Keyword-based Association Analysis: It collects sets of keywords or terms that often happen together and afterward discover the association relationship among them. Text mining (or more broadly information extraction) encompasses the automatic extraction of valuable information from text. Then the words need to be encoded as integers or floating point values for use as input to a machine learning algorithm, called feature extraction (or vectorization). The process of text mining involves various activities that assist in deriving information from unstructured text data. The mining process of text analytics to derive high-quality information from text is called text mining. This can include statistical algorithms, machine learning, text analytics, time series analysis and other areas of analytics. Algorithms are implemented as SQL functions and leverage the strengths of Oracle Database. The second method is to structure your text so that it can be used in machine learning models to predict future events.
