| Text classification: Text classification in Artificial Intelligence is the process of categorizing or labeling text documents into predefined classes or categories based on their content, enabling automated analysis and organization of textual data. Fields of application are spam filtering, sentiment analysis, topic modeling, intent detection, question answering. See also Spam, Question answering, Artificial Intelligence._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

AI Research on Text Classification - Dictionary of Arguments
Norvig I 865 Text Classification/text categorization/AI Research/Norvig/Russell: (…) given a text of some kind, decide which of a predefined set of classes it belongs to. Language identification and genre classification are examples of text classification, as is sentiment analysis (classifying a movie or product review as positive or negative) and spam detection (classifying an email message as spam or not-spam). >Spam/AI Research. Norvig I 884 Manning and Schütze (1999)(1) and Sebastiani (2002)(2) survey text-classification techniques. Joachims (2001)(3) uses statistical learning theory and support vector machines to give a theoretical analysis of when classification will be successful. Apté et al. (1994)(4) report an accuracy of 96% in classifying Reuters news articles into the “Earnings” category. Koller and Sahami (1997)(5) report accuracy up to 95% with a naive Bayes classifier, and up to 98.6% with a Bayes classifier that accounts for some dependencies among features. Lewis (1998)(6) surveys forty years of application of naive Bayes techniques to text classification and retrieval. Schapire and Singer (2000)(7) show that simple linear classifiers can often achieve accuracy almost as good as more complex models and are more efficient to evaluate. Nigam et al. (2000)(8) show how to use the EM algorithm to label unlabeled documents, thus learning a better classification model. Witten et al. (1999)(9) describe compression algorithms for classification, and show the deep connection between the LZW compression algorithm and maximum-entropy language models. 1. Manning, C. and Schütze, H.
