GEOCROWD

Jochen Schiller

"Geogrowd - Creating a Geospatial Knowledge World" aims at establishing a fertile research environment by means of a training network that will promote the GeoWeb 2.0 vision and advance the state of the art in collecting, storing, analyzing, processing, reconciling, and making large amounts of semantically rich user-generated geospatial information available on the Web. Specifically, activities will focus on (i) exploiting user-contributed geospatial data, (ii) Web-geodata management and (iii) ...

GROPUS

GROPUS - an Adaptive Rule-Based Approach to Information Extraction   Internet, mass media, scientific literature are the source of huge, continuously growing amount of information that is comprised by natural language texts and stored in digital form. This information can hardly be immediately accessed and processed by computers while human access is often connected with a time-consuming search. Extracting and storing it in a formal representation (e.g. in form of relations in databases) ...

GeoStream

The recent advent of Web 2.0 has placed individuals, their information and their social connections to the center of the Internet stage: the Internet has evolved from being an academic and business tool, to one of the prime means for casual everyday people to network, communicate, publish and exchange all sorts of different data, and to collaborate on projects and activities. GeoWeb 2.0 is the geographic embodiment of the Web 2.0 vision for the next generation of geographic information ...

SAFEST

Jochen Schiller, Matthias Wählisch

This Franco-German project aims at a comprehensive solution to ensure the safety and security of the general public and critical infrastructures. Specifically, SAFEST addresses the problems of crowd control and area surveillance at airports.  The research in SAFEST focuses on Development and analysis of an area surveillance system that is easy to deploy, inexpensive, resilient against malfunctions of individual components, and respects the privacy of citizens The system will operate in ...

SYMORE

SYMORE - A System for Mobile Replication SYMORE is a novel data replication middleware designed for update anywhere scenarios in mobile ad-hoc networks. It primarily aims at providing high availability of shared data stored in an underlying database system. This is achieved by using full replication combined with optimistic concurrency control. SYMORE also supports transactional properties. Lightweight methods for conflict detection, conflict resolution, and transaction commitment are used. ...

Sentimento

(SENTIment Mining and ExtractioN of Web 2.0 Data)   Contact Info: Jürgen Broß Objectives: Study to which extent annotations, meta-data or text structure available in user-generated web content can be exploited to automatically extract large training corpora for machine learning algorithms in the context of web mining applications. Analyze and categorize different types of available annotations and meta-data. Examine which preprocessing and cleansing steps are ...

SpacialDB

We're an early-stage startup with a soon to be live product and an experienced and fun team. Our product, SpacialDB, is a backend (think database) for Web and Mobile apps with a strong emphasis on Geospatial functionality. We provide developers with an easy to use API to quickly import, query and update their data without needing to worry about the backend management, maintenance and scaling. The service makes it really easy for developers to build advanced Geospatial applications directly via ...

TIE

An Incrementally Trainable Statistical Approach to Information Extraction Most of the information stored in digital form is hidden in natural language (NL) texts. While information retrieval (IR) helps to locate documents which might contain the facts needed, there is no way to answer queries. The purpose of information extraction (IE) is to find desired pieces of information in NL texts and store them in a form that is suitable for automatic querying and processing. The goal of this thesis ...

mapsforge

Agnès Voisard

Overview: The mapsforge project was initiated in 2008 as a student project and currently involves about 10 students and scientific staff. It is centered on the free geo data collected and made available by the OpenStreetMap project. The overall goal of our project is to provide a free and open toolbox that enables the community to easily create new OpenStreetMap-based applications. Provided tools and APIs include solutions for map rendering, route planning and navigation, POI indexing and ...
