Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marketing intelligent decision-making, and particularly relates to a marketing intelligent decision-making system based on multi-modal learning. BACKGROUND

[0002] In the current digital marketing environment, enterprises face core challenges such as difficulty in integrating multi-source heterogeneous data, lag in decision-making response, and weakness in risk control. Traditional marketing decision-making systems usually rely on a single data modality, leading to one-sided cognition of product market performance. For example, social media text analysis can only capture user emotional tendencies, but cannot correlate with advertising effectiveness or real-time consumer behavior; while transaction data analysis can reflect sales results, it is difficult to trace the decision-making causes. Existing technologies attempt to improve decision-making efficiency through simple rule engines or multi-model parallel processing, but each modality data is still in a fragmented state, and text, video advertising performance and transaction behavior data lack deep coupling, making the system unable to capture key associations such as "how does emotional feedback after users see the advertisement affect the purchase decision rhythm", and in dynamic threshold control, traditional solutions use static empirical values or single-dimensional indicators, which are difficult to adapt to market sudden fluctuations, often resulting in misjudgment expansion or defensive delay.

[0047] Embodiment one

[0048] A multi-modal learning-based marketing intelligent decision system, in the specific implementation process, as shown in Figure 1 The multi-modal learning-based marketing intelligent decision system module structure diagram is shown, which includes:

[0049] Multi-modal data analysis module 100: simultaneously access social media text stream, short video advertising stream and transaction pulse stream, and extract product attribute vector from social media text stream, quality evaluation vector and quality fluctuation value from short video advertising stream, and decision rhythm vector and transaction time data set from transaction pulse stream.

[0050] Specifically, in the multi-modal data analysis module 100, the extraction step of the product attribute vector includes:

[0051] Determine the product function dimension initialization of all dimensions of the product function aggregator based on the pre-constructed product function keyword tree;

[0052] Based on the pre-constructed product function keyword dictionary, match the product function keywords of the current text in the social media text stream, and assign the current text to the corresponding product function aggregator based on the matched product function keywords;

[0053] Identify the sentiment words, degree adverbs and negative words associated with the product function keywords in the current text in the product function aggregator to construct a triple;

[0054] Calculate the function attribute intensity based on the triple, and obtain the average function attribute intensity value by weighted average of all function attribute intensities in the same product function aggregator;

[0055] Combine the average function attribute intensity values in different product function aggregators into a product attribute vector according to the arrangement order of the product function dimension.

[0056] Specifically, in the multi-modal data analysis module 100, it also includes forced conversion of traditional Chinese to simplified Chinese for the social media text stream before extracting the product attribute vector.

[0057] Specifically, in the multi-modal data analysis module 100, the extraction step of the quality evaluation vector and the quality fluctuation value includes:

[0058] Extract the advertising click-through rate, video three-second skip rate and complete play rate of each short video advertisement in the short video advertising stream;

[0059] Calculate the advertising quality score based on the advertising click-through rate, video three-second skip rate and complete play rate;

[0060] The advertisement quality scores of all short video advertisements are weighted and fused to obtain an advertisement quality evaluation total score, and meanwhile, a quality fluctuation value is calculated based on the maximum value and the minimum value in the advertisement quality scores of all short video advertisements, and the advertisement quality evaluation total score is converted into a single-element quality evaluation vector.

[0061] Specifically, in the multi-modal data analysis module 100, the extraction steps of the decision rhythm vector and the transaction time data set include:

[0062] The transaction decision time interval of each user in the transaction pulse stream is calculated, and the transaction decision type of each user is determined according to the preset decision time threshold of different industries, wherein the transaction decision type includes impulsive type, rational type and long cycle type;

[0063] The transaction decision time intervals of the users of the impulsive type are combined into an impulsive transaction time interval table, the transaction decision time intervals of the users of the rational type are combined into a rational transaction time interval table, and the transaction decision time intervals of the users of the long cycle type are combined into a long cycle transaction time interval table;

[0064] The number proportion of each transaction decision type is calculated, and the calculated impulsive number proportion, rational number proportion and long cycle number proportion are sequentially combined into a decision rhythm vector and output;

[0065] The impulsive transaction time interval table, the rational transaction time interval table and the long cycle transaction time interval table are combined into a transaction time data set and output.

