Problems solved by technology

Text analysis methods based on the described features are not suitable for short texts
[0005] In addition, because short texts and long texts appear to be more casual and colloquial in terms of wording, the characteristics will reduce the accuracy of conventional text analysis algorithms; Comment data, etc.) has a high accuracy rate, but the analysis effect of comment data with short text, emphasis on colloquialism, and extensive content is relatively poor and not accurate enough
[0006] In addition, in the prior art, due to the above-mentioned poor and inaccurate analysis results for short texts, the analysis results based on short texts in the search engine are not effective when building a search engine for the target object, and the results returned to the client are also not accurate enough, resulting in Waste of related network resources

Abstract

The invention provides a comment data processing method and device and relates to the technical field of networks. The method comprises the following steps: presetting a feature word lexicon and a sentiment word lexicon; based on the feature word lexicon and the sentiment word lexicon, processing the comment data, wherein the processing comprises the following steps: according to commodity information, obtaining comment data corresponding to the commodity information; according to the feature word lexicon, determining feature words in each piece of comment data; according to the sentiment word lexicon, determining effective sentiment word corresponding to each feature word in the comment data and the orientation value of the sentiment word; according to the corresponding relation of the sentiment words and the feature words and the orientation value of each sentiment word, computing the feature value of each feature word in each piece of comment data. With adoption of the application, the features of commodity on different aspects can be analyzed to obtain the sentiment orientation of the commodity in every aspect from a commentator, the accuracy rate of analyzing the comment data with the characteristics of short text, emphasis on colloquialism and the like is increased, and the utilization rate of the relevant network resources can be increased.
