Abstract

The invention discloses a Chinese herbal medicine plant picture capturing method based on a professional term vector of the traditional Chinese medicine and pharmacy field. The Chinese herbal medicine plant picture capturing method comprises the following steps: firstly, selecting and collecting traditional Chinese medicine and pharmacy text data, text information of medicine books and dictionary entry information relevant to traditional Chinese medicine and pharmacy, captured from an encyclopaedia website; secondly, training a Word2Vec model by using the text data so as to obtain professional term vectors of the traditional Chinese medicine and pharmacy field; then, acquiring a candidate picture set and text information thereof on source web pages through an image retrieval function based on texts provided by common search engines, such ash Google and Baidu, and calculating characteristic vectors of the source web pages by using a Doc2Vec model; finally, according to the similarity of the characteristic vector of the source web page and the corresponding Chinese herbal medicine term vector, rearranging the candidate picture set, and selecting a plurality of pictures arranged at the front, and de-duplicating the picture set by using a perceptual hash algorithm so as to obtain a final picture set.
