Detailed Description
The following is a preferred embodiment of the present invention and a technical solution of the present invention is further described with reference to the accompanying drawings, but the present invention is not limited to this embodiment.
The invention provides a method for constructing a low-code data computing platform of a agile analysis scene.
Specifically, the invention discloses a system for constructing a low-code data computing platform for a social network agility analysis scene, which comprises a data source definition flow and a data source processing flow for each data source:
specifically, the data source definition flow defines social platform data source data, and includes 4 modules:
the data format definition module is used for defining the data formats of the heterogeneous social platform, including but not limited to data formats such as text, pictures and videos, and carrying out field binding on a plurality of specific relations (praise, forwarding and comment) and a plurality of attributes (account id and user nickname) of the social platform, wherein other fields define data types and meanings by users;
an example format is as follows:
the system definition field is a minimum set of basic attributes of the social platform data, and comprises a minimum information set required for constructing a correlation map:
text_fields: text fields are defined. In the example only one content field is included, the type of which is "text".
image_fields: a picture field is defined. In the example only one image url field is included, the type of which is "image".
video_fields: a video field is defined. In the example only one video_url field is included, the type of which is "video".
relationship_fields: relationship fields are defined, including praise, comment and share. In the example, the like, comment and share fields are defined, respectively, and their types are "relation". These relationship fields may be bound to other related fields (e.g., account_id and user_name).
User-defined fields can be used as additional information for data analysis to enhance the authenticity and reliability of the analysis results:
user defined fields: user-defined fields are defined. Two custom fields, custom_field1 and custom_field2, of the types "text" and "number" respectively, are defined in the example. The user can define more custom fields as required.
After the data definition is adopted, the platform can perform unified access on data of multiple sources, so that the data sources are fully decoupled from the subsequent service, and the complex analysis service is enabled.
And the preprocessing flow definition module is used for defining the flow processing flow of the data source data preprocessing module by arranging a plurality of predefined data preprocessing functions or adding a user-defined preprocessing function by a user. Specific aspects include, but are not limited to, data cleaning, deduplication, filtering, normalization, etc. to ensure accuracy and efficiency of subsequent data processing and analysis. The configuration examples are as follows:
a pipeline is an array of pre-processing streams defining a series of pre-processing functions and their parameters.
Each preprocessing function is represented by an object, which contains two fields, name and params. The name field indicates the name of the preprocessing function, such as "dataCleaning", "dataDeduplicatio n", "dataFiltering". The params field is an object for setting parameters of the preprocessing function. The specific parameters are dependent on each function.
In an example, the "dataclean" function has two parameters: removetopwords and remov ePunctuation, determine whether to remove stop words and punctuation.
The "dataDegussation" function has one parameter: keyField, a key field designated for deduplication.
The "dataFiltering" function has one parameter: the filter condition is set, and a filter condition is set, for example, data with a praise number greater than 1000 is screened out.
And the analysis task scheduling module is used for selecting different analysis services according to different analysis requirements based on the analysis services provided by the system analysis service center, and combining and scheduling the results. The module supports the orchestration of a variety of analysis tasks and operates in an out-of-service manner. These analysis service algorithms may be categorized according to different classifications, including but not limited to machine learning, deep learning, and user-defined algorithms.
For the machine learning algorithm, a support vector machine (Support Vector Machine), random Forest (Random Forest), logistic regression (Logistic Regression), K nearest neighbor algorithm (K-Nearest Neighbors), principal component analysis (Principal Component Analysis), adaBoost algorithm, XGBoost algorithm and the like are supported.
For the deep learning algorithm, a convolutional neural network (Convolutional Neural Networ k), a cyclic neural network (Recurrent Neural Network), a Long Short-Term Memory network (Long Short-Term Memory), a bidirectional cyclic neural network (Bidirectional Recurrent Neural Network), a generation countermeasure network (Generative Adversarial Network), a Transformers, and a deep reinforcement learning algorithm are supported
For the user-defined algorithm, the user can develop the algorithm for analysis according to the own requirements and data characteristics. These algorithms may be based on traditional statistical methods, domain-specific knowledge models, or other custom analysis methods.