[0066] In the implementation process, in the multi-modal data analysis module 100 of the marketing intelligent decision system, first, synchronize access to three types of heterogeneous data sources: social media text stream, short video advertisement stream, and transaction pulse stream. For the social media text stream, initialize the aggregator of the product function dimension based on the pre-built product function keyword tree. Match the keywords in the text with the product function keyword dictionary and assign them to the corresponding aggregator. The product function aggregator is a data structure allocated in memory for each predefined product function dimension. Examples of predefined product function dimensions include but are not limited to "battery life", "camera function", and "screen display". These dimensions are used to aggregate and calculate user feedback intensity in real time. The product function dimension is determined by the pre-built product function keyword tree, which defines the core function classification of the product and its hierarchical relationship. Based on the pre-built product function keyword dictionary, which is derived from the leaf nodes of the product function keyword tree, match the product function keywords contained in the current text in the social media text stream in real time. According to the matching result, assign the current text to its corresponding product function aggregator. In the product function aggregator, identify the sentiment words associated with the product function keywords for the current text, including but not limited to "good", "bad", degree adverbs, including but not limited to "very", "comparatively", and negative words, including but not limited to "not" and "no". Build a triple of sentiment words, degree adverbs, and negative words, such as "waterproof, very, no negative". Calculate the sentiment intensity value of the triple. The weighting coefficients of degree adverbs are 1.3 for non, 0.7 for comparative, and negative words are negative. Weighted average the sentiment intensity values of all texts in the same aggregator according to time decay, such as 1.5 for 24 hours, 1.2 for 6 hours, and 0.8 for more than 6 hours. Obtain the average intensity value of each function dimension and combine it into a product attribute vector in dimension order. At the same time, perform mandatory conversion from traditional Chinese to simplified Chinese to eliminate dialect interference. For the short video advertisement stream, extract the click-through rate, three-second skip rate, and complete playback rate of each advertisement in real time. Weighted fusion is performed through pre-set weight values to obtain the advertisement quality score.2 Obtain the advertisement quality score of a single advertisement, weight and integrate the advertisement quality scores of all advertisements to obtain an advertisement quality evaluation total score, encapsulate the scalar value of the advertisement quality evaluation total score as a 1-dimensional single-element quality evaluation vector, and calculate a quality fluctuation value according to the difference between the maximum and minimum values of the score; for the transaction pulse stream, calculate the difference between the product first contact timestamp and the transaction payment timestamp as the decision-making time interval, classify according to industry thresholds, for example, less than 2 hours for the beauty category is impulsive, 2 to 6 hours is rational, and more than 6 hours is long cycle, when the interval is equal to the threshold, it is classified as long cycle, and build an impulsive, rational, and long cycle transaction time interval table to form a transaction time dataset, and calculate the impulsive, rational, and long cycle person proportion, respectively, and combine the three scalar values into a decision rhythm vector in order to output, which directly reflects the decision type distribution of the current user group, and is used to represent the overall decision rhythm of the market, for example, a high proportion of impulsive type means a large corresponding value of the vector, indicating that the market decision rhythm is fast.

[0067] The cross-modal feature fusion module 200: based on the product attribute vector and the decision rhythm vector, the attribute emergency index is calculated by element-by-element multiplication, based on the quality evaluation vector and the decision rhythm vector, the advertisement timeliness coefficient is generated by dot product operation, and based on the product attribute vector and the quality evaluation vector, the strategy matching degree is generated by vector module multiplication.

[0068] In the specific implementation process, first, the product attribute vector, the quality evaluation vector, and the decision rhythm vector are subjected to format standardization processing, since the dimensions of the three are different, they need to be converted into a format that can be subjected to algebraic operation, specifically, the single-element quality evaluation vector is expanded into a vector with the same dimension as the product attribute vector, and each element value of the vector is the advertisement quality evaluation total score; the decision rhythm vector is regarded as a 3-dimensional vector.

