Abstract

A typical sentence having a specific typical characteristic in the sentence is divided. A division target typical sentence is divided on the basis of a small clause definition. The sentence is divided where positions suitable for dividing the typical sentence based on the structure are expressed by a user. A small clause string including small clauses that serve as independent sentences is created after the division. The small clause string is compared to the structure patterns, and a structure pattern that is determined to match the small clause string is selected as a result of the typical sentence division.

Claims

1. A computer-readable medium having a sentence dividing program stored thereon, the sentence dividing program allowing a computer to execute a sentence dividing method for dividing a typical sentence having a specific typical characteristic in a structure of the sentence, the method comprising:

dividing, under a circumstance where positions suitable for dividing the typical sentence based on the structure are expressed by a user using property information of the sentence and are previously stored as a small clause definition in a first storage unit, a division target typical sentence on the basis of the small clause definition stored in the first storage unit, and of creating a small clause string including small clauses that serve as independent sentences after the division;

comparing, under a circumstance where structures suitable for the typical sentence are expressed by the user as combinations with each small clause definition and are previously stored as structure patterns in a second storage unit, the small clause string with the structure patterns stored in the second storage unit; and

selecting, as a division result of the typical sentence, a structure pattern that is determined to match the small clause string.

2. The computer-readable medium having the sentence dividing program stored thereon according to claim 1, the method further comprising:

evaluating, when a plurality of structure patterns are determined to match the small clause string, a degree of matching of the small clause string and each of the plurality of structure patterns; and

sorting, according to a result of the evaluation, the order of the plurality of structure patterns that are determined to match the small clause string.

3. The computer-readable medium having the sentence dividing program stored thereon according to claim 1, the method further comprising:

analyzing, regarding the small clause string, dependency between the small clauses constituting the small clause string; and

eliminating, according to a result of the analysis, a small clause that modifies a skeletal small clause that serves as a skeleton in the structure of the typical sentence to transform the small clause string into a skeletal small clause string including only skeletal small clauses, wherein

the comparing includes comparing the skeletal small clause string with the structure patterns.

4. A sentence dividing apparatus for dividing a typical sentence having a specific typical characteristic in a structure of the sentence, the apparatus comprising:

a small clause definition storage previously storing a small clause definition, in which positions suitable for dividing the typical sentence based on the structure are expressed by a user using property information of the sentence;

the structure pattern storage previously storing structure patterns, in which structures suitable for the typical sentence are expressed as combinations with each small clause definition;

a small clause string creator for dividing a division target typical sentence on the basis of the small clause definition stored in the small clause definition storage, and for creating a small clause string including small clauses that serve as independent sentences after the division;

a comparator for comparing the small clause string with the structure patterns stored in the structure pattern storage; and

a selector for selecting, as a division result of the typical sentence, a structure pattern that is determined to match the small clause string by the comparator.

5. A sentence dividing method for dividing a typical sentence having a specific typical characteristic in a structure of the sentence, the method comprising:

dividing, under a circumstance where positions suitable for dividing the typical sentence based on the structure are expressed by a user using property information of the sentence and are previously stored as a small clause definition in a first storage unit, a division target typical sentence on the basis of the small clause definition stored in the first storage unit, and of creating a small clause string including small clauses that serve as independent sentences after the division;

comparing, under a circumstance where structures suitable for the typical sentence are expressed by the user as combinations with each small clause definition and are previously stored as structure patterns in a second storage unit, the small clause string with the structure patterns stored in the second storage unit; and

selecting, as a division result of the typical sentence, a structure pattern that is determined to match the small clause string.
