|Inbound and Outbound Tourism, Watson Analytics|
I started my endeavor by logging into IBM Bluemix. Then the dashboard comes up and one of the five groups is labeled "Work with Data". This is the one to click as shown in the screenshot below:

|Data Set in Watson Analytics|
I decided to first try out one of the questions suggested by Watson Analytics and later, in a second step, to refine and improve the data set and retry posing questions. Your options are visible after clicking on the data set. I picked the suggested question "What is the breakdown of year_1997 by Tourism and Country?" The three terms related to three columns in the data which Watson apparently considered to be important columns.

|Composing a filter|
Next I took a look at the "Metric" column which mixed people count with revenue. Thus, I filtered for values that were either showing the arrivals or departure count for tourists. This can be done by clicking on the column header, selecting "Set condition" and then composing the filter. In my case it was a "begins with" predicate for the arrivals and the same for the departures combined with an OR. "Done" and applied, the data looks much better. Why not create another visual? But first I saved the data. This causes Watson Analytics to list two data sets, the original one and another one labeled "refinement" (which also has a higher data quality score). It is also possible to give the improved data set another name.
After picking the refined data and I typed in a question myself. Watson took it and suggested alternatives to my question. We agreed on "How do the values of year_2008 compare by Country and Tourism?" Watson created a chart which I didn't find too impressive. Hence I clicked on the graph type selection and chose a bar chart. Here is a section out of the result, showing the data for some countries including France and Germany. Guess which color represent inbound and outbound tourism? What is more popular, the Eiffel Tower or the Oktoberfest (or Carnival)...? Anyway, enjoy the weekend and take some time to explore the Analytics Exchange and Watson Analytics.
