Visualizing the document pre-processing effects in text mining process
(2018-01-01)
Text mining is an important step to categorize textual data by using data mining techniques. As most obtained textual data is unstructured, it needs to be processed before applying mining algorithms – that process is known ...
Analysis of document pre-processing effects in text and opinion mining
(2018-04-20)
Typically, textual information is available as unstructured data, which require processing so that data mining algorithms can handle such data; this processing is known as the pre-processing step in the overall text mining ...
