This paper describes the objectives, choices, and first results of the FEMUS project in building a federated multilingual database system. The focus is on semantic issues, concentrating, in particular, on data model translations and database integration in a heterogeneous environment. Also discussed are mechanisms for exchanging data and metadata, and related implementation aspects. __________ ...

Grid computing is becoming a research focus in distributed and parallel systems. The idea of the grid service being a kernel of the whole grid architecture is accepted by the researchers. The grid service has the characteristics of high scalability and dynamic. By analyzing the resource management in heterogeneous environment and agent-based hierarchy model, this paper presents an agent-based d...

This study presents an ontology-based and multi-agent system for PPHIIS assessment, an integrated information system for the health of People’s Police (PPHIIS) was investigated, and an ontology model was designed and implemented to represent the health domain knowledge combined with the agents’ cooperation, the SORCE-ontology model not only solved semantic problems about heterogeneous data but ...

This paper proposes a new methodology to study environments with unobserved agent heterogeneity. We focus on the settings where the heterogeneous factor takes values from an unknown finite set, and the economic model yields testable implications in the form of pairwise inequalities. The method produces a consistent classification of economic agents according to their unobserved types. The paper...

We advocate the event-based communication genre for mobile agent communities, which is useful for exchanging and disseminating large volumes of small lightweight messages. We propose that the publish-subscribe model complements the proprietary or standard agent communication languages. We describe how we implemented the event notification mechanism for mobile agents, and analyse experiments tha...

Data exchange between heterogeneous schemas is a difficult problem that becomes more acute if the source and target schemas are from different data models. The data type of the objects to be exchanged can be useful information that should be exploited to help the data exchange process. So far little has been done to take advantage of this in inter model data exchange. Using a common data model ...

Rezensionen Sinnentstellender Fehler in letztem LDV-Forum: Re-zension zu " Lexikon und Text " (Feldweg/Hinrichs) sowie " Lexikonimport, Lexikonexport " (Hoetker/ Ludewig) In der letzten Ausgabe ist auf schwer nachvollziehbare Weise in der Sammelrezension der beiden Niemeyer-Bände über Lexika (Feldweg/Hinrichs: Lexikon und Text sowie Hoetker/Ludewig: Lexikonimport, Lexikonexport) ein schwerer, s...

“Agents and Artifacts” (A&A) and CARTAGO are becoming increasingly popular as, respectively, a general-purpose programming model and a related infrastructure for developing shared computational environments in agent-based software systems. However, so far there has been no work on developing multiagent systems (MAS) where agents implemented and deployed in different agent-programming platforms ...

Agent-based approach to economic and financial analysis is a suitable research methodolgy for developing and understanding the complex patterns and phenomena that are observed in economic systems. In agent-based financial market models, prices can be endogenously formed by the system itself as the result of interaction of market participants. By using agents for the study, heterogeneous, bounde...

warranty as a kind of service contract today plays a role key in business and legal transactions. in this paper, we present a manufacturer, an agent and a customer's model under different service contracts suggestions. the manufacturer's profit is maximized by determining sale price, warranty period and warranty price. in addition we obtain optimal maintenance cost or repair cost for ...
