Project Description

Sequential pattern mining algorithms are extremely useful to identify the most salient patterns in sequences of events [1,2]. These events can be transactions on a database or time-series data. When applying these algorithms on interactions of the user interface the patterns can be used to evaluate the user interface in that they indicate the most common (mis)uses of interactive systems.

However, the output of pattern mining algorithms is typically large and noisy, and requires, typically, the use of trial and error strategies to identify those patterns that are semantically meaningful [3]. This is especially challenging if the users of the mining algorithms are not data mining specialists but developers or user researchers. The objective of this PhD project is to support non-specialists conducting evaluations of interactive systems using sequential pattern mining algorithms. The following three research questions must be answered to address this problem:

RQ1. Can we support researchers in selecting the most suitable sequential pattern mining algorithm that addresses their research objectives while taking into account the type of datasets used?

RQ2. To what extent can this process be automatised?

RQ3. Can we isolate problematic interactions (ie usability problems) from regular patterns of use?
