[0043] The application scenario of a data collection and processing method of the present invention is as Figure 1 shown. Under the existing technical conditions, the collection of public opinion data often has problems such as low processing efficiency, incomplete information mining, single display form, and inability to effectively support decision - making.

[0044] Next, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0045] In an embodiment disclosed by the present invention, as Figure 2 shown, a data collection and processing method includes:

[0046] Step S201, building a database based on the obtained number of public opinion information, where each piece of public opinion information includes problem information;

[0047] In this embodiment, a database is constructed based on a number of pieces of public opinion information obtained, including: obtaining public opinion information through Internet collection and / or obtaining public opinion information through manual entry.

[0048] Exemplarily, obtaining public opinion information through Internet collection may be collecting public opinion data from multiple sources, such as Jin Yun, Northern Network, Weibo, Xiaohongshu, etc., and constructing a database with the collected data. Each piece of public opinion information includes attribute information such as date, title, question, website, department or region.

[0049] In the database, an example of a piece of public opinion information is as follows:

[0050]

[0051] Exemplarily, obtaining public opinion information through manual entry may be by designing a data entry interface and just filling in the data; or using a data update method, that is, uploading newly obtained public opinion data to the database in a batch format to maintain the timeliness and freshness of the public opinion data.

[0052] Step S202: Based on the address information in the question information included in each piece of public opinion information in the database, establish a scatter plot map and / or a heat map;

[0053] Step S203: Based on the question information included in each piece of public opinion information in the database, establish a knowledge graph;

[0054] Step S204: Generate public opinion data-based perception information based on the combination of the scatter plot map and / or the heat map and the knowledge graph;

[0055] Step S205: Make a decision based on the public opinion data-based perception information.

[0056] Based on the previous embodiment, in another embodiment of the present invention, as Figure 2 shown, step S202, based on the address information in the question information included in each piece of public opinion information in the database, establish a scatter plot map and / or a heat map, including: determining the longitude and latitude information corresponding to the address information according to the matching relationship between the address information and the place name address library, or inputting the address information into an electronic map to determine the longitude and latitude information corresponding to the address information;

[0057] In this embodiment, exemplarily, as Figure 4 shown:

[0058] In the question attribute column of the public opinion information, extract the address name in the text to form a new address name attribute column, then match it with the place name address library to obtain the corresponding longitude and latitude information, and then form a new longitude and latitude attribute column.

[0059] In another form, the address name is input into the Baidu Map or Amap API to obtain the corresponding longitude and latitude information, and then a new longitude and latitude attribute column is formed;

[0060] According to the longitude and latitude information corresponding to each piece of public opinion information, corresponding projection points are established on the map to obtain a scatter plot;

[0061] Exemplarily, through point projection based on the longitude and latitude information, multiple pieces of public opinion information can be displayed on the map, and the coordinates of each longitude and latitude information can be used as a projection point.

[0062] According to the longitude and latitude information corresponding to each piece of public opinion information, a heat map is obtained using the spatial kernel density method.

[0063] Given a point dataset including n projection points in the map, calculate the point density estimate value f(x, y) of the target point (x, y) in the map. Based on the point density estimate value f(x, y) of each target point (x, y), a corresponding heat map is established. The process is as follows:

[0064]

[0065] where f(x, y) is the point density estimate value of the target point (x, y);

[0066] n is the total number of points in the point dataset;

[0067] (x i , y i ) is a point coordinate in the point dataset, 1 ≤ i ≤ n;

[0068] r is a preset radius, also known as the smoothing parameter;

[0069] The derivation process of formula (1) is as follows:

[0070] The formula (2) for kernel density estimation is as follows:

[0071]

[0072] where f(x, y) is the point density estimate value of the target point (x, y);

[0073] n is the total number of points in the point dataset;

[0074] (x i , y i ) is a point coordinate in the point dataset, 1 ≤ i ≤ n;

[0075] r is a preset radius, also known as the smoothing parameter;

[0076] K(.) is a kernel function. Commonly used kernel functions include Gaussian kernel, uniform kernel, triangular kernel, etc. In this embodiment, the Gaussian kernel is used, and the formula is as follows:

[0077]

[0078] Where,

[0079] Formula (1) is obtained by substituting Formula (3) into Formula (2);

[0080] In this embodiment, r is set to 500 meters;

[0081] An example of the heat map is as Figure 7 shown.

