Device and method for detecting purpose of article

A device for detecting a purpose of an article comprising:

• a transceiver;
• a storage configured to store a feature identification model and a specific purpose detecting model;
• and
• a processor electrically connected to the storage and the transceiver, and being configured to perform operations comprising:
• receiving a first article via the transceiver;
• dividing the first article into a plurality of first sentences;
• inputting the first sentences to the feature identification model to generate a first contextualized word vector corresponding to each of the first sentences;
• inputting the first contextualized word vector of the first sentences in the first article to the specific purpose detecting model to generate a distributed representation similarity of the first article;
• and
• determining that the first article conforms to a first specific purpose when the distributed representation similarity is greater than a first threshold.
