Falcon-AO is a tool that aligns ontologies using two matching techniques: 1. LMO performs linguistic matching using techniques like string similarity, document similarity, and term weighting in a vector space model. 2. GMO performs graph matching using a bipartite graph model and similarity accumulation. The tool was tested on a number of ontology matching tasks and achieved high accuracy, recall, and precision on tasks with high linguistic comparability, demonstrating its effectiveness at ontology alignment.
