Semantic Enrichment

European Data Forum 2014Athens, Greece

March 19th – 20th, 2014

• Link research papers and the facts therein to LOD

• Extract information from PDFs• Tables, figures, structure,

references, named entities

• Integration of LOD concepts into papers

• Objective: crowed-sourced triplification for statistical data

• Semi-automatic creation, storing and merging statistical data• using the RDF Data Cube Vocabulary

7Discovery and visual analysis in LOD

• Query Wizard and Vis Wizard: designed for IT-laymen

9Semantic MindMapsMindMeister

• Thesaurus editing and sharing

• Presentation• Extracted PDF structure

• Insights gained from LOD

• Publishing MindMaps as RDF

European Data Forum 2014Athens, Greece

March 19th – 20th, 2014

• Provide annotated PDFs for the Community

1142-DataSocialising Research Data

• Observation 1: Open Data Platforms today• Domain specific provider (e.g. EU digital scoreboard, Eurostats)

• Data centred (e.g. data set list/management, Datahub/CKAN)

Great data (but unsocial)

• Observation 2: success of the Social Web• Successful web platforms are social: blog, discuss, share,

bookmark

• People engage with the digital item making it more valuable

Socialising resources as success factor

1242-DataSocialising Research Data

• Observation 3: Open Data are not easy to consume• No mass market (such as for images or videos)

• Socialising around data has to focus on a special group of users and needs (interpretation)

Specialised services for socialising data are necessary

• Observation 4: Research Data Properties• Raw data is less of importance for sharing knowledge

• Needs interpretation from different points of view (socialisation)

• Currently sharing but no socialising in LOD

Socialising research data for interpretation and generating insights

1342-DataData Flea Market

• Survey results: low monetary value, high intrinsic motivation• Donation based

• High number of transactions • between small groups of interested people

• on small, aggregated, analysed data sets

Data flea market

• This leads us to the 42-data platform• data-centric discussion forum and marketplace

European Data Forum 2014Athens, Greece

March 19th – 20th, 2014

1442-DataKey Principles

• Data-centric discussions • Re-use many existing data sets

• Combine data, visualisations

• Data discovery• Discovery of data and relationships in the LOD: Query Wizard

• Upload/manage own (aggregated) datasets

• Bookmark your data and interesting findings

March 19th – 20th, 2014

1542-DataEconomic Sustainability

• Customer-to-customer situation

• Long tail of niche topics and transactions• Transactions are low value on average

• Need a high number of transactions to be sustainable

• Valuable micro-transactions • Answers, questions, data sources, data sets, derived insights

• Donations (no legal/contract issues)

• Non-monetary incentives: social reputation models
