  • Patent number: 8341012
    Abstract: A working skill estimating program is provided for estimating working skills of each agent in the state of separating a disturbance factor from response records (incidents). A large category classifier is supplied with the incidents within a predetermined time and classifies the incidents according to classification rules, for creating the topic-classified incidents. A small category generator collects the analogous incidents for each task type of the topic-classified incidents and generates a small category. A disturbance distinguisher distinguishes if the incidents belonging to each small category are common response records that appear regularly over time or disturbances whose frequency exhibits a significant time dependency. Then, a skill estimator estimates the working skills of each agent for each task type by using only common incidents determined as the common information.
