Description

Internet public opinion cloud platform

Technical Field

The invention relates to the field of network public opinion information or data management, in particular to a network public opinion cloud platform.

Background

At present, the technical means of the public opinion monitoring system mainly takes the collection of internet public opinion data as a main part, the technical threshold is low, many software companies, university institutions, traditional media, even public relations companies and the like are surrendered into the industry, and various public opinion products (hereinafter, public opinion product providers are called as 'public opinion manufacturers') are provided. However, most public opinion manufacturers have low autonomous innovation ability, and mutual plagiarism causes serious homogenization. There is also a misroad for the understanding of network public opinion technical services by many user units, one typical example being the server "tiling theory", which considers that by a large investment of equipment and bandwidth, sufficient acquisition and storage capacity can be formed, thus realizing so-called "whole network monitoring". The phenomenon that the public opinion systems are respectively administrative and scattered little bad is serious, the waste of bandwidth and calculation resources is serious, and repeated collection and storage of the same public opinion data source are serious. The public opinion service industry has the scale effect of natural monopoly, and can obtain more data accumulation only by continuous large resource investment, thus forming a forward feedback loop. However, the current low-level market competition mode enables public opinion enterprises to have no need of fine tillage and fine work, price war is increasingly carried out, and market popularization cost extrudes investment in the aspects of technology research and development, equipment upgrading and updating and the like.

The following problems generally exist in the current public opinion monitoring industry.

Firstly, public opinion manufacturers are numerous, and at present, the public opinion manufacturers lack standard supervision, and lack standard analysis indexes as quantitative basis, so that the internal consumption of public opinion management is serious.

And secondly, an effective public opinion data aggregation system is lacking. The public opinion monitoring working process mainly relies on public opinion manufacturers to acquire related data through various acquisition technologies for processing, the data acquisition results are mostly mastered inside the public opinion manufacturers, and different public opinion manufacturers can acquire the same source data at the same time, so that redundant acquisition is caused, and resource waste is caused.

Thirdly, a coordination mechanism for data processing and analysis overall is lacked. The single public opinion manufacturer is often limited by factors such as company scale, fund scale, geographic position, customer demand and the like, the acquired data range is different, each public opinion manufacturer only considers own factors to acquire data, the data acquisition range is narrow, and the data processing capability is limited by the public opinion manufacturer providing service. Public opinion supervision and use departments can only use data provided by public opinion service manufacturers, lack data sharing, and the public opinion data requirements cannot be met to the maximum.

The priority of the specific emergency network public opinion event keyword group is higher than that of the conventional cloud platform unified keyword group, and the specific emergency network public opinion event keyword group is received by the public opinion system, then is subjected to priority matching, and related data are packaged and shared to the public opinion cloud platform at the first time.

The key word group and the combined database management subsystem enable the access public opinion systems to be fully utilized through the key word group gathering module, the key word group distribution module and the database storage module, and the network public opinion data are integrated and exchanged and shared uniformly through the public opinion cloud platform, so that the comprehensive application and the scheduling of the network access public opinion systems are formed, and the data utilization rate is improved. Meanwhile, the system can realize high-timeliness collaborative monitoring on emergency or major emergencies.

Further, the keyword group and the combined database management subsystem also comprise a public opinion cloud data management module which comprises data resource integration, manages the cleaning and conversion process of the data collection of the public opinion cloud platform, provides standardized flow and specification for the process, and ensures that the cleaned and converted data are available; the data resource catalogue classifies the data of the public opinion cloud platform and forms the data resource catalogue so as to facilitate the management and inquiry of the data; data standard management, namely collecting standard specification information required by data resource management, and forming a public opinion cloud combined database into a standard database; data security access management, namely establishing hierarchical rights management for the process of accessing the public opinion cloud combined database, and ensuring the security of the data in the process of accessing; and data tag management, namely constructing a unified marking system of the public opinion cloud platform aiming at key word groups of each access public opinion system to form a tag specific to each access public opinion system, so that the public opinion cloud platform is convenient for carrying out data distribution on each access public opinion system.

Considering that the public opinion cloud platform data aggregate mass public opinion data such as various forums, websites, microblogs, weChats, traditional media information and the like, the data structure is complex, the data types are various, and the data maintenance work becomes complex and heavy, so that a set of convenient, efficient and safe data management system is established through the public opinion cloud data management module. The public opinion cloud platform provides data management and monitoring functions from different layers such as data resource directory service, data resource integration process, data standard management, data security access management, data keyword management of each access public opinion system, data tag library management and the like.

