Method and device for identifying information

A device for identifying information, comprising:

• at least one processing unit;
• and
• at least one storage unit connected to the at least one processing unit, wherein the storage unit has program codes stored thereon, which when being executed by the processing unit, cause the processing unit to:
• acquire a word vector matrix of the information;
• for each of a plurality of convolutional kernel widths of a convolutional neural network, convolve each convolutional kernel corresponding to the width with the word vector matrix of the information to acquire a convolutional vector corresponding to each convolutional kernel, and perform a maximum pooling operation on each convolutional vector to acquire an identification feature corresponding to the width;
• combine identification features corresponding to various convolutional kernel widths to acquire an identification feature of the information;
• and
• identify the information according to similarity of the identification feature of the information.
