Abrégé
(EN)
The invention relates to the technical field of semantic parsing, in particular to a statement rationality judgment method and device based on semantic parsing and computer equipment. The method comprises the following steps: establishing an ngram model, and obtaining a to-be-judged statement input by a user; performing word segmentation processing on the to-be-judged statement to obtain a plurality of segmented words corresponding to the to-be-judged statement; loading a plurality of segmented words corresponding to the to-be-judged statement into an ngram model; obtaining the context occurrence probability of each segmented word in a plurality of segmented words corresponding to the to-be-judged statement output by the ngram model; carrying out product calculation on the context occurrence probability of each segmented word in the plurality of segmented words corresponding to the to-be-judged statement, and outputting the confusion degree of the to-be-judged statement; and comparingthe confusion degree of the to-be-judged statement with a preset confusion degree threshold, and judging the reasonability of the to-be-judged statement according to a comparison result. The problem that students cannot judge the reasonability of statements spoken by themselves under the condition that no professional teacher is present in existing speech training is solved.

本申请涉及语义解析技术领域,特别涉及一种基于语义解析的语句合理性判断方法、装置、计算机设备。所述方法包括:建立ngram模型,获取用户输入的待判断的语句;对待判断的语句进行分词处理,获得待判断的语句对应的多个分词;将待判断的语句对应的多个分词载入ngram模型;获取ngram模型输出的待判断的语句对应的多个分词中各分词的上下文出现概率;将待判断的语句对应的多个分词中各分词的上下文出现概率进行乘积计算,输出待判断的语句的困惑度;将待判断的语句的困惑度与预设困惑度阈值进行比较,根据比较结果,判断待判断的语句的合理性。旨在解决在现有的话术培训中,在没有专业老师在场的情况下,学员不能判断自己所说语句的合理性的问题。
