We have developed an information retrieval system for telephone dialogue in a load dispatch center. In load dispatching operations, the needs for recording and information retrieval of a telephone dialogue are high. The proposed system gives a solution for the task and realizes an information retrieval function with any keywords. The effectiveness of the system is verified by telephone dialogue transcription and information retrieval experiments. With 30 telephone dialogues in a load dispatch center, we obtain 59.5% in average word correct and 44.4% in average word accuracy. In the information retrieval experiment, with 20 keywords, we obtain 87.3% in average precision and 67.2% in average recall. © 2007 Wiley Periodicals, Inc.
