Uncertainty in Data Integration and Dataspace Support Platforms
Data integration has been an important area of research for several years. However, such systems suffer from one of the main drawbacks of database systems: the need to invest significant modeling effort upfront. Dataspace Support Platforms (DSSP) envision a system that offers useful services on its data without any setup effort, and improve with time in a pay-as-you-go fashion. We argue that in...
متن کاملA Dataspace Odyssey: The iMeMex Personal Dataspace Management System (Demo)
A Personal Dataspace includes all data pertaining to a user on all his local disks and on remote servers such as network drives, email and web servers. This data is represented by a heterogeneous mix of files, emails, bookmarks, music, pictures, calendar, personal information streams and so on. We demonstrate a new breed of system that is able to handle the entire Personal Dataspace of a user. ...
متن کاملMeasurement uncertainty.
Measurement uncertainty is a statistical parameter which describes the possible fluctuations of the result of a measurement. It is not a mere repeatability but it is at least as high as the intra-laboratory reproducibility. If it is an attribute of a general analytical test procedure it is at least as high as the inter-laboratory reproducibility. Measurement uncertainty can be determined by the...
متن کاملManaging the Desktop Document Dataspace
Documents such as spreadsheets are easy to create, edit, and exchange. However, their use causes a set of well known problems such as poor data quality, lack of multi user support and missing data in backend systems, e.g. for data analysis. In this paper we present our smart file prototype that extends proven concepts from DBMS to the desktop document dataspace. Firstly, we show how documents c...
متن کاملMeasurement uncertainty relations
Measurement uncertainty relations are quantitative bounds on the errors in an approximate joint measurement of two observables. They can be seen as a generalization of the error/disturbance tradeoff first discussed heuristically by Heisenberg. Here we prove such relations for the case of two canonically conjugate observables like position and momentum, and establish a close connection with the ...
