1.The data collection is actually done by a Web crawler continuously checking the tweets on the Web based twitter site. Which type of Web mining is it called? What benefits can this Web mining bring to this specific scenario?

2.Once the text comments are fetched from the twitter site, text mining techniques are applied to structure the comments and extract knowledge. In this step, a term-by-document (tweet) matrix will be created. According to the tweets shown in the table, please design such a matrix and fill in the values (You can design the matrix in a separate file and attach it) . Explain why you design it like that (e.g., in terms of the words included, best representation)?