The analysis task orchestration module supports the user to select different algorithms and configure their parameters to meet specific analysis requirements. The user can flexibly select a proper algorithm according to the data characteristics, the problem types and the service scene, and combine and arrange a plurality of algorithm results to obtain a required analysis result. Therefore, multi-angle and multi-dimensional analysis of the data can be realized, and more comprehensive and accurate analysis service is provided for the user. The configuration examples are as follows:
analysis tasks are arrays of analysis tasks defining a series of analysis tasks and their algorithms and parameters. Each analysis task is represented by an object, which contains name, algorithm and params fields.
The name field is the name of the analysis task, such as "sendmentanalysis", "topicClassi fication".
The algorithm field specifies the algorithm class used, such as "mapping learning", "deep learning", or other user-defined algorithms.
The params field is an object for setting parameters of an analysis task. The specific parameters are per algorithm.
In an example, the "sendmentanalysis" analysis task uses a machine learning algorithm to analyze emotion, which analyzes the "text" field and stores the results in the "sendent" field.
The "topicClassification" analysis task uses a deep learning algorithm to classify the topic, which analyzes the "text" field and stores the results in the "topic" field.
The "entityExtraction" analysis task uses natural language processing algorithms for entity extraction, which analyze the "text" field and store the results in the "entities" field.
The "networkAnalysis" analysis task uses a graph processing algorithm to perform social network analysis, which analyzes fields such as "accountds", "lists", "comments", "shares", and stores the results in the "networkMetrics" field.
According to the actual requirements you can customize the analysis tasks, algorithms and parameters according to this example and set the fields to be analyzed as needed.
The output result definition module: the format and content of the output results are defined according to the user's needs, including but not limited to statistics, charts, social association graphs, and the like. The module supports the definition of various output results, various data display modes and various data exposure modes so as to meet different business requirements. The configuration examples are as follows:
outputescents are arrays of output results, defining a series of output results and their types and fields. Each output result is represented by an object, which contains a type and corresponding fields.
the type field specifies the type of output result, such as "statistics", "chart" or "Association G graph".
In the example, the first type of output result is "statistics," which generates statistics and computes them through specified fields, here "send" and "topic.
The second type of output result is "character", which generates a histogram and uses the "topic" field as the X-axis and the "send" field as the Y-axis.
The third type of output result is "socialGraph", which generates a social association graph, and uses the "entries" field as node information and the "networkMetrics" field as link information.
According to the actual requirements you can customize the output result and its type and related fields according to this example.
Specifically, the data source processing flow runs the defined processing flow, and includes 5 modules:
and the data access module is used for: the module utilizes a registration callback mechanism to realize flexible access to the data sources in the form of a micro-service function, and accesses the social platform data of different sources into the system. The access module performs preliminary cleaning and formatting on the received data, and sends the data to the data preprocessing module for further processing;
and a data preprocessing module: the module takes stream computation as a main organization mode and carries out preprocessing on continuously added and unordered social platform data. Aiming at the newly added data characteristics, the rapid adaptation can be performed by adding a stream processing link. The pseudo code is as follows:
the social connection diagram construction module: the module decouples the data storage flow from the processing flow through the message subscription framework, constructs the data into a social association graph and stores the social association graph into a graph database. The method is beneficial to converting the social platform data into the graphical data, and facilitates subsequent data analysis and customized output;
and a data analysis module: the module is in the form of a service center (Serverless) to achieve high scalability of analysis capability. Various data analysis algorithms can be flexibly selected, and a preset low-code operator and a visualization component are provided, so that a user can conveniently customize and output data analysis results;
the above pseudocode defines an analysis module interface that all data analysis modules need to implement and provide an analysis method to execute specific data analysis logic. Two data analysis services, sentimentAnalysis and topicClassification, are then invoked, which respectively perform emotion analysis and topic classification on the data. Finally, in the combineAnalysis modules function, the different analysis modules are combined and their analysis methods are called sequentially to complete the data analysis. Different analysis modules can be created according to actual requirements and are transmitted into Co mbineAnalysisModules functions together with the original data for analysis. Finally, the system may process and output the analysis results.
And a customized output module: the module registers a corresponding data analysis module according to the analysis requirement of a user, and periodically collects corresponding analysis results to construct specific service output such as portraits and the like so as to enable downstream services. The output module also supports custom output formats and channels to meet the output requirements of different users.
The data source definition flow and the data source processing flow are associated and correspond to each other, the data format definition module configures the multi-source data access module, the processing flow definition module configures the data preprocessing module, the analysis task arrangement module configures the data analysis module, and the output result definition module configures the customized output module and configures an acceptance scheme of the downstream task.
