Empirical Validation of WebQMDW Model for Quality-based External Web Data Source Incorporation in a Data Warehouse

“…9 The importance value of the media format (text/HTML/pdf/audio/video etc) of the data from the Web Source fitting within the processing ability of the organization, should be: Q.10 The importance value of the degree to which the data from the Web source is worthy of the cost associated (if it requires access fees), should be: Q. 11 The importance value of the amount or quantity of data provided by the Web Source being significant, should be: Q.12 The importance value of the Web Source providing the data within the time constraint specified by the need of organization, should be: Level 2, Dimension 2: Q. 13 The importance value of the description or metadata of the data from the Web Source being easy to interpret in accordance with the Data Warehouse schema, should be: Q.…”

WSEM QT : a novel approach for quality‐based evaluation of web data sources for a data warehouse

“…With the advent of Internet, World Wide Web (WWW) [6] and electronic commerce over the WWW, various organisations started publishing business data over the Internet, providing a viable, simpler‐to‐load and low‐cost solution for accessing external data [3]. In the last few decades, applications that make use of this synergy of data sources available on the web and DW have experienced a huge growth [7–20]. Therefore, it motivates us to focus on the study and assessment of web data as the external data source (EDS) to the DW.…”