As shown in fig. 2, when the subsystem performs data management, the keyword groups of all accessed public opinion systems are collected, and a cloud platform unified keyword group is constructed; the public opinion cloud platform distributes cloud platform unified key word groups to all access public opinion systems, and all access public opinion systems match data acquired by the access public opinion systems according to the cloud platform unified key word groups; each access public opinion system shares effective network public opinion data which is not required by the public opinion system and is matched with the unified keyword group of the cloud platform to the public opinion cloud platform; and collecting the effective network public opinion data provided by each access public opinion system by the public opinion cloud platform, forming a public opinion cloud combined database, and distributing the corresponding public opinion data to the cloud platform according to the cloud platform unified key word group corresponding to each access public opinion system.

In the prior art, all user units served by the current network access public opinion systems belong to independent purchasing and the access public opinion systems built in a self-built and self-used mode are subjected to four stages of monitoring processes of acquisition, comparison, display and analysis independently. The user units need to collect the content of the basic similar main websites, so that most technical resources accessed to the public opinion system are dissipated in the repeated redundant collection process from the global aspect, and the pages collected each time only extract the useful information of interest of the unit because only key word groups focused by the unit are configured. A large amount of valid information not of the unit is directly discarded because no keyword configuration is performed; from the global level, technical resources such as calculation storage and network bandwidth of the access public opinion system which are built by user units of all departments of each place are in a larger internal consumption state due to lack of a unified integration scheduling platform covering heterogeneous access public opinion system networks operated by a plurality of public opinion companies.

The public opinion cloud platform can gather key phrases required or provided by each accessed public opinion system, and after the cloud platform unifies the key phrases according to certain rules, the cloud platform unifies the key phrases and distributes the key phrases to each accessed public opinion system, so that each accessed public opinion system can match not only the key words focused by the cloud platform unifies the key phrases on the basis of original acquired data, thereby simultaneously extracting data information corresponding to the key words of the cloud platform and data information corresponding to the cloud platform unifies the key phrases, sharing the data information corresponding to the cloud platform unifies the key phrases to the public opinion cloud platform, and the cloud platform can distribute the corresponding public opinion data to the cloud platform unifies the key phrases according to the cloud platform unifies corresponding to other accessed public opinion systems for the first time, thereby facilitating the other accessed public opinion systems to receive the required data information from the public opinion cloud platform. The public opinion cloud platform and the keyword group management method are used for integrating and exchanging the network public opinion data uniformly to form comprehensive application and scheduling of the network access public opinion system, and the data utilization rate is improved. Meanwhile, according to the effective network public opinion data provided by each access public opinion system, a public opinion cloud combined database is formed, and the data stored in the public opinion cloud combined database are all effective or useful data, so that the public opinion cloud combined database has public opinion value.

Each access public opinion system determines the key word groups required by the public opinion system and marks the key word groups and then shares the key word groups to the public opinion cloud platform, and the public opinion cloud platform performs compliance checking on the key word groups; if the combination rule is collected, the keyword groups are subjected to duplication removal and integration, and a cloud platform unified keyword group is constructed; if the rule is not met, the rule is fed back to the corresponding access public opinion system and is required to be adjusted or modified to be met.

The key word group and the combined database management subsystem perform compliance checking on the key word group provided by the accessed public opinion system, and the difference of the different accessed public opinion systems in the key word group form can be effectively avoided through the compliance checking on each accessed public opinion system. And the key word groups are de-duplicated and integrated, and the cloud platform unified key word groups are determined, so that each access public opinion system is relatively unified, and the key word groups of all clients served by each access public opinion company are included, so that the full coverage of data matching is ensured, and the operation accuracy and the operation efficiency of the public opinion cloud platform are ensured.

The labeling mode of key word groups required by each access public opinion system is as follows: the labeling content comprises company name and user name of the access public opinion system, and the labeling form is a unique identification. For example, the labeling rule may be preferably XnYm, where n in Xn is a unique code of the public opinion cloud platform for accessing the public opinion system, m in Ym is a unique code of the public opinion system for accessing the public opinion system to the user, for example, X0001Y001 indicates the 0001 th user accessing the public opinion cloud platform for accessing the 001 th user of the public opinion system.

The access public opinion system can also send data requests according to own requirements, and after the keyword groups and the combined database management subsystem audit the data requests, the public opinion data containing keywords required by the access public opinion system are packaged and sent. The access public opinion system can also actively send related data requests to the keyword groups and the combined database management subsystem according to the change of the self requirements, and obtain related public opinion data after the public opinion cloud platform is audited, so that the access public opinion system can quickly and conveniently obtain various public opinion data, and the service quality and the service efficiency of the access public opinion system are facilitated to be provided.

