text mining 笔记
发布时间:2024-11-10        浏览次数:0        返回列表
Text mining, also known as text analytics, is the process of extracting useful information from unstructured or semi-structured text data. This involves using various natural language processing (NLP) techniques to analyze and understand the content of the text. Text mining can be applied to a wide range of text data sources, including social media posts, customer reviews, news articles, and scientific papers.

The primary goal of text mining is to uncover insights and patterns that can be used to inform decision-making and improve business outcomes. For example, a company may use text mining to analyze customer feedback and identify common themes and issues that need to be addressed. A healthcare organization may use text mining to analyze patient records and identify patterns in disease diagnosis and treatment. Text mining involves several steps, including data collection, preprocessing, analysis, and visualization. The data is usually first cleaned and preprocessed to remove noise and irrelevant information. NLP techniques are then used to tokenize the text, identify parts of speech, and extract entities and sentiment. The resulting data is analyzed using statistical and machine learning techniques to uncover patterns and relationships.
