Text classification is one of the important areas in natural language processing. The classification problem has been widely studied in data extraction, automated learning, database, and information retrieval with applications in many diverse fields, such as target marketing, medical diagnosis, newsgroup filtering, document organization, topic identification, . For example, in areas such as Computer Vision, there is a strong consensus on a general way of designing models, neural networks, and other approved methodologies. Otherwise, the classification of the text still lacks this general approach in many areas. In this paper, we aim to provide a comprehensive survey of a variety of methodologies and algorithms used to classify texts and their improvements. We will focus on the main general approaches to text classification algorithms and their usage cases.
