Personal Research Statement:
A task common to many application domains is the analysis of data accumulated
over time, leading to identification of past and present trends and to episodic
decisions made on the basis of the previous and the current state of the world.
An example of such a task in the medical domain is managing patients who are
being treated with clinical guidelines. An inherent requirement of such tasks
is to accumulate and to analyze patient data over time and constantly to revise
an assessment of the patient's state by abstracting higher-level,
context-sensitive concepts from the raw input data. These higher-level concepts
can be used for summarizing large medical databases, for monitoring, for
replanning therapy, for providing explanations to a user of a decision-support
system, and as a basis for a more intelligent dialog between an automated
decision-support system and a human health-care provider.
My work focuses on defining basic knowledge-based, domain-independent temporal-abstraction mechanisms and the formal knowledge needed to instantiate them in any particular medical domain. Formalization of temporal-abstraction knowledge supports the acquisition, representation, maintenance, reuse, and sharing of that knowledge. I have therefore defined a knowlede-based temporal-abstraction framework, implemented it as the RÉSUMÉ system , and tested it in several clinical domains. The framework has been expanded and embedded in a larger architecture, Tzolkin , that combines temporal-reasoning and temporal-maintenance services. Tzolkin is used within the EON component-based architecure for guideline-based care. An extension of Tzolkin is the IDAN temporal mediator at Ben Gurion University's Medical Informatics Research Center .
I am also leading the KNAVE (knowledge-based Navigation of Abstractions for Visualization and Explanation) project, which focuses on an interactive framework for visualization and exploration of time-oriented data (e.g., patient clinical data) and their multiple-levels of abstractions. the KNAVE project has been extended into the KNAVE-II project at Ben Gurion University's Medical Informatics Research Center .
I also am interested in (therapy) plan generation, revision, recognition and critiquing in clinical domains; I am leading the Asgaard project, which investigates these tasks. I am also leading the Electronic Digital Guideline Library (DeGeL) project, which creates a distributed framework for specification, retrieval, and use of clinical guidelines.
Both the DeGeL, the IDAN, and the KNAVE-II projects are part of my Medical Informatics Research Center at the Department of Information Systems Engineering of Ben Gurion University of the Negev, Beer Sheva, Israel.
Finally, I am interested in decision-theoretical aspects of clinical decision
making, and I am heading the PANDA
project, which applies decision analytic methodologies to the domain of genetic
consultation.
