Temporal Dependency Tree Corpus is a collection of Chinese news reports and fairy tale stories annotated with time expressions, events, and temporal relations. Temporal relations in this corpus are represented as a dependency tree structure for each article. Detailed descriptions about Temporal Dependency Tree structures can be found in our paper.

All 120 fairy tale stories are from Chinese Grimm Fairy Tales. 52 news reports are from Chinese Treebank, and 63 news reports are from Chinese Wikinews. The train/dev/test data split in this repository is the split we used in our paper.

Chinese Treebank and Wikinews data are in news_data/, Grimm data are in grimm_data/.

*.txt files are texts of the articles. Each article is preceded with a line filename:<fileID> (e.g. filename:wikinews_ZH_15), and followed by a blank line. Please note:

• In Wikinews data, there are blank lines inside the article text. The annotations are performed on these articles including the blank lines, so please don't remove the blank lines.
• Chinese Treebank *.txt files are not included here.

*.tdt files are the temporal dependency trees for the articles. Each line in a *.tdt file represents one child-parent pair. Each line has 9 fields, separated by tabs:

filename    cSnt    cStart  cEnd    cLabel  pSnt    pStart  pEnd    trLabel

• filename: the file ID
• cSnt: the sentence ID of the child
• cStart: the start word ID of the child
• cEnd: the end word ID of the child
• cLabel: the time expression or event label of the child
• pSnt: the sentence ID of the parent
• pStart: the start word ID of the parent
• pEnd: the end word ID of the parent
• trLabel: the temporal relation label between this child-parent pair

Please note: We use -1 -1 -1 in the place of pSnt pStart pEnd, when the parent is the ROOT of the dependency tree.
