According to linguists, there is an inevitable gap between a syntax and semantics, due to the fundamental principle of arbitrariness of phonemes used. To put it simple, any sequence of sounds could be associated with any meaning (given a distinct semantics). Morphemes however, while in some cases could be used as a direct pointers to the meaning, nevertheless require one or even several contexts to be interpreted correctly. TL;DR - there is no way to get proper semantics without mastering appropriate contexts (domain knowledge) from mere syntax in principle. One would get certain word patterns, but not the corresponding deep structure (the intended meaning). Summarization would be arbitrary. Try to summarize the sermon on the mount.
