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.

One of a plurality of prepared given expressions is displayed on a screen. After the given expression is presented to the user, the position of a face feature point is detected from a face image of the user taken by a camera cartridge. Based on the detected position of the face feature point, the user's expression in the face image is expressed in accordance with the evaluation criteria corresponding to the given expression, and an image representing the evaluation result is displayed on the screen. Thus, the user can effectively train the mimetic muscles.

In systems which support oral entry of Personal Identification Number (PIN) values in order to establish access to user accounts, a user is prompted to enter the PIN value for a particular account. The entered PIN value is analyzed by a speech recognition engine to extract both a multi-digit number and the user's expression of that number. The extracted multi-digit number is compared to a multi-digit number stored in a user record associated with the account. If the user previously specified that expression matching is required, the extracted expression of the multi-digit number is compared to a preferred expression stored in the user record. Matches must be found for both the numbers and the form in which those numbers are expressed in order for the user to be authenticated. The user may elect to dispense with the expression matching requirement.
