Semantic Desktops hold provide intelligent information-management environments that respond to users' needs. An important requirement for developing such environments is that the underlying ontology reflects the users' work context. For specialized work domains, where people deal with rich...

We present iMapping, a diagrammatic zooming and nesting based approach for visually structuring information objects on the desktop with a special focus on personal knowledge management. It was designed based on a set of requirements gathered from the analysis of existing knowledge mapping...

We address the issue of ontology construction and reuse, and regard such processes as collaborative negotiations among stakeholders. A semiotic framework is proposed to model the communication environment. Accordingly, content and expression of an ontology have been clearly distinguished, and...

As an innovative approach for developing and maintaining continuously evolving ontologies in corporate context the Corporate Ontology Lifecycle Methodology aims at providing an intuitive understanding of rising costs per iteration. In this regard having a close look at ontology partitioning...

The tremendous growth in the size of Web has created a challenge to find contextspecific information. After finding a specific content on the Web, users need to explicitly query search engines for the related information. In many cases, millions of generic hits are returned by general search...

Supply Networks in the automotive industry are confronted with a lot of challenges - business and technical ones. One of the technical issues is the heterogeneous and different ICT platforms which are show-stopper to implement enterprise interoperability services. Besides other measures Semantic...

We demonstrate a Web 3.0 application that organizes social events for friends in the larger San Francisco Bay Area using real data from available web sources. We use a collection of techniques that will be at the heart of the next wave of applications on the web; entity extraction, querying...

In the Semantic Web, ontologies play an important role as a means to enable the interlinking and the semantic integration of distributed Web data. These processes can be simplified if the underlying ontologies are modeled by integrating already existing Semantic Web ontologies. This paper...

Corporate Semantic Web aims at bringing semantic technologies to enterprises for gaining, managing, and utilizing knowledge as one of the critical resources for their success in a quickly changing and highly competitive world. It provides solutions in three main application areas for semantic...

Technological advances such as Service Oriented Architecture (SOA) have increased the feasibility and importance of effectively integrating information from an ever widening number of systems within and across enterprises. A key difficulty of achieving this goal comes from the pervasive...
