空间和时间作为分布式社会网络中信息检索的主要分类标准
Space and Time as a Primary Classification Criterion for Information Retrieval in Distributed Social Networking
摘要：
我们讨论了如何在一个紧凑的方式，时空相关性的信息项，时空相关性的用户，用户的社会关系和语义相关性的信息项之间的隐含关系可能会被利用的信息检索架构，沿着人类的搜索方式。分散和面向代理的架构反映了新兴的趋势，例如即将到来的移动和分散的社交网络作为社交计算的新范式，其目标是满足更广泛和更微妙的相互关联的信息需求，而不仅仅是当前的IR服务可以满足的即时信息需求。我们简要地讨论了为什么使用时空参考作为主要的信息标准隐含地保存其他关系，因此适合这样的架构。最后，我们简短地指出了一个使用维基百科文章进行的大型评估研究的结果。
英文摘要：
We discuss in a compact way how the implicit relations between spatiotemporal relatedness of information items, spatiotemporal relatedness of users, social relatedness of users and semantic relatedness of information items may be exploited for an information retrieval architecture that operates along the lines of human ways of searching. The decentralized and agent oriented architecture mirrors emerging trends such as upcoming mobile and decentralized social networking as a new paradigm in social computing and is targetted to satisfy broader and more subtly interlinked information demands beyond immediate information needs which can be readily satisfied with current IR services. We briefly discuss why using spatio-temporal references as primary information criterion implicitly conserves other relations and is thus suitable for such an architecture. We finally shortly point to results from a large evaluation study using Wikipedia articles.
