Abstract: We present an approach and mobile application for the interactive exploration and search of geo-located social media entities from different, distributed data providers on the web. When querying the providers, the returned results typically have some overlap. In addition, one has no guarantee that the providers reply within a given time interval. Thus, in order to provide users with geo-located entities in their vicinity in a timely manner, we need to take the asynchronous nature of the data providers’ replies into account. Our novel on-the-fly entity resolu- tion engine starts the entity resolution once it retrieves the first responses. It incrementally extends the entity resolution model when more responses arrive. Entities are propagated to the client once the resolution engine has processed them for the first time. Resolution results produced at a later point in time are sent as updates to the client and improve earlier, incomplete results. Our experiments show a matching precision of 95% and scala- bility of the on-the-fly entity resolution w.r.t. the number of resources being simultaneously processed.
