Named Entity Recognition Task

In named entity recognition, one tries to find the strings within a text that correspond to proper names (excluding TIME and MONEY) and classify the type of entity denoted by these strings. The problem is difficult partly due to the ambiguity in sentence segmentation; one needs to extract which words belong to a named entity, and which not. Another difficulty occurs when some word may be used as a name of either a person, an organization or a location. For example, Deniz may be used as the name of a person, or - within a compound - it can refer to a location Marmara Denizi 'Marmara Sea', or an organization Deniz Taşımacılık 'Deniz Transportation'.

The standard approach for NER is a word-by-word classification, where the classifier is trained to label the words in the text with tags that indicate the presence of particular kinds of named entities. After giving the class labels (named entity tags) to our training data, the next step is to select a group of features to discriminate different named entities for each input word.

[_ORG Türk Hava Yolları] bu [_TIME Pazartesi'den] itibaren [_LOC İstanbul] [_LOC Ankara] hattı için indirimli satışlarını [_MONEY 90 TL'den] başlatacağını açıkladı.

[_ORG Turkish Airlines] announced that from this [_TIME Monday] on it will start its discounted fares of [_MONEY 90TL] for [_LOC İstanbul] [_LOC Ankara] route.

See the Table below for typical generic named entity types.

Tag	Sample Categories
PERSON	people, characters
ORGANIZATION	companies, teams
LOCATION	regions, mountains, seas
TIME	time expressions
MONEY	monetarial expressions
