The talk will discuss current challenges, approaches and future directions for coping with data variety. The discussion will be grounded on exemplar use cases from leaders in industry and in large-scale scientific projects such as IBM Watson, CrowdFlower, BBC, Press Association, ProteinDataBank, Data.gov.uk, Chemspider among others. The use cases were collected in interviews with Big Data industry and academic experts in the context of the BIG Project and provide a glimpse of the state of the art techniques which are currently being used to cope with data variety and the future directions and emerging trends for this field.

1.  Data curation is enabling more complete and high
quality data-driven models for knowledge
organisations.
 eScience projects are the key innovators while
Biomedical and Media companies are the early
adopters.
 Pre-competitive economic models can support the
creation of curation infrastructures.
 Curation at scale requires blending of automated
curation platforms with large numbers of data curators.
 Improvement of human-data interaction is needed.
 Standards and models needed to reduce data curation
effort.
 Interviews with domain experts, sector
case studies and literature analysis.
 Focus on ,
