The present communication relates to the activities I am carrying out as part of the "Translation Project of the Babylonian Talmud" and the PRIN 2017 project "Religious Diversity". After a brief introduction relating to the activities carried out by the research group involved in these two projects, the areas in which I am collaborating will be summarized, namely: i) definition of a model for the representation of knowledge conveyed by texts in relation to information of various kinds; ii) implementation of lexical functions in the context of terminological modeling; iii) analysis and study of the PAROLE-SIMPLE-CLIPS (PSC) resource, a computational lexicon for Italian, aimed at updating and using it; iv) elaboration of a methodology for the study of the lexicon of the religious diversity from a computational point of view. The first point will focus on the definition of a model based on the concept of "diasystem" and on its operational use in the computational context; the second and third points will focus on resources and, in particular, on the use of lexical functions in a termino-ontological resource and on the recovery of a complex and stratified resource such as PSC in the context of tasks such as the full-text search. The fourth and last point consists in a synthesis between the use of the model and the use of lexicographic resources, through a methodology of comparative study starting from the text as a datum and a source of information to be extracted.
