This paper presents the alignment results of Lily for the ontology alignment contest OAEI 2009. Lily is an ontology mapping system, and it has four functions: generic ontology matching, large scale ontology matching, semantic ontology matching and mapping debugging. In OAEI 2009, Lily submited the results for four alignment tasks: benchmark, anatomy,(More)
This paper presents the alignment results of Lily for the ontology alignment contest OAEI 2008. Lily is an ontology mapping system, and it has four main features: generic ontology matching, large scale ontology matching, semantic ontology matching and mapping debugging. In the past year, Lily has been improved greatly for both function and performance. In(More)
Multi-ontologies environments are common in semantic web and knowledge representation fields. How to represent the complex relationships between ontologies is a key problem of the multi-ontologies-based applications. For the purpose of solving the problem, this paper proposed the theory of bridge ontology to represent twelve kinds of relationships between(More)
Most existing ontology matching methods are based on the linguistic information. However, some ontologies have not sufficient or regular linguistic information such as natural words and comments, so the linguistic-based methods can not work. Structure-based methods are more practical for this situation. Similarity propagation is a feasible idea to realize(More)
Web ontologies are often too large to be used in a single application. The solution is to extract sub-ontology from large-scale ontology. An application may require several large-scale ontologies in different domains. Current approaches mainly focus on extraction in single ontology; it needs to integrate the ontologies and then extract sub-ontology from the(More)
