Methods and apparatus for sentiment analysis
Analysis is enabled, of a corpus of statements (such as those from social media), according to each statement's expression of sentiment about some kind of object. Object-specific corpuses are identified, where each object-specific corpus contains statements that refer to a same object. For each statement of an object-specific corpus, the polarity and intensity of sentiment expressed is determined. Net polarity and intensity measures are determined for each object-specific corpus and utilized to graph the corpus in a two-dimensional space. The area of the graphical symbol, representative of an object-specific corpus, can be proportional to the number (absolute or relative) of statements of the object-specific corpus. Brands can be compared, with each brand represented by an object-specific corpus. A single brand can have shown, relative to a temporal dimension, the net polarity, net intensity, or volume of its statements. Net polarity is shown to have a strong correlation with survey-based techniques.

Negative expression identifying and encouraging system
InactiveCN106446753AGood groomingImprove the quality of workAcquiring/recognising facial featuresImaging processingPre treatment
The invention provides a negative expression identifying and encouraging system which belongs to the technical field of image processing and artificial intelligence. The technical schemes of the invention are as follows. A computer camera captures and analyzes a user's expressions to help remove negative emotions. A system firstly pre-acquires the basic expression samples of the user and uses them as a characteristic template. A video is initiated in a fixed time to collect the facial images of the user in the fixed time. Then, the facial images experience pre-treatment, identification and analysis. The facial images that are acquired in real time are matched with the expression characteristic template for the changes in key characteristic parts in terms of European distance difference, geometrical shape, curvature and angle. The similarity is compared to determine whether the user's expressions are angry, anxious, tired or happy ones. A statistic shape and other statistical methods are used to analyze and determine whether the user's mood in a certain period is negative or not and the system reminds the friends of the user of the negative mood of the user; and after the reminding when the user's expressions become good again, rewards and encouragement are given accordingly. With the system, the working mood of an employee can be improved; the working efficiency is raised; and the economic gains of an enterprise go up as well.
