Abstract

A new information in a language and relating to a subject matter domain is parsed into a constituent set of complete grammatical constructs. In a subset of the complete grammatical constructs, a set of linguistic styles of the language is identified according to a subset of a set of word-style associations related to the language and independent of the subject matter domain. A first weight is assigned to a first linguistic style and a second weight to a second linguistic style from the set of linguistic styles. A first intention information is mapped to the first style using a first style-intention rule, and a second intention information to the second style using a second style-intention rule. A complete grammatical construct in the subset is tagged with the first intention information responsive to a weight associated with the first intention information exceeding an intention selection threshold.

Claims

1. A method for intention detection in information, the method comprising:

parsing a new information into a constituent set of complete grammatical constructs, the new information being in a language and relating to a subject matter domain;

identifying, in a subset of the complete grammatical constructs, a set of linguistic styles of the language according to a subset of a set of word-style associations related to the language and independent of the subject matter domain;

assigning a first weight to a first linguistic style and a second weight to a second linguistic style, the set of linguistic styles including the first linguistic style and the second linguistic style;

mapping a first intention information to the first style using a first style-intention rule, and a second intention information to the second style using a second style-intention rule; and

tagging a complete grammatical construct in the subset with the first intention information responsive to a weight associated with the first intention information exceeding an intention selection threshold.

2. The method of claim 1, further comprising:

determining, using an encoded structure, that the subset of complete grammatical constructs is related to a section of the encoded structure, wherein the new information conforms to the encoded structure;

determining, using the encoded structure, a second set of linguistic styles corresponding to the section of the encoded structure;

concluding that the first linguistic style and the second linguistic style are also members of the second set of linguistic styles, wherein the assigning the first second and third weights is responsive to the concluding.

3. The method of claim 2, further comprising:

evaluating, using the encoded structure, that the first linguistic style is more likely to be present in the section than the second linguistic style, wherein the first weight is greater than the second weight responsive to the evaluating.

4. The method of claim 1, further comprising:

assigning a third weight to a third linguistic style, the set of linguistic styles including the third linguistic style; and

omitting the third linguistic style from the mapping responsive to the third weight being below a style selection threshold.

5. The method of claim 1, further comprising:

constructing, using second set of linguistic styles of the language, and using a taxonomy of intentions present in a training information relating to the subject matter domain, a set of style-intention rules, the set of style-intention rules including the style-intention rule, the style-intention rule relating a selected intention from the taxonomy of intentions with a selected linguistic style in the set of linguistic styles to indicate that the selected intention is present where the selected linguistic style appears in any information related to the subject matter domain.

6. The method of claim 1, further comprising:

constructing, using a training information, a structure, wherein the training information conforms to the structure;

encoding the structure, to form the encoded structure, by associating a third linguistic style that is present in a portion of the training information with a section of the structure; and

assigning a third weight to the third linguistic style in the section.

7. The method of claim 1, further comprising:

constructing, using a lexicon of the language, the set of word-style associations, wherein a word in a word-style association is used in the language to convey the corresponding style in the word-style association.

8. The method of claim 1, further comprising:

adjusting, according to a third style-intention rule, the first weight to a third weight, wherein the first intention information is associated with the third weight.

9. The method of claim 1, further comprising:

omitting tagging the complete grammatical construct in the subset with the second intention information responsive to a weight associated with the second intention information not exceeding the intention selection threshold.

10. The method of claim 1, wherein the language is English, and a complete grammatical construct in the set of complete grammatical constructs is a sentence according to English grammar.

11. A computer usable program product comprising a computer readable storage device including computer usable code for intention detection in information, the computer usable code comprising:

computer usable code for parsing a new information into a constituent set of complete grammatical constructs, the new information being in a language and relating to a subject matter domain;

computer usable code for tagging a complete grammatical construct in the subset with the first intention information responsive to a weight associated with the first intention information exceeding an intention selection threshold.

12. The computer usable program product of claim 11, further comprising:
