eventsVis

A tool for analyzing and visualizing temporal descrete events.

This tools allows the user to inspect events in various forms, to see the interactions of events of various types by looking at them temporally, by looking at consecutive patterns and co-occurring patterns and by inspecting the overall duration or count of events througout time.

It also allows simple manipulations of the data such as grouping of adjacent similar events and deciding on co-occurrence and consecutive events thresholds

This tool uses the shiny framework for visualizing events. In order to run it, you need to have R and preferably Rstudio.

EventsVis currently supports these visualizations:

  • Timeline
  • Distribution of events
  • Consecutive events analysis
  • Co-occurring events analysis
  • SQL querying on dataset

Future plans:

  • Context (time in day, day, holidays, season, weather, location and more)
  • Various sequential rules discovery algorithms
  • Common co-occurring and consecutive patterns discovery

You can see a live example of the tool on ShinyApps (a bit slow but works): [https://omrimendels.shinyapps.io/eventsvis/]

In addition, it allows you to group adjacent similar events together (to ignore the effect of multiple events calls that are actually one event in reality).

Events distributions accross sessions:

Consecutive events analysis

Which events occur after others? Notice the cluster around kitchen activity

Co-occurring events analysis

Which events co-occur together with others? Notice the cluster/clique around kitchen activity and around living room activity
