Distributed - KBTA: A Distributed Framework for efficient

computation of Knowledge-based Temporal abstractions

Knowledge-basedTemporal Abstraction

Developed by Prof. Yuval Shahar, 1997

Knowledge (KBTA Security ontology)

Four inference mechanisms:- Temporal Context Forming- Contemporaneous

Abstraction- Temporal Interpolation- Temporal Pattern Matching

Higher Level Meaningful Temporal Information:

- Contexts- Abstractions- Temporal Patterns

Time-Stamped Raw Data:

- Primitive Parameters- Events

The Goal

Develop framework that manage a Parallel Computation of Knowledge-Based Temporal

Abstractions (KBTA) by distributing the computation to stand-alone computation

units.

Major Components

Computational Unit Coordinator Visualization Exploration Application (KBTA GUI)

KBTA Computational Unit

framework installed on them.
