18. A computer-implemented system for extracting location information from unstructured text by utilizing a language model and a classifier, the system comprising: an input element configured to receive the unstructured text; an identifying element configured to identify, via use of the language model and based upon the received unstructured text, a location referred to by the received unstructured text; a determining element configured to determine, via use of the classifier, whether the location referred to by the received unstructured text is also a physical location from where the received unstructured text was sent; and an output element configured to output the determination of whether the location referred to by the received unstructured text is also the physical location from where the received unstructured text was sent; wherein the language model is based upon a source of data that is distinct from the unstructured text.
