چکیده
This paper summarizes the OAEI Contest 2006 results for the matching tool COMA++. The study shows that a generic schema matching system can also effectively solve complex ontology matching tasks. 1 Presentation of the system COMA++ is an extension of our previous COMA prototype [1]. It is a customizable and generic tool for matching both schemas and ontologies specified in languages such as SQL, XML Schema or OWL [2]. COMA++ offers a GUI and supports the combined use of several match algorithms as well as the reuse of previously confirmed match results [6]. The COMA++ architecture is shown in figure 1. The Repository persistently stores all match-related data, the Model and Mapping Pools manage all schemas, ontologies, and mappings in memory, and the Matching Engine performs the match operations. The GUI provides access to these components and is used to visualize models, manage the match process and mappings. The Matching Engine contains different libraries that supports many match algorithms and match strategies. The similarity results of individual matchers are maintained and aggregated within a similarity matrix per match task [1]. Match strategies implement workflows to deal with complex match tasks and enable a reuse of previous results and the decomposition of larger match tasks into smaller ones [3]. 1.1 State, purpose, general statement COMA and COMA++ have proven to be very effective for matching database and XML schemas [1, 4, 6]. The main reason for this test was to see the effectiveness of a generic matching tool for dealing with ontologies.

Lily results on SEALS platform for OAEI 2011
This paper presents the alignment results of Lily on SEALS platform for the ontology alignment contest OAEI 2011. Lily is an ontology matching system. In OAEI 2011, Lily submited the results for three matching tasks on the SEALS platform: benchmark, anatomy, conference. The specific techniques used by Lily are introduced. The matching results of Lily are also discussed.
متن کاملResults of the Ontology Alignment Evaluation Initiative 2006
We present the Ontology Alignment Evaluation Initiative 2006 campaign as well as its results. The OAEI campaign aims at comparing ontology matching systems on precisely defined test sets. OAEI-2006 built over previous campaigns by having 6 tracks followed by 10 participants. It shows clear improvements over previous results. The final and official results of the campaign are those published on ...
متن کاملTaxoMap in the OAEI 2007 Alignment Contest
This paper presents our first participation in the OAEI 2007 campaign. It describes an approach to align taxonomies which relies on terminological and structural techniques applied sequentially. We performed our method with various taxonomies using our prototype, TaxoMap. Previous experimental results were encouraging and demonstrate the relevance of this alignment approach. In this paper, we e...
متن کاملThe OAEI food task: An analysis of a thesaurus alignment task
This paper describes the “food task” of the Ontology Alignment Evaluation Initiative (OAEI) 2006 and 2007. The OAEI** is a comparative evaluation effort to measure the quality of automatic ontology-alignment systems. The food task focuses on the alignment of thesauri in the agricultural domain. It aims at providing a realistic task for ontology-alignment systems by which the relative performanc...
