There is trend to learn Data Science using R Training in Mumbai/ With this blog our instructor has given fair idea, about Text Mining in Data Science training. We have always encouraged our students to Learn R Practically.

“Text mining is element in data science which allows us to highlight the most frequently used keywords in a given data.

It is also referred as text cloud or tag cloud, which is use for visual representation of text data. Word cloud Size is related with frequency if frequency is more, then word size will be bigger otherwise word size will be smaller size.

Creating word clouds is very simple in R if you know the Procedure or steps to execute. The text mining (tm) and the word cloud generator (word cloud) packages are available in R for helping us to analyze texts and to quickly visualize the keywords as a word cloud.

Why industry prefers word Cloud to present data?
