and crime prevention.
Urban data is heterogeneous, noisy, and
unlabeled, which severely reduces its
usability. The goal of the VaVeL project is
to radically advance our ability to use urban
data in applications that can identify and
address citizen needs and improve urban life.

DATA KNOTS
OBJECTIVES
(data enrichment and event sequence mining)
Diversity, Multi- Modality
Functionality
Urban streams are diverse and heterogeneous
not only in content, but also in format
and degree of granularity, with different scales
in space and time, and from sources
with different levels of trust.
Address the most critical issues of current
( big) data management and stream frameworks
in coping with emerging urban sensor data.
Complementarity
Make European urban data more accessible
and easier to utilize by providing a set
of black box components that provide access
and analyze urban data.
Accessibility
Different data sources, provide a different view
of events or aspects of the urban environment.
Lack of Labels and Noise
Machine learning and data mining algorithms
can be hindered by the lack of ground truth
knowledge which makes understanding
of the data difficult.
VISUAL ANALYTICS
(evolution of traffic jams along a selected route)
Constraints and Cost
Urban streams are oftentimes constrained,
meaning that access to them might be limited.

Value
Exploit knowledge emerging from the project
by disseminating it among European industries
involved in Big Data management and analytics
to assist them in tackling current critical issues.
