To eliminate the ambiguity on parsing coordinate structure, the sentences are evaluated to low, if they have problems in either syntactic or semantic process. The major part of the minus point in parsing coordination structure is the degree of morpheme similarity. Finally, we demonstrate our work by using the parser system, JUST, which we developed in respect to the coordinate structure. Such senses do not match the actual situation. Most words with a high degree of polysemy are verbs.
Words representing the body are highly polysemic from the view-point of more detailed categories.
Except for words in Category 1.5, derived meaning tends to remain within the original semantic category. On the other hand, polysemic meaning derived from words in Category 1.5 are generally assigned to other categories. The latter derivations are based on a word form, position, function, and essential properties. Category 1.5 derivations are extremely diverse. The automatic segmentation methods adopted as algorithms for the program are divieded into two parts.
