Outline

Questions to be answered in next 10 min:

• What problems do we come across while developing ontologies?

• What is MarcOntX and how does it work?• What problems are to be solved in the future?

3

Ontology development (1)

Group of people reaches the agreement on the semantic description of a part from ‘real’ life. The wider the domain is the more fierce the discussion are.

.

4

Ontology development (2)

Second approach of the ontology development is automatic machine learning. We provide multiple data and use learning methods to extract knowledge from them.

5

Problems

• What if we want to incorporate a part of external ontology?

• What should we do when our domain is very data-intensive and it is almost impossible to cover it only by collaborative means?

6

Solution (1)

• A man can do this, but often it is not the most efficient way….

7

Solution (2)

Other solution is to automate this processes, and here the idea of MarcOntX agent was born. It is a tool, that supports easy integration of the ontology with an external one.

Thanks to the fact, that MarcOntX is automatic and fast, we save time and are closer to success!

8

How does it work?

• MarcOnt Portal – collaborative ontology development

9

How does it work (2)

• JeromeDL users can add new items to the library, described with MarcOnt ontology concepts, or with new concepts they find necessary which do not exist in MarcOnt ontology.

10

How does it work (3)

• Ontology learning

11

Problems to solve in the future

• Should every single change be turned into a suggestion? That could flood as with suggestions.

• How to evaluate the quality of suggestion?

12

Epilogue

The idea is ready, now we only need to implement it.
