Feature	Description
Term	Word
POS Tags	Indicate part-of-speech tagging of each term. For example: CC: Coordinating conjuntion CD: Cardinal Number DT: Determiner EX: Existential there FW: Foreign word These are just a few POS tags. For more details, please refer to this alphabetical list from UPenn.
Entity Tags	The entity tags cover 8 types of named entities: persons, locations, organizations, geo-political entities, artifacts, events, natural objects, time, as well as a tag for 'no entity'. The entity types furthermore may be tagged with either a 'B-' tag or 'I-' tag. A 'B-' tag indicates the first term of a new entity (or only term of a single-term entity), while subsequent terms in an entity will have an 'I-' tag. For example, 'New York' would be tagged as ['B-GEO', 'I-GEO'] while 'London' would be tagged as 'B-GEO'. The annotation scheme for named entities in the GMB distinguishes the following eight classes: Person (PER) - Person entities are limited to individuals that are human or have human characteristics, such as divine entities. Location (GEO) - Location entities are limited to geographical entities such as geographical areas and landmasses, bodies of water, and geological formations. Organization (ORG) - Organization entities are limited to corporations, agencies, and other groups of people defined by an established organizational structure. Geo-political Entity (GPE) - GPE entities are geographical regions defined by political and/or social groups. A GPE entity subsumes and does not distinguish between a city, a nation, its region, its government, or its people (LOC`ORG). Artifact (ART) - Artifacts are limited to manmade objects, structures and abstract entities, including buildings, facilities, art and scientific theories. Event (EVE) - Events are incidents and occasions that occur during a particular time. Natural Object (NAT) - Natural objects are entities that occur naturally and are not manmade, such as diseases, biological entities and other living things. Time (TIM) - Time entities are limited to references to certain temporal entities that have a name, such as the days of the week and months of a year. For all other temporal expressions the tagging layer timex is used (see below). Other (O) - Other entities include all other words which do not fall in any of the categories above.
