The core of the system is constituted by the analyzer that includes parallel processing of syntactic and semantic knowledge. It is argued that this feature (together with the new macro and micro-analysis technique which is only shortly mentioned in this paper) allowed the system to reach a good linguistic coverage, still ensuring an acceptable degree of effici ency. After the basic architecture and operation of PARNAX have been described, attention is focused on the parallel syn tactic/semantic analyzer which is illustrated in detail. The advantages obtained through parallelism are also shortly discussed. Examples of PARNAX operation are presented. References to related works are mentioned, and directions for future research are outlined. 1.
