The Semantic Web is one of the fastest developing fields within the Information and Communication Technology sector and, as such, under constant examination by scientists and IT professionals. This article aims to provide a better understanding of the applicability of Semantic Web tools and technologies in practice. This aim will be achieved by surveying the recommended and emerging W3C standar...

The article provides an insight into a problem of lexical semantic change. A short historical outline of the development of semantic studies is given. The authors analyze some of the most important stages in the history of the formation of this field. The existing approaches to dealing with form and meaning, namely semasiological and onomasiological ones are discussed. The authors consider the ...

Data integration is one of the older research fields in the database area and has emerged shortly after database systems were first introduced into the business world. In this paper, we briefly introduce the problem of integration and, based on an architectural perspective, give an overview of approaches to address the integration issue. We discuss the evolution from structural to semantic inte...

Abstract—In this paper, the secure BioSemantic Scheme is presented to bridge biological/biomedical research problems and computational solutions via semantic computing. Due to the diversity of problems in various research fields, the semantic capability description language (SCDL) plays and important role as a common language and generic form for problem formalization. SCDL is expected the esse...

The need for fuzzy knowledge bases arises from many application fields, such as trust management. To represent fuzzy data, a syntactic and semantic extension of RDF is proposed. The syntax adds to each triple a truth value. The semantic for Fuzzy RDF and Fuzzy RDF Schema allows to derive truth values for derived statements as well. Fuzzy RDF/RDFS does not aim to become a standard extension to p...

In this paper we describe a framework for classifying and annotating Egyptian Arabic Multiword Expressions (EMWE) in a specialized computational lexical resource. The framework intends to encompass comprehensive linguistic information for each MWE including: a. phonological and orthographic information; b. POS tags; c. structural information for the phrase structure of the expression; d. lexico...

The focus of this article is the integration of two different perspectives on lexical semantics: Discourse Representation Theory's (DRT) inferentially motivated approach and Semantic Emphasis The-ory's (SET) lexical field based view. A new joined representation format is developed which is exemplified by analyses of German verbs. The benefits thereof are on both sides. DI/T gains basic entries ...

Image retrieval by content is characterized by the ability of a system to retrieve relevant images based on their visual or their semantic contents. In this paper, we survey key contributions in the medical imaging area. We centre our attention on one related sub-fields: the semantic indexing process. We describe limitations of visual approaches and provide taxonomy for semantic ones with an em...

Over the last two decades or so, Natural Language Processing (NLP) has developed powerful methods for low-level syntactic and semantic text processing tasks such as parsing, semantic role labeling, and text categorization. Over the same period, the fields of machine learning and probabilistic reasoning have yielded important breakthroughs as well. It is now time to investigate how to leverage t...
