Information Science / Web Science |
In July 2013 I've joined the Heinrich-Heine-University of Dusseldorf as an associate professor in the field of Web Science. This Web site gives insights into my research profile and current activities, teaching offers, collaborations and partnerships. I also provide supplementary information for visitors, reviewers, applicants, and students.
My current research topics include Information Retrieval, Web Mining, Semantic Web, multi-modal analysis of social media, and cross-lingual retrieval. A novel direction since 2009 is the inter-disciplinary research in the field of Web Science.
You might be interested to learn more about our special interest group FourCats which is working in this field. Recent activities, news and announcements can be found in our WeST Research Blog and on ResearchGate.
Web Science: novel paradigm of inter-disciplinary research on issues related to the us-age and the technologies of the World Wide Web: development and growth models of the Web, its capacity for furthering global knowledge and communication, values of trustworthiness, privacy and respect for social boundaries, examination of the social impact of the Web on human society
Semantic Web: Standards and technologies of the Semantic Web, knowledge management and knowledge acquisition in modern decentralized environments (Linked Open Data, LOD), meta knowledge management (provenance, change, process knowledge, uncertainty), uncertain reasoning
Information Retrieval: efficient analysis and retrieval methods for thematically focused information systems, multi-modal understanding of Social Web contents, detection of events, trends and opinions in Social Media

Koblenz has a very central position in central Europe and in Germany and can be easily reached by plane (including many low-cost airlines, such as Ryanair, Germanwings, Air Berlin, easyJet), by train (the majority of international long-distance trains in Germany pass through the Rhine valley and Koblenz), and by car (three highways, part of the European highway network).
Airport Frankfurt International (FRA): Major international airport about 115 km from Koblenz. All international airlines. Many direct trains to Koblenz, travel time app. 70 min (25 EUR), car ride from the airport app. 60 min.
Airport Cologne-Bonn (CGN): International airport about 100 km from Koblenz, major hub of low-cost airlines Germanwings and AirBerlin. Excellent connection to Koblenz by direct trains, travel time 60 min (14 EUR) car ride from the airport app. 60 min.
Airport Frankfurt Hahn (HHN): International airport 65 km from Koblenz, major Ryan Air hub in Europe. Direct coach link to Koblenz, travel time 70 min (15 EUR) or by car, travel time 40 min.
Airport Dusseldorf International (DUS): International airport 130 km from Koblenz. Many international airlines. Many direct trains to Koblenz, travel time app. 90-120 min (23 EUR), car ride from the airport app. 75 min.
Deutsche Bahn (German Railways): Koblenz is located at the IC/EC track that connects the major cities from north to south in Germany. Many international long-distance trains (including EuroCityNight) to Cologne, Frankfurt, Hannover, Hamburg pass through Koblenz. Direct trains to the airports Frankfurt, Frankfurt-Hahn, Cologne-Bonn, Dusseldorf are available. A dedicated bus link (Bus #20) connects the main station with university campus (15 min).
Use the journey planner of German railways with destination "Koblenz HBF" (Koblenz main station). It is possible to buy tickets online. From Koblenz main station, you can take a bus or taxi to your hotel/hostel or to the Campus. The taxi rank and the large bus station are located in front of the main entrance.
Major car rental companies have offices in all mentioned airports. In general, all non-residents (including non-EU nationals) are permitted to use the driving license (issued by their local authority) during the first 6 months of stay in Germany. Moreover, EU/EWR driving licences are accepted without any temporal limitation. In some cases, care rental companies may require an authenticated translation of the original driving license, in order to ensure your eliglibility. This is often the case if the driving license is partly written in the national language and/or does not clearly indicate categories of vehicles. For instance, Russian "international" driving licenses are known for this kind of questions. Last but not least: Make sure you drive alive! Drive on the right!
For GPS navigation, please use the following target address: 56070 Koblenz, intersection Oberweiher - Universitätsstrasse (50.362318,7.557238). This will bring you to the main entry of the Campus. Parking lots can be found in front of the main entry on the left (quite small), on the right (larger), the way down to the Moselle river on the left side (large) and also - just few steps away - under the big Moselle bridge (huge). Just follow the corresponding signs for parking. All mentioned parking lots are free of charge. Parking lots in the street Oberweiher above the Campus are for short-stay parking (Disc Parking max 2h). Warning: parking outside designated spaces is not allowed, the traffic wardens inspect our parking areas daily.
Koblenz maps: Interactive Map, Google Maps
Campus maps: Interactive Map, Google Maps
The taxi from the city center or the train station to the Campus (8-9 min) costs app. 10 EUR. We recommend to explicitly ask for 'University Campus Metternich' (Metternich is a district of Koblenz). Many years ago, the Campus was located on the opposite side of the city, and some mature taxi drivers may mix up destinations. Taxi services: Bani (+49-261-12600) or Taxi Koblenz (+49-261-33055).
Taking a bus from the city center or from the train station to the Campus takes 12-15 minutes and costs 2,45 EUR for a single journey. A variety of special fares (e.g. 1-day ticket, group ticket for 5 people) are also available. Buses to/from the campus are: #3 (from city center), #15 (from main station/city center) and #20 (from main station, this is the fastest link). Complete Timetables (Campus bus stops are "Winninger Strasse" or "Oberweiher/Uni"). Please consult Interactive Map, Google Maps for detailed information about available bus stops.
For regional bus connections around Koblenz, you should check the VRM Web site. Many destinations can be reached by regional trains. The cheapest way to explore Rhineland is one-day Rhineland ticket which is valid on almost all buses, coaches, and buses in Rhineland-Palatinate and in Saarland. This ticket is available in Internet, from ticket vending machines in train stations, and on the bus from bus driver.

