A Visual Data Profiling Tool for Data Preparation

Abstract

In this paper, we propose a tool that implements visual data profiling capabilities for data preparation – an essential step in the process of linked data generation. Our tool features visual data profiling – a technique that identifies and visualizes potential data quality issues, relevant data cleaning functions, and an interactive spreadsheet table view. The proposed demonstration of the tool will focus on the use of visual data profiling in a scenario of cleaning and transforming tabular weather data – as a pre-processing step for linked data generation.