[0069] Then a triple fusion operation is performed, including attribute emergency index calculation, multiplying the product attribute vector with the "impulsive proportion" component in the decision rhythm vector element by element, and the multiplication result is a new vector, and each element value of the new vector is the product of the function attribute heat and the impulsive user proportion. The multiplication result quantifies the degree to which the positive market feedback for the product function comes from the user group with the fastest decision rhythm and the most impulsive, and the higher the value, the more urgent the market response triggered by the function attribute. The advertisement timeliness coefficient calculation is to perform a dot product operation on the quality evaluation vector and the "rational proportion" component in the decision rhythm vector, and the dot product result is a scalar, and the value of the scalar is the product of the advertisement quality score and the rational proportion. The value of the scalar represents the degree to which high-quality advertisement content matches the user group that is cautious in decision-making and needs rational persuasion, and a high coefficient indicates that the advertisement is timely and effective in influencing rational users. The strategic matching degree calculation calculates the product of the module length of the product attribute vector and the module length of the quality evaluation vector, and the product is a scalar, which measures the coordination level between the "overall market appeal of the product" and the "overall quality of the advertisement". A high matching degree indicates that the product force and the advertisement effect are synchronized and good. Finally, the output results are subjected to dynamic constraints: the attribute emergency index value is truncated to the [-5, 5] interval to prevent overflow, the advertisement timeliness coefficient is compressed to the (-1, 1) range through the tanh function to ensure comparability, and the strategic matching degree retains the original value but marks the threshold value event, that is, when the strategic matching degree exceeds the preset matching degree threshold, an alarm is triggered. All operation results are written into the fusion log in real time for audit tracing and provide data basis for subsequent modules.

[0070] The feature signal matrix generation module 300 combines the attribute emergency index, the advertisement timeliness coefficient, and the strategic matching degree into the current feature signal matrix, and extracts the main eigenvalue and the secondary eigenvalue of the current feature signal matrix.

[0071] Specifically, in the feature signal matrix generation module 300, the calculation steps of the main eigenvalue and the secondary eigenvalue include:

[0072] Calculate the covariance matrix of the current feature signal matrix.

[0073] Perform eigenvalue decomposition on the covariance matrix to obtain a plurality of eigenvalues, take the eigenvalue with the largest absolute value as the main eigenvalue, and take the eigenvalue with the smallest absolute value as the secondary eigenvalue.

[0074] In the implementation process, firstly, three key indicator attributes emergency index output from the cross-modal feature fusion module 200 are received, reflecting the synergistic emergency degree of product attributes and user decision rhythm, the advertisement timeliness coefficient representing the dynamic correlation of advertisement quality and decision timeliness, and the strategic matching degree measuring the consistency of product attributes and advertisement quality strategy. The three scalar indicators are combined into the current feature signal matrix in a fixed order; then the covariance matrix of the matrix is calculated to capture the fluctuation correlation between indicators; then the covariance matrix is decomposed to obtain all eigenvalues, the core is to apply the principal component analysis, a well-known theory in the field of data analysis and machine learning. The largest eigenvalue of the covariance matrix, i.e. the principal eigenvalue, represents the direction of the largest variance in the multi-modal fusion feature signal, and its numerical size quantifies the trend and intensity of the consistency of the market in all dimensions. This conforms to the market trend consistency principle and opportunity window theory in marketing, i.e. when multiple key indicators simultaneously and dramatically point to a positive direction, it indicates that a high- confidence market expansion opportunity is emerging, so it is explained as the system expansion motive strength. Conversely, the smallest eigenvalue, i.e. the secondary eigenvalue, represents the direction of the smallest variance or noise in the signal, and its small numerical value indicates that the system has weak but critical instability or vulnerability in a certain dimension, which conforms to the system risk management theory and the bucket effect, i.e. the overall risk of the system is often indicated by the weakest link or the abnormal signal that has not been fully captured, so it is explained as the system vulnerability. Through this PCA-based interpretation framework, the principal and secondary eigenvalues successfully convert mathematical abstraction into decision indicators with clear marketing implications and are output in real time to the downstream module.

[0075] The double-threshold generation module 400 calculates the expansion threshold based on the product attribute vector and the transaction time data set, and calculates the defense threshold based on the quality fluctuation value, the current feature signal matrix and the historical feature signal matrix.

