We describe the architecture of a novel ontology and rule editor ACE View. The goal of ACE View is to simplify viewing and editing expressive and syntactically complex OWL/SWRL knowledge bases by making most of the interaction with the knowledge base happen via Attempto Controlled English (ACE). This makes ACE View radically different from current OWL/SWRL editors which are based on formal logi...

Semantic not consistency, and knowledge base is difficult to reuse and sharing are the key problems affecting the system development and application. This paper studies how to express the soil fertility level information using of the ontology and generate OWL (Ontology Web Language) document, and how to make use of SWRL (Semantic Web Rule Language) to express inference rules. On this basis, thi...

The Semantic Web Rules Language (SWRL) has recently been proposed as the basic rules language for the Semantic Web. SWRL is unusual in being an undecidable superset of a very expressive description logic OWL DL (SHOIN (D)) and a simple rules language, Datalog. In this paper, we attempt to evolve OWL DL toward SWRL, but cautiously and carefully. We strive to retain practical decidability. We see...

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...

In the present paper we describe the model process of an ontologybased expert system for the control of domotic installations and SWRL rules management. From the domotic system database where the attribute values of each device are stored, a background process converts these values into ontology’s instances representing the system physic devices. From these instances, a software application -kn...

SWRL rules are transformed in two steps for visualization in a subset of Grailog. A Unary/Binary Datalog rule in SWRL presentation syntax is translated to a corresponding PSOA RuleML rule in a RIF-like presentation syntax employing frame formulas. This is then translated to the Graphviz DOT language so that the Graphviz tool can render it visually as a Grailog graph with an object identifier an...

In this paper, we describe a methodology for annotating characters’ emotions in narrative media. Given the semantic annotation of the story, the emotional state of its characters is inferred through SWRL rules that encode the emotion appraisal process. In order to exemplify the model and test the emotional states generated by the SWRL module, we resort to a well-known dramatic situation and we ...

transforming the informal descriptions of SWRL into the built-in elements of protégé4.1 is proposed, and the optimization as well as the validation of the policies are also indicated in this paper. The concept of the built-in elements in protégé4.1 is specified in this paper to indicate the mapping relationships from the informal descriptions of SWRL to the built-in elements of protégé4.1. Acco...

The SWRLTab is a development environment for working with SWRL rules in Protégé-OWL. It supports the editing and execution of SWRL rules. It also provides mechanisms to allow interoperation with a variety of rule engines and the incorporation of user-defined libraries of methods that can be used in rules. Several built-in libraries are provided, include collections of mathematical, string, and ...

The paper presents a metamodel-driven model transformation approach to sharing rules between the Semantic Web Rule Language along with the Web Ontology Language (OWL/SWRL) and Object Constraint Language (OCL) along with UML (UML/OCL). The solution is based on the REWERSE Rule Markup Language (R2ML), a MOF-defined general rule language, as a pivotal metamodel and the bi-directional transformatio...