[0082] Based on the previous embodiment, in another embodiment of the present invention, as Figure 2 shown, step S203, according to the problem information included in each piece of public opinion information in the database, establish a knowledge graph, including: as Figure 5 shown, the problem information included in each piece of public opinion information is input into the artificial intelligence large model for answering, and the corresponding third-level label and sentiment intensity information of the problem information included in each piece of public opinion information are obtained;

[0083] Exemplarily, the artificial intelligence large model is the Wenxin Yiyan large model. By calling its interface through the API, taking the problem text data of the public opinion information as the input, and adding the requirement of classifying the above public opinion data into three levels and performing sentiment analysis, a piece of text will be returned, obtaining the third-level label and sentiment intensity information of the input problem. When generating a new artificial intelligence attribute column for the result, calling the artificial intelligence large model once can return the third-level label and sentiment intensity information corresponding to the problem of a piece of public opinion information.

[0084] In this embodiment, as Figure 5 shown, the sentiment intensity information is judged and output by the artificial intelligence large model itself. Only the samples judged in the model need to be input. Exemplarily, the sentiment intensity information can be any one of positive, negative, and neutral.

[0085] Establish a knowledge graph according to the third-level label corresponding to the problem information included in each piece of public opinion information.

[0086] Exemplarily, according to the third-level label corresponding to the problem information included in the public opinion information, it is converted into relational network data with an associated relationship, specifically a hierarchical structure of "root node → first-level label → second-level label → third-level label", forming the skeleton of the knowledge graph, specifically including node Node and connection relationship Edge data tables. The knowledge graph or word cloud form is displayed according to the node Node and connection relationship Edge data tables, and the sentiment intensity situation of the problem can be obtained through the sentiment intensity information.

[0087] Based on the previous embodiment, in another embodiment of the present invention, as Figure 2 and Figure 3 shown, in step S203, generating the public opinion data-based perception information based on the combination of the scatter map and / or the heat map and the knowledge graph further includes: generating the public opinion data-based perception information based on the combination of the scatter map and / or the heat map, the emotional intensity information, the knowledge graph, and the on-site information.

[0088] In another embodiment of the present invention, the scatter map and / or the heat map can be fused with other spatial image data, such as land use planning maps, building vector maps, high-resolution remote sensing maps, etc., to achieve superposition, providing data image support for later thematic scene applications.

[0089] Exemplarily, the public opinion data-based perception information can also generate a data overview module: intuitively displaying the public opinion information data in multiple dimensions, including: total amount statistics of public opinion data, list display, data source distribution analysis; change trends of annual, quarterly, and monthly data volumes; top 20 rankings of public opinion hotspots; rolling tracking of people's livelihood hotspots, etc., to help users quickly understand the general situation of public opinion data.

[0090] In this embodiment, the on-site information includes: on-site photo information and / or remote sensing image information.

[0091] In one embodiment, as Figure 6 shown, by fusing with other multi-source data, such as on-site photo information and / or remote sensing image information, a comprehensive visual display system is constructed to provide support for decision-making.

[0092] Exemplarily, for example, through remote sensing image information, scatter maps and / or heat maps, and knowledge graphs, the service efficiency of snow removal public services after winter snowfall is judged. From the feedback of the public opinion data-based perception information, the main concentrated areas of public opinion, the concentrated problems, and the immediate on-site remote sensing snow removal situation can be understood, providing strong support for decision-making.
