Search a word list in a database
I'm trying to find out how to search a word list in a database with RapidMiner for some time now, but cannot find a solution. I will be extremely thankful if somebody can help me.
I'm working with a database consisting of 25.000 rows with relative large amount of text data. I have extracted a word list with the top 10% of the most frequent words in this database. The total count of unique words is around 35.000. The most frequent (over 100) words are around 3500. I need to find out in which rows I can find each word of the most frequent list. In other words I need to create a binary vector matrix with 25.000 rows and 3500 columns. Can I do that with RapidMiner?
Thank you very much in advance!
