An Interactive Framework for Video Surveillance Event Detection and Modeling
We aim at building a framework for high-level event detection in video streams based on a novel temporal extension of relational algebra. With the help of intuitive and interactive graphical user interfaces, a user can have a look at the different layers of our system to gain insights into the inner workings of the system, as well as create new events on the fly and track their processing through the system.

Efficient approximate temporal aggregation
Aggregation is an important but time-consuming operation in temporal databases. Rather than computing an exact solution, this project aims at developing an algorithm to compute an approximate solution for temporal aggregation, which can be efficiently implemented in relational databases and scales for large amounts of data.

HAMSIK — High-level AutoMatic event detection in a SocIal networK context
We aim at developing a framework for the detection of high-level events in a social network context, allowing us to identify abnormal or malicious behavior such as spamming. Additionally, we can classify users by analyzing their typical behavior while logged into a social network site. The processing of (real-time) events in our framework is done via an event detection language called ISEQL, which we adapt and extend to fit the requirements of a social network setting.

Implementation of temporal operators with UDFs
While the storage of temporal data is supported by most database management systems, the support for querying such data is still very limited. This project aims at implementing temporal query support by means of so-called user-defined functions.

SARRI: a SmArt Rapiro Robot Integrating a framework for automatic high-level surveillance event detection
The aim of this project is to integrate a previously developed framework for high-level surveillance event detection with a smart robot to enhance the monitoring process. More specifically, the robot is able to improve the quality of a video stream, which in our earlier work was recorded from a static camera position, by providing a mobile camera, enabling us to get footage from different angles. Furthermore, a robot platform is able to go beyond just contacting security or the police by taking immediate action when a potentially dangerous event is detected: for instance, picking up an unattended package.

Supporting the processing of time series data in relational databases
Time series (TS) data is an important category of data in many application areas, e.g., sensor applications, IoT. To process such data, ad hoc time series data management systems have been developed. This project aims at developing a solution to process TS data in relational database systems.

Social Sensing for Improving the User Experience in Orienteering
we aim at enhancing a tourist trip planning framework based on orienteering with category constraints by adding social sensing. This allows us to customize a user's experience without putting the burden of preference elicitation on the user. We identify the interests of a user by analyzing their Tweets and then match these interests to descriptions of points of interests. For this analysis we adapt different schemes for social sensing to the needs of our orienteering context and compare them to find the most suitable approach.
