Abstract
In this study a 2D event-to-sequence floor matrix visualization method
and a tool was developed for visualizing multidimensional sequential patterns.
In practice, about 200 sequences can be efficiently displayed at once, and
sequences can be as long as 20 nodes. Nodes (e.g., instances in time) may
consist of up to 30 events (i.e., transactions). Each event may contain up to
20 attributes, which encode more detailed information about each individual
event with colors. The amount of sequences and events is limited by the
display resolution, while the number of nodes and attributes is limited by the
ability of the human eye in utilising colors in an abstract image. The user
can drill down from the initial overview to more detailed views and explore
data interactively by using sorting, brushing, zooming and selection
functions. Two applications, e-commerce transaction and telecommunication
traffic, were used to experiment with the tool. The preliminary results
indicate that the tool is useful in revealing hidden relationships in
multidimensional sequential data.
