Abstract: 【Purpose/significance】This paper aims to investigate and mine the scientific data sharing demands (abbreviated as de?
mands) from the perspective of data users (abbreviated as users),provide foundations for data suppliers,data management platforms and related institutions to mine and meet user's demands to the maximum extent,and provide experiences and references for later research? ers【. Method/process】This paper revealed the association between different demands by collecting first-hand data through question? naires,developing requirement concept lattice through formal concept analysis(FCA) and extracting related association rules【. Result/conclusion】The user's focal demands lie in the data quality,acquisition efficiency and platform security; the gender and subject back? ground can best explain the differences between demands【. Innovation/limitation】This paper mines user's demands with FCA theory and tools to expand the application field,but the sample mainly comes from management,therefore the results may not be adequate enough to show the panaroma of user's demands.
