Shared Task Description
The goal of this shared task is developing the computer-assisted tools to diagnose several kinds of grammatical errors, i.e., redundant word, missing word, word disorder, and word selection. The input sentence contains one of defined error types. The developed tool should indicate which kind of error type is embedded in the given sentence and its occurred positions. If the input contains no grammatical errors, the tool should return: sid, correct. The output format should be a quadruple of sid, start_off, end_off, error_type , if the input contains a grammatical error. In this output format, sid means the unique sentence identifier, start_off and end_off represent the positions of starting and ending character where a grammatical error occurs, in which each character or punctuation occupies 1 for counting positions, and error_type should be one of defined errors. Examples are shown as follows:
Example 1:
Input: (sid=B2-0880) 他是我的以前的室友
output: B2-0880, 4, 4, Redundant
(Notes: "的" is a redundant character in this input sentence)
Example 2:
Input: (sid=A2-0017) 那電影是機器人的故事
Output: A2-0017, 2, 2, Missing
(Notes: There is a missing word between "那" and "電影")
Example 3:
Input: (sid=A2-0017) 那部電影是機器人的故事
Output: A2-0017, correct
Example 4:
Input: (sid=B1-1193) 吳先生是修理腳踏車的拿手
Output: B1-1193, 11, 12, Selection
(Notes: "拿手" is wrong word. One of correct words should be "好手")
Example 5:
Input: (sid=B2-2292) 所以我不會讓失望她
Output: B2-2292, 7, 9, Disorder
(Notes: "失望她" is a word ordering error. The correct order should be "她失望")
