Named-entity Recognition
Named-entity recognition (NER) (also known as (named) entity identification, entity chunking, and entity extraction) is a subtask of information extraction that seeks to locate and classify named entities mentioned in unstructured text into pre-defined categories such as person names (PER), organizations (ORG), locations (LOC), geopolitical entities (GPE), vehicles (VEH), medical codes, time expressions, quantities, monetary values, percentages, etc. Most research on NER/NEE systems has been structured as taking an unannotated block of text, such as transducing: into an annotated block of text that highlights the names of entities: In this example, a person name consisting of one token, a two-token company name and a temporal expression have been detected and classified. Problem Definition In the expression '' named entity'', the word ''named'' restricts the task to those entities for which one or many strings, such as words or phrases, stand (fairly) consistentl ...

Temporal Annotation
Temporal annotation is the study of how to automatically add semantic information regarding time to natural language documents. It plays a role in natural language processing and computational linguistics. About Temporal annotation involves the application of a semantic annotation to a document. Significant temporal annotation standards include TimeML, ISO-TimeML and TIDES. These standards typically include annotations for some or all of temporal expressions (or ''timexes''), events, temporal relations, temporal signals, and temporal relation types. In natural language texts, events may be associated with times; e.g., they may start or end at a given at a time. Events are also associated with other events, like occurring before or after them. We call these relations temporal relations. Temporal relation typing classifies the relation between two arguments, and is an important and difficult sub-task of figuring out all the temporal information in a document.

Precision And Recall
In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space. Precision (also called positive predictive value) is the fraction of relevant instances among the retrieved instances. Written as a formula: \text = \frac Recall (also known as sensitivity) is the fraction of relevant instances that were retrieved. Written as a formula: \text = \frac Both precision and recall are therefore based on relevance. Consider a computer program for recognizing dogs (the relevant element) in a digital photograph. Upon processing a picture which contains ten cats and twelve dogs, the program identifies eight dogs. Of the eight elements identified as dogs, only five actually are dogs ( true positives), while the other three are cats ( false positives). Seven dogs were missed ( false negatives), and seven cats were correctly ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White House
The White House is the official residence and workplace of the president of the United States. Located at 1600 Pennsylvania Avenue Northwest (Washington, D.C.), NW in Washington, D.C., it has served as the residence of every U.S. president since John Adams in 1800 when the national capital was moved from Philadelphia.

The residence was designed by Irish-born architect James Hoban in the Neoclassical architecture, Neoclassical style. Hoban modeled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Constructed between 1792 and 1800, its exterior walls are Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he and architect Benjamin Henry Latrobe added low colonnades on each wing to conceal what then were stables and storage. In 1814, during the War of 1812, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metonymy
Metonymy () is a figure of speech in which a concept is referred to by the name of something associated with that thing or concept. For example, the word " suit" may refer to a person from groups commonly wearing business attire, such as salespeople or attorneys. Etymology The words ''metonymy'' and ''metonym'' come ; , a suffix that names figures of speech, . Background Metonymy and related figures of speech are common in everyday speech and writing. Synecdoche and metalepsis are considered specific types of metonymy. Polysemy, the capacity for a word or phrase to have multiple meanings, sometimes results from relations of metonymy. Both metonymy and metaphor involve the substitution of one term for another. In metaphor, this substitution is based on some specific analogy between two things, whereas in metonymy the substitution is based on some understood association or contiguity. American literary theorist Kenneth Burke considers metonymy as one of four "master tro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Referent
A referent ( ) is a person or thing to which a name – a linguistic expression or other symbol – refers. For example, in the sentence ''Mary saw me'', the referent of the word ''Mary'' is the particular person called Mary who is being spoken of, while the referent of the word ''me'' is the person uttering the sentence. Two expressions which have the same referent are said to be co-referential. In the sentence ''John had his dog with him'', for instance, the noun ''John'' and the pronoun ''him'' are co-referential, since they both refer to the same person (John). Etymology and meanings The word ''referent'' may be diachronically considered to derive from the Latin ''referentem'', the present participle (in accusative form) of the verb ''referre'' ("carry back", see also etymology of ''refer(ence)''); or synchronically analyzable as the addition of the suffix ''-ent'' to the verb ''refer'' on the model of other English words having that suffix. It is defined in the Merriam-W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freebase (database)
Freebase was a large collaborative knowledge base consisting of data composed mainly by its community members. It was an online collection of structured data harvested from many sources, including individual, user-submitted wiki contributions. Freebase aimed to create a global resource that allowed people (and machines) to access common information more effectively. It was developed by the American software company Metaweb and run publicly beginning in March 2007. Metaweb was acquired by Google in a private sale announced on 16 July 2010. Google's Knowledge Graph is powered in part by Freebase. During its existence, Freebase data was available for commercial and non-commercial use under a Creative Commons Attribution License, and an open API, RDF endpoint, and a database dump is provided for programmers. On 16 December 2014, Google announced that it would shut down Freebase over the succeeding six months and help with the move of the data from Freebase to Wikidata. On 16 De ...
