Assigning a question type to the question is a crucial task; the entire answer extraction process relies on finding the correct question type and hence the correct answer type. Keyword extraction is the first step in identifying the input question type. [14] In some cases, words clearly indicate the question type, e.g.,
Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1]
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
In turn, positions can determine a meaningful location, such as a street address. Geoposition is sometimes referred to as geolocation, and the process of geopositioning may also be described as geo-localization. Specific instances include: animal geotracking, the process of inferring the location of animals over time;

Analysis of linguistic data from the device, using pre-trained models that show that some term is frequently mentioned in a certain location (e.g. "the T" vs "the El" vs. "the subway"). Accuracy is improved by: Data scrubbing to filter out or identify anomalies. Statistical analysis of user submitted data.
Geotagging-enabled information services can also potentially be used to find location-based news, websites, or other resources. [1] Geotagging can tell users the location of the content of a given picture or other media or the point of view , and conversely on some media platforms show media relevant to a given location.
