Treatment of imprecision in data repositories with the aid of KNOLAP
Traditional data repositories introduced for the needs of business processing, typically focus on the storage and querying of crisp domains of data. As a result, current commercial data repositories have no facilities for either storing or querying imprecise/ approximate data. No significant …

Resolving semantic conflicts through ontological layering
… and in particular, semantic heterogeneity of data models which are built upon ubiquitous data repositories. We investigate whether we can build ontologies upon heterogeneous data repositories in order to resolve semantic conflicts in them, and achieve their semantic interoperability. We …

Evaluation of the Extensible Markup Language (XML) as a means for establishing interoperability between heterogeneous Department of Defense (DoD) databases
… (XML) tools and technologies toward solving data interoperability issues between legacy data repositories. Past efforts to address these issues have largely failed. XML has the capability to address many of the past problems, but this can only be accomplished when the supporting COTS tools …

Automating data visualization through recommendation
Demand for data visualization has exploded in recent years with the increasing availability and use of data across domains. Traditional visualization techniques require users to manually specify visual encodings of data through code or clicks. While manual specification is necessary to create …

MedRec : patient centered medical records using a distributed permission management system
… retain control over who can access their data. We create a network of trusted data repositories, the access to which are determined by a set of 'smart contracts'. These contracts are stored on a distributed ledger maintained by those who generate data. The distributed nature of the system …

Mineral ecology and network analysis of chromium, platinum, gold and palladium
Data collected on the location of mineral species and related minerals from the field have many great uses from mineral exploration to mineral analysis. Such data is useful for further exploration and discovery of other minerals as well as exploring relationships that were not as obvious even to a …
