On Matching Large Life Science Ontologies in Parallel [chapter]

Anika Gross, Michael Hartung, Toralf Kirsten, Erhard Rahm
2010 Lecture Notes in Computer Science  
Effective ontology matching, i.e. the computation of high quality mappings, typically entails the combined execution of several matchers to determine the similarity between ontology elements based on metadata  ...  The large size of existing ontologies and the application of complex match strategies for obtaining high quality mappings makes ontology matching a resource-and time-intensive process.  ...  This work is supported by the German Research Foundation (DFG), grant RA 497/18-1 ("Evolution of Ontologies and Mappings").  ...

PSOM2—partitioning-based scalable ontology matching using MapReduce

B Sathiya, T V Geetha, K Saruladha
2017 Sadhana (Bangalore)  
We have designed a new neighbour-based intra-similarity measure to increase the quality of the cluster set formation for the partition-based ontology matching process.  ...  One of the methods used to address this problem is the use of partition-based systems to reduce the matching space.  ...  When an entity of a partition shares a similar structure with one of its neighbours, their computed intra-ontology similarity will be large.  ...

Towards Large-Scale Schema and Ontology Matching [chapter]

Erhard Rahm
2010 Schema Matching and Mapping  
Large-scale matching needs especially be supported for XML schemas and different kinds of ontologies due to their increasing use and size, e.g. in e-business, web and life science applications.  ...  Unfortunately, correctly and efficiently matching large schemas and ontologies is very challenging and most previous match systems have only addressed small match tasks.  ...  Partition-based matching Partition-based matching is a divide-and-conquer strategy to first partition the input schemas / ontologies and then perform a partition-wise matching.  ...
