Social information access aims to leverage users' past interactions with information systems to provide better access to information for future users. It does this through methods like social navigation, social recommendation, social search, and social visualization. Key challenges include increasing the reliability of indirect feedback from users and finding appropriate bases for determining user similarity to ensure the "wisdom of crowds" is useful for individual users. Merging different social information access technologies also presents opportunities but challenges of integrating different user interaction data.
Empirical studies of adaptive annotation in the educational context have demonstrated that it can help students to acquire knowledge faster, improve learning outcomes, reduce navigational overhead, and encourage non-sequential navigation. Over the last 8 years we have explored a lesser known effect of adaptive annotation – its ability to significantly increase student engagement in working with non-mandatory educational content. In the presence of adaptive link annotation, students tend to access significantly more learning content; they stay with it longer, return to it more often and explore a wider variety of learning resources. This talk will present an overview of our exploration of the addictive links effect in many course-long studies, which we ran in several domains (C, SQL and Java programming), for several types of learning content (quizzes, problems, interactive examples). The first part of the talk will review our exploration of a more traditional knowledge-based personalization approach and the second part will focus on more recent studies of social navigation and open social student modeling
CityFlocks: Designing Social Navigation for Urban Mobile Information Systemskavasmlikon
CityFlocks is a mobile system enabling visitors and new residents in a city to tap into the knowledge and experiences of local residents, so as to gather information about their new environment. Its design specifically aims to lower existing barriers of access and facilitate social navigation in urban places. This paper presents a design case study of a mobile system prototype that offers an easy way for information seeking new residents or visitors to access tacit knowledge from local people about their new community. In various user tests we evaluate two general user interaction alternatives – direct and indirect social navigation – and analyse under what conditions which interaction method works better for people using a mobile device to socially navigate urban environments. The outcomes are relevant for the user interaction design of future mobile information systems that leverage off of a social navigation approach.
Social navigation, user-to-user mediation and participatory mediation spacesLennart Björneborn
Lennart Björneborn discusses social navigation, user-to-user mediation, and participatory mediation spaces. He defines these concepts and outlines barriers to participation. Björneborn also discusses designing for participation through affordances and scaffolding to support interaction across creating, sharing, finding, and other activities. The concept of "adjacent possibles" and expanding opportunities for participation is also covered.
