Knowledge Base

During the review meeting in Brussels pointed out as very relevant and very difficult problem


Wp4 zagreb 21 june 2007

  • What has been done in the period from the last meeting:

  • T4.1

  • - Functional specification of the data transformation from patient data defined by the 'Case report form' into the complete set of attributes prepared for knowledge discovery has been done.

  • Open source DW software package Pentaho has been extensively studied and its application tested for some multi-patient managerial tasks and single patients decision support purposes.

  • Work on D21.


Wp4 zagreb 21 june 2007

  • T4.2

  • Retrospective data from UNICZ have been transformed to the standard Weka (‘arff’) and ‘illm’ form. Data have been cleaned manually by elimination of obvious outliers and sparsely populated attributes.

  • Retrospective ANMCO data set has been transformed to the Weka format.

  • D21 on data preparation has been started.


Wp4 zagreb 21 june 2007

  • T4.3

  • Experiments with contrast set mining and Kernel based Support Vector Machine (?) algorithms have started in parallel on available retrospective data.

  • ANMCO seems as a good simulation of data that will be collected by the platform (except continuous data monitoring).

  • We have some results with UNICZ and ANMCO data, but the results are not very optimistic.


Wp4 zagreb 21 june 2007

  • T4.4

  • HF ontology has been upgraded.

  • Meeting in Milan with UNIMIB and AUXOL -> procedural knowledge related to HF has been prepared in the form of 10 sets of rules.

  • In cooperation with JUMC some of the rule sets have been discussed and improved.

  • Additionally, for some common HF related decision problems medical plans have been developed.

  • ontology + rules + medical plans are on line on

  • http://lis.irb.hr/heartfaid/


Wp4 zagreb 21 june 2007

  • T4.4 continued

  • encountered problems:

  • developed HF ontology is large but not appropriate for reasoning (taxonomy) !

  • Open issue: how to integrate ontology (descriptive knowledge) and rules (procedural knowledge) ?

  • possible solution:

  • development of the procedural ontology + development of the ontology interpreter for DSS interface

we have devoted a lot of work to this idea!


Wp4 zagreb 21 june 2007

  • WP4 presentation plan:

  • Knowledge representation for HF domain (D22) - Alan Jović

  • Demo on procedural ontology and ontology reasoning for DSS support - Marin Prcela

  • Data warehousing on HF platform (D21) - Tom Šmuc

  • Discussion on:

  • a) D21

  • b) D22

  • c) KB – DSS interface
