... parser, semantic analyzer, and target sentence generator. Introducing a full-fledged semantic analyzer con- flicts with avoiding increases in processing time and memory use. To resolve this ... main role is to separate parsing from semantic analysis, i.e., to make these processes independent of each other. In LTNG, parsing includes no semantic analysis. Any ambiguities in an i...
