Text Extraction of Spatial and Temporal Information

Natural language analysis tools are very important for Intelligence tasks, since a considerable amount of information is available in documents of various types. The recent increase on use of open source (OSINT) has made documents even more abundant. Intelligence analysts require tools to help inspect, classify and analyze all this raw data. Situating documents (that is, finding their temporal and spatial coordinates) is vital to put events in the proper geo-strategical context; this in turn is an important part of the complex task of interpreting such events. Such information can help analysts relate events. In our project, we analyze documents at the sentence level. Each sentence is translated to a recursive structure anchored by a triple subject-action-object.
