In this article we demonstrate the use of the tool OntoLP in the ontology construction process in an experiment in the health care area. Specifically, terms based on a corpus in the pediatrics area are extracted. We compare the result obtained by the tool with the reference results of a list of terms obtained manually. In this comparison, bigrams and trigrams obtained through different methods are analyzed. We conclude the work by observing the advantages of processing by including complex

Keywords processing of natural language; ontologies; construction of ontologies for the health care area; semi-automatic extraction of terms This Appendix presents the 70 first terms identified with each method (bigrams) with exclusion of terms. The extracted terms which appear in the reference have been highlighted.
