Motivation for Semantic Web
4
Web Limitations
Doubles in sizeevery six months
Average WWW searches examineonly about 25% of potentially
relevant sites and return a lot ofunwanted information
Information on web is not suitablefor software agents
World Wide Web
Semantic Web
The Semantic Web is avision: the idea of havingdata on the Web defined andlinked in a way that it can beused by machines not just fordisplay purposes, but forautomation, integration andreuse of data across variousapplications.

Word-Wide Correlated Activities
Semantic Web
Grid Computing
Web Services
Agentcities
Agentcities is a global, collaborative effort to construct an open network of on-line systems
hosting diverse agent based services.
WWW is more and more used for application to application communication.The programmatic interfaces made available are referred to as Web services.
The goal of the Web Services Activity is to develop a set of technologies in order to bring Web services to their full potential
FIPA
FIPA is a non-profit organisation aimed at producing standards for the interoperation
of heterogeneous software agents.
Semantic Web is an extension of the currentweb in which information is given well-definedmeaning, better enabling computers and people
to work in cooperation
Wide-area distributed computing, or "grid” technologies, provide the foundation to a number of large-scale efforts
utilizing the global Internet to build distributed computing and communications infrastructures.

GENI – Next Generation Internet GENI - Global Environment for Networking Investigations
(proposed 25 August 2005) The U.S. National Science Foundation (NSF) has proposed a
next-generation Internet with built-in security and functionality that connects all kinds of devices, with researchers challenging the government agency to look at the Internet as a "clean slate."
The GENI Initiative envisions the creation of new networking and distributed system architectures that, for example:
Build in security and robustness; Enable the vision of pervasive computing and bridge the gap between
the physical and virtual worlds by including mobile, wireless and sensor networks;
Enable control and management of other critical infrastructures; Include ease of operation and usability; and Enable new classes of societal-level services and applications.

GUN vs. GENIGUN vs. GENI
GUN initiative intends to provide tools and solutions to make heterogeneous industrial resources (files, documents, services, devices, processes, systems, human experts, etc.) web-accessible, proactive and cooperative in a sense that they will be able to analyze their state independently from other systems or to order such analysis from remote experts or Web-services to be aware of own condition and to plan behavior towards effective and predictive maintenance.

Develop Agent(s) with JADE
Try to develop simple agent scenario based on JADE (or JADE+Eclipse) development environment;
Possible scenario: agent which sends e-mails with fixed congratulation text to the persons from the address book who have a birthday;
Any other scenario of your choice will be OK
![Page 31: Introduction to Agent Technology in Mobile Environment Course Introduction Vagan Terziyan Department of Mathematical Information Technology University.](https://reader030.fdocuments.net/reader030/viewer/2022012913/56649d5f5503460f94a3fab6/html5/thumbnails/31.jpg)

32
Task for the Exercise (according to A. Raja) (1) Consider the home of the future where there are software agents in a
mobile environment that are helping to manage the running of a house. There will be:
(1) Personal assistant agents that will know of your preferences of temperature, humidity, light, sound, etc., and who you want to interact with;
(2) There will be agents that can measure appropriate environmental conditions with specific devices;
(3) There will be agents that effect appropriate environmental conditions with specific devices;
(4) There will be agents that control expenses for the use of appropriate devices;
(5) There will be agents that manage the telephone communications; (6) There will be agents that manage security issues such as fire,
earthquake, flood protection, etc.
![Page 33: Introduction to Agent Technology in Mobile Environment Course Introduction Vagan Terziyan Department of Mathematical Information Technology University.](https://reader030.fdocuments.net/reader030/viewer/2022012913/56649d5f5503460f94a3fab6/html5/thumbnails/33.jpg)
33
Task for the Exercise (according to A. Raja) (2)Assume that the agents are heterogenous (i.e. have not be
generated by one designer), for example when you get a new device it will come with an agent; for instance, the heating measurement agent may not come from the same company as the air-conditioning agent.
Think about the possibility of having these agents work together. What are the capabilities of the agents, what type of cooperation needs to occur among them, are there needs for the agents to negotiate, are there situations where local objectives are at odds with global objectives such as minimizing electrical usage? What type of information needs to be exchanged among the agents?
![Page 34: Introduction to Agent Technology in Mobile Environment Course Introduction Vagan Terziyan Department of Mathematical Information Technology University.](https://reader030.fdocuments.net/reader030/viewer/2022012913/56649d5f5503460f94a3fab6/html5/thumbnails/34.jpg)
34
Task for the Exercise (according to A. Raja) (3)
How would you organize the agents – would you have a hierarchy of agents in terms of their control responsibilities? How would you allow agents to integrate new agents into the system, for instance, when you buy a new device.
What are the specific characteristics required by a language in order that these agents can share information? If there are no dedicated resources for each agent, but rather a pool of resources that can be used by agents, what new issues does this introduce? Do agents need to reason about the intentions of other agents?
![Page 35: Introduction to Agent Technology in Mobile Environment Course Introduction Vagan Terziyan Department of Mathematical Information Technology University.](https://reader030.fdocuments.net/reader030/viewer/2022012913/56649d5f5503460f94a3fab6/html5/thumbnails/35.jpg)
35
Task for the Exercise (according to A. Raja) (4)
In answering these and related issues that you may consider, please be concrete with specific and numerous examples/scenarios. You should first start out the effort by detailing the collection of agents that you see in the house of the future, what their responsibilities are, and their patterns of interaction with other agents.
Outcome of the exercise is report. Including figures, it should be 3-5 pages long.
