An investigation using natural language processing (NLP) involves analyzing and understanding human language text data. This can include tasks such as extracting information from documents, classifying text into different categories, or generating text based on specific inputs. For example, an investigation could use NLP to analyze patient medical records and identify patterns that help predict health outcomes. Another investigation could use NLP to extract key concepts from customer feedback and identify areas for product improvement. NLP techniques enable computers to perform these tasks by understanding the meaning and structure of human language, which is essential for extracting meaningful insights from text data.
