In this paper, we present a method for the semantic tagging of word chunks ex- tracted from a written transcription of con- versations. This work is part of an ongo- ing project for an information extraction system in the field of maritime Search And Rescue (SAR). Our purpose is to auto- matically annotate parts of texts with con- cepts from a SAR ontology. Our approach combines two knowledge sources a SAR ontology and the Wordsmyth dictionary- thesaurus, and it uses a similarity measure for the classification. Evaluation is carried out by comparing the output of the system with key answers of predefined extraction templates.
