The document summarizes the CODE project which aims to establish a web-based ecosystem for linked open data in research. It describes CODE services for semantic enrichment of research papers and creating RDF data cubes. It also outlines three application scenarios - semantic mindmaps, semantic research papers, and 42-Data, a data-centric discussion forum and marketplace. 42-Data aims to socialize research data by allowing data-centric discussions, data sharing and transactions on small datasets.

Semantic Enrichment
European Data Forum 2014
Athens, 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

and merging statistical data
• using the RDF Data Cube Vocabulary

Socialising 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

12. 1242-Data
Socialising 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

13. 1342-Data
Data 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

Key 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

Economic 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
