| 2nd International Chinese Word Segmentation Bakeoff - Data Release | |
| Release 1, 2005-11-18 | |
| * Introduction | |
| This directory contains the training, test, and gold-standard data | |
| used in the 2nd International Chinese Word Segmentation Bakeoff. Also | |
| included is the script used to score the results submitted by the | |
| bakeoff participants and the simple segmenter used to generate the | |
| baseline and topline data. | |
| * File List | |
| gold/ Contains the gold standard segmentation of the test data | |
| along with the training data word lists. | |
| scripts/ Contains the scoring script and simple segmenter. | |
| testing/ Contains the unsegmented test data. | |
| training/ Contains the segmented training data. | |
| doc/ Contains the instructions used in the bakeoff. | |
| * Encoding Issues | |
| Files with the extension ".utf8" are encoded in UTF-8 Unicode. | |
| Files with the extension ".txt" are encoded as follows: | |
| as_ Big Five (CP950) | |
| hk_ Big Five/HKSCS | |
| msr_ EUC-CN (CP936) | |
| pku_ EUC-CN (CP936) | |
| EUC-CN is often called "GB" or "GB2312" encoding, though technically | |
| GB2312 is a character set, not a character encoding. | |
| * Scoring | |
| The script 'score' is used to generate compare two segmentations. The | |
| script takes three arguments: | |
| 1. The training set word list | |
| 2. The gold standard segmentation | |
| 3. The segmented test file | |
| You must not mix character encodings when invoking the scoring | |
| script. For example: | |
| % perl scripts/score gold/cityu_training_words.utf8 \ | |
| gold/cityu_test_gold.utf8 test_segmentation.utf8 > score.ut8 | |
| * Licensing | |
