News items play an increasingly important role in the current business decision processes. Due to the large amount of news published every day it is difficult to find the new items of one’s interest. One solution to this problem is based on employing recommender systems. Traditionally, these recommenders use term extraction methods like TF-IDF combined with the cosine similarity measure. In thi...

In this paper an outline of semantic-based modeling and the approach of SeMFIS is given. At its core, semantic-based modeling characterizes the annotation of semi-formal conceptual models with concepts from formal semantic schemata such as ontologies. Semantic-based modeling is used for the design and analysis of information systems where it supports the extension of the semantic representation...

this paper examines the semantic contribution of -?r and -andeh suffixes in persian based on lieber’s (2004) lexical semantic representation. this framework using six semantic features ([material], [dynamic], [location], [ieps] , [b] and [ci] and a principle called coordination principle studies the semantic contribution of lexical items including affixes and their functions in compounding, der...

Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...

Refinement is a method to derive correct programs from specifications. A rich type language is another way to ensure program correctness. In this paper, we propose a wide-spectrum language mixing both approaches for the ML language. Mainly, base types are simply included into expressions, introducing underdeterminism and dependent types. We focus on the semantic aspects of such a language. We s...

One of the most convenient ways to query XML data is a keyword search because it does not require any knowledge of XML structure or learning a new user interface. However, the keyword search is ambiguous. The users may use different terms to search for the same information. Furthermore, it is difficult for a system to decide which node is likely to be chosen as a return node and howmuch informa...

Current Web applications provide their information and functionalities to human users only. To make Web applications also accessible for machines, the Semantic Web proposes an extension of the current Web, that describes the semantics of the content and the services explicitly with machine-processable meta-data. In this paper we introduce an architecture of a Semantic Portal that provides a uni...

This paper describes GermaNet, a lexical-semantic network and on-line thesaurus for the German language, and outlines its future extension and use. GermaNet is structured along the same lines as the Princeton WordNet (Miller et al., 1990; Fellbaum, 1998), encoding the major semantic relations like synonymy, hyponymy, meronymy, etc. that hold among lexical items. Constructing semantic networks l...
