• The TIVal project: context, aims, requirements

• Documents produced by the research groups

• Why should we care? How to exploit them to support fruition

• Ontologies (CIDOC) for the TIVal annotation scheme

• From the ontology to the CMS

• Navigation paths in action

• Conclusions and future works

Outline


• Main goals– Realize an integrated

environment for heterogeneous documents describing distinct but related research activities

– Implement effective mechanisms to support their fruition

•Initial analysis

•Identification of knowledge sources

•Planning of Knowledge Acquisition

Analysis of the domain

•Knowledge elicitation (document analysis and interviews)

•Knowledge modeling

Model definition and

implementation

•Encoding of the Knowledge Model

•Implementation of relevant forms

•Loading of documents, data, etc.

System implementation

• Early phases of domain analysis and knowledge elicitation

• Early architectural choices to face requirements: a CMS (Drupal 7) was adopted to assure– minimal user requirements

(both technical and conceptual)

– rapid development of a solid web portal

– openness to Semantic Web or LOD perspectives

Comparison with the state of the art


• Ontologies and Semantic Web technologies often used to

– define and implement a comprehensive knowledge model for integration and sharing

– enable “intelligent fruition”, by means of semantic queries

• CIDOC CRM

– ISO standard model for concepts and relationships used in Cultural Heritage documentation

– well documented and increasingly adopted

– currently being integrated with other widely diffused standards

– available implementations using KR/Semantic Web languages

Ontologies and CIDOC

A fragment of the CIDOC CRM – vers. 5.04


TIVal Basic Conceptual Model


TIVal Ontology


TIVal Ontology – Zoomed


• The TIVal ontology was mapped to the content objects of the CMS

– Classes mapped to content types• Exception: types mapped

to taxonomies

– Properties mapped to node reference fields• Exception: datatype

properties mapped to simple fields

Navigation Paths in Action


• TIVal portal development almost complete– Documents are being loaded, annotated and described by the

research groups

• The Knowledge Elicitation phase was probably the most demanding– TIVal is a highly interdisciplinary project (different vocabularies, aims,

practices...)

• Document loading and annotation also not so simple– It is an additional activity...– ... specifying values and relationships can be problematic...– ... and developing input forms for semantic annotations is not simple

• The definition of template navigation paths essentially employs simple queries but grants– a dynamic exploitation of newly loaded and annotated documents– the possibility to avoid the need of statically a-priori guided navigation

paths

Discussion


• TIVal portal will soon grant an organized navigation of heterogeneous documents produced by different research groups

• The effectiveness (from the perspective of user experience) of navigation paths in supporting fruition will be then evaluated

• The developed knowledge model is general but this should be proved by applying it in different cultural heritage contexts

• The ontology based approach to knowledge modeling can be suitably employed also when adopting a standard CMS...– ... and this approach could be an effective way to actually

produce semantically annotated data

Conclusions and Future Works
