Ontologies Alignment Tool
The Ontologies Alignment Tool (OAT) enables end users to easily specify mapping rules through the user friendly interface provided.
The system developed supports the whole alignment process, including:
- Loading Ontologies
- Manage Candidate Mapping Rules
- Manually specified Mapping Rules
- Saving Mapping Rules
A video presenting the OAT is available at the following Link: Open-OAT-Video.
The system enables users to provide mappings among their elements based on an "extended" / "adapted" version of Correspondence Patterns. More precisely it enables end users to:
Easily specify the elements participating at each side of a mapping rule, by instantiating the appropriate Ontological Patterns.
Capture additional information for each mapping rule, such as its origin.
The system automatically produces candidate correspondences among elements.
It based on their labels incorporating a variety of string-based techniques for similarity detection, including tokenization, elimination, stemming, edit distance, among others.
It also take into account the formal description of ontological elements, such as domain and range or classification of terms for producing not only 1 to 1 correspondences but also more complex ones.
Correspondences automatically produced by system are being updated taking into account those specified or those rejected.
