### Dataset Summary
A major challenge in supervised sentence compression is making use of rich feature representations because of very scarce parallel data. We address this problem and present a method to automatically build a compression corpus with hundreds of thousands of instances on which deletion-based algorithms can be trained. In our corpus, the syntactic trees of the compressions are subtrees of their uncompressed counterparts, and hence supervised systems which require a structural alignment between the input and output can be successfully trained. We also extend an existing unsupervised compression method with a learning module. The new system uses structured prediction to learn from lexical, syntactic and other features. An evaluation with human raters shows that the presented data harvesting method indeed produces a parallel corpus of high quality. Also, the supervised system trained on this corpus gets high scores both from human raters and in an automatic evaluation setting, significantly outperforming a strong baseline.

## Dataset Structure
### Data Instances
Each data instance should contains the information about the original sentence in `instance["graph"]["sentence"]` as well as the compressed sentence in `instance["compression"]["text"]`. As this dataset was created by pruning dependency connections, the author also includes the dependency tree and transformed graph of the original sentence and compressed sentence.
### Data Fields
Each instance should contains these information:
- `graph` (`Dict`): the transformation graph/tree for extracting compression (a modified version of a dependency tree).
- This will have features similar to a dependency tree (listed bellow)
- `compression` (`Dict`)
- `text` (`str`)
- `edge` (`List`)
- `headline` (`str`): the headline of the original news page.
- `compression_ratio` (`float`): the ratio between compressed sentence vs original sentence.
- `doc_id` (`str`): url of the original news page.
- `source_tree` (`Dict`): the original dependency tree (features listed bellow).
- `compression_untransformed` (`Dict`)
- `text` (`str`)
- `edge` (`List`)
Dependency tree features:
- `id` (`str`)
- `sentence` (`str`)
- `node` (`List`): list of nodes, each node represent a word/word phrase in the tree.
- `form` (`string`)
- `type` (`string`): the enity type of a node. Defaults to `""` if it's not an entity.
- `mid` (`string`)
- `word` (`List`): list of words the node contains.
- `id` (`int`)
- `form` (`str`): the word from the sentence.
- `stem` (`str`): the stemmed/lemmatized version of the word.
- `tag` (`str`): dependency tag of the word.
- `gender` (`int`)
- `head_word_index` (`int`)
- `edge`: list of the dependency connections between words.
- `parent_id` (`int`)
- `child_id` (`int`)
- `label` (`str`)
- `entity_mention` list of the entities in the sentence.
- `start` (`int`)
- `end` (`int`)
- `head` (`str`)
- `name` (`str`)
- `type` (`str`)
- `mid` (`str`)
- `is_proper_name_entity` (`bool`)
- `gender` (`int`)
