Technical Field

[0001] The present invention relates to the technical field of brand analysis, and particularly relates to a brand communication index construction system. Background Art

[0002] With the in-depth development of the digital age, brand communication has changed from traditional advertising placement and media exposure to a multi-dimensional, dynamic, and cross-platform complex network behavior. Enterprises need to evaluate the comprehensive performance of brands on multiple channels such as social media, search engines, and e-commerce platforms through quantitative means to formulate precise communication strategies. Driven by this demand, the technology of brand communication index construction has gradually become a research and application hotspot.

[0003] The existing technology mainly relies on the static analysis of single or limited data sources and combines basic statistical models to generate evaluation indicators. However, this method faces significant bottlenecks in practical applications, such as insufficient data integration capabilities, rigid analysis models, and very lagging strategy optimization and decision support, which lead to serious deficiencies in the accuracy, real-time performance, and adaptability of traditional brand communication indexes. Summary of the Invention

[0004] The main purpose of the present invention is to provide a brand communication index construction system, which can effectively solve the problems of insufficient data integration capabilities, rigid analysis models, and very lagging strategy optimization and decision support.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By constructing a full-link intelligent closed-loop system, the present invention completely solves the problems of data fragmentation and strategy lag in traditional brand communication analysis. The system integrates cross-platform data sources and uses natural language processing and automated cleaning technologies to achieve efficient fusion of multi-source heterogeneous data, breaking the limitations of data islands. The collaborative application of dynamic factor analysis and generative adversarial networks enables the system to perceive changes in the communication scenario in real time, dynamically adjust data weights and model parameters, ensuring that the analysis results are adaptively optimized with the market situation. At the same time, the linkage mechanism of the A / B test engine and genetic algorithm automates strategy recommendation, parameter optimization, and version iteration, significantly shortening the decision response time to the minute level, increasing the data coverage rate to over 95%, and improving the overall computing efficiency by 40%, providing real-time and accurate decision support for brand management.

[0021] 2.

The combination of the long short-term memory network LSTM and the graph convolutional network GCN takes into account the time law of communication trends and the spatial cascade effect of key nodes, increasing the accuracy of comprehensive index prediction by 30%.

In addition, the virtual reality VR three-dimensional sand table and the virtual-real interaction design of the dynamic force-directed graph support users to immerse themselves in testing the strategy effects and adjust parameters in real time, increasing the decision confidence by 60%, providing a high-precision deduction tool for brand defense and attack in complex communication environments.

[0023] In order to make the technical means, creative features, achieved purposes, and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figure 1 shown, a brand communication index construction system, the brand communication index construction system is configured as:

[0025] Data Acquisition System: Seamlessly access social media, search engine, and e-commerce data through cross-platform APIs, integrate natural language processing (NLP) technology to achieve real-time public opinion scraping and semantic parsing, and perform automated cleaning and standardized mapping of multi-source heterogeneous data;

[0026] Data Processing System: Construct a multi-dimensional data fusion matrix based on dynamic factor analysis method, embed an event-driven weight dynamic adjustment module, and an abnormal data detection and repair unit through a generative adversarial network (GAN);

[0027] Analysis Model System: Adopt a multi-task deep learning framework with transfer learning, synchronously optimize brand influence, audience sentiment, and communication breadth indicators, combine long short-term memory network (LSTM) time series prediction and graph convolutional network (GCN) propagation topology analysis, and embed a policy simulation module of reinforcement learning;

[0028] Visualization System: Provide a dynamic force-directed graph to display key nodes of the communication path, support industry benchmark comparison and historical data timeline backtracking, and generate an interactive VR three-dimensional sand table based on a virtual reality interface;

[0029] Feedback Optimization System: Generate real-time policy recommendations through an A / B test engine, combine genetic algorithms to achieve self-optimization of model parameters and version iteration, and dynamically adjust data weights based on a communication effect decay model;

[0030] Dynamic Update System: Real-time monitor multi-source data streams through incremental learning algorithms, then automatically trigger exponential model iteration updates based on a preset communication heat threshold, and synchronize to all system modules.

[0031] Support seamless API access to cross-platform data sources, including public and private interfaces of social media, search engines, and e-commerce platforms. The automated cleaning module uses rule engines and clustering algorithms to eliminate duplicate, noisy, and irrelevant data.

[0032] The data acquisition system docks with the open APIs of social media (such as Weibo, Twitter), search engines (such as Google, Baidu), and e-commerce platforms (such as Amazon, Taobao) through the OAuth2.0 protocol. Private interfaces use JWT token authentication and data encryption transmission to ensure the compatibility and security of cross-platform data sources; The automated cleaning module defines cleaning rules based on rule engines (such as Drools), such as de-duplication rules (repeated operations by the same user ID within 10 seconds are considered invalid) and denoising rules (records containing sensitive words in the text are directly filtered), and uses the DBSCAN clustering algorithm to identify outliers based on data features (such as publishing time, IP address), mark them as noisy data, and finally complete the standardized mapping of heterogeneous data through JSON Schema and store it in a distributed database.

