| 中文简介: |  社交网站的列表是在全球范围内不同，但社交媒体的普及是不容置疑的。在640M Facebook的用户，480M 的QZone用户或200M Twitter用户是用来分享意见，见解和媒体作为社会公民的传感器。这给了一个前所未有的对数据的访问哪个研究机构可以进行社交媒体分析，以支持社会智能的应用，如针对在线内容交付，危机管理，组织变革和促进社会发展的欠发达国家一个巨大的数额。本讲座将针对利用社交媒体构建应用程序的挑战。它将侧重于事件的概念，以构建用户的在线活动。我们将简要地示出网络如何语义技术可用于破坏，其中每个社交网络平台会锁住用户的筒仓。然后，我们将本发明的方法相结合语义推理和可视分析检测，从社交媒体活动的事件，并自动寻找媒体（照片和视频），说明事件。我们会检讨众多作品尽量让microposts感（例如挑战提取命名实体和语义/背景知识增强技术的作用），以检测事件。我们将结束这次谈话与研究问题涵盖多学科领域，如信息检索，数据挖掘，语义网络和网络科学社区。 |
| 课程简介: | The list of social networking sites is different around the world, but there is no doubt about the popularity of social media. Users on 640m + Facebook, 480m + qzone or 200m + twitter are used to share opinions, insights and media as social citizen sensors. This gives an unprecedented access to data which research institutions can conduct social media analysis to support the application of social intelligence, such as for online content delivery, crisis management, organizational change and social development in less developed countries. This lecture will address the challenges of building applications using social media. It will focus on the concept of events to build users' online activities. We'll briefly show how semantic technologies can be used for disruption, where each social network platform locks a user's silo. Then, we combine the method of the invention with semantic reasoning and visual analysis detection to automatically find the media (photos and videos) from the events of social media activities and explain the events. We will review many works to try to make microposts sense (such as the role of challenge extraction named entity and semantic / background knowledge enhancement technology) to detect events. We will conclude this conversation with research questions covering multidisciplinary areas, such as information retrieval, data mining, semantic networks and network science communities. |
