[0158] 1. In order to verify the effect of the word similarity calculation method, the present invention carries out the experiment of similarity calculation with several groups of commonly used words. In the experiment, two word similarity calculation methods are used for verification, which are the method proposed by the present invention and an existing method.
[0159] The present invention assumes that the two methods have different algorithms when calculating the sememe set, that is, the method proposed by the present invention is the same as the existing method that only takes the maximum value, and other steps are the same. Table 4 shows the similarity calculation results of some words.

[0162] 2. Performance test:
[0163] In the experiment, 6000 nouns were tested, and the consistency rate was compared between the automatically recognized semantic class results and the manually proofreaded semantic classes in the CSD dictionary. The results a...

[0167] 1. In order to verify the application of word similarity in the question answering system, the present invention has established a knowledge base answering system with nearly 3000 pieces of data, involving various fields. Examples include books, movies, people and places of interest.
[0168] For all questions, and all answers in the knowledge base question answering system, word division is realized based on the software ICTCLAS (http: / / www.ICtcas.org / ). After that, stop words and symbols are removed.
[0169] Specific names of people, places, and time that do not appear in HowNet are replaced with abstract words such as "person's name", "place name", and "time" respectively. For example, replace "Yang Feiyu" with "person's name"; replace "Mugecuo" with "place name"; replace "2018 / 1 / 30" with "time".
[0170] Remove repetitions.
