Latent semantic analysis (LSA) can be used to create an implicit semantic vectorial representation for words. Independent component analysis (ICA) can be derived as an extension to LSA that rotates the latent semantic space so that it becomes explicit, that is, the features correspond more with those resulting from human cognitive activity. This enables nonlinear filtering of the features, such...

Effective revision tracking is important to maintain and use Semantic Web data for both publishers and readers. Information related to revisions in this setting often contains basic context information, semantic difference summary, and rationale summary. In this work, we present a general architecture for modeling and publishing revision history of social semantic Web data. This model has been ...

Changes of semantics in data sources further complicate the semantic heterogeneity problem. We identify four types of semantic heterogeneities related to changing semantics and present a solution based on an extension to the Context Interchange (COIN) framework. Changing semantics is represented as multi-valued contextual attributes in a shared ontology; however, only a single value is valid ov...

In this paper, we present EachWiki, an extension of Semantic MediaWiki characterized by an intelligent suggestion mechanism. It aims to facilitate the wiki authoring by recommending the following elements: links, categories, and properties. We exploit the semantics of Wikipedia data and leverage the collective wisdom of web users to provide high quality annotation suggestions. The proposed mech...

This paper is concerned with the semantics of so-called plurals extension, a class lexical such as mountains, cliffs, skies, Hebrides, and Pyrenees. While similar on surface to regular plural nouns, they behave differently in certain regards, including their compatibility determiners, interpretation half N partitives possibility occur weak definites. We will argue that extension denote predicat...

The life science industry adopts Semantic Web technology to realize novel applications that reduce product development costs, leverage collaboration in research or improve regulatory submissions. The " ICD-10 explorer " presented in this paper is a Microsoft SharePoint-based application to explore the standard classification of diseases. We demonstrate that Semantic Web technologies help to rea...

The Semantic Grid is an extension of the current Grid in which information and services are given well-defined meaning, better enabling computers and people to work in cooperation. The full richness of the Grid ambition depends upon realizing the Semantic Grid, but it is still, to many, a mysterious hybrid of the Semantic Web and the Grid, both of which are subject to myths and misunderstanding...

The paper presents an application of information content based metrics to compute semantic relatedness of word senses in German. The main contributions are: an annotation study based on a revised definition of semantic relatedness beyond synonymy, an extension of Resnik’s (1995) procedure for computing information content of concepts for strongly inflected languages, an application of informati...

Semantic Link Network (SLN) is a semantic Web model using semantic links—the natural extension of the hyperlink-based Web. The SLN-Builder is a software tool that enables definition, modification and verification of, as well as access to the SLN. The SLN-Builder can convert a SLN definition into XML descriptions for cross-platform information exchange. The Intelligent Semantic Browser is used t...
