| ### Dataset Summary | |
| Text chunking consists of dividing a text in syntactically correlated parts of words. For example, the sentence | |
| He reckons the current account deficit will narrow to only # 1.8 billion in September . can be divided as follows: | |
| [NP He ] [VP reckons ] [NP the current account deficit ] [VP will narrow ] [PP to ] [NP only # 1.8 billion ] | |
| [PP in ] [NP September ] . | |
| Text chunking is an intermediate step towards full parsing. It was the shared task for CoNLL-2000. Training and test | |
| data for this task is available. This data consists of the same partitions of the Wall Street Journal corpus (WSJ) | |
| as the widely used data for noun phrase chunking: sections 15-18 as training data (211727 tokens) and section 20 as | |
| test data (47377 tokens). The annotation of the data has been derived from the WSJ corpus by a program written by | |
| Sabine Buchholz from Tilburg University, The Netherlands. | |

| ### Data Fields | |
| The data fields are the same among all splits. | |
| #### conll2000 | |
| - `id`: a `string` feature. | |
| - `tokens`: a `list` of `string` features. | |
| - `pos_tags`: a `list` of classification labels, with possible values including `''` (0), `#` (1), `$` (2), `(` (3), `)` (4). | |
| - `chunk_tags`: a `list` of classification labels, with possible values including `O` (0), `B-ADJP` (1), `I-ADJP` (2), `B-ADVP` (3), `I-ADVP` (4). | |
