Abstract
Providing sentiment classification of out of domain data are disclosed herein. In some aspects, a source domain having a trained classifier is matched to a target domain having a target classifier. The trained classifier may include identifiers that may be used to predict the sentiment of opinion data for the source domain. The target classifier may use the identifiers of the trained classifier to determine the sentiment of opinion data for the target domain.
Claims20
A method, comprising:
- collecting textual data of a target domain;
- categorizing, by a target classifier associated with the target domain, the textual data according to sentiment using identifiers previously imported to the target classifier from a trained classifier associated with a source domain;
- and
- sending data for display in a user interface to present a summary of results that are based at least in part on the categorizing the textual data.

A system comprising:
- one or more processors;
- memory storing computer-executable instructions that, when executed on the one or more processors, perform acts comprising:
- collecting textual data of a target domain;
- categorizing, by a target classifier associated with the target domain, the textual data according to sentiment using identifiers previously imported to the target classifier from a trained classifier associated with a source domain;
- and
- sending data for display in a user interface to present a summary of results that are based at least in part on the categorizing the textual data.

- categorizing, by a target classifier associated with the target domain, the opinion data according to sentiment using identifiers previously imported to the target classifier from a trained classifier associated with a source domain;
- and
- sending data for display in a user interface to present a summary of results that are based at least in part on the categorizing the opinion data, the summary of results comprising a total number of instances of the opinion data, and a percentage of the total number of instances of the opinion data that fall into one or more sentiment categories according to the categorizing the opinion data.
