In location-based social Q8A services, people ask a question with a high expectation that local residents who have local knowledge will answer the question. However, little is known about the locality of user activities in location-based social Q8A services. This study aims to deepen our understanding of location-based knowledge sharing by investigating the following: general behavioral characteristics of users, the topical and typological patterns related to geographic characteristics, geographic locality of user activities, and motivations of local knowledge sharing. To this end, we analyzed a 12-month period Q8A dataset from Naver KiN “Here,” a location-based social Q8A mobile app, in addition to a supplementary survey dataset obtained from 285 mobile users. Our results reveal several unique characteristics of location-based social Q8A. When compared with conventional social Q8A sites, users ask and answer different topical/typological questions. In addition, those who answer have a strong spatial locality wherein they primarily have local knowledge in a few regions, in areas such as their home and work. We also find unique motivators such as ownership of local knowledge and a sense of local community. The findings reported in the article have significant implications for the design of Q8A systems, especially location-based social Q8A systems.

基于位置的知识共享的局部性

在基于位置的社交 Q8A 服务中，人们提出的问题寄希望于具有当地知识的当地居民来回答问题。然而，对于基于位置的社交 Q8A 服务中用户活动的位置知之甚少。本研究旨在通过调查以下内容来加深我们对基于位置的知识共享的理解：用户的一般行为特征、与地理特征相关的主题和类型模式、用户活动的地理位置以及本地知识共享的动机。为此，我们分析了来自基于位置的社交 Q8A 移动应用程序 Naver KiN “Here”的为期 12 个月的 Q8A 数据集，以及从 285 名移动用户获得的补充调查数据集。我们的结果揭示了基于位置的社交 Q8A 的几个独特特征。与传统的社交 Q8A 网站相比，用户提出和回答不同的主题/类型问题。此外，那些回答的人具有很强的空间局部性，其中他们主要在少数地区拥有当地知识，例如他们的家庭和工作领域。我们还发现了独特的激励因素，例如对当地知识的所有权和当地社区意识。文章中报告的发现对 Q8A 系统的设计具有重要意义，尤其是基于位置的社交 Q8A 系统。我们还发现了独特的激励因素，例如对当地知识的所有权和当地社区意识。文章中报告的发现对 Q8A 系统的设计具有重要意义，尤其是基于位置的社交 Q8A 系统。我们还发现了独特的激励因素，例如对当地知识的所有权和当地社区意识。文章中报告的发现对 Q8A 系统的设计具有重要意义，尤其是基于位置的社交 Q8A 系统。
