Ontology learning from text: Evaluation of learned ontologies
Ana Bertha Rios-Alvarado, Iván López-Arévalo · 2013
Ontologies provide a structural organizational knowledge, they support the exchange and sharing of information. Moreover, one of the main benefits of using ontologies is the ability to infer new knowledge that allows the development of more realistic applications such as semantic search, automated reasoning, classification, query answering, among others. The need for overcoming the bottleneck, given in the knowledge acquisition by the manual construction of ontologies, has motivated studies on semi-automatic and automatic methods to build ontologies. One of the main sources of knowledge created by humans is given by text resources. The analysis and extraction of the elements of an ontology from texts is a very hard task. In particular, the acquisition of more expressive elements is our main goal. In this report we focus on present the experiments on four corpora and the evaluation made of the identified axiomatic relations (subClassOf, disjointWith, and equivalentClass). Also, we include the results compared with two related works showing prominent results. This report of activities corresponds to the fourth year of doctoral studies.
