Conference track contains 16 ontologies from the same domain (conference organization). These ontologies are suitable for ontology matching task because of their heterogenous character of origin. An evaluation process will be supported by SEALS platform, see section below for list of planned evaluation methods. Seven ontologies are involved in the reference alignment: Cmt, ConfTool, Edas, Ekaw, Iasted, Sigkdd, Sofsem.
Results will be available according to OAEI schedule.
Data set is available from this web-page (see below). You can either download them and try them on your own or you can directly use SEALS platform. Both options are possible, however finally you have to wrap your tool against the SEALS client provided via the OAEI main page and run this client against the Conference testsuite. For running the Conference testsuite you will have to specify the following input parameters:
The collection of ontologies is dealing with conference organization. They have been developed within OntoFarm project. 16 ontologies are included; the last one (linklings.owl) is in the OWL 2 profile. Each of them is shortly described in the following table. Ontologies have been based upon three types of underlying resources:
|Name||Type||Number of Classes||Number of Datatype Properties||Number of Object Properties||DL expressivity||Related link|
These ontologies are in English. Based on this collection multilingual collection MultiFarm have been made and included into the OAEI campaign as MultiFarm track. Further, three ontologies (Cmt, Ekaw and Sofsem) from this track has been added into the complex matching track.
Participants will use SEALS platform to deliver their results. Alignments submitted via SEALS platform will be evaluated based on
Further, this year we plan to provide detail analysis in the following two ways
The confidence values for all matches in the crisp reference alignment are 1.0, while the uncertain version of the reference alignment has confidence values that reflect the degree of agreement of a group of twenty people on the validity of the match. Crisp reference alignment contains 21 alignments (test cases), which corresponds to the complete alignment space between 7 ontologies (Cmt, ConfTool, Edas, Ekaw, Iasted, Sigkdd, Sofsem) from the data set. This is a subset of all ontologies within this track (16). Total number of possible test cases is hence 120. There are three variants of reference alignment:
Furthermore, participants can directly submit their 'interesting individual correspondences' ('nuggets') which could represent complex correspondences to organizers of this conference track, for contacts please see below. These correspondences will be evaluated manually.
