Abstract:
The problem of partial parsing is considered in this paper. New heuristics are proposed to reduce the quantity of chunks falsely exposed at the first step of analysis. A very large influence is rendered by the phenomena of homonymy and polysemy on detection of chunks in russian. Falsely exposed chunks are treated as ones which were found out by a partial parser, but are not actually correct. The method of search of chunks with the use of these heuristics got the name “Right-chunk 4”. The formal task statement is carried out. Computer realization of method of search of chunks is executed as software “Chunk-creator 4”. The estimation of quality is conducted.