The drag editing page provided by the control panel of the data source is edited and configured in a low-code mode, and a user does not need to perform detailed encoding operation on the data flow control.
For each newly built data source, the control panel creates a corresponding data source controller, and performs unified management on creation, inquiry, update and deletion of the data source. The data source controller can periodically send heartbeat signals to the control panel to report the state of the data source controller, so that the data source manager can take timely response measures to the controller disconnection condition.
After creation, the data source controller will inform the resource coordinator to allocate resources to the particular flow modules. Taking a preprocessing manager as an example, the resource coordinator searches for a proper free physical node in the cluster according to the default function number set in the preprocessing manager, and creates a preprocessing function on the physical node.
As seen in fig. 2 below, the resource data source a controller creates a preprocessing function 1 and a processing function m on physical node 1 and physical node n, respectively, after notifying the resource coordinator to create the functions. At the same time, there can be multiple processing functions on one physical node.
The capacity expansion function is designed to dynamically adjust the resources according to the load condition, so that the system can adapt to different workloads and improve the utilization efficiency of the resources.
When the resource utilization rate exceeds the threshold value, the threshold value can be set according to the actual situation or determined by tuning; if it is below the threshold, no expansion is required.
Calculating the number of instances requiring capacity expansion: num_samples=int (resource_use/thre shold) +1. And calculating the number of instances needing to be expanded according to the ratio of the resource utilization rate to the threshold value.
Limiting the calculated number of instances to not exceed a maximum number of instances: num_samples=min (num_samples, max_samples).
And returning the calculated number of examples to represent the number of the expansion needed. The code examples are as follows:
the capacity expansion function can be adjusted and modified according to actual conditions. The parameters such as the resource utilization rate threshold value, the maximum instance number and the like can be set according to the system requirements and actual conditions so as to meet the requirements and improve the system performance.
The created function can send a heartbeat signal to the subordinate manager at regular time, inform the function and the running state of the function running container, and perform expansion and contraction processing according to the load condition.
In particular, for the data analysis center, it can be understood that a group of normalized algorithm libraries organized in an out-of-service form can be deployed in another set of hardware device environment alone, because its computing power may depend on a dedicated device such as a graphics computing component. The data processing flow is coordinated with the service center station through a communication protocol, so that components can be fully decoupled, and the overall robustness and usability are improved;
FIG. 3 illustrates the overall analysis and computation flow of data after defining the data sources.
Step one: the data source a pushes the acquired message to the message queue either with a software-provided API or with a generic message queue SDK. The message can be pushed in a single data text format, and can also be pushed in a batch format.
Step two: the subordinate function instance of the data source A manager can regularly pull new data from the message queue, and after the topic of the message is modified, the subsequent function is reserved for processing. Finally, the whole preprocessing flow is executed in a sequential form.
Step three: after processing, the data waits for capturing the function instance of the social connection graph constructor in the message queue. The attribute vector embedding function normalizes attribute fields in the data according to a predefined type and converts the attribute fields into a vector form. After entering the database, the subsequent analysis module is reserved for use. The data is then organized in the form of a graph and stored in a graph database. The two provide data bottom layer support for subsequent analysis business.
Step four: and the data analysis manager can call the analysis algorithm provided by the corresponding data analysis center according to the configured index at regular intervals. The analysis tasks are generally divided into two types:
if the analysis index is of an independent type, i.e. does not need to rely on other data, but only on statistical values such as max, it directly updates the index of the corresponding node of the graph database after calculation.
If the analysis index depends on other data, if the whole graph needs to be walked, the addition of a new node can bring about the updating of other node indexes. Such computing tasks typically require a longer time to compute, which may trigger the computing task when the overall load of the cluster is low, timing or accumulating the same task to a counter threshold. When the database is updated, the database is locked, and the service is provided again after the update is completed.
Step five: the output manager will periodically rearrange the analysis index data in the form of configuration requirements and finally provide it to downstream applications, which are generally divided into two ways:
if the user configures the passive receiving mode, the output manager will sort the results regularly and send them to the message queue. Or calling a hook function configured by the user and sending the result to the corresponding address.
If the user configures an active receiving mode, the user can acquire an analysis result in the latest state by only setting a calling api provided by the system externally.
And repeatedly executing the first step to the fifth step.
