Provenance Management for Data Quality Assessment
نویسندگان
چکیده
The ultimate goal of data quality management (DQM) is to improve the data quality (DQ) to facilitate enterprises decision-making, and the data quality assessment (DQA) is an important aspect in the process of DQM. Existing research in DQA focuses on the establishment of evaluation indicators and quantified methods in specific areas of application, but does not take into account the evolution of the data. For the current context of complex heterogeneous data environment, DQA framework based on provenance and SOA is designed, and provenance management process is focused to describe, finally the provenance model is defined and implemented. Overall, an example described in the paper demonstrates the necessity and feasibility of introducing provenance into DQA.

متن کاملA QUAL: A Provenance-Aware Quality Model
In this paper we present a model for quality assessment over linked data. This model has been designed to align with emerging standards for provenance on the Web to enable agents to reason about data provenance when performing quality assessment. The model also enables quality assessment provenance to be represented, thus allowing agents to make decisions about re-use of existing assessments. W...

متن کاملUsing Web Data Provenance for Quality Assessment
The Web of Data cannot be a trustworthy data source unless an approach for evaluating the quality of data on the Web is established and integrated as part of the data publication and access process. In this paper, we propose an approach of using provenance information about the data on the Web to assess their quality and trustworthiness. Our contributions include a model for Web data provenance...
