TERRAS is a Java library that allows to filter and rank a list of objects by measuring their matching against a set of demands. If the demands are some user's preferences, then TERRAS can be useful for service personalization.
Features:
- Evaluates the affinity of a set of candidate resources to a given query
- Descriptions of candidate resources can be given as RDF/XML or N3 files, or a remote SPARQL endpoint
- Ability to execute matching against remote repositories of RDF descriptions using SPARQL endpoints
- Expressive query language which allows to define necessary and optional constraints, and to assign arbitrary weights to optional constraints. Constraints can contain datatype restrictions (e.g., numerical comparison), cardinality restrictions, existential restrictions
- Two implementations of the matching algorithm with different performance profiles
- Reasoning support for OWL-DL compliance
- Completely domain-independent. Domain ontologies can be plugged in as needed
