The method comprises: acquiring text information; carrying out word segmentation on the text information to obtain segmented words w 1 , w 2 ,..., w n-1  and w n ; using a CBOW model to calculate word vectors V(w 1 ), V(w 2 ),..., V(w n-1 ) and V(w n ) of the segmented words; using a TF-IDF algorithm to calculate TF-IDF values k 1 , k 2 ,..., k n-1  and k n  of the segmented words; obtaining a sentence vector V according to products of the word vectors of the segmented words and the corresponding TF-IDF values; and calculating the cosine similarity between the sentence vector V and sentence vectors of pre-stored statements, and determining a pre-stored statement having the maximum cosine similarity. By means of the process, a pre-stored statement that is most similar to text information can be found, and the accuracy of problem recognition can be improved in the aspects of robot conversation, information classification, etc., thus improving the conversation efficiency or the classification efficiency. Further provided are a computer device and a storage medium.

Abstract: A gauge-changeable wheelset, comprising wheels (6), an axle (7), and locking mechanisms; the wheels (6) are respectively provided at either end of the axle (7), and are connected to the axle (7) by means of splines; the locking mechanisms are respectively provided at the outsides of the wheels (6) and located in axle boxes at either end of the axle (7), the locking mechanisms being connected to the wheels (6) and used for locking and unlocking the wheels (6), so as to realize a gauge change of the wheels (6). The gauge-changeable wheelset has a simple structure, and requires little change of existing vehicle structures, facilitating mass modification of existing vehicles, improving the versatility and reliability of the gauge-changeable wheelset.
