DARE System: Dialog-based Alignment Repair Engine

Ontology alignment (also called ontology matching) is the process of identifying correspondences between entities in different, possibly heterogeneous, ontologies. Traditional ontology alignment techniques rely on the full disclosure of the ontological models; however, within open and opportunistic environments, such approaches may not always be pragmatic or even acceptable (due to privacy concerns). Several studies have focused on collaborative, decentralized approaches to ontology alignment, where agents negotiate the acceptability of single correspondences acquired from past encounters, or try to ascertain novel correspondences on the fly. However, such approaches can lead to logical violations that may undermine their utility. The DARE system extends a dialogical approach to correspondence negotiation, whereby agents not only exchange details of possible correspondences, but also identify potential violations to the consistency and conservativity principles. Currently, the DARE relies on LogMap's extension for the Conservativity Principle.

Use and Installation

  • This project can be imported into Eclipse or other environments as a maven project or it can be cloned using git clone https://github.com/ernestojimenezruiz/dare-system.git

  • This project depends on the logmap-conservativity project:

    1. Clone repository: https://github.com/ernestojimenezruiz/logmap-conservativity (e.g., git clone https://github.com/ernestojimenezruiz/logmap-conservativity.git)
    2. Run mvn clean install under the logmap-conservativity project folder.

  • To generate a JAR file for the DARE system, run mvn clean install under the dare-system project folder.

  • Dependencies:

    1. Together with the JAR file maven will also generate a folder with the "java-dependencies" (inclusing logmap-conservativity library)
    2. The "lib" folder is also required. The "timeout" programs should be given execution permissions.
    3. The "asp" folder contains the logic programs needed by the SCC repair algorithm
    4. The "resources" folder contains some example ontologies used in the tests

Check out the running example in the kr-2016-release. java -jar dare-system-1.0.0.jar runs the class uk.ac.mas.dare.KR15Environment.
