Quality assessment for Linked Data: A Survey

Abstract: The development and standardization of semantic web technologies has resulted in an unprecedented volume of data being published on the Web as Linked Data (LD). However, we observe widely varying data quality ranging from extensively curated datasets to crowdsourced and extracted data of relatively low quality. In this article, we present the results of a systematic review of approaches for assessing the quality of LD. We gather existing approaches and analyze them qualitatively. In particular, we unify and fo… Show more

“…For example Ahituv (Ahituv, 1989) suggests: timeliness (dimensions: recency, response time, and frequency), contents (dimensions: accuracy, relevance, level of aggregation and exhaustiveness), format (dimensions: media, color, structure, presentation), and cost. Compare these with Zaveri et al's recent survey of Linked Data quality dimensions: accessibility, contextual, dataset dynamicity, intrinsic, representation and trust (Zaveri 2015).…”

“…relational databases, linked data and semi-structured data like csv, json and xml) while linking quality actions to business value. Despite recent progress and the emergence of both commercial and research tools (Zaveri, 2015), semantic data quality tool researchers must address the fact that the majority of the world's data is not stored in RDF graphs. This limits the applicability and impact of their tools and methods.…”

“…Moreover, from the practical point of view this assumption is often essential [14]. Other metrics of linked data quality include coherence of links to other resources or consistency with regard to implicit information [21]. Recent studies pointed out problems with linked data quality concerning non-standardized and variable representation, inconsistency, and lack of interoperability [18,25].…”
