Embodiment 1

[0050] figure 1 The user comment text mining method in this embodiment is shown. Such as figure 1 As shown, the user comment text mining method includes the following steps:

[0051] S10: Perform data preprocessing on user comments to be analyzed, and obtain a corresponding set of words to be analyzed and a set of parts of speech to be analyzed.

[0052] Wherein, the user comments to be analyzed refer to user comments that have not been subjected to text mining and have not obtained text features. The set of words to be analyzed includes at least one word to be analyzed, and the word to be analyzed may or may not include an emotion word to be analyzed. The part-of-speech set to be analyzed includes a part-of-speech tag corresponding to each word to be analyzed, wherein the part-of-speech tag includes but is not limited to emotional words, adjectives, nouns, and verbs.

[0053] Further, in step S10, the data preprocessing of the user comments to be analyzed includes: perfor...

Embodiment 2

[0092] Corresponding to the user comment text mining method in the above embodiment 1, figure 2 A structural block diagram of a user comment text mining device corresponding to the user comment text mining method provided in Embodiment 1 in this embodiment is shown. The user comment text mining device can realize the details of the user comment text mining method in Embodiment 1 and achieve the same technical effect, so details will not be repeated here. Such as figure 2 As shown, the user comment text mining device includes a preprocessing module 10 , an emotional word judgment module 20 , an emotional word acquisition module 30 , a primary feature extraction module 40 and a deep feature extraction module 50 .

[0093] The preprocessing module 10 is used to perform data preprocessing on user comments to be analyzed, and obtain corresponding word sets to be analyzed and part-of-speech sets to be analyzed;

[0094] Emotional word judging module 20, for judging whether there...

Abstract

The invention discloses a user comment text mining method and device. The user comment text mining method includes the steps that to-be-analyzed user comments are subjected to data preprocessing, and a corresponding to-be-analyzed word set and a corresponding to-be-analyzed word class set are acquired; whether emotion word labels exist in the corresponding to-be-analyzed word class set or not is judged; if yes, a to-be-analyzed emotion word set is acquired from the to-be-analyzed word set based on the emotion word labels, and a to-be-analyzed syntactic structure set corresponding to the to-be-analyzed emotion word set is acquired; the to-be-analyzed emotion word set and the to-be-analyzed syntactic structure set are subjected to feature extraction through a preset emotion word-syntactic rule dictionary, and a primary feature extraction result is obtained; the primary feature extraction result is subjected to emotion polarity classification, and a deep feature extraction result is obtained. The operation process of the deep feature extraction result obtained through mining of the user comment text mining method is simple and convenient, it is not needed to consume a large amount of manpower and a large number of material resources, and the processing efficiency and accuracy can be improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a user comment text mining method and device. Background technique [0002] With the rapid development of Internet information technology, especially the popularization of applications such as Weibo, e-commerce, and social networks, user comment information containing user emotions in the network has exploded. How to mine valuable information from user comment information It has become the focus of attention of various industries. User comments have the characteristics of limited length, unclear subject and obvious characteristics. Text mining method is a method to obtain key information from massive data, including but not limited to text feature extraction and classification and clustering of text features, etc. It is widely used in popular fields such as the Internet and big data. Existing text mining methods include text mining methods based on word f...
