Terminology Extraction from the web

This paper presents the results of a study on textual resources in the field of Human Language Technology (HLT). A statistical representation of the most significant terms in HLT and other interrelated disciplines associates old and new words, highlighting the terminological changes that have taken place in the course of time. Aim of our study is to contribute to the creation of language resources for the extraction of documentation coming from the Web in order to help preventing the disappearance of documents containing HLT words that have undergone rapid development over the last decades. This paper is organised as follows: after a general introduction to our work, section 2 provides a historical overview of HLT; sections 3 and 4 offer an account of the most relevant terms used by specialists in different periods, and those indicative of the changes that have taken place; section 5 describes the methodology we have used and also contains information on our database and a graphical representation of the data. Finally, the conclusions stress the need to integrate pre-existing or obsolete words and expressions, creating HLT synonym relations.
