Nowadays it is increasing the tendency of using agents on behalf of information systems in their interactions with other autonomous information systems. Moreover, there exists an actual interest on getting these interactions at a semantic level, that is, beyond the syntactic level interaction provided by the XML format standard. In this paper we present a mechanism that gives an step forward in the global goal of achieving a semantic interoperability among agents. The mechanism is based on ontological commitments on the classes of messages interchanged by agents of different information systems in an scenario where agents act in a sincere, helpful and liberal way. Furthermore those messages are considered as individuals of OWL classes, and we take advantage of the reasoning supporting OWL ontologies. 1

The purpose of developing Aingeru has been to overcome the main constraints that tele assistance services nowadays present: they are passive (they react only when the user requires it); their coverage is limited; and, they do not monitor automatically vital signs. By contrast, Aingeru, by using PDAs (Personal Digital Assistants), wireless communications and semantic web and agent technologies, provides a service with the following features: it is active (it reacts automatically in the face of anomalous situations); it can work anywhere and anytime; and, it can monitor vital signs and generate an alarm when necessary. Furthermore Aingeru permits physicians and relatives concerned with Aingeru users to consult data about them through the web. The main focus of the paper is on presenting the architecture of Aingeru and three aspects that are used in its development: ag...

A New Mechanism for the Interoperability of Data Systems

However, what it is still missing is the possibility of a real and efficient interoperation among those systems. In this paper we present a new mechanism that favors the interoperability of agent based data systems. That mechanism permits an agent of a system 1) to send suitable messages to agents of another system without requiring the establishment of a common communication pattern in advance; and 2) to understand, completely or partially, the messages that are sent by agents of other systems. Moreover, the mechanism also allows the communication among agents that follow different standard languages such as FIPA-ACL and KQML. The main support of the proposed mechanism is an ontology that is divided into three interrelated layers and four different categories. This work is supported by a grant of the Basque Government.

We rate the assistance as high quality because allows the monitoring of vital signs and a local detection of anomalous situations by the device that the person carries in real time. Therefore, it sends alarms autonomously when necessary. Through this paper we explain the three main functionalities offered by AINGERU: universal assistance anywhere and at any time, monitoring of vital signs irrespective of location or time and remote monitoring by allowing authorized external persons to consult data about monitored persons using the Internet. Moreover we show how those functionalities are achieved by making use of PDAs (Personal Digital Assistant), wireless communication, Semantic Web, Web services and agent technologies.

Semantic Interoperation Among Data Systems at a Communication Level

However, many problems must be solved yet before a real interoperation becomes true. In order to overcome the existing problems, there is a considerable number of proposals that can be found in the specialized literature that promote the idea of semantic interoperability. A new framework to achieve semantic interoperability among agent based data systems at a communication level is proposed in this paper. This framework permits agents belonging to different data systems 1) to send each other suitable messages without requiring the establishment of a common communication pattern in advance; 2) to understand, completely or partially, those messages that are interchanged among themselves; and 3) to invoke web services offered by the data systems at a high level without needing to go into technical details. An ontology that captures the semantics of different communication acts is the key element for supporting the functionalities provided by the framework. Furthermore, the framework has been extended to support semantic descriptions of web services, which favor their automatic discovery. The usefulness of the presented framework is evaluated using two case study of interoperation among heterogeneous data systems; on one side through the agents of those systems, and on the other side, through the combination of an agent and a web service.

On the one hand, new advances in the area of network communications have facilitated in some way the intercommunication among heterogeneous information systems located at different places. However, what is still missing is the possibility of a real and efficient interoperation among those systems in an open environment as the one favoured by Internet. On the other hand, agent technology provides platforms where cooperative work of information systems is concernable because of the software agents working on behalf of these information systems. But, nowadays that cooperation is in general restricted and requires a laborious a priori preparation. In this paper we present the features of a formal ontology that can play a relevant role in the development of a new kind of information systems interoperation frameworks. The ontology includes classes and properties for describing communication acts among agents. We claim that the communication acts ontology provides interoperability support due to the recognition of communication acts from one Agent Communication Language (ACL) as instances of communication acts in another ACL. Sometimes the comprehension will not be complete, but partial comprehension of the communication may be useful and preferable to the ''not understood'' answer given nowadays. Terms of the ontology are described as classes or properties using the Web Ontology Language OWL.
