A proposal for a set of attributes relevant for Web portal data quality

Abstract

Data Quality is a critical issue in today's interconnected society. Advances in technology are making the use of the Internet an ever-growing phenomenon and we are witnessing the creation of a great variety of applications such as Web Portals. These applications are important data sources and/or means of accessing information which many people use to make decisions or to carry out tasks. Quality is a very important factor in any software product and also in data. As quality is a wide concept, quality models are usually used to assess the quality of a software product. From the software point of view there is a widely accepted standard proposed by ISO/IEC (the ISO/IEC 9126) which proposes a quality model for software products. However, until now a similar proposal for data quality has not existed. Although we have found some proposals of data quality models, some of them working as ''de facto'' standards, none of them focus specifically on web portal data quality and the user's perspective. In this paper, we propose a set of 33 attributes which are relevant for portal data quality. These have been obtained from a revision of literature and a validation process carried out by means of a survey. Although these attributes do not conform to a usable model, we think that it might be considered as a good starting point for constructing one.

Towards the Discovery of Data Quality Attributes for Web Portals

“…As was previously stated, in [2] the best attributes for Web portals were selected, but this selection was made in 2005. Therefore, we wish to make a comparison between the PDQM attributes and the attributes detected in our SLR.…”

“…This SLR is based on a previous SLR [2], which covered the years 1996 to 2005, and in which 33 attributes considered to be relevant for Web portal data quality were chosen. These attributes were then used to define a quality model for the assessment of Web portal data quality, namely PDQM (Portal Data Quality Model), in [3].…”

“…These criteria have been taken from a comprehensive analysis of the corporate websites, and review of the literature in related areas, including the design of webpages [61], the quality of information on the web [62], and quality of the Portal Data [63], as well as other studies including the following [28,[64][65][66].…”

Blog Quality Assessment Tool (BQAT)

“…Scholars now focuses on web information quality [37] because of increased awareness of differences between Web applications and traditional information systems. Caro et al [15] argued that a gap exists among types of information quality specifically developed for web portals. They discovered 33 significant criteria for portal Quality is very essential to the blogging community.…”

“…Nevertheless, these criteria are merely based on individual authors' or bloggers' opinions. 49 blog quality criteria have been consolidated by Zain et al [5,6,7] drawn from related studies focused on website design criteria [8], web information quality criteria for different domains including ecommerce [9], data integration [10], decision making [11], organizational networks [12], personal websites [13,14], web portals [15], criteria extracted from design advice and checklists [16,3,17], and design articles extracted from popular blogs [18,1,2,4,19]. Zain and Ghani [20] provided a relative importance analysis that can help bloggers/blog evaluators/readers focus on the most important criteria during blog category examination.…”
