Abstract(in English) | Recently, automatic activity log taking is realized by activity recognition techniques with body area sensor networks, and there are some studies to improve working style by looking back on the logs. In activity recognition, supervised-learning method is generally used. However, collecting of labeled data is an obstacle for the system to be practical due to the load. Therefore, we propose ALATA, a annotation tool based on active learning approach to reduce the labeling effort. The ALATA provide an environment where huge amount of annotation data are easily obtained and the labeled data can be continuously collected by linking confirming task and annotating task seamlessly. We conducted an experiment to evaluate the usefulness of the ALATA. The experiment showed that ALATA can reduce the time of labeling. |
