Twitter是一种独特的微博，与传统的社交媒体不同，它的速度很快。很多Twitter的用户都是用手机或者智能手机在现场向Twitter发送消息，其中也有一些用户发送带有照片和地理标签的推文，可以看作是带有地理标签的照片。地理标记的推特照片对于了解当前世界上正在发生的事情非常有用。在演示中，我们介绍了“World Seer”，这是一个实时地理推特照片映射系统。用户可以在在线地图上看到与给定关键词和区域相关的最新地理推特照片。该系统不仅在地图上显示地理推特照片，还在街景上显示。此外，对于部分地理推特照片，系统采用同时考虑照片视觉特征和地理标签接近度的GeoVisualRank方法，可以显示给定地点和给定时间的代表性照片。
Twitter is a unique microblog which is different from conventional social media in terms of its quickness. Many Twitter's users send messages to Twitter on the spot with mobile phones or smart phones, and some of them send tweets with photos and geotags, which can be regarded as being geotagged photos. Geotagged tweet photos are very useful to understand what happens currently over the world. In the demo, we introduce "World Seer" which is a real-time geo-tweet photo mapping system. Users can see the latest geo-tweet photos related to given keywords and areas on the online maps. The system shows geo-tweet photos not only on the map, but also on the street-view. In addition, for some parts of the geo-tweet photos, the system can show representative photos for the given locations and the given times employing the GeoVisualRank method which takes into account both visual features of photos and proximity of geotags.
