Embodiment Construction
[0030] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.
[0031] There are several methods for calculating the semantic similarity of words in the prior art: The first one: A statistical method based on word co-occurrence. This method mainly counts the frequency of words in sentences, such as TF-IDF algorithm, Jaccard Similarity Coefficient method and Metzler's improved method based on overlap. These methods are simple and efficient to implement, but completely ignore the lexical and semantic information of sentences. The second is an approach based on lexical and semantic information. This method considers the relevant elements of semantic information, but the construction is relatively complex, such as the calculation of semantic similarity based on ...
