    Word Vector Representation

    • Based on KANKAN AI owned word vector and deep learning, it can complete the word vector representation quickly, in which the words or phrases from the vocabulary are mapped to the real number vector. The methods for generating such mapping include neural network, dimensional reduction of word mutualistic matrix, probability model, interpretable knowledge base methods, and explicit representations of terms and background of the word.
    • When used as a low-level input representation, word and phrase embedding have been proven to be able to improve the performance of NLP tasks, such as grammar analysis and emotion analysis.
