“…Next, we should also note that, according to previous research on information-seeking behaviors, although an appropriate amount of information is a necessary condition for enhanced performance, the quality of information also matters quite significantly [14]. Especially, in regards to health-related information, the credibility of information is one of the most critical factors of determining one's behaviors of seeking such information [15].…”

This study paid attention to the notable increase of the use of diet/exercise apps on smartphones. Based on channel expansion theory and technology acceptance model (TAM), this study investigated how three predictors-Internet information use efficacy, Internet information credibility, smartphone use efficacy-affected one's attitude toward and intention to use diet/exercise apps. Results from a path analysis indicated that Internet information use efficacy and smartphone use efficacy positively predict the perceived ease of use of diet/exercise apps. Internet information credibility positively predicts the perceived usefulness of such apps. Moreover, there were gender differences in the effects of both Internet information use efficacy and Internet information credibility on the perceived usefulness of diet/exercise apps.

“…Indeed, there is evidence to suggest that consumers are often overwhelmed by the information they receive (Mai 2013), and struggle to assess its value (Ruževičius and Gedminaitė 2007). Barriers to the assimilation of information include cognitive limitations (Zühlsdorf and Spiller 2012) and time pressure at the point of purchase (AlTal 2012).…”

Management AbstractPurpose: Employees eat regularly in workplace foodservice settings, thus the food served can significantly impact their overall diet. Workplace foodservice providers are facing several challenges, including changing consumer demands, partial blame for high levels of obesity and the delivery of accessible information that can encourage healthier food choices. This paper explores the industry perspective on consumer information needs and will assess the challenges faced by foodservice providers in terms of responding to these in a workplace setting. Methodology:A qualitative approach was adopted, involving ten in-depth semi-structured interviews with contract catering managers in the UK and Germany. Social Implications: The provision of enhanced dish information has been found to influence consumers' to make more healthful selections. This is an important public health issue given the growing rates of obesity and diabetes type 2.Originality: This study makes an original contribution by exploring the industry perspective on consumer needs for information and on how this information can be provided.

“…Even though Mai (2013) argues that "information quality is context-dependent, and can only be assessed and understood from within specific situations and circumstances" (p. 675), it seems that, for big data, information context is important only for the choice of the most appropriate tools to reduce uncertainty and establish veracity.…”

This paper argues that big data can possess different characteristics, which affect its quality. Depending on its origin, data processing technologies, and methodologies used for data collection and scientific discoveries, big data can have biases, ambiguities, and inaccuracies which need to be identified and accounted for to reduce inference errors and improve the accuracy of generated insights. Big data veracity is now being recognized as a necessary property for its utilization, complementing the three previously established quality dimensions (volume, variety, and velocity), But there has been little discussion of the concept of veracity thus far. This paper provides a roadmap for theoretical and empirical definitions of veracity along with its practical implications. We explore veracity across three main dimensions: 1) objectivity/subjectivity, 2) truthfulness/deception, 3) credibility/implausibility -and propose to operationalize each of these dimensions with either existing computational tools or potential ones, relevant particularly to textual data analytics. We combine the measures of veracity dimensions into one composite index -the big data veracity index. This newly developed veracity index provides a useful way of assessing systematic variations in big data quality across datasets with textual information. The paper contributes to the big data research by categorizing the range of existing tools to measure the suggested dimensions, and to Library and Information Science (LIS) by proposing to account for heterogeneity of diverse big data, and to identify information quality dimensions important for each big data type.
