== Improvements to Data Collection == | |||
* Add visit_type summation to capture usage of bookmarks and overall visitation patterns (link click, bookmark, etc) | |||
** select count(*) as N, visit_type from moz_historyvisits group by visit_type | |||
* Compute distribution metrics on Session Length to inform design of trail style history visutalizations | |||
** sum of square, cubes, and 4th powers provides greater ability to characterize a distribution than min, max, mean, median | |||
== Problems with Places == | |||
The following problems in the database schema, APIs, or Places in general are preventing really interesting experimentation, analysis, or user experience: | |||
* Tab spawns... (fill me out!) | |||
== Related Research == | |||
* Hartmut Obendorf, Harald Weinreich, Eelco Herder, Matthias Mayer. Web Page Revisitation Revisited: Implications of a Long-term Click-stream Study of Browser Usage in: CHI 2007 | |||

** Classifies use of history into 3 tasks: short-term revisits (backtrack or undo), medium-term (re-utilize or observe) and long-term revisits (rediscover) | |||
** 70% of revisits occur within 1 hour | |||
** Bookmarks trigger less than 12% of url visits | |||
