Data
| Size: | About 100K words, 325 data files |
| Source: | 325 articles from Xinhua newswire between 1994 and 1998 |
| Coding: | GB code |
| Format: | Same as the UPenn English Treebank except that we keep some original file information was retained such as "SRCID" and "DATE" in the data file. |
| Annotation: | All the files are annotated at least twice, the first-pass is done by one annotator, and the resulting files are checked by the second annotator (second-pass). |
| SGML: | All data files validate against chtb.dtd using nsmls. |
The files are located in the data subdirectory and are sequentially named as follows: chtb_nnn.fid where nnn is the sequential file number. There is a cross reference in file.tbl which provides some annotator and historical information.
