A comparison technique for ill-known time intervals

Currently, many existing information systems contain large amounts of data. Prior research shows that many of these data represent time (domain) intervals and many of those may be subject to uncertainty. Moreover, great attention has been attracted by defining, finding or using qualitative temporal relationships between time (domain) intervals. In this context, the framework of Allen relationships is one of the most notable proposals. As a consequence, many existing proposals consider qualitative temporal relationships between time (domain) intervals subject to uncertainty on one hand and regular time (domain) intervals on the other. One of the most novel approaches in this context is given by the ill-known constraints framework. However, this framework does not yet support comparisons between time (domain) intervals subject to uncertainty. In this paper, a proposal is presented to expand this ill-known constraints framework in order to allow it to support the aforementioned temporal comparison, based on the Allen relationships.
