An embodiment of the invention provides a webpage
topic sentence extraction method. The method comprises: firstly, obtaining a to-be-determined webpage, wherein the to-be-determined webpage contains a plurality of alternative topic sentences, and each alternative
topic sentence contains a plurality of segmented words; secondly, determining a word feature value of each segmented word, inputting the word feature value into a preset
machine learning model to obtain a partial order value of the segmented word, and further according to the partial order value of the segmented word, determining a partial order value of each alternative
topic sentence; and finally, determining the alternative topic
sentence with the partial order value greater than a preset threshold as a target topic
sentence. According to the embodiment of the invention, the partial
order values of the alternative topic sentences are obtained by utilizing the
machine learning model; the
machine learning model can reflect a degree of correlation between a
query statement and a recalled webpage, so that the determined partial
order values are more accurate and the accuracy of selecting the target topic
sentence is improved. In addition, the invention furthermore provides a webpage topic
sentence extraction apparatus, which is used for ensuring the application and implementation of the method in practice.
