Coding book:

Instead of having one scheme the Chiba scheme consists of three different coding schemes according to

• the unit  of tagging: discourse marker tagging for word or phrase (A)
• utterance unit tagging for one utterance (sentence) (B),  and
• discourse unit tagging for so called discourse segment (C).

The coding book  will be available by WWW in the near future. But it is written in Japanese. The outline of the work is reported at the First International Conference on Language Resources and Evaluation, Spain, May 1998.

"Standardising Annotation Schemes for Japanese Discourse",  A. Ichikawa, et. al.

Number of annotators:
10 coders (WG members)

Number of annotated dialogues:
 

Evaluations of scheme:
 

Underlying task:
route direction, scheduling, telephone shopping, tourist information

List of phenomena annotated:

• conventional: opening, closing
• initiation:  request, suggest, persuasion, propose, confirm, yes-no question, wh-question, promise, demand, inform, other assertion, other initiation
• response:  positive, negative, answer, hold, other response
• follow-up:  understanding
• response with initiation:  The element of this category can be represented as response/initiation

1. U:  hai, etto, shinkanseN waNji hatsu desu ka.
2. (I)  (What's the departure time of the bullet train?)
3. S:  e, jyuu nana ji haN ni natte orimasu.
4. (R)  (It's 17:30.)
5. U:  hai.
6. (F)  (I see.)

Mark-up language:
The markup language is as follows:

<Dialog>
<Utt Id=0000 Utterance_unit=open_dialogue Speker="S"

Topic=scheduling Depth_of_segment=2 >

 [Well] <then> please start.

Discourse markers are tagged in the transcriptions. Utterance unit and discourse unit are described in SGML manner.

Existence of annotation tool:
A modification of DAT (DRI) is used. It includes prediction of utterance unit tag. (Accuracy of prediction is about 70 % in open test.)

Usability:
Information not available.
