Welcome to the @lis technology net demonstration portal which hosts the cultural heritage and
tourism demonstrations of the @lis technology net project. The work
presented here has been carried out with the assistance of the European Union. The
contents of the site however are the sole responsibility of the authors and can in no
way be taken to reflect the views of the European Union.
The demonstrations developed here are develop on top of the testbed infrastructure and teaching examples also
developed by the project. More general information is available on the main project page.
Demonstration Objectives
The overal aim of the @lis technology net demonstration are to show how next generation
Internet technologies Agent technology, Web Services and Semantic Web can be combined
to create more flexible, dynamic networked applications. Together these technology can be used as the basis for so called Service Based Architectures for distributed applications. These technologies represent a huge technology step beyond the current "publish and browse" web:
- From Web Pages to Services: content and applications (such as reservations, financial transactions,
information subscription and so forth) are available not only to human users using a web browser
(Web pages) but also to automated programs - each function a company provides is coded as a so called
"service".
- From Manual browsing to automated integration: instead of a human user browsing services one-by-one
services can be combined dynamically to form new compound applications - discovering the necessary
services and integrating them to form a coherent combination - such as, for example, selecting a
set of compatible computing resources across different universities to perform a scientific experiment
or combining flights, hotels and car hire from different companies for a trip.
- From tightly integrated to loosely coupled: current large-scale web sites which integrate content
in a given domain (such as those of major tour operators for travel for example) tightly integrate
information/services during system design time and provide a fixed/static service - making it
difficult to add new providers, change fixed standard travel patterns (packages) and often
excluding small local service providers (since they are excluded in collective barganing. In a
Service Oriented World combinations are made more dynamically - enabling different combinations
of services to be used according to changing need and making the resulting market more
accessible to all players.
The basis for the demonstrations is a sample application in the travel and tourism domain. The main components of the demonstration are: deployed and discoverable travel/tourism services in at least 3 Latin American countries, service discovery mechanisms, automated planners for combining discovered services, personalised information services to navigate planned travel scenarios. These components are all deployed and connected using the projects testbed infrastructure.
Individual Demonstrations
Over its lifetime the project will provide three demonstrations showing different levels of
complexity of applications which could be built. These three levels are:
- Spring 2005 - Dynamic Service Browsing: this demonstration makes it possible to dynamically access services deployed in the network in countries in Latin america and browse through them using a browser interface. The system shows how services can be added anywhere and discovered / accessed remotely in a uniform interface. [Now Live!!]
- Autumn 2005 - Automated Dynamic Travel Planning: this level of the demonstration extends demo I by adding automated Artificial Intelligence planning systems which are dynamically able to discover services in Europe and latin America to formulate possible travel plans. The system makes it possible to combine offers from many indipendent providers in an automated fashion and tailor the result to the users requests and personal profile.
- Winter 2005 - Automated Dynamic Travel Planning over Mobile Devices: the final demo shows how the automated travel planning system can be deployed across fixed line internet and wirelessly connected mobile devices - demonstrating connectivity in "wireless demonstration zones" deployed at each partner site.
Demo I: Dynamic Service Browsing
The first alis technology net demonstration is hoted by technologico monterey / Mexico [browser interface], Universidad de Costa Rica / Costa Rica [hosted agent/web services services for tourism in Costa Rica] and Universidad Tecnologica Metropolitana / Chile [hosted agent/web services services for tourtourism in Chile].
Demo II and III
These demonstrations will be available from Autumn 2005 and Winter 2005 respectively.
