web today suffers from a defect that stems its original design. is based on the use of Hypertext Markup Language (HTML), which allows page's author to define broadly how it will look computers across globe. HTML works well in providing common language achieve goal. However, says nothing about what data for, i.e. semantics. effectiveness set be dramatically changed with introduction semantic Web.

This paper describes the use of Citizen Curation to explore ways in which cross-modal experiences can be used and created by museum visitors. defined as individuals groups from outside profession engaging curatorial activities communicate their own ideas stories. Previous work has explored how broaden range voices reflected museum, thereby widening its appeal relevance new audiences. Recent research suggests that experiences, combining visual art with music, enhance cultural experience...

Purpose To describe how semantic knowledge technology can be used to enhance a digital library. Design The paper examines the main research challenges in field of libraries and identifies extent which respond these challenges. Functionality developed within SEKT project ( http://sekt.semanticweb.org ) is an existing development good ontology central such application, describes particular engineering approach adopted. Findings Four broad were identified: achieving interoperability; describing...

The use of task context to guide the delivery information knowledge workers is valuable for improving their efficiency and effectiveness. Moreover, sharing between individuals can aid knowledge. This paper describes research in ACTIVE project which uses support sharing. Machine intelligence techniques are used learn association objects context; how partition a user's into set contexts. Informal processes also important workers, another challenge understand influences choice steps process....

A single-crystal neutron diffraction study of the cubic Laves phase Fe2Zr at 4.2 K has been made using both polarized and unpolarized incident beams. The samples were prepared from high-purity zirconium iron exhibited resistance ratios (rho 293 K/rho K) typically 95, indicative with good long-range order homogeneity. material a Curie temperature 604(2) cell dimension a=7.063(1) AA ambient in agreement previous measurements for this composition by others. saturation magnetization 3.46(1) mu...

This review paper argues that users of personal information management systems have three particularly pressing requirements, for which current do not fully cater: (i) To combat overload, as the volume increases. (ii) ease context switching, in particular, who face frequent interrupts their work. (iii) be supported integration, across a variety applications. meet these four broad technological approaches should adopted an incremental fashion: The deployment unified file system to manage all...

The Internet is a new arena for software development, and has attracted much attention from all sides of the computing community because power offered by its distributed form flexibility. There been substantial interest in finding appropriate techniques to take advantage novel characteristics, which include multi platform operation accessibility all. paper identifies number coherent research areas drawn metrics, HCI hypermedia research, viewpoint team interested Web site metrics. These seem...

How can we solve the problem of information overload in news syndication? This poster outlines path from keyword-based body text matching to distance-measurable taxonomic tag matching, on context scale and practical uses.

Description Logics are commonly used for the development of ontologies. Yet they well-known to present difficulties comprehension, e.g. when confronted with justification a particular entailment during debugging process. This paper describes study into problems experienced in understanding and reasoning Logics. In looked at: functionality object properties; negation, disjunction conjunction Propositional Logic; negation quantification; combination two quantifiers. The related theories...

All modern computers are designed using the 'von Neumann' architecture and built silicon transistor technology. Both technology have been remarkably successful. Yet there a range of problems for which this conventional is not particularly well adapted, new architectures being proposed to solve these problems, in particular based on insight from nature. Transistor has enjoyed 50 years continuing progress. However, laws physics dictate that within relatively short time period progress will...
