To meet the data-processing requirements for protocol-based decision support, a clinical data-management system must be capable of creating high-level summaries of time-oriented patient data, and of retrieving those summaries in a temporally meaningful fashion. We previously described a temporal-abstraction module (RESUME) and a temporal-querying module (Chronus) that can be used together to pe...

Agent-Based Models are useful to describe and understand social, economic and spatial systems' dynamics. But, beside the facilities which this methodology offers, evaluation and comparison of simulation models are sometimes problematic. A rigorous conceptual frame needs to be developed. This is in order to ensure the coherence in the chain linking at the one extreme the scientist's hypotheses a...

Today, a wide variety of probabilistic and expert AI systems are used to analyze real world inputs such as unstructured text, sounds, images, and statistical data. However, all these systems exist on different platforms, with different implementations, and with distinctly different, often and very specific goals in mind. This paper introduces a concept for a mediator framework for such systems ...

Organizations have to integrate multiple, distributed data sources and repositories for making their business decisions. These data sources include (but are not limited to) databases, object stores, knowledge bases, files systems, digital libraries and legacy systems. Data and/or system integration has become increasing important for enterprise computing. An agent-based mediate-wrapper software...

In this work we present an architecture for XML-based mediator systems and a framework for helping systems developers in the construction of mediator-services for the integration of heterogeneous data sources. A unique feature of our architecture is its capability to manage (proprietary) user’s software tools and algorithms, modelled as Extended Value Added Services (EVASs), and integrated in t...

objective: the present study aimed to review the relationships between procrastination and two self-factors self-efficacy and self-esteem. methods: participants were 140 undergraduates psychology students enrolled in mohagheg ardabili university, ardabil, iran. instruments used for collecting the required data were the student-version of the general procrastination scale (gp-s), general self-ef...

The intermediator framework is required to support heterogeneous subject mediators interoperability in diverse world of mediation platforms that can be observed in distributed digital libraries and other areas. The intermediator framework based on the “local as view” mediation approach is introduced. The paper focuses on a protocol supporting registration of a mediator information (source) at a...

The power of web services can only be realized when web services are utilized as building blocks to dynamically compose new web services. The Building Finder application is an example application that integrates information from several web services by modeling the web services as information sources in a mediator-based architecture. The paper also describes a mediator framework to dynamically ...
