Forschungszentrum L3S – L3S at Work

L3S Research Center in Hannover / Germany

Hannover on the river Leine, is the capital of the federal state of Lower Saxony (Niedersachsen), Germany and was once by personal union the family seat of the Hanoverian Kings of Great Britain, under their title as the dukes of Brunswick-Lüneburg (later described as the Elector of Hanover). At the end of the Napoleonic Wars, the Electorate was enlarged to become the capital of the Kingdom of Hanover.

With a population of 522,944 the city is a major centre of northern Germany, known for hosting annual commercial trade fairs such as the Hannover Fair and the CeBIT. Every year Hannover hosts the Schützenfest Hannover, the world’s largest marksmen’s festival, and the Oktoberfest Hannover, the second largest Oktoberfest in the world.

In 2000, Hannover hosted the world fair Expo 2000. Hannover is also of national importance because of its universities and medical school, its international airport, and its large zoo. The city is also a major crossing point of railway lines and highways, connecting European main lines in east-west-direction (Berlin - Ruhr area) and north-south-direction (Hamburg - Munich et al.).

L3S Research Center – Interdisciplinary Expansion

In order for the L3S to cover all aspects of Web Science „from a single source“, and thereby play a leading role, both Germany and internationally, in the overall evolution of the Web, increased interdisciplinary cooperation between computer science and IT and other disciplines is urgently needed:

Web Governance
Within this area issues of legal and political governance in the fields such as access, data protection, and privacy, along with economic aspect of the Web are the main topics of focus.

Society & Virtual Communities
Includes by performing sociological, psychological, and linguistic research on new forms of communication and cooperation, group behavior, social relationship, and new form of production and innovation on the Web.

Web-enabled Applications
The main focus in this field are possible uses of the web, particularly in the area of life sciences and physical sciences, but also in sciences.

PicAlert! A System for Privacy-Aware Image Classification and Retrieval

A large portion of images, published in social Web2.0 applications, are of a highly sensitive nature, disclosing many details of the users’ private life. We have developed a web service which can detect private images within a user’s photo stream and provide support in making privacy decisions in the sharing context. In addition, we present a privacy oriented image search application which automatically identifies potentially sensitive images in the result set and separates them from the remaining pictures.