Second preferred embodiment,

As shown in fig. 4, in this embodiment, a standard library subsystem and a subsystem configured to optimize access to public opinion system are added on the basis of the first preferred embodiment.

The standard library subsystem comprises a keyword group standard module, a public opinion data format standard module, a public opinion data exchange standard module and a network public opinion data analysis model standardized operation environment module.

The keyword group standard module is used for restraining the keyword data format uploaded to the keyword group gathering module by the public opinion manufacturer; the public opinion data format standard module is used for restraining the effective network public opinion data format acquired by the public opinion cloud data storage module; the public opinion data exchange standard module is used for restraining a data exchange process in the data analysis model exchange subsystem; the standardized running environment module of the network public opinion data analysis model establishes standardized input and output standards.

The network public opinion data sharing exchange mechanism mainly comprises public opinion keyword standards, public opinion data format standards, public opinion data exchange standards and the like. Meanwhile, after standardized constraint is carried out on public opinion data, a public opinion core database is further constructed, so that a channel is provided for sharing and exchanging public opinion data among users and between users and platforms, and the public opinion data is shown in fig. 5.

Public opinion keyword criteria. Because the keyword data collected by each public opinion manufacturer has more sources and types and a large amount of repeated data, the platform formulates corresponding network public opinion keyword standards. Such as the key words "security + (greedy |counterfeit |academic falsification)", namely "security greedy", "security counterfeit", "security academic falsification". In this way, a plurality of keywords can be connected into one character string, and the relationship between the keywords can be intuitively understood. Each manufacturer firstly needs to perform stop word removal and repeated data removal processing on the respective keyword data, and then changes the keyword data format to meet the platform standard requirements before uploading the keyword data format to the platform, so that the quality and standardization level of the data are improved.

Public opinion data format standard. Aiming at the problem that the public opinion data formats provided by public opinion manufacturers are not uniform, corresponding format standards are formulated to restrict the formats of the network public opinion data, as shown in table 1.

Table 1 network public opinion data format standard requirement field

Before uploading the public opinion data to the platform, each manufacturer should adjust the format of the public opinion data according to the standard, splice the fields with the corresponding content in the public opinion data, and upload the fields to the platform in the form of JSON or XML. By the mode, the public opinion data can be stored and managed conveniently by the platform, and a user can clearly and intuitively know related information of the public opinion data.

Public opinion data exchange criteria. In the standard, after a user submits data to a platform according to a data format standard, the platform calculates the relevance and similarity index of the keywords according to the data provided by the user, and the data is audited according to the relevance and similarity index. After the verification is passed, the platform stores the analysis result and the original data together into a database. When the user needs to acquire public opinion data by using the platform, the platform only needs to send the keywords to the platform, and then the platform forwards the request to other public opinion manufacturers. When other public opinion manufacturers upload corresponding data, the platform firstly carries out auditing on the data uploaded by the manufacturers, and after the auditing is passed, the data provided by the public opinion manufacturers, the corresponding data in the platform public opinion core database and the data analysis result of the platform are returned to the user together, so that the requirements of the user are met to the maximum extent, and meanwhile, convenience is brought to the data screening and analysis work of the user.

As shown in fig. 6, when the subsystem configured by the optimized access public opinion system recommends the optimized configuration for the network public opinion data collection strategy of each access public opinion system, on one hand, the data collection strategy of each access public opinion system is proposed with the optimized configuration suggestion by analyzing the network public opinion data which is mutually forwarded by the public opinion cloud platform of each access public opinion system in a period of time, and the collaborative coordination of each access public opinion system in the aspect of website data collection is promoted, so that the overall network public opinion data collection efficiency is improved; on the other hand, the collection is connected to the network public opinion data analysis model of each public opinion system of the public opinion cloud platform, and the network public opinion data analysis model with low adoption rate is screened from the network public opinion data analysis models with similar functions and more submitted quantity and fed back to the related access public opinion system, so that the research and development investment of the related model is recommended to be regulated.

And in the redundancy elimination process of the collected network public opinion data collection model, the redundancy is reduced after the range of the collection website is negotiated and cooperated. The method comprises the steps of selecting a website with the configuration rate 2 times higher than the average configuration rate as a high-configuration-rate acquisition website during negotiation, selecting a website with the configuration rate 1/2 lower than the average configuration rate as a low-configuration-rate acquisition website, pushing suggestions for reducing configuration to public opinion companies related to the access public opinion system if the acquisition frequency of the high-configuration-rate acquisition website is higher than the data updating frequency, and pushing the acquisition website with the low configuration rate to the suggestions for increasing configuration of the related access public opinion system according to the category to acquire the website.
