Abstract

The invention provides a viewpoint extraction method and device, and belongs to the technical field of data processing. The method comprises the steps of performing word segmentation processing on to-be-processed comment information to obtain to-be-processed segmented words; obtaining the part-of-speech and dependency relationship of the to-be-processed segmented words; and according to the part-of-speech and / or the dependency relationship, performing viewpoint extraction on the to-be-processed segmented words according to a preset template to obtain viewpoint information of the to-be-processed comment information. According to the method, the viewpoint information of which the part-of-speech and / or dependency relationship conforms to the preset template is extracted from the to-be-processed information according to the part-of-speech and dependency relationship among the segmented words in the to-be-processed information, and the obtained viewpoint information is more accurate and caneffectively express the user viewpoint due to consideration of the part-of-speech and dependency relationship of the segmented words.

Description

technical field [0001] The invention belongs to the field of data processing, in particular to a viewpoint extraction method and device. Background technique [0002] With the development of the network environment, users can obtain more and more products and services through the network. Users can also post their own comments on various services and products on various service platforms. For platform operators, analyzing user comments can help them understand the user's demand trends, so that they can improve their own services and products and promote their own development. [0003] Platform operators usually manually browse users’ comments to understand users’ opinions. This method is not only time-consuming and inefficient, but also increases if the amount of comment information is too large. Manual browsing is obvious. Some are stretched. On the other hand, the point mutual information algorithm can also be used to calculate the degree of association between candidate...
