ACADEMIC ADVISOR DR. YUVAL ELOVICI TECHNICAL ADVISOR ASAF SHABTAI TEAM MAOR GUETTA, ARKADY MISHIEV Distributed - KBTA: A Distributed Framework for efficient computation of Knowledge-based Temporal abstractions

Knowledge-based Temporal 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 Performing a KBTA process on the queries.  Represented by stand-alone machines with KBTA framework installed on them.

Coordinator Receives queries from user Analyzes a query Dispatches Plan the CUs Monitoring and visualizing CUs state Get results from CUs

Functional Requirements Handling Query (Analyzing Query and Generating Plans for CUs)  Receive Query  Analyzing the query  Generating plans for a processed query  Aggregation

Functional Requirements contd. CU Management  Register/Unregister  Dispatch Plan/Get results from CU  Monitor and Visualize CU State

Non-Functional Requirements Speed Modularity Optimal distribution strategy
