摘要

The present disclosure relates to a web page training method and device. The method includes: obtaining a training web page set of a manually annotated class, and generating a web page vector of a web page in the training web page set, specifically including: obtaining an effective history query character string of a first training web page in the training web page set, and performing word segmentation on the effective history query character string; obtaining an effective quantity of times of each segmented word, the effective quantity of times being a total quantity of times the segmented word occurs in the effective history query character string; calculating a segmented word weight of each segmented word according to the effective quantity of times of each segmented word; generating a web page vector of the first training web page according to each segmented word and the corresponding segmented word weight; and generating a web page classification model according to the manually annotated class of the web page in the training web page set and the corresponding web page vector. Training costs are low, efficiency is high, and class annotation may be automatically performed on a web page after the web page classification model is generated, so that an accuracy rate of an identified intention is higher. A search intention identification method and device are further put forward.
