User modification of generative model for determining topics and sentiments

摘要

A generative model is used to develop at least one topic model and at least one sentiment model for a body of text. The at least one topic model is displayed such that, in response, a user may provide user input indicating modifications to the at least one topic model. Based on the received user input, the generative model is used to provide at least one updated topic model and at least one updated sentiment model based on the user input. Thereafter, the at least one updated topic model may again be displayed in order to solicit further user input, which further input is then used to once again update the models. The at least one updated topic model and the at least one updated sentiment model may be employed to analyze target text in order to identify topics and associated sentiments therein.

主权项

1. A method comprising:
providing, by a processing device implementing a generative model for determining topics and sentiments within text, at least one topic model and at least one sentiment model; providing, by the processing device and for display, at least a portion of the at least one topic model; receiving, by the processing device via a user input device operatively connected to the processing device, user input data,
the user input data indicating modification of the at least one topic model, andthe user input data indicating a new feature and associated feature probability corresponding to a topic; and providing, by the processing device via the generative model, at least one updated topic model and at least one updated sentiment model based at least in part upon the user input data.
