We claim that it is necessary for semantic representations of technical papers to describe a word's meaning from various points of view and emphasize the semantic aspect of words. In this paper, we describe semantic representations of technical papers based on Pustejovsky's GENERATIVE LEXICON(GL). Our focus is on technical papers concerned with metallurgy because this research is carried out in cooperation with an expert in metal engineering. Our purpose for making semantic representations is twofold : (1) to detect differences and inconsistencies among papers by applying appropriate mechanisms; and (2) to integrate the content of a new paper into the content of an existing one. The semantic representations of technical papers based on the generative lexicon are modified so that they match the characteristics ofthe papers. In addition, we propose operations worked effectively on the semantic representation. Modifying some rules included the semantic representation for each paper makes it possible to analyze the semantic differences and similarities among the papers. The semantic representation is implemented using an object-oriented database management system on MATISSE.
