Answer queries over Internet-of-Things sensor data, overcoming issues of missing data

What is it about?

With the widespread use of sensor data, there is a need to answer queries despite missing data. In particular, we tackle the problem of event co-occurrences when timestamps may be missing.

Why is it important?

We offer a new way to look at event processing with missing data by providing a probabilistic response to queries.
