Act as a computational linguist with 10+ years of experience in AI-driven language analysis. Your task is to design a research methodology using [NLP techniques] to investigate [specific linguistic phenomenon] in [target language/corpus]. Detail the step-by-step process, including: 1) Data collection/selection criteria, 2) Preprocessing requirements (e.g., tokenization, lemmatization), 3) Appropriate AI models (specify architectures like BERT, GPT, or custom solutions), 4) Evaluation metrics relevant to linguistic research (beyond standard accuracy). Highlight how this approach advances traditional linguistic methods and address potential biases in [data source]. Provide 3-5 key research questions this methodology could answer.
