[0047] Specifically, the main task of the data collection module is to collect extensive text data in the field of power information and communication. This data can come from various documents, reports, technical manuals, specifications, news articles, forum discussions, etc. in the power industry. To ensure the diversity and comprehensiveness of the data, the following measures can be taken: Multi-channel collection: Collect data from multiple channels such as the official website of the power company, industry forums, technical communities, academic databases, etc.; Regular update: With the continuous development of power information and communication technology and the introduction of new policies, the data set needs to be updated regularly to ensure the timeliness and accuracy of the model; Data deduplication: During the collection process, use data deduplication technology to avoid the impact of duplicate data on model training.

Based on the evaluation results, the model can be fine-tuned or retrained to further improve the accuracy and generalization ability of the model in the field of power information communication.
