4Introduction
5 - Crisis Response and Management
- Characteristics
- Multiple collaborators
- Variety of information sources
- Complex organisations
- Highly dynamic
- Managing the information flow (i.e. presenting
the right information to the right person at the
right time) is crucial for a successful crisis
management.

Crisis management is for all also information
management (Rapport Oosting, 2000)
For the effectiveness of actions in fighting the
crisis it is essential that people involved
timely acquire the information they need to take
their decisions.
7Other Examples
Mont Blanc Tunnel Disaster (1999)
Hercules Disaster (1996)

- Current options for information distribution
- Broadcasting leads to information overload
- Information search up to the user. User is
unaware of which information is available.
9 - Research problem
- The problem of selecting and distributing
information to users as a function of their tasks
and the state of their workflow in a
collaborative dynamic setting. - Being able to
- Determine task-relevant information for users
- Adapt to changing information needs of users
- Anticipate future information needs of users
- Actively push the information to the users
10Goal and Approach
11 - Goal
- Develop an information distribution prototype
system that provides users with task-relevant
information. - Approach
- Trainable information distribution system
- Using an adaptive workflow model for role-task
descriptions - Get work context of actors
- Each role has a set of tasks associated
- Use features from tasks descriptions to fasten
learning of method
12 - Text/Document classification (e.g. Recommending)
- From a collection of documents (or fragments)
that are labelled relevant/irrelevant a system
with machine learning can learn to classify new
text messages accordingly. - Normally a large collection of text messages are
needed to create a good classifier. - We deal with short messages and therefore take
predefined descriptions of tasks into account. - Automatically construct context-specific task
profiles

15Current Status
16 - Basic information distribution prototype system
to be able to test dynamic collaborative
situations with information communication. - Goal of this first test is
- To see if adding task descriptions to message
representations of the learning method leads to a
better information distribution. - Replay crisis scenarios.
17Open Question
- We have a problem with finding detailed
descriptions of information flows (e.g. log
files) of crisis/disaster situations to use for
our scenarios. - If you have any of this data or know how to get
it please let us know!!
