Abstract

The embodiment of the invention provides a comment information marking method and a comment information marking device. The method comprises the following steps of: obtaining data of a plurality of event comments; performing statement division on each event comment, and using each divided statement as a comment viewpoint; extracting sentiment words from each comment viewpoint; associating the sentiment words co-occurring in any one comment viewpoint and building a sentiment word community network; and marking data with the sentiment property for the sentiment word affiliated comment viewpoint in any one sentiment word community in the sentiment word community network, wherein the sentiment property is positive, negative or neutral, and the sentiment word community comprises a group of directly or indirectly associated sentiment words. The comment information marking method and the comment information marking device provided by the embodiment of the invention have the advantages that the event comments can be automatically subjected to sentiment clustering; and the sentiment properties can be marked for the event comments.

Description

technical field [0001] The invention relates to the technical field of network information processing, in particular to a comment information marking method and device. Background technique [0002] Usually, the existing review clustering methods are mostly about product reviews, such as user reviews in Tmall, Amazon and other websites. It mainly clusters reviews around different attributes of products. Generally speaking, first construct the categories of attributes, secondly mine the included attributes from reviews, and then classify the reviews into the categories of included attributes. Among them, methods such as dictionary-based and machine learning-based methods are often used to mine attributes from reviews. [0003] However, event reviews are fundamentally different from item reviews, and most event reviews have no attributes. Therefore, it is impossible to simply apply the product clustering method to event reviews. Second, the content of event reviews is rela...
