Practical development of the intelligent business applications for the Semantic Web requires advanced methods and tools for knowledge processing and representation. XML-based languages allow for knowledge specification, however they do not support inference which is the core activity. In the paper it is proposed to apply a new knowledge representation for expert systems, the eXtended Tabular Tr...

The Semantic Web Rule Language (SWRL) is a W3C member submission rule language for ontologies. It is based on a combination of the OWL DL and OWL Lite sublanguages of the OWL Web Ontology Language with the Unary/Binary Datalog RuleML sublanguages of the Rule Markup Language. In this paper we propose a transformation of SWRL rules into the object-oriented rule language of CLIPS (COOL). The purpo...

This paper presents the design and implementation of a novel geosocial semantic service called “Geosocial SPLIS” (GeoSocial Semantic Personalizing Location Information Service). The service a) gets data about points of interest (POIs) and user profiles from external sources such as Google Places API and Google+, b) adopts the well known schema.org ontology, c) supports a user friendly web edito...

This paper shows how recent developments in the area of the Semantic Web can be used to build the SmartGuide intelligent information system. Contextual data and domain knowledge represented in the RDF, RDF Schema, and RuleML mark-up languages, are used to select relevant information for the user on the web. Large parts of the application are generated automatically from these mark-up languages....

Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and inconsistent information. Such reasoning is, among others, useful for ontology integration, where conflicting information arises naturally; and for the modeling of business rules and policies, where rules with exceptions are often used. In this demonstration we present a prototype system for defeasible rea...

There exist a great number of business rules engines in the market, each one with its own rules language. As a result, the need of a standard rules definition language is obvious. In this demo paper, the application of a combination of standard business rules languages to develop a business rules management tool, K-Site Rules, is explained. The main goals of this tool are: first, to integrate t...

Tourism is the world’s largest and fastest growing industry. There are conventional tourism service providers which are competitively trying to provide the best travel services to customers based on their interests. The Semantic Web is a major endeavour to enhance the Web by enriching its content with semantic (meta)data that can be processed by inference-enabled Web applications. eTourism is a...

Web-based collaboration (eCollaboration) is becoming increasingly popular. The crucial first step of a consulting collaboration is expert finding. This paper describes the FindXpRT project for finding experts via rules and taxonomies. We implemented rules for a client finding an expert to collaborate with, for an expert’s decision making on whether to collaborate, and for specifying the collabo...

ویلیام شکسپیر، نویسنده رنسانس، متاثر ازکتاب مقدس، روابط انگلستان و اسلام از قرون وسطی-صلیبی تا وآشنا با زبان لاتین، مناقشات متعدد مذهبی، گفتمان جدید اسلامی را درتراژدی هملت آغاز می کند که برپایه قرآن کریم باشد. در این معرفت انسان دررنسانس، مخلوق خدای پاک منزه، بر مبنای رذیلت فضیلت نفس است. بنابراین، کسب تزکیه دردنیا پس مرگ، وبازآفرینی انسانی خوب برای برخی ها وجود داردکه نمایانگرتحول وحرکت دراین...

In this work, we present the design and implementation of a system for proof explanation in the Semantic Web, based on defeasible reasoning. Trust is a vital feature for Semantic Web. If users (humans and agents) are to use and integrate system answers, they must trust them. Thus, systems should be able to explain their actions, sources, and beliefs. Our system produces automatically proof expl...
