- Abstract:
- Emotional question answering analyses opinions, polarity, and other factors related to sentiment analysis. Evaluations are complex compared to those for responses to factual questions. A great number of emotional questions were collected from the internet, and a chunk conditional random field (CRF) model and heuristic rules were applied to classify them into five types based on the emotional features of the questions. This classification method is different from the factual question classification method, which is mainly based on interrogative words, as it has to take the opinions and responses from users into account. Combined with polarity and recognition results from Chunk-CRF, different answers were extracted according to different question types. The experiment shows that this evaluation system for emotional question answering is effective and efficient.
