The invention provides a recommendation question determination method and device based on financial question and answer features, which can be used in the
artificial intelligence field, the financial field or other fields, and the method comprises the following steps: carrying out word segmentation
processing on stock questions by using a word
segmentation system, determining a plurality of candidate words and word frequencies of the candidate words, and determining feature values corresponding to the candidate words; sorting the feature values, determining vector space dimensions, performing similarity calculation on each vector, and determining a similar
problem set; performing entity recognition on financial preset knowledge points to obtain
a domain knowledge graph, determining similarity between the knowledge points, and determining an effective question set according to a similarity calculation result between the knowledge points; and according to the questions input by the user, screening the similar question set and the effective question set to obtain a recommended effective question set. The problem of how to quickly recommend effective questions to the user in the prior art is solved, the provided
questions and answers better conform to the expectation of the user, the recommendation efficiency and accuracy are improved, human resources are saved, and the user experience is improved.
