Social question-and-answer (Q&A) involves the location of answers to questions through communication with people. Social Q&A systems, such as mailing lists and Web forums are popular, but their asynchronous nature can lead to high answer latency. Synchronous Q&A systems facilitate real-time dialog, usually via instant messaging, but face challenges with interruption costs and the availability of knowledgeable answerers at question time. We ran a longitudinal study of a synchronous social Q&A…

Effects of expertise differences in synchronous social Q&A
TLDR
The findings of the study suggest that synchronous social Q&A systems should consider the relative expertise of candidate answerers with respect to the asker, and offer interactive dialog support to help establish common ground between askers and answerers.
Supporting synchronous social q&a throughout the question lifecycle
TLDR
Data is used from an instant-messaging-based synchronous social Q&A service deployed to an online community of over two thousand users to study the prediction of whether a question will be answered, the number of candidate answerers that the question is sent to, and whether the asker will be satisfied by the answer received.
Mobile Question and Answer System Based on Social Network
TLDR
The tracedriven simulation results show that Q&A system can achieve a high query precision and recall rate, a short response latency and low overhead, as well as quick response to question askers.
Optimal Question Answering Routing in Dynamic Online Social Networks
TLDR
This work proposes an optimal Q&A system that identifies answerers with required expertises and routes the questions with minimum possible response time in dynamic social networks and consistently outperforms the state-of-the-art systems.
Answerer Engagement In An Enterprise Social Question & Answering System
TLDR
It is found that two design features examined in the experiment can affect answerers’ viewing and answering behaviors, which lead to specific design recommendations, which are also discussed in the paper.

Online Question-Answering (Q&A)
TLDR
This chapter reviews various ways in which people seek information from others by asking questions through online services, referred to here as online Q&A, which are categorized as expert- based, community-based, collaborative, and social.
Knowledge Sharing in the Online Social Network of Yahoo! Answers and Its Implications
TLDR
This paper analyzes the online social network (OSN) in Yahoo! Answers and proposes a friendship-knowledge oriented Q&A framework that synergistically combines current OSN-basedQ&A and web Q& a.

Predictors of answer quality in online Q&A sites
TLDR
It is found that a Q&A site's community of users contributes to its success, and it was typically higher in Google Answers (a fee-based site) than in the free sites the authors studied, and paying more money for an answer led to better outcomes.
mimir: a market-based real-time question and answer service
TLDR
It is found that while markets can reduce wasted resources by reducing the number of less important questions and low quality answers, it may also reduce the socially conducive questions and usages that are vital to sustaining a Q&A community.
Referral Web: combining social networks and collaborative filtering
Part of the success of social networks can be attributed to the “six degrees of separation’’ phenomena that means the distance between any two individuals in terms of direct personal relationships is
The anatomy of a large-scale social search engine
TLDR
How trust is based on intimacy and other considerations inform the architecture, algorithms, and user interface of Aardvark, and how they are reflected in the behavior of AARDvark users are described.
Think different: increasing online community participation using uniqueness and group dissimilarity
TLDR
A field experiment formed discussion communities around an existing movie recommendation web site, manipulating two factors that positively influenced participation and offer a practical success story in applying social science theory to the design of online communities.
Talking to strangers: an evaluation of the factors affecting electronic collaboration
TLDR
This empirical study examines factors influencing the success of a commercial groupware system in creating group archives and supporting asynchronous communication and found that conversations and the creation of group archives were more successful in databases with large numbers of diverse participants.
Social matching: A framework and research agenda
TLDR
The scope of social matching systems is clarified by distinguishing them from other recommender systems and related systems and techniques and shows how existing systems explore different points within the design space.
The effect of communication modality on cooperation in online environments
TLDR
This research adapts the social dilemma research paradigm to quantitatively analyze different modes of communication and finds statistically significant differences between different forms of communication, with the voice condition resulting in the highest levels of cooperation.
Social loafing and social compensation: the effects of expectations of co-worker performance.
TLDR
The present research tested the social compensation hypothesis, which states that people will work harder collectively than individually when they expect their co-workers to perform poorly on a meaningful task.
Social loafing and social compensation: the effects of expectations of co-worker performance.
Previous research has suggested that people tend to engage in social loafing when working collectively. The present research tested the social compensation hypothesis, which states that people will
