Version 1.0 of the SKTI – Target Ontology/Reference Alignment Generator, an ontology matcher evaluation system built for the SKTI project, is a web-based application that allows users to create heterogenous ontologies of the same domain with "golden standard" reference alignments.
Version 1.0 of the SKTI – Synthetc Data Generator, also built for of the SKTI project, is a web-based application that allows users to create synthetic data ( OWL/RDF ) for a given OWL ontology. The user can specify the number of instances and fact relationships to create. The user also has the option to introduce specific types of noise to the dataset.
The OntoMap service enables a user to generate formal correspondences, or rules, that map concepts and data from different but related ontologies. These mapping rules are internally represented with the Web-PDDL language, which is a subset of first-order logic. The Web-PDDL rules are then translated into Ontology Web Language (OWL) format as output to the user.
A prototype of our OntoGrate online service is available for querying relational databases with Semantic Web ontologies. As one application of OntoGrate and comparison with View-based database mediation, we also integrate zebrafish and mouse gene databases: (ZFIN-MGI Integration).
Our inference engine, OntoEngine, and the updated OWL version of the OntoMerge online service are designed to translate Semantic Web data. (Both OntoEngine and OntoMerge were first developed by Dejing Dou and his Yale colleague, Peishen Qi, and their advisor, Drew McDermott. The orginal DAML version of the OntoMerge service can be found here).
Our online syntax translation service, OWL2PDDL, provides bi-directional metadata and data translation between OWL/RDF and WEb-PDDL. We use this translator to integrate AIM Lab applications with standard ontology and ontology data representations.
All of our software uses the Web-PDDL language, an expressive, strongly typed, first-order language for describing semantic mapping rules between different ontologies. Web-PDDL's syntax and semantics are described in this white paper.
