### Dataset Summary |
|
|
|
The shared task of CoNLL-2003 concerns language-independent named entity recognition. We will concentrate on |
|
four types of named entities: persons, locations, organizations and names of miscellaneous entities that do |
|
not belong to the previous three groups. |
|
|
|
The CoNLL-2003 shared task data files contain four columns separated by a single space. Each word has been put on |
|
a separate line and there is an empty line after each sentence. The first item on each line is a word, the second |
|
a part-of-speech (POS) tag, the third a syntactic chunk tag and the fourth the named entity tag. The chunk tags |
|
and the named entity tags have the format I-TYPE which means that the word is inside a phrase of type TYPE. Only |
|
if two phrases of the same type immediately follow each other, the first word of the second phrase will have tag |
|
B-TYPE to show that it starts a new phrase. A word with tag O is not part of a phrase. Note the dataset uses IOB2 |
|
tagging scheme, whereas the original dataset uses IOB1. |
|