[0033] The dynamic factor analysis method dynamically adjusts the weight allocation strategy according to the event labels of the propagation scenario. The GAN anomaly detection unit dynamically identifies the data noise distribution through the generator-discriminator game, and links the repair module to reconstruct the compliant data to ensure the robustness of the fusion matrix.

[0034] The data processing system defines event labels according to communication scenarios (such as new product launches and crisis public relations), uses principal component analysis (PCA) to extract key factors (such as communication speed and user engagement), and dynamically adjusts factor weights to construct a multi-dimensional fusion matrix; the GAN anomaly detection unit simulates normal data distribution through the generator, and the discriminator identifies abnormal noise data. After detecting the anomaly, the autoencoder is linked to reconstruct the compliant data distribution and update it to the fusion matrix in real time to ensure the robustness of the data; for example, in a marketing campaign scenario, the system automatically increases the weight of the "user interaction rate" factor, and at the same time uses GAN to repair abnormal data points caused by crawler errors.

[0035] The multi-task deep learning framework adopts domain adaptation technology to adapt to the brand characteristics of different industries through a small amount of labeled data. The long short-term memory network LSTM time series prediction combined with the graph convolutional network GCN can quantify the cascade effect of node influence in the propagation network and predict the interference threshold of competitor strategies on the index. The strategy simulation module embeds a non-cooperative game model to generate a counter-strategy matrix to evaluate the long-term effect of the propagation path.

[0036] The analysis model system adopts a transfer learning framework, freezes the underlying network based on the pre-trained ResNet-50 model, and fine-tunes the top-level classifier to adapt to the brand characteristics of different industries (such as fast-moving consumer goods and finance) through a small amount of labeled data. The LSTM layer inputs time series data (such as daily dissemination volume) to predict the dissemination trend in the next three days; the GCN layer inputs the dissemination network topology (user-content interaction graph) to calculate the PageRank value of the node influence, and the two are combined and weighted to generate a comprehensive evaluation index to quantify the cascading effect of node influence in the dissemination network; the strategy simulation module embeds a non-cooperative game model, constructs a payment matrix to quantify the marginal impact of competitor strategies (such as increasing advertising) on ​​the brand index, solves the Nash equilibrium strategy through reverse induction, and generates a counter-strategy matrix to evaluate the long-term effect of the dissemination path.

[0037] The dynamic force-directed graph marks high-influence nodes in real time and supports users to customize the weight parameters of the propagation path. The VR three-dimensional sandbox is generated based on the propagation network topology data, supporting perspective switching, node penetration analysis and strategy deduction in a virtual environment.

[0038] The visualization system renders dynamic force-directed graphs through the D3.js library. The size of the nodes represents the influence (such as the PageRank value), and the edge weights represent the propagation intensity (such as the number of reposts). Users can adjust the layout parameters through drag-and-drop interaction and customize the weights of the propagation paths. The VR three-dimensional sand table is developed based on the Unity engine. After importing the propagation network topology data, users can switch perspectives through the VR headset, click on the nodes to view detailed attributes (such as propagation levels, associated user groups), and simulate the network diffusion effect after strategy adjustment. For example, test the impact of different advertising placement paths on key nodes in a virtual environment.

[0039] The A / B test engine generates a priority ranking of strategies based on the comparison of real-time propagation effects. The genetic algorithm optimizes the model hyperparameters through crossover and mutation operations, and combines with the historical data validation set to achieve version iteration. The decay model dynamically adjusts the weights of old data to ensure the timeliness of exponential calculations.

[0040] The feedback optimization system randomly divides users into a control group and an experimental group through the A / B test engine, and applies different strategies (such as placement channels, content forms) respectively. It uses the chi-square test (x 2 ) to evaluate the conversion rate difference and generate a strategy priority report (such as Strategy A has a 5% improvement index); the genetic algorithm uses the model accuracy as the fitness function, and iteratively optimizes the hyperparameters (such as learning rate, number of neural network layers) through single-point crossover and Gaussian perturbation mutation operations, and finally selects the top 10 models to enter the validation set for testing; the decay model defines the exponential decay function w(t) = w0·e -λt , and dynamically reduces the weights of old data according to the data timestamp (such as setting λ = 0.1, indicating that the data half-life is 7 days) to ensure the timeliness of exponential calculations.

[0041] The dynamic update system uses the distributed message queue Kafka to achieve cross-module data synchronization, ensuring that the updated exponential model takes effect in real time, and embeds a reinforcement learning optimization module to automatically adjust the heat threshold according to the historical update effect and generate a priority queue for exponential updates.

[0042] The dynamic update system real-time monitors multi-source data streams through an incremental learning algorithm (online stochastic gradient descent). When the propagation heat threshold (such as the number of reposts per day > 100,000) is triggered, it automatically starts the model retraining process; uses the distributed message queue Kafka to create a "model_update" topic, the producer publishes the new model version information, and the consumers (such as visualization, feedback modules) subscribe and load it in real time to take effect. The reinforcement learning optimization module defines the state (current threshold, update frequency), action (increase / decrease threshold), reward (the degree of improvement in model stability), automatically adjusts the threshold through the DQN algorithm, generates a priority queue for exponential updates (such as tasks with a high degree of data mutation are processed first), and supports the version rollback function, automatically switching to the stable model version when an anomaly is detected.

[0043] The above has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
