Semantic web at IMSS

Main question:




How can we go ahead on Semantic Web
and ontologies at IMSS?

Florence, 16 June 2003

Semantic web at IMSS

Try to answer:


Evaluation of the achieved outcome


How we can make an ontology


Mesmuses experience


Beyond Mesmuses


Resources to make the ontology run


Critical points


Hypothesis on achievable results

Semantic web at IMSS

Evaluation of the achieved
outcome


Mesmuses prototypes are very useful
samples of Semantic Web application


Allows data browsing with “intelligent”
search


Opportunity to make searches not only on
words, but on the meaning of words too
(semantic search)


Test semantic search on a history of
science domain

Semantic web at IMSS

How we can make an ontology

Mesmuses experience 1


First try


Theoretical approach


Ontology was designed in
order to model domain of
historic science knowledge


No data were available. Need
for a totally manual data input


Schema and instances were
very subjective


Useful for itineraries, not for
search

Mesmuses experience 2


Second try


Bottom
-
up approach


Ontology was designed just looking to
available databases


Deep analysis of databases structure in
order to map relational structure on
ontology concept/property


Data input from relational databases
with little manual attendance


Schema and instances are quite
“objective”, but at the moment don’t
cover all the history of science domain


Useful for search

Links have not any semantics

Beyond Mesmuses 6


Start to re
-
design database for ontology and semantic
search


Mapping of existing database schemas into classes
and properties


Extended Dublin Core


IMSS specifics


Partial automatic indexing of data according to the
mapping rules


Manual actions required to complete indexing process


Design an ontology valid for the whole history of
science community

Florence, 16 June 2003

13

Semantic web at IMSS

Resources to make


the ontology run


Domain experts to map database to ontology


Software for data harvesting


Operators to manually adjust data


Portal


Schema / data loader


Browsing / searching engine


Graphical user interface


Set up a community
-
web and coordinate it


Produce (and agree on) a shared ontology


Share resources

Florence, 16 June 2003

Semantic web at IMSS

Critical points


Ontology production


Integration between ontology and itineraries


Iterative construction of new ontology to make a better coverage
of domain and data


User interface usability


Test of existing interfaces


Requirements to improve interaction effectiveness


Iterates many times this step


Agreement on a community web ontology for history of
science


Impact of a schema modification on existing data


Have mapping of data to be redone?

Florence, 16 June 2003

Semantic web at IMSS

Hypothesis on achievable results


Strongly improve access to IMSS documents
and database



Provide a framework for history of science e
-
learning



Share navigable data with the community


Create an access point to the history of science
resources on the web


Create a virtual museum of history of science on the
web independently from the physical location of the
objects
