... Reducing T -tag options. Some procedures are incorporated into T -tag assignment which serve to reduce the explosive combinatorial possibilities of a long partial parse with several T -tag options. ... subsequent modification to the system resulted in over 96 per cent of word tags being correctly assigned automatically. The remaining 3 to ~ per cent were corrected by huma...
