Abstract
An information processing apparatus includes a receiving unit, a determining unit, a first assigning unit, an extracting unit, a second assigning unit, a modeling unit, and an output unit. The receiving unit receives a target character string. The determining unit determines whether a sentiment character string is included in the received character string. A first assigning unit assigns a label corresponding to a sentiment character string to the character string when the sentiment character string is included, and assigns plural labels to the character string when no sentiment character string is included. The extracting unit extracts a word from the character string. The second assigning unit assigns to the extracted word a label which has been assigned to the character string that includes the word. The modeling unit performs supervised topic modeling for the character string. The output unit outputs a result of a process by the modeling unit.
