Access control is an important issue among the security problems of resources in distributed systems. In order to enable entities in distributed systems to understand and interpret policies correctly, common concern is drawn to the problem of expressing access control policies with semantic information. In this paper, we introduce how to express access control policies based on OWL and SWRL. It...

Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...

In this paper we present a prototypical implementation of a graphical tool for creating and editing (DL-safe) SWRL rules. The tool uses a graphbased approach to model rules expressed in the SWRL language. Rules are built from concepts and roles defined in an OWL ontology. Such a knowledge base can be visualised and edited in a user-friendly interface. Moreover, the presented tool provides metho...

The paper presents a metamodel-driven model transformation approach to interchanging 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 bidirectional transfor...

В статье описаны результаты разработки алгоритма обнаружения аномалий временных рядов с учетом особенностей предметной области. Алгоритм предполагает нахождение прогноза использованием LSTM-сетей, обнаружение по полученному прогнозу, фильтрацию найденных в соответствии возможными отклонениями значений временного ряда от тренда, отраженными онтологии, и логический вывод результатов поиска набора...

In this paper,according to the characteristics of maize disease knowledge,OWL DL language was used to build maize diseases ontology, and the reasoning rule of maize diseases was defined by using the expressive ability of SWRL rule language.The author introduced several realizable reasoning functions,and achieved the diagnostic reasoning of maize disease knowledge by Jess inference engine.The re...

Nowadays rule-based systems are very common. The use of ontology-based systems is becoming ever more popular, especially in addition to the rule-based one. The most widely used ontology development platform is Protégé. Protégé provides a knowledge acquisition tool, but still the main issue of the ontologybased rule system is rule acquisition. This paper presents an approach to using SWRL rules ...

Various strategies and techniques have been proposed for the generation of questions/answers tests in Intelligent Tutoring Systems by using OWL (Web Ontology Language) ontologies. Currently there have been no known methods to utilize SWRL rules for this task. This paper presents a system and a set of strategies that can be used in order to automatically generate multiple choice questions from S...
