Fig. 1From: Design and analysis of a general vector space model for data classification in Internet of ThingsGeneral flow chart of text classification algorithm. Text classification was divided into two stages. Step 1 represents the construction process of the classifier (including training set text, text preprocessing, multi-category feature selection, multi-category feature weighting). Step 2 represents the process of text categorization based on the classifier (including text to be classified, text preprocessing, feature selection of single text, feature weighting of single text) and gets the final classification resultsBack to article page
