Our RICT team tackled segmentation and classification subtasks in NTCIR-14 QA Lab-PoliInfo. As our technical characteristic in segmentation task, we regard segments as retrieval objects, and utilize cue-phase-based methods including a nobel semi-supervised learning method to detect segment boundary. Here we have presented 5 methods for formal run. As to classification task, we train our supervised learning model by all utterances without topic effects and utilize outlier detection technologies to alleviate the imbalance training data problem. Here we have submitted 7 runs for formal run. Since evaluation results show that our approach achieves higher scores than average, the main contribution for classification we made is providing a feasible system to deal with a small number of imbalance training data problem especially in the regional assembly minutes. Meanwhile, we also made contribution for segmentation to grasp distinguishing features of regional assembly minutes by our efficient method.
