Extraction Model
Extraction Model:A nswer sentence selection Due to increasing complexity in question answering, deep learning has become a popular trend in solving difficult problems. Approaches Word Count: counts the number of non-stopwords in the question that also occur in the answer sentence. Weighted Word Count: re-weights the counts by the IDF values of the question words. LCLR :makes use of rich lexical semantic features, including word/lemma matching, WordNet and vector-space lexical semantic models. Convolutional Neural Network Recurrent Neural Network