[0076] Specifically, in the double-threshold generation module 400, the calculation steps of the expansion threshold include:

[0077] Extract the impulsive transaction time interval table in the transaction time data set and calculate the arithmetic mean time efficiency;

[0078] Based on the product attribute vector, the maximum functional attribute intensity value in the product attribute vector is obtained;

[0079] The arithmetic mean time efficiency, the maximum functional attribute intensity value and the preset industry expansion coefficient are multiplied to obtain the expansion threshold.

[0080] Specifically, in the double-threshold generation module 400, the calculation steps of the defense threshold include:

[0081] Calculate the eigenvalue variance of the current feature signal matrix;

[0082] calculate a historical sub-eigenvalue based on the historical characteristic signal matrix, and count a number of times that the historical sub-eigenvalue is less than a preset sub-eigenvalue threshold to obtain a risk number value, and take a reciprocal of the risk number value as a historical risk index;

[0083] multiply the reciprocal of the quality fluctuation value by the historical risk index, divide the result by the eigenvalue variance to obtain a defense threshold.

[0084] In the implementation process, first extract the impulsive transaction time interval table in the transaction time data set, and calculate its reciprocal average value as the arithmetic average time efficiency, that is, the number of transactions per unit time, the higher the efficiency, the higher the value. This value reflects the conversion speed of the most active user group in the market, and the maximum functional attribute intensity value is obtained from the product attribute vector, which represents the current most popular product function point that can attract users. Multiply the arithmetic average time efficiency, the maximum functional attribute intensity value and the preset industry expansion coefficient to obtain the expansion threshold, wherein the industry expansion coefficient is an empirical constant based on historical data or industry benchmark to adjust the threshold sensitivity of different industries. For example, according to the product category, for example, take 0.85 for the beauty category and 0.78 for the 3C category. The expansion threshold aims to define a critical point of market opportunity. This calculation is based on a reasonable marketing assumption: when (market conversion efficiency) × (product maximum attraction) × (industry adjustment factor) reaches a certain level, it is considered that there is a clear expansion opportunity. The product form comprehensively considers market speed, product power and industry characteristics. The higher the value, the stronger the required expansion evidence. Here, the arithmetic average time efficiency, the maximum functional attribute intensity value and the preset industry expansion coefficient correspond to the market conversion efficiency, the product maximum attraction and the industry adjustment factor respectively. Then calculate the eigenvalue variance of the current feature signal matrix, and based on the historical feature signal matrix, count the number of times that the historical sub-eigenvalue is less than the preset sub-eigenvalue threshold, for example, the sub-eigenvalue threshold is 0.3. Take the reciprocal of this number as the historical risk index. Finally, multiply the reciprocal of the quality fluctuation value, that is, the higher the advertisement quality stability, the higher the value, by the historical risk index, and then divide it by the eigenvalue variance to obtain the defense threshold. When the advertisement quality fluctuates or the historical risk frequency increases, the defense threshold decreases, and when the system state fluctuates violently, the defense threshold increases. The core of the defense threshold is to build a risk perception system that can dynamically evolve with the market environment. The reciprocal of the quality fluctuation value reflects the brand asset theory and the signal theory. High and stable advertisement quality is a strong signal of trust that the brand transmits to the market. The reciprocal directly quantifies the accumulation degree of this trust capital. The higher the stability, the more "trust reserves" it has to resist risks. The historical risk index is rooted in the organizational learning theory and the crisis warning theory. The system learns the risk patterns of the market by digging into the frequency of system vulnerability outbreaks in historical data. The higher the frequency, the lower the historical risk index, indicating that the system is in a risk environment that must be continuously learned. A more sensitive defense threshold must be set. The eigenvalue variance reflects the market effectiveness theory. A high variance indicates that the market state is complex and variable, and the consensus is low. The signal is chaotic. At this time, the defense threshold should be increased to avoid overreaction to noise. Conversely, a low variance indicates that the market state is clear and stable. At this time, the defense threshold should be reduced to capture subtle risks.Finally, by multiplying the inverse of the quality fluctuation value representing the "trust reserve" with the historical risk index representing the "historical lesson", and dividing the product by the eigenvalue variance representing the "market chaos degree", the resulting defense threshold is a highly adaptive indicator that conforms to the concept of anti-fragility, enabling the system not only to resist risks, but also to learn and evolve from market fluctuations and historical experiences, thus achieving intelligent risk control.

