Abstract

An authoring assistant includes a parser which automatically identifies opinion expressions in input text. The text may include an author'"'"'s review of an item, such as a product or service. A computer-implemented opinion review component generates an analysis of the text, which is based on the identified opinion expressions. The opinion review component computes an effective opinion of the text as a function of a measure of polarity associated with the identified opinion expressions. A representation generator generates a representation of the analysis for display on an associated user interface. The representation of the analysis includes a representation of the effective opinion. In the case of a review, the authoring assistant may allow the author to modify the review to reduce incoherence with a rating of the item.

Claims

1. An authoring assistant comprising:

a parser which identifies opinion expressions in an input text;

an opinion review component which generates an analysis of the text based on the identified opinion expressions, the opinion review component computing an effective opinion of the text as a function of a measure of polarity associated with the identified opinion expressions;

a representation generator which generates a representation of the analysis for display on an associated user interface, the representation of the analysis including a representation of the effective opinion; and

a processor which implements the opinion review component and representation generator.

2. The authoring assistant of claim 1, wherein the opinion review component comprises a comparator component which compares the effective opinion with a rating associated with the text to determine whether the text and the rating are coherent.

3. The authoring assistant of claim 2, further comprising a warning component which outputs a warning when the effective opinion and rating are incoherent.

4. The authoring assistant of claim 2, wherein the text and rating are extracted from an author'"'"'s review of an item.

5. The authoring assistant of claim 2, further comprising a synonym generator for identifying synonyms of terms of identified opinion expressions, the representation generator displaying at least one synonym of one of the terms in an identified opinion expression when the effective opinion and the rating associated with the text are incoherent.

6. The authoring assistant of claim 1, further comprising a display device for displaying the representation.

7. The authoring assistant of claim 1, wherein in the representation, each of the identified opinion expressions is identified.

8. The authoring assistant of claim 1, further comprising a user interface which displays the representation and provides for an author to modify the text after the representation has been displayed.

9. The authoring assistant of claim 1, further comprising memory which stores a polar vocabulary comprising a set of polar terms, each polar term in the polar vocabulary being associated with a polarity measure, the measure of polarity associated with at least some of the identified opinion expressions being based on the polarity measure of one of the polar terms which is present in the opinion expression.

10. The authoring assistant of claim 9, wherein the polarity measure is selected from a negative polarity and a positive polarity.

11. The authoring assistant of claim 1, wherein in the representation, the effective opinion is graphically represented.

12. The authoring assistant of claim 1, wherein at least some of the opinion expressions identifiable by the parser include a semantic relation between a first text element and a second text element, wherein at least one of the text elements is associated with a respective polarity measure.

13. A method for assisting an author, comprising:

parsing an input text to identify opinion expressions in the input text;

with a processor, generating an analysis of the text, based on the identified opinion expressions including computing an effective opinion of the text as a function of a measure of polarity associated with each of the identified opinion expressions; and

generating a representation of the analysis for display on a user interface, the representation of the analysis including a representation of the effective opinion.

14. The method of claim 13, further comprising displaying the representation of the user interface and providing for an author to modify the text after the representation has been displayed.

15. The method of claim 13, wherein the generation of the analysis comprises comparing the effective opinion with a rating associated with the text to determine whether the text and the rating are coherent.

16. The method of claim 15, further comprising outputting a warning when the effective opinion and rating are incoherent.

17. The method of claim 13, wherein the text and rating are extracted from an author'"'"'s review of an item.

18. The method of claim 13, further comprising providing for identifying synonyms of terms of identified opinion expressions and for displaying at least one synonym of one of the terms in an identified opinion expression.

19. The method of claim 13, wherein in the representation, each of the identified opinion expressions is identified.

20. The method of claim 13, further comprising storing a polar vocabulary comprising a set of polar terms in memory, each polar term in the polar vocabulary being associated with a polarity measure, the measure of polarity associated with at least some of the identified opinion expressions being based on the polarity measure of one of the polar terms which is present in the opinion expression.

21. The method of claim 20, further comprising acquiring a set of polar adjectival terms from a corpus of reviews, each of the reviews in the corpus including text and an associated rating provided by the author of the review and incorporating the polar adjectives into the polar vocabulary.

22. The method of claim 21, wherein the acquiring of the set of polar adjectival terms comprises:

extracting textual content from reviews in the corpus of reviews;

identifying a set of frequent nouns from the textual content of the reviews,

extracting adjectival terms from the textual content of the reviews, each adjectival term being associated in the textual content with one of the frequent nouns; and

generating the set of polar adjectival terms including at least some of the extracted adjectival terms, a polarity measure being associated with each adjectival term in the set which is based on the ratings of the reviews from which the adjectival term was extracted.

23. The method of claim 20, wherein the polarity measure associated with polar terms in the polar vocabulary is selected from a negative polarity and a positive polarity.

24. The method of claim 20, wherein when an opinion expression is identified as a negated opinion expression, the polarity measure of the polar term is modified.

25. The method of claim 13, wherein in the representation, the effective opinion is graphically represented.

26. The method of claim 13, wherein the extraction of the opinion expressions includes applying parser rules for identifying a semantic relation between a first text element and a second text element, wherein at least one of the text elements is associated with a polarity measure upon which the measure of polarity of the opinion expression is based.

27. A system for performing the method of claim 13 comprising memory which stores instructions for performing the method and a processor in communication with the memory for executing the instructions.

28. A computer program product comprising a non-transitory recording medium encoding instructions, which when executed on a computer causes the computer to perform the method of claim 13.

29. A method comprising:

extracting textual content from reviews in a corpus of reviews, each of the reviews including a rating;

identifying a set of frequent nouns from the textual content of the reviews;

extracting adjectival terms from the textual content of the reviews, each adjectival term being associated in the textual content with one of the frequent nouns;

generating a polar vocabulary which includes at least some of the extracted adjectival terms, a measure of polarity being associated with each adjectival term in the polar vocabulary which is based on the ratings of the reviews from which the adjectival term was extracted;

providing for parsing an input text to identify opinion expressions in the input text;

providing for generating an analysis of the text, based on the identified opinion expressions including computing an effective opinion of the text as a function of a measure of polarity associated with each of the identified opinion expressions which is based on the measure of polarity associated with respective ones of the adjectival terms in respective ones of the opinion expressions; and

generating a representation of the analysis for display on a user interface, the representation of the analysis including a representation of the effective opinion.
