Where's Waldo?
Barak Pat, Yaron Kanza · 2017
The myriad geotagged posts in the social media constitute a vibrant information source that can be used to support geosocial search, that is, a search for geographic locations based on user activities in online social networks and microblogging platforms. Unlike a traditional geographic search, the results of a geosocial search are not restricted to predefined entities, and may reflect events, sentiments, and other matters that are expressed in the social media. A search for "jogging", for instance, will indicate popular jogging places. A search for "4-th of July Fireworks" would point out places where people watch the spectacle and tweet about it. Yet, geosocial search is different from ordinary Web search because there is no natural partition of the space into documents. There is a need to find new ways to effectively rank, filter, and present results.
