Embodiment Construction
[0041] In the present embodiment, a kind of emotion classification method of the Bilstm model that fuses word vector and aspect vector, part-of-speech vector, and adds Attention mechanism is to carry out as follows:
[0042] Step 1. Obtain all short texts in the comment data and use them as a corpus, perform preprocessing operations such as classification, cleaning, and word segmentation on any short text in the corpus, and obtain the word segmentation set of the corresponding short text, which is recorded as t=(t 1 ,t 2 ,...,t i ,...,t k ), t i Represents the i-th word, i∈[1,k], k represents the total number of words in the short text;
[0043] Step 2, pair word vector set t=(t 1 ,t 2 ,...,t i ,...,t k ) for part-of-speech recognition, and obtain the part-of-speech representation vector set p″’=(p″’ 1 ,p″' 2 ,...,p″′ i ,...,p″′ k ), p″' i represents the i-th word t i the corresponding part of speech;
[0044] Step 3. Perform preprocessing operations on all short...
