this paper analyses and compares the performances of business-to-business e-commerce data quality and service quality among the use of the ‘push’ and ‘pull’ models. rosettanet’s original partner interface processes use the ‘push’ model which suffers from data redundancy when the volume of business-to-business transaction increases. however, when the ‘pull’ model is used, although it reduces dat...

Nowadays, a massive volume of data has been produced by a variety of data sources. The easy access to these data presents new opportunities. In this sense, choosing the most suitable data sources for a specific use has become a challenge. The literature contains many works that perform quality assessment in data sources as a mean of solving this issue. However, only few works take into account ...

Abstract: Information quality assessment is the process of inspecting business information to ensure that it meets the needs of the knowledge workers who depend on it. We suggest in this paper that, prior to implementing a system to assess quality, those responsible for information quality can use a subset of clean data to create a statistical model of a decision that relies on the information....

Complementary cell suppression has been used for disclosure limitation of magnitude data such as economic censuses data for decades. This paper examines data quality and data confidentiality characteristics of cell suppression. We demonstrate that when cell suppression is not performed using a proper mathematical model, it can fail to protect. Moreover, we demonstrate that properly executed sup...

This work considers a problem of integrating heterogeneous semi–structured data sources with the purpose of estimating integration quality (IQ). During the integration of such data sources the IQ estimation plays an important role, because correspondences and dependencies within and across the sources are not completely known, the schema or semantics might be missing, which leads to results wit...

Survival analysis is applied to records for length of productive life of Angus cows, fitting several proportional hazards models. It is shown that a piece-wise Weibull model with a time-dependent stage effect can model the distinct annual culling pattern reasonably well. Analyses fitting a sire model suggest some genetic variability, with heritability estimates on the logarithmic scale ranging ...

Poor quality data is a growing and costly problem that affects many enterprises across all aspects of their business ranging from operational efficiency to revenue protection. In this paper, we present an approach that efficiently and robustly discovers conditional functional dependencies for detecting inconsistencies in data and hence improves data quality. We evaluate our approach empirically...
