RiMOM2013 results for OAEI 2013

This paper presents the results of RiMOM2013 in the Ontology Alignment Evaluation Initiative (OAEI) 2013. We participated in three tracks of the tasks: Benchmark, IM@OAEI2013 , and Multifarm. We first describe the basic framework of our matching System (RiMOM2013); then we describe the alignment process and alignment strategies of RiMOM2013, and then we present specific techniques used for different tracks. At last we give some comments on our results and discuss some future work on RiMOM2013. 1 Presentation of the system Recently, ontology is increasingly seen as an apocalyptic factor for enabling interoperability between heterogeneous systems and Semantic Web applications. Ontology Aligning is required for combining distributed and motley ontologies. Developing ontology alignment systems has become an essential issue of recent ontology research. RiMOM2013 is named after RiMOM(RiskMinimization based OntologyMapping) which is a multi-strategy ontology alignment system and was firstly developed in 2007 [1][2]. RiMOM implements several different matching strategies that have been defined based on different ontological information. For different ontology mapping tasks, RiMOM can automatically select and combine multiple strategies to generate accurate alignment results. RiMOM has evolved all the time since 2007, and RiMOM2013 is developed based on RiMOM and has several new characteristics that will be described in following subsections. 1.1 State, purpose, general statement As shown in Fig. 1, the whole system is consists of three layers: User Interface layer, Control layer and Component layer. In the User Interface layer, RiMOM2013 provides an interface to allow customizing the matching procedure: including selecting preferred components, setting the parameters for the system, choosing to use translator tool or not. In semi-automatic ontology matching, the task layer stores parameters of the alignment tasks, and controls the execution process of components in the component layer. In component layer, we define six groups of executable components, including preprocessor, matcher, aggregator, evaluator, postprocessor and other utilities. In each group, there are several instantiated components. For a certain alignment task, user can select appropriate components and execute them in desired sequence.
