Purpose -Check-in based advertising is growing dramatically as the popularity of social media increases. The purpose of this paper is to explore which social cues are appropriate for check-in based advertising in social media based on media richness theory and how content effectiveness affects content generation intention based on achievement motivation theory. Design/methodology/approach -A laboratory experiment was performed to evaluate the effects of social cue strategies on content effectiveness of attitude toward the ad and self-efficacy on recall. The influence of effectiveness on content generation intention are also measured in the experiment. Findings -The results of a laboratory experiment indicated that a strategy of using plentiful social cues has high effectiveness as measured by the concept of attitude toward the ad. Content effectiveness measured by attitude toward the ad and self-efficacy on recall can directly affect user intentions to generating check-in based advertisements. Research limitations/implications -Although check-in based advertising is driven by the customers themselves rather than by the company, companies can encourage their customers to follow an appropriate check-in content generation strategy to improve effectiveness. Practical implications -The findings of this study provide useful information for designing the content of social media designed to facilitate the promotion of products and companies in online marketing. Originality/value -In theoretical contribution, this study integrates media richness theory and achievement motivation theory to explore how users intent to generate check-in advertising according to social cues effectiveness.
Purpose -This work empirically evaluates the effectiveness of the novel ontology-based access-control mechanism and the common password-protected access-control mechanism for social blogs. The paper aims to discuss these issues. Design/methodology/approach -The ontology-based access-control scheme is designed to fit two characteristics of blog activities: social relationships and tags. A laboratory experiment is conducted to assess the perceived privacy benefit and perceived ease of use of the two mechanisms. Findings -Analytical results indicate that, with the ontology-based access-control scheme, users perceive more privacy benefit than with the password-protected access-control scheme. The perceived ease of use with the ontology-based and password-protected access-control systems did not differ significantly.Research limitations/implications -Cross-boundary collaborations need an appropriate approach to control communication access. Further study is required to evaluate the ontology-based access-control scheme applied in cross-organizational and cross-departmental collaborations. Practical implications -From a knowledge management perspective, blogs can store personal and organizational knowledge and experiences. The ontology-based access-control scheme encourages knowledge sharing for appropriate persons. Originality/value -The new ontology-based access-control mechanism can help online users keep secrets from selected people to gain more privacy benefits than the existing password-protected access-control mechanism.
