I have a very big table with lots of names and how much they are searched by date.
I would like to find trending patterns. When does a name rise and when does it fall. Without knowing the name or the pattern before. The rise could be during the seasons of the year but also during a week.
Like a 'warm hat' is trending in winter and falling in summer. Or searches for a "board game" might rise on Sunday and decrease on Monday.
The table looks simplified like this:
winter gloves, 2014-01-01, 200 warm hat, 2014-01-01, 300 swimming short, 2014-01-01, 1 sunscreen, 2014-01-01, 2 .... winter gloves, 2014-07-01, 1 warm hat, 2014-07-01, 1 swimming short, 2014-07-01, 200 sunscreen, 2014-07-01, 300
Which algorithms should I have a look at?
Thanks for any hint, Joerg
