This paper reports the results of a preliminary experiment on the detection of semantic variants of terms in a French technical document. The general goal of our work is to help the structuration of terminologies. Two kinds of semantic variants can be found in traditional terminologies : strict synonymy links and fuzzier relations like see-also. We have designed three rules which exploit general dictionary information to infer synonymy relations between complex candidate terms. The results have been examined by a human terminologist. The expert has judged that half of the overall pairs of terms are relevant for the. | A step towards the detection of semantic variants of terms in technical documents Thierry Hamon and Adeline Nazarenko Cecile Gros Laboratoire d Informatique de Paris-Nord EDF-DER-IMA-TIEM-SOAD ưniversité Paris-Nord Avenue J-B Clement 93430 Villetaneuse FRANCE Abstract This paper reports the results of a preliminary experiment on the detection of semantic variants of terms in a French technical document. The general goal of our work is to help the structuration of terminologies. Two kinds of semantic variants can be found in traditional terminologies strict synonymy links and fuzzier relations like see-also. We have designed three rules which exploit general dictionary information to infer synonymy relations between complex candidate terms. The results have been examined by a human terminologist. The expert has judged that half of the overall pairs of terms are relevant for the semantic variation. He validated an important part of the detected links as synonymy. Moreover it appeared that numerous errors are due to few mis-interpreted links they could be eliminated by few exception rules. 1 Introduction Structuring a terminology The work presented here is a part of an industrial project of Technical Document Consultation System Gros et al. 1996 at the French electricity company EDF. The goal is to develop tools to help a terminologist in the construction of a structured terminology cf. figure 1 providing terms of a domain . simple or complex lexical units pointing out accurate concepts in a technical document Bourigault 1992 semantic links such as the see-also relation. This can be viewed as a two-step process. The candidate terms . lexical units which can 1 Avenue du General de Gaulle 92141 Clamart CEDEX FRANCE ceci le. gros @ der. edfgdf. fr be terms if a domain expert validates them are first automatically extracted from the technical document with a Terminology Extraction Software
