同学你好,原版书上对text analytics and NLP的描述如下:
Text analytics involves the use of computer programs to analyze and derive meaning typically from large, unstructured text- or voice-based datasets, such as company filings, written reports, quarterly earnings calls, social media, email, internet postings, and surveys. Text analytics includes using computer programs to perform automated infor- mation retrieval from different, unrelated sources to aid the decision-making process. More analytical usage includes lexical analysis, or the analysis of word frequency in a document and pattern recognition based on key words and phrases. Text analytics could be used in predictive analysis to help identify indicators of future performance, such as consumer sentiment.即文本分析主要就是通过计算机程序从海量的非结构化信息中训练提取有用的信息,目前Natural language processing (NLP) 技术已经非常成熟了
