ABSTRACT
Geo-temporal information is pervasive over textual documents, since most of them contain references to particular locations, calendar dates, clock times or duration periods. An important text analytics problem is therefore related to resolving the place names and the temporal expressions referenced in the texts, i.e. linking the character strings in the documents that correspond to either locations or temporal instances, to the specific geospatial coordinates or the time intervals that they refer to. However, geo-temporal reference resolution presents several non-trivial problems to the area of text mining, due to the inherent ambiguity and contextual assumptions of natural language discourse.

Integrating geographical and temporal influences into location recommendation: a method based on check-ins
In the online-to-offline (O2O) business model, location recommendation plays an important role and is an essential component of the location-based services. The check-in data, which contains both the geographical and temporal information, has been ...
Graph-based Point-of-interest Recommendation with Geographical and Temporal Influences
CIKM '14: Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge ManagementThe availability of user check-in data in large volume from the rapid growing location-based social networks (LBSNs) enables a number of important location-aware services. Point-of-interest (POI) recommendation is one of such services, which is to ...
Detecting geographical references in the form of place names and associated spatial natural language
Recognizing spatial language in text documents, termed geoparsing, is useful for many applications, because together with mapping such language to lat/long values, also known as geocoding, it enables the connection of the unstructured textual realm with ...
