Tailoring Data Quality Models Using Social Network Preferencesly, data quality assessment consists of calculating a synthesizing value by means of a weighted average of values and weights associated with each data quality dimension of the data quality model. We shall study not only the overall perception of the level of importance for the set of users carrying

The Effect of Data Quality Tag Values and Usable Data Quality Tags on Decision-Makinges in certain circumstances. However, there is conflicting evidence as to how or when decision outcomes are affected. In order to improve experimental soundness, the current research addresses possible sources of ambiguity in previous DQ tagging experiments with respect to DQ tag design. In particul

Predicting Timing Failures in Web Services environments, an operation that does not execute on due time may be completely useless, which may result in service abandonment, and reputation or monetary losses. However, existing web services environments do not provide mechanisms to detect or predict timing violations. This paper proposes a web

A Two-Tire Index Structure for Approximate String Matching with Block Movesce between two strings. Our goal is to filter non-candidate strings as much as possible. Based on the two matured filter strategies, frequency distance and positional .-gram, we propose a two-tire index structure to make the use of the two filters more efficiently. We give a full specification of th
