Real-time task recognition based on knowledge workers' computer activities

Abstract

Motivation-Supporting knowledge workers in their self-management by providing them overviews of performed tasks. Research approach-Computer interaction data of knowledge workers was logged during their work. For each user different classifiers were trained and compared on their performance on recognizing 12 specified tasks. Findings/Design-After only a few hours of training data reasonable classification accuracy can be achieved. There was not one classifier that suited all users best. Take away message-Task recognition based on knowledge workers' computer activities is feasible with little training, although personalization is an important issue.

Capturing context and mental state of knowledge workers

“…Regarding automatic recognition of context and user state first steps enabling automatic task recognition were already taken [2].…”

Supervision of learning methods in user data interpretation

“…Research such as the work by Koldijk et al [1] requires users to provide training examples for the classifiers by labeling examples or time slots with the associated task activity or task content. One method to reduce the required input from users that these classifiers need, is by using existing information on possible categories (i.e.…”

“…Research by Koldijk et al [1] showed that the task activity of the user (e.g. writing an e-mail, reading an article) can be reliably determined from these computer interaction Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.…”

The SWELL Knowledge Work Dataset for Stress and User Modeling Research

“…Computer interactions give rich insight in the user's current working behavior. Research by Koldijk et al [10] shows that it is possible to infer the task someone is working on from computer interaction data. Moreover, one could add analysis of contents worked on.…”
