He did it again! Neil McGuigan of Vancouver Data Blog has posted series of videos earlier, the first one about text mining and the second one about web scraping and web mining with RapidMiner.

Neil's new video series will again help a lot of RapidMiner users including beginners as well as more experienced analysts since it covers one of the most important aspects of data analysis: loading and transforming the data into a format which is most suitable for analysis. It is widely known that this type of data preparation easily takes up to 90% of the total efforts you put into analysis.

Neil has produced four again really great videos covering some of the most important aspects of ETL (Extract, Transform, and Load) and how this can be done with RapidMiner. Here we go:

• RapidMiner ETL: Combining Data Sets
• RapidMiner ETL: Sampling, Selecting Rows, Attributes
• RapidMiner ETL: Normalizing, Discretizing, Recoding
• RapidMiner ETL: Transforming Attributes with Functions
  

Here is the first video, please find the rest in Neils blog (see links above):

Please visit the Vancouver Data Blog for more information and please leave some comments for Neil - he will appreciate your thanks!

We are sure that we speak for the many users out there when we thank you, Neil, for putting these efforts into producing those videos - they are certainly helping a lot!
