What is CULTURA
• Digital humanities portal supporting the exploration of cultural heritage collections by a range of different users
• Professional researchers and historians
• Students with little or no experience of a particular archive
• There are three digitised collections in the portal
• 1641 Depositions (http://cultura-project.eu/1641/)
• Bureau of Military History - 1916 Rising (http://cultura-project.eu/1916)
• IPSA Collection (http://cultura-project.eu/ipsa)

Motivation and Goals
Increase the engagement of researchers with digital heritage collectionsby inferring social network between researchers and discovering relationshipsamong them; that, by exploiting researchers’ annotations.
• Social network of researchers, based on inferred relations
• Content and people recommendations
• Adaptive personalized search

The 1641 Depositions
• Collection of noisy text documents, mainly of legal nature
• Contain witness testimonies from Irish people following the outbreak of rebellion by the Catholic Irish in 1641
• Contains over 8,000 depositions of 20,000 pages dating from the 17th Century
• Inconsistent in spelling, punctuation and nomenclature

Flexible Annotation Semantic Tool (FAST)
• Annotation is a multimedia object constituted by different signs
• textual signs, image signs etc.
• User can annotate text or image, and create different types of annotations
• Targeted annotation – associated with a specific part of a document
• Note – associated with the entire document
• Annotation has a scope that defines its visibility
• Public, shared or private

Social Networks and Discovery (SaND)
• IBM Social Analytics engine in IBM Connections
• Provides social network and recommendations
• People and content recommendations
• Recommendations for new users
• All involve highly transparent explanations
• Personalized search
• Based on social networks and topicsof interest
• Social relationship analysis
• Social path from person to person
• Social graph visualization
• Community features

SaND meets FAST
Researchers’ annotations are used to infer relationships, suggest groupsof interest, assign “personal profile” to a researcher, and provide
recommendations of people and content.

Summary and Future Work
• Framework for exploiting users’ annotations on texts, thus fostering collaboration and relationships among researchers of heritage collections
• Extending Entity-Relationship model to support social activities
• IBM’s Social Networks and Discovery (SaND)
• Future work includes implementation of the proposed ideas into a prototype and evaluation with actual users
