چکیده
In this paper, we described our CCLQA system and the evaluation results for the C-C task at NTCIR-8 ACLIA. The system consists of a Question Analysis module, IR module and Answer Extraction module. The Question Analysis module was developed for NTCIR-7 CCLQA, which is based on the Question pattern library and HowNet. The IR module was developed for NTCIR-8 IR4QA task, and the results of KECIR-CS-CS-01-T were used as question related documents. For answer extraction, a Surface-Based Multi-Strategy approach was used. It deals retrieval results with different Strategies. The evaluation results show that our system achieves 0.3450 average F-score (beta = 3).
