Stream Reasoning Workshop 2015

The Stream Reasoning Workshop will take place from November 9 to 10, 2015 and is supported by the VCLA.

Katarina Singer


Processing, querying and reasoning over streaming data is studied in different communities such as KR&R, Semantic Web, Databases, Stream Processing, Complex Event Processing, etc., where researchers have different perspectives and face different challenges.

This workshop aims at advancing Stream Reasoning as research theme by bringing together these different views and goals. In addition to invited talks, the workshop will provide opportunities for all participants to engage in discussions on open problems and future directions.

Participation is by invitation only. Registration is free of charge and includes attendance to all workshop events and lectures, coffee breaks, and lunches.

November 9-10, 2015

The workshop will take place at two different places:

Monday, Nov 9: Seminar room of Hotel Kaiserhof, 1040 Wien.
The Hotel itself is at Frankenberggasse 10, the entrance to the seminar room is at the opposite side of the street, Frankenberggasse 13.

Tuesday, Nov 10: TU Wien, 1040 Wien, Gußhausstraße 27-29
Floor 6, Room: “Kontaktraum

Both locations are in 2-min walking distance:



Close subway stations:

– U1 Taubstummengasse (red line)
– U1/U2/U4 Karlsplatz (red/violet/green line)

Subway Map

A single trip with the subway costs 2.20 Eur and can be purchased at all subway stations. For further information on public transport etc, see