[0085] The decision signal generation module 500 generates an expansion signal and an expansion strength based on the main eigenvalue and the expansion threshold, and generates a defense signal and a defense strength based on the secondary eigenvalue and the defense threshold.

[0086] Specifically, in the decision signal generation module 500, the generation conditions of the expansion signal and the defense signal include:

[0087] When the main eigenvalue is greater than the expansion threshold, the expansion signal is generated, and when the secondary eigenvalue is less than the defense threshold, the defense signal is generated.

[0088] In the specific implementation process, the main eigenvalue and the secondary eigenvalue from the feature signal matrix generation module 300 are received in real time, and the expansion threshold and the defense threshold calculated by the double threshold generation module 400 are obtained; when the main eigenvalue exceeds the expansion threshold, a binary expansion signal is immediately generated, and the expansion strength is calculated, the calculation formula is the main eigenvalue divided by the expansion threshold, the result is limited in the interval [0, 5] to reflect the degree of opportunity exceeding the safety boundary, when the secondary eigenvalue is lower than the defense threshold, a binary defense signal is generated and the defense strength is calculated, the calculation formula is the secondary eigenvalue divided by the defense threshold, after logarithmic compression, it is mapped to the interval [0, 10] to quantify the risk level; finally, the signal with the expansion signal and the expansion strength and the defense signal and the defense strength is output for use by the downstream decision instruction generation module 600.

[0089] The decision instruction generation module 600 inputs the expansion signal, the expansion strength, and the defense signal, the defense strength into the pulse decision engine, and maps them to platform executable decision instructions through a pre-set rule base.

[0090] Specifically, in the decision instruction generation module 600, when the defense strength is greater than 1.5 times the expansion strength and less than 2 times the expansion strength, the defense instruction is preferentially executed, and when the defense strength is greater than or equal to 2 times the expansion strength, the defense instruction is delayed.

[0091] In the implementation process, the decision instruction generation module 600 converts the input expansion signal, expansion strength, defense signal and defense strength into platform executable decision instructions through the pulse decision engine, the core pulse decision engine of which adopts a three-layer decision tree structure: the first layer is a signal priority arbitrator, which triggers the defense instruction to execute the channel preferentially according to the preset priority decision rule, that is, when the defense strength is greater than 1.5 times and less than 2 times of the expansion strength, the defense instruction is triggered to execute the channel preferentially, and when the defense strength is greater than or equal to 2 times of the expansion strength, the delay execution queue is activated, for example, a 30-minute countdown is started and the defense strength is recalculated every 2 minutes, and if the defense strength deteriorates by more than 10% during the period, the defense is executed immediately; the second layer is a rule matching matrix, which maps the signal combination to 132 preset scenes, for example, the expansion signal plus the expansion strength plus the defense signal plus the defense strength is mapped to scene 47, and dynamic compilation is realized through a decision tree with weighted labels, for example, when scene 47 is matched, the instruction of “reduce high-priced advertisement budget by 20% and start medium-risk area promotion” is generated; the third layer is an instruction executor, which converts the abstract instruction into a specific platform API call, and finally realizes the intelligent decision of market marketing based on multi-modal learning,

[0092] The working principle of the market marketing intelligent decision system based on multi-modal learning provided by the application is as follows:

[0093] Firstly, the multi-modal data analysis module 100 processes three source heterogeneous data in real time: product attribute vectors are extracted from social media text streams; single element quality evaluation vectors and quality fluctuation values reflecting the stability fluctuation of the advertisement are generated from short video advertisement streams; decision rhythm vectors and transaction time data sets are output from transaction pulse streams. Then, the cross-modal feature fusion module 200 realizes feature interaction through differential algebraic operation: the attribute emergency index is generated by element-by-element multiplication of the product attribute vector and the decision rhythm vector, the advertisement timeliness coefficient is output by dot product operation of the quality evaluation vector and the decision rhythm vector, and the strategy matching degree is generated by vector module multiplication of the product attribute vector and the quality evaluation vector.
