Abstract ⎯ A module for enconversion of NL texts into Universal networking Language (UNL) graphs is considered. This module is designed for the system of multilingual communication in the Internet that is being developed by research centers of about 15 countries under the aegis of UN. The enconversion of NL texts into UNL is carried out by means of a multi-functional linguistic processor ETAP-3, developed in the Computational linguistics laboratory of the Institute for Information Transmission Problems of the Russian Academy of Sciences. One of the major problems in the automatic text analysis is high degree of ambiguity of linguistic units. The resolution of this ambiguity (morphological, syntactic, lexical, translational) is partly ensured by the linguistic knowledge base of ETAP-3, but complete algorithmic solution of this problem is unfeasible. We describe an interactive system that helps resolve difficult cases of linguistic ambiguity by means of a dialogue with the human. Index Terms ⎯ interactive disambiguation, knowledge representation, UNL system, parsing. 1. INTRODUCTORY REMARKS ETAP-3 is a multipurpose NLP environment that was conceived in the 1980s and has been worked out in the
