In the prior art, although individual studies have attempted to introduce natural language processing technology, most are limited to keyword matching or simple classification and have not been deeply integrated with the three-level coding framework of grounded theory. In addition, existing automated tools lack a dynamic optimization mechanism and cannot adapt to complex and changing text environments. Therefore, there is an urgent need for an intelligent coding scheme that combines deep semantic analysis and continuous learning. Summary of the Invention

[0049] The following further describes the present application in detail with reference to the accompanying drawings.

[0050] In one embodiment, as Figures 1 - 3 shown, the present application discloses a grounded theory coding optimization method assisted by a generative language model, which specifically includes the following steps:

[0051] S10: Receive the original text data, and convert the original text data into an initial corpus set after clause segmentation through a transcription and clause segmentation tool;

[0052] S20: Use a pre-trained generative language model to perform semantic analysis on the initial corpus set, extract text features, and generate a set of feature vectors;

[0053] S30: Based on the set of feature vectors, by calculating the similarity between the new text and the preset open coding, axial coding, and selective coding corpora, automatically classify the new text into the corresponding three-level coding categories, and output the automatic classification result;

[0054] S40: Manually review the automatic classification result, correct the coding items with low matching degree or ambiguity, and feedback the correction result to the generative language model to optimize the model parameters;

[0055] S50: Dynamically update the coding corpus and the text feature set according to the new data and the manual review result to achieve continuous optimization of the model.

[0056] In this embodiment, the original text data may be interview records, observation notes, etc. Use a transcription tool to convert speech or video data into text. The preset coding corpus includes open coding, axial coding, and selective coding.

[0057] Specifically, use a clause segmentation tool to split continuous text into independent sentences to form an initial corpus set. Use a pre-trained generative language model to deeply analyze the initial corpus set, understand the semantic content of the text, extract text features, and convert these features into a set of feature vectors. These feature vectors can represent the semantic information of the text. Based on the set of feature vectors, by calculating the similarity between the new text and the preset coding corpus, achieve automatic classification of the text, output the automatic classification result, and assign the text to the corresponding three-level coding category. Manually review the automatic classification result, correct the parts with low matching degree or ambiguity in the classification result, and feedback the correction result of the manual review to the generative language model to optimize the parameters of the model and improve the classification performance of the model. Over time, collect new data, and according to these new data and the results of the manual review, dynamically update the coding corpus and the text feature set. Through this iterative process, achieve continuous optimization of the model to better adapt to the changing data and coding requirements.

[0058] In one embodiment, step S20 specifically includes the steps of:

[0059] S21: Extract keywords and perform semantic association analysis on the text after clause segmentation;

[0060] S22: Generate a context representation of the text based on the attention mechanism;

[0061] S23: Combine the pre-trained word embedding technology to generate feature vectors with multi-dimensional semantic information.

[0062] In this embodiment, the keywords are usually nouns, verbs, and adjectives, which can represent the main content and core idea of the text. The attention mechanism is a commonly used technology in neural networks for emphasizing certain important parts in the input sequence. The word embedding technology can be Word2Vec, GloVe, or BERT, etc. These technologies can map words to vectors in a high-dimensional space, where the distance between vectors can reflect the semantic similarity between words.

[0063] Specifically, extract keywords from the text after clause splitting, identify the most important words in the text, conduct semantic association analysis by analyzing the grammatical structure, co-occurrence relationship, and semantic network between words, understand the relationship between keywords and their semantic roles in the sentence, use the attention mechanism to generate a context representation of the text. The attention mechanism can help the model focus on the part of the text most relevant to the current task, thereby generating a representation that can reflect the context of the entire sentence or paragraph. Combine the pre-trained word embedding technology to generate feature vectors with multi-dimensional semantic information. These feature vectors not only contain the semantic information of words but may also contain the grammatical information and context information of words, thus being able to represent the text content more comprehensively.

[0064] In one embodiment, step S30 specifically includes the steps:

[0065] S31: Calculate the similarity between the new text and the open coding corpus through the cosine similarity algorithm to determine the initial coding category;

[0066] S32: Based on the initial coding category, combine the semantic clustering algorithm to further classify the new text into the axial coding;

[0067] S33: Through dependency syntactic analysis and topic modeling, map the axial coding result to the selective coding category and output the automatic classification result.

[0068] In this embodiment, the cosine similarity algorithm is a commonly used method for measuring text similarity. It determines the similarity between two vectors by measuring the degree of similarity in their directions; the semantic clustering algorithm can group texts into different categories according to their semantic content; the axial coding is a further abstraction and induction of the results of open coding, aiming to find the main themes and patterns in the data; the dependency syntactic analysis is used to analyze the dependency relationships between words in a sentence, which helps to understand the structure and deep meaning of the text. Topic modeling is an unsupervised learning method that can identify the topic distribution in a large-scale text collection; selective coding is a process of further refining and selecting core categories on the basis of axial coding to form a theoretical framework.

[0069] Specifically, the cosine similarity between the feature vector of the new text and the center vectors of each category in the open coding corpus is calculated by the cosine similarity algorithm. According to the similarity score, the initial coding category of the new text is determined, and the category with the highest similarity will be regarded as the initial classification of the new text. Using the initial coding category determined in step S31, the semantic clustering algorithm is used to further analyze the new text and classify it into a more refined axial coding category. The results of the axial coding are mapped to the selective coding category through dependency syntactic analysis and topic modeling, and the final automatic classification result is output, which classifies the new text into the existing coding categories or creates new coding categories as needed.

[0070] In one embodiment, step S50 specifically includes the steps of:

[0071] S51: Based on the incremental learning algorithm, the new data is input into the generative language model for incremental training;

[0072] S52: Through the adaptive weight adjustment strategy, balance the feature weights of the historical data and the new data;

[0073] S53: Regularly perform redundancy removal processing on the coding corpus and retain the feature entries with high confidence.

[0074] In this embodiment, the incremental learning algorithm allows the model to be updated when new data is received, rather than retraining from scratch; the new data is input into the generative language model, and this data can be new text samples or the latest coding information.

[0075] Specifically, based on the incremental learning algorithm, new data is input into the generative language model, and the model will use this new data to perform incremental training on itself to adapt to the changes in the data distribution and improve the processing ability for new data. Since historical data may still contain valuable information, while new data may reflect the latest trends or changes, different emphases need to be given. The adaptive weight adjustment strategy is used to dynamically adjust the feature weights of historical data and new data during the model training process. Through this strategy, the model can better balance the importance of old and new data, avoiding overfitting to historical data or ignoring key information in new data. As time goes by, the encoded corpus may accumulate a large amount of data, which may contain duplicate or similar feature entries. During the redundancy removal process, high-confidence feature entries, that is, those considered reliable and important in the model, can be retained, which can be achieved by setting a confidence threshold, and only feature entries exceeding this threshold will be retained.

[0076] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution is prior or subsequent. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of this application.
