[0027] Working principle of the first embodiment: By extracting clinical value points from clinical trial development plans to formulate clinical trial design plans, clinical trial design plans can be automatically generated with comprehensive and accurate research and development directions, which improves the success rate of clinical trials and drug development, shortens the time of clinical trial development and reduces clinical trial costs; at the same time, through the AI training module combined with machine learning models and deep learning models, it has strong autonomous learning capabilities, and continuously corrects its own behavior through big data, thus having intelligent decision-making and intelligent operations capabilities, further improving the success rate of clinical trials and drug development.
[0028] For example 2, please refer to Figure 1-2, this embodiment 2 makes the following improvements on the basis of embodiment 1.

[0029] In order to ensure that the standard metadata of the clinical trial design plan is of high quality, complete and accurate, specifically, before obtaining the standard metadata of the clinical trial design plan, the basic elements of the clinical trial design plan are formulated; among which, the basic elements of the formulated clinical trial design plan include innovations in basic research and drug action mechanisms, precision treatment points, dynamic changes in treatment needs, improvements in drug safety, improvements in treatment experience and convenience, and patient needs.
[0030] The collection settings include project environment, project information, storage locations of various files and test data reading cycle. The project environment and project information are set according to the clinical trial project.

The BERT model is used to realize the word embedding function, and the BILSTM model and the CRF model construct a training neural network and constrain the output results.
[0032] The BERT model is an architecture that can be used for many downstream tasks, such as answering questions, classification, NER, etc. The working principle of the BERT model is the same as that of most Imagenet deep learning models. First, the BERT model is trained on a large corpus (Masked LM task), and then the model for our own task is fine-tuned by adding some extra layers at the end. The model can be classification, question answering, or NER, etc.; BiLSTM (Bidirectional Long Short-Term Memory Network) is a special recurrent neural network (RNN) that can process sequence data and maintain long-term memory. Unlike traditional RNN models, BiLSTM considers both past and future information, allowing the model to better capture contextual relationships in sequence data; Conditional Random Field (CRF) is a basic model in natural language processing, widely used in scenarios such as word segmentation, entity recognition, and part-of-speech tagging. With the popularity of deep learning, models such as BILSTM+CRF, BERT+CRF, TRANSFORMER+CRF, etc. have gradually appeared, and the effect has been significantly improved in these tagging scenarios.

The project environment and project information are set according to the clinical trial project. According to the set collection settings and the basic elements of the clinical trial design plan, a clinical trial design plan flow chart is established.

[0035] The deep learning model uses the CNN+FPN network structure for feature extraction, and then uses the RPN network structure to generate multiple table candidate areas, performs table classification, table boundary regression and table line segmentation prediction on each table candidate area, and finally obtains all lines of all wired tables and all lines of all wireless tables on the current image; the AI control module includes the ROBOT unit and the AI+RPA unit; the ROBOT unit is connected to the AI+RPA unit through an engine; the output end of the data preprocessing module is communicated with the ROBOT unit; the AI control module combines machine learning models and deep learning models, and has strong autonomous learning capabilities. Its OCR, NLP, speech recognition and other technologies enable the RPA unit to have cognitive capabilities, and can continuously correct its own behavior through big data, thereby having intelligent decision-making and intelligent operations capabilities.
[0036] The integration module is used to retrieve and integrate standard meta-training data to obtain a clinical trial design plan based on industry experience, domestic and international industry regulations, and the summarized "669" principle, namely the six major processes of clinical trials, the six major elements of clinical trial design, and the nine minor elements of clinical trial design. The six major processes of clinical trials include planning, design, execution, analysis, reporting, and interpretation.
[0037] The six major elements of clinical trial design include study population, intervention, control group, response variable, methods to reduce or assess bias, and statistical analysis; the nine minor elements of clinical trial design include study population, intervention, control group, response variable, methods to reduce or assess bias, statistical analysis, research purpose, research type, and data source.

By integrating the standard metadata of the clinical trial design plan, the clinical trial design plan is obtained. According to the clinical trial design plan, a clinical trial design plan database structure description file is obtained. According to the clinical trial design plan, a clinical trial design plan database is established according to the clinical trial design plan database structure description file, and the clinical trial design plan is stored in the clinical trial design plan database; and through the AI control module combined with the machine learning model and the deep learning model, it has a strong autonomous learning ability, can continuously correct its own behavior through big data, so as to have intelligent decision-making and intelligent operation capabilities, thereby improving the success rate of clinical trials and the success rate of drug development.
