FluentEditor for OWL0.2.0 - Download

FluentEditor for OWL is comprehensive tool for editing and manipulating complex ontologies using Controlled Natural Language. Fluent editor provides alternative to XML-based OWL editors that is better suitable for human users.

It''s main feature is using Controlled English as a knowledge modeling language. Supported via Predictive Editor prohibits one to enter any sentence that is not grammatically or morphologically correct and actively help the user during sentence writing. The Controlled English is a subset of Standard English with restricted grammar and vocabulary in order to reduce the ambiguity and complexity inherent in full English.

There are dozens known ontology-editors and the number of them is growing from day to day. The most famous is Protégé that allows editing ontology and inspect the inferred knowledge. Both Protégé and Fluent Editor allow support of knowledge engineering. The main difference between Fluent Editor and Protégé however lies in the way how the user interacts with the editor. To understand the meaning of formally ascribed knowledge one is required to have a background in the field of a formal method, especially in logic. It is hard to trace a formal knowledge for any authority that does not have such background. On the other hand, without the support of formal methods it is almost impossible to trace and understand the impact of even small changes of in the knowledge. This pragmatic observation of need for a “human-readable language” knowledge modeling language led us to develop Fluent Editor. When using Fluent Editor, users do not need any training in formal logic formalisms nor the ICT support when using Fluent Editor. They are continuously checked if the entered knowledge fulfills the grammar. Additionally, knowledge engineers are provided with ability to explore the knowledge due to embedded HermiT reasoner that constantly checks the consistency of the knowledge base.
