Ontology Based Computation

Ontology based systems provide extraordinary flexibility and adaptability of the business to new requirements for both B2B and C2B applications. The main advantage of this approach is “capture the business rules and knowledge once and use it in many different ways”. The one-time investment in the development of the ontology pays repeatedly each time you need to make any change in the business rules.

VIStology provides consulting as well as development and support services to businesses in the area of new information technologies. In particular, VIStology specializes in development of ontologies that capture the business rules and the domain knowledge of the business as well as development and support of re-engineering of information systems to ontology based systems, including annotation of incoming information in the language of the ontology, integration and fusion of information coming from multiple and disparate sources, semantic web services and flexible query answering using generic logic-based reasoners.

BaseVISor

BaseVISor is VIStology's versatile forward-chaining rule engine specialized to handle facts in the form of RDF triples with support for RuleML, R-Entailment and XML Schema Datatypes. BaseVISor 1.0 is licensed for academic and research use free of charge; all other uses require a commercial license obtainable through VIStology, Inc.

ConsVISor

ConsVISor is a rule-based system for checking the consistency of ontologies and annotations serialized in RDF or OWL. ConsVISor can also warn the ontologist about elements that, while not necessarily inconsistent, may not be what was intended. For example warnings are issued when a class is used but not declared, a resource has a predicate but it was not declared to be a statement or an entity was declared to be disjoint with another, but it was not declared to be a class. ConsVISor is provided as a free Web Service at http://www.vistology.com/consvisor.