In many cases, non-EU nationals are required to obtain the entry permission (Schengen Visa) for Germany. Please consult the advices of the German Federal Foreign Office for further information regarding your country and visa requirements.
Due to an unique and favourable geographic location (Rhine valley, surrounded by low mountain ranges of Westerwald, Eifel, and Hunsrueck), Koblenz is known for very good weather conditions all over the year. The average air temperature in August/September is rather moderate with ca. 17-18°C, but the last summer 2010 also had very hot weeks over 30°C. For detailed information, check timeanddate.com
Germany is located in the CET/CEST time zone (UTC+1/+2). This means UTC/GMT +2 hours during the summer DST and UTC/GMT +1 hour in the winter time. For more information, look at timeanddate.com.
The German currency is Euro (EUR). Currency exchange desks can be found at all international airports. Lokal bank offices offer currency exchange as well (for safety reasons, they reluctantly exchange big amounts of cash). ATM machines offer cash withdawal by credit cards and Maestro (in almost the cases this service is not free of charge, you should ask your bank about cash withdrawal fees). To estimate exchange rates, play around with Yahoo! currency converter. A full-featured ATM service can be found in a small "Sparkasse"-house at the main Campus entry.
Larger shops and restaurants accept all major credit cards and Maestro as well. Common supermarkets (Aldi, Lidl, Rewe, Norma, Plus) accept Maestro but NOT credit cards. Small shops and pubs may have no electronic payment facilities on site. Tip is accepted but not mandatory, 10% is the common value. Travel cheques are not really common and not widely accepted. Visitors from non-EC countries can benefit from Tax-Free Shopping in Germany.
Koblenz Touristik provides a very detailed and well structured Web portal for Koblenz visitors. Highly recommended!
German mains power system offers 230 V 50 Hz AC, common outlets (i.e. plugs and sockets) are SchuKo (symmetrical plug with side grounding contacts), sometimes also the simpler Europlug (2-pin plug without grounding contacts). Travel stores at all airports and local electronics stores in Koblenz (e.g. MediaMarkt, Saturn, Expert, ProMarkt) offer a broad range of adaptors at reasonable prices. Devices designed for lower voltage levels (e.g. 110V hairdryers) also require a suitable upstream transformer!
Major telecommunication providers in Germany are German Telekom and Vodafone (900 MHz) as well as O2 and E-Plus (1800 MHz). It is recommended to check in advance the roaming conditions for in/out mobile calls. Possible alternatives are Skype/VoIP and callback services (e.g. Bellshare, flat2flat, Flexsys, Sparruf, to name a few). In parallel, the network of public telephone stations is shrinking - at the moment, there is no public telephone box on the Campus.
Mobile internet via UMTS (WWAN aka 3G) has already reasonably good support in Koblenz, Vodafone D2 seems to have the best coverage. Stable HSDPA is available in the city center, EDGE almost everywhere. It is recommended to check in advance your data roaming conditions, many providers do not support roaming at high HSDPA speeds, and volume prices are also quite different.
The Campus offers dedicated W-Lan access vor visitors, which is available for our visitors on request, free of charge. As an alternative, you also can authenticate your W-Lan access via Eduroam, which is fully supported in our University. The bakery and coffee shop "Hoefer" in front of the Campus offers its own W-Lan access for free (!). Wired internet will be available in lecture halls.
There is no public post office and no letter box on the campus. However, there is a full-service Retail Outlet in the REWE shop nearby.
The supermarkets REWE, Norma, Edeka and Aldi are located next to the Campus. A big shopping mall "Löhr Centre" can be found in the city center, it is co-located with main bus interchange.
A huge (one of the largest in Germany) shopping areal with numerous outlets and stores is located in Mülheim-Kärlich near Koblenz. To get there, take the regional Bus #357 from one of the central bus stops in the city (consult VRM Web site for bus stops, timetables and fares). In this case, don't miss also a nice public swimming pool Tauris nearby (Bus #354).
Koblenz Touristik provides further shopping ideas in and around Koblenz.
ESSIR offers full access for disabled attendees on the entire campus: elevators in all buildings, stairs-free pathways and ramps, dedicated restroom facilities. On request, people with disabilities can access the Campus by car and use dedicated parking lots directly in front of particular buildings. Koblenz operates only low-floor buses with improved disabled access, dedicated places for wheelchairs, and call buttons for boarding assistance. Deutsche Bahn (German Railways) offers systematic and comprehensive support for passengers with disabilities.
In Germany, smoking is not permitted in public rooms (including all Campus facilities, city shops, restaurants and pubs, with quite few exceptions). Smoking is also quite expensive: one cigarette packet costs 4.50 EUR and taxes are expected to grow further in near future. Cigarette vending machines can be found in front of the campus entrance (age verification by Maestro chipcard of by driver license), you may also buy cigarettes in kiosks, petrol stations and some shops around, but NOT on the Campus.

