Ontology designing is not a trivial task. It was found that the reason Blanco was not able to unify and make an integrated security ontology was due to the fact that he was using the existing ontologies ... The problem with them is that all of these were pretty detailed and ... starting at the bottom and consolidating ideas into fewer core concepts as one moves up is not easy as spotting the commonality between related concepts with very fine details behind them is neither intuitive nor easy (Ch-3) ... So we ought to go a different route ...
We have to develop our own IS ontology from the scratch ... Thus, a renewed focus on tools of the trade ... 5-7 tools seem to be available (Ch-3) but they are linked to certain methodologies and if we decide to use any of these then we would have to somehow conform to that methodology ...
The sequence of steps of going about developing the ontology have to be written down in sufficient details with a measurability - i.e. when could it be concluded that the step in complete ... On the same pattern as Milton's 47 steps (Ch-3, Methodology 13) ...
Knowledge sources to include research papers, IS tools (SW & HW) brochures, IS training manuals and teaching materials ... IS blogs that discuss various security issues - this last source is very interesting as these not considered as authentic/reliable sources by many but from Information Systems perspective and societal wisdom is one of the key source and must be put to use ...
So the tasks for this week are to ...
1. Re-read Chapter 3 in detail for a more fruitful discussion
2. Continue search for more ontologies ...
3. Continue search for knowledge extraction and ontology development tools
4. Down load them and try them out
5. 1st Cut Proposal ... This I guess is the most important one to get going at ...
Since getting the 'love letter' it has been decided that the work must be accelerated to max throttle ... Thus, a formal 1st cut dissertation proposal development is underway ... To ready by Monday, Insha'Allah ...
ReplyDeleteFurther, at least 1 new tool, downloaded, installed and be made available for use, Insha'Allah ...
Well, it seems that event Text2Onto is not that easy to install ... BTW this paper "Issues in learning an ontology from text" provides a stepwise plan for creating an ontology and discuss some issues:

Also, another interesting find was Wong 2009,
Doctoral dissertation on "Learning Lightweight Ontologies from Text across Different Domains Using the Web as Background Knowledge"

- The literature review of the ontology engineering tools as well as ontology evaluation methods seem very useful.
It seems that the SIMOnt and related work may be easily incorporated as thesis chapters (describing the complete framework) in addition to FocalPoint (giving an actual IS Ontology as well as the principles of ontology development)
Another interesting observation is that either my literature review needs much more effort or that there are no 'universally' established ontology experts/scientists ... There seems to be many names. Perhaps it is due to the vast range of activities employed in ontology development with each area having its own experts ... Or ... It may be due to the English vs. Non-English speaking world ... Or ... NA vs EU Vs Orientals ... A sub track/chapter might be (and even if it is seems tangent to my current focus that I must try) to compile a list of all the experts and published scholars in this field according to their specialties, native language/country, etc.
