Embodiment 1

[0050] Please refer to figure 1 , the network public opinion analysis method of the present embodiment mainly comprises the following steps:

[0051] Step 101: Set the public opinion keywords of public opinion concerns, and capture and record a data set containing some network public opinion information related to the public opinion keywords according to the public opinion keywords;

[0052] Step 102: Perform sentiment analysis on the data set;

[0053] The steps to perform sentiment analysis on this dataset also include:

[0054] Step a: Preprocessing each frame of network public opinion information based on the pre-trained deep neural network model to output word vector matrix and / or character vector matrix;

[0055] Step b: Input the word vector matrix and / or character vector matrix into the word order fusion neural network, and extract public opinion features from each frame of network public opinion information;

[0056] Step 111: Determine whether the online public op...

Embodiment 2

[0095] Figure 5 It is a schematic diagram of the hardware structure of the network public opinion analysis system 600 provided by the embodiment of the present application, as shown in Figure 5 As shown, the system equipment 600 includes:

[0096] one or more processors 610 and memory 620, Figure 5 A processor 610 is taken as an example. The memory 620 stores instructions that can be executed by the at least one processor 610, that is, a computer program 640. When the instructions are executed by the at least one processor, the at least one processor can execute the network public opinion analysis method.

[0097] The processor 610 and the memory 620 may be connected via a bus or other means, Figure 5 Take connection via bus as an example.

[0098] The memory 620, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs, non-volatile computer-executable programs and modules, such as the program corresponding to the network...

Abstract

The invention relates to a network public opinion analysis method and system. The network public opinion analysis method comprises the steps: setting public opinion keywords of public opinion focus points, capturing and recording a data set which is related to the public opinion keywords and contains a plurality of pieces of network public opinion information according to the public opinion keywords, and carrying out the sentiment tendency analysis on the data set, wherein the step of carrying out sentiment analysis on the data set further comprises the following steps: a, preprocessing each frame of network public opinion information based on a pre-trained deep neural network language model to output a word vector matrix and/or a character vector matrix; b, inputting the word vector matrix and/or the character vector matrix into a word sequence fusion neural network, and performing public opinion feature extraction on each frame of network public opinion information; and repeating thestep a and the step b to establish a public opinion feature set of the data set, and outputting an emotion tendency analysis result of the public opinion on the attention point according to the public opinion feature set. The network public opinion analysis method and system can automatically monitor the internet public opinion in the specific professional field in real time.

Description

technical field [0001] This application relates to the technical field of Internet information search and analysis, in particular to a method and system for analyzing network public opinion. Background technique [0002] The Internet provides an information exchange platform, allowing users to freely share their ideas, comments, etc. on the Internet. [0003] To a certain extent, online public opinion represents the current trend and word-of-mouth of a specific industry. Therefore, practitioners in the field of construction and real estate need to have a good understanding of the status of network news and be able to monitor public opinion. Sentiment analysis in the field of construction and real estate needs to analyze the Internet information, such as news, Weibo, public account articles, etc., to discover the emotional tendency of evaluating projects or events in the field of construction and real estate, so as to judge the impact of Internet public opinion on specific p...