Koblenz is a wonderful old Roman town with modern infrastructure and a young spirit. The University of Koblenz offers a fully equipped modern campus with comprehensive congress facilities, convenient hotels nearby, surrounded by a beautiful, UNESCO world heritage landscape of the Rhine valley, historical attractions like medieval Rhine castles, and a convenient infrastructure for travel from all over the world, including four international airports, excellent railway connections, and several highways.
Koblenz is situated in the picturesque landscape of the Rhine and Moselle (UNESCO world heritage), known for excellent wines, romantic medieval castles, Loreley and Goethe. The town owes its name to the Romans who named the castle "castellum apud confluentes" - this means "castle at the confluence of the rivers".
A variety of cultural offers (sightseeing, museums, boat trips on Rhine and Moselle), outdoor activities (hiking, bike tours) and a certain portion of nightlife with several attractive locations in the historical city centre make Koblenz an ideal location for our summer school. Due to a favourable geographic location (Rhine valley, surrounded by low mountain ranges of Westerwald, Eifel, and Hunsrueck), Koblenz is also known for very good weather conditions all over the year.
The University of Koblenz is located on the newest, fully developed university campus in Germany.

I offer a broad range of themes in the field of Web Science as topics for Master theses. Subproblems in particular themes can also be considered for Bachelor theses and Internship theses.
Mentoring and supervision of my Master and PhD students is organized by the principle of "agile research management". The core idea is to adopt some common software development techniques (known as agile development) for the research domain. A nice recent article "SCORE: Agile Research Group Management" explains it works in practice. The core component of our agile research is the special interest group FourCats.
Take a look into the nice article The Care and Maintenance of Your Advisor to learn more about your duties as a graduate or PhD student in my group.

Are we doing good research? The researcher's success is hard to measure directly, but there are some - quite reliable - indicators: regular contributions to high-quality, competitive conferences and journals, high citation rates in the target community, awards and academic distinctions. A number of reliable online sources can be used to find out "who is who" in computer science:
Some portals also provide suitable rankings for authors, conferences, or publications:
Novel trend: measuring impact through Social Media: Alt-Metrics
Most probably the paper was not good enough. Keep up, major revision, resubmission, got through! But maybe the contribution was just too much ahead of time? In this case, you are in good company! The common peer reviewing system does not easily accept too innovative, controversal ideas (btw, the underlying mechanism is explained - in a more general sense - in our CIKM'04 paper "Goal-oriented Methods And Meta Methods For Document Classification And Their Parameter Tuning", see Publications).
Less formally, there is a nice article on this phenomenon, coined "We are sorry to inform you". Read and relax a bit before the next submission deadline.

This is an inofficial name of our special interest group on Web Science. Why four cats? Well, we could call us just "focus group ABC" - but "fourcats" sounds, uhm, less official.
Not yet firmly convinced? Well, then you may think that this name is inspired by several second-order associations with Web Science in the style of Antoni Gaudi:
First of all, in many European languages "four cats" is a metaphor for "a few people". For example, Els Quatre Gats is the name of a famous pub in Barcelona, which was since 1896 a meeting point of progressive artists for interdisciplinary discussions (e.g. first inofficial exhibition of young Picasso was there). Similarly, we are a small interdisciplinary group: one postdoc, four PhD students, and 2-3 graduates. We meet in a quite informal atmosphere, and discuss issues around Web Science.
The mentioned pub "Els Quatre Gats" is located not far away from the quarter of Yahoo! Research Barcelona, which is our partner in many research activities related to Web Science.
The name "four cats" is a pun for "forecast", which indirectly links to our predictive models for multi-lingual retrieval, detection of small comunities and events in social media, and thematically focused retrieval of multimedia art objects in Social Media. Hmm, isn't "four cats" also an anagram for "focus art"?..
P.S. Well, when we talk about artists and Picasso, why not also about Paris? Indeed, we do. The meeting point of French bohemians was the Parisian cabaret Le Chat Noir (i.e. The Black Cat), seriously. Like Els Quatre Gats, it also exists until now.
