Direction relationship is one of the fundamental elements of spatial reasoning, spatial semantics matching, fuzzy query of spatial relationships and object-oriented image analysis. Due to their natural uncertainty and complexity, modeling directional relations keeps being challenged. This work proposes a new fuzzy model for representing cardinal direction relations based on topological reference....
The importance of bridging the gap between the connectionist and symbolic paradigms has been widely recognized. In this paper, we present a new connectionist model called CML2 for 2-dimensional modal logic program. After proposing a fix-point semantics of the logic program, we put forward an algorithm to build the CML2, which encodes the background knowledge represented by a 2-dimensional modal logic...
P2P reasoning system can answer queries from not only each peer's local theory but also some other peers related with sharing part of its vocabulary. This paper concentrates on P2P reasoning technology based on description logic, trying to provide an intelligent solution for searching network resources. A P2P reasoning algorithm suitable for description logic called DL-DeCA is proposed in this paper,...
Eliciting and describing complex business process consistently and unambiguously is important and critical for migrating complex business processes to cloud platform. Mspoa (Subject Predicate Object Adverbial complex business process description Meta-model) is proposed in this paper, which can represent the static relationship in business process description problem space. Based on Mspoa, clewed and...
Data quality is a critical problem for the Semantic Web. We propose that the degree to which a triple deviates from similar triples can be an important heuristic for identifying errors. Inspired by data dependency, which has shown promise in database data quality research, we introduce Semantic Dependency to assess quality of Semantic Web data. The system first builds a summary graph for finding candidate...
To better support information integration on Semantic Web data with varying degrees of quality, this paper proposes an approach to detect triples which reflect some sort of error. In particular, erroneous triples may occur due to factual errors in the original data source, misuse of the ontology by the original data source, or errors in the integration process. Although diagnosing such errors is a...
The proposal and development of semantic web make ontology, as a new knowledge organization and semantic description method, get attention in various fields. The building of ontology is a basic and important task in semantic web. The construction method and organizational structure of ontology will directly affect the application of ontology. Based on the analysis of hierarchical characters existing...
Ontology Model and Semantic Link Network (SLN) are two important semantic data models in Semantic Web. Ontology Model can describe network resource in concept space, while SLN can describe various links and relations between network resources. Combination of Ontology Model and SLN can help to improve the effect of network resource retrieval, but data transfer and exchange between ontological knowledge...
In mass services environment, how to schedule resources efficiently and reliably in the Fourth Party Logistics is a hot topic recently. Semantic web and web service technology are introduced into our project on the background of 4PL. The starting point of our work is to define service conceptions, semantic matching and reasoning in logistic. Then, two-stage solution algorithm (TSSA) is proposed which...
