1 Introduction
Please follow the steps outlined below when submitting your manuscript to the Proceedings of NTCIR
Workshop. This guideline and manuscript are a modified version of the IEEE proceedings ones[3].

2 Instructions
Please read the following carefully.

2.1 Language
All manuscripts must be in English.

2.2 Printing your paper
Print your properly formatted text on high-quality
A4 white printer paper. Those of you who usually use
US Letter paper, bear with us—this layout is for A4
paper, hence the longer-than-usual pages. Adjust thetop-margin if necessary to avoid text running off thebottom of the page. Do not exceed 8 pages for one
task (”task” means either of CLIR, CLQA, PATENT,QAC, or WEB).

2.3 Margins and page numbering
All printed material, including text, illustrations,and charts, must be kept within a print area 16.0 cm(6-3/8 inches) wide by 24.2 cm (9-1/2 inches) high.
Do not write or print anything outside the print area.
Number your pages lightly, in pencil, on the upper
right-hand corners of the BACKS of the pages (for example, 1/8, 2/8, or 1 of 8, 2 of 8, and so forth). Please
do not write on the fronts of the pages, nor on the lower
halves of the backs of the pages.

2.4 Formatting your paper
Body text must be in a two-column format. The total allowable width of the text area is 16.0 cm (6-5/16inches) wide by 24.2 cm (9-1/2 inches) high. Columns
are to be 7.6 cm (3.0 inches) wide, with a 0.8 cm (5/16inch) space between them. The main title (on the firstpage) should begin 3.5 cm (1-3/8 inches) from the topedge of the page. The second and following pages
should begin 2.5 cm (1.0 inch) from the top edge. On
all pages, the bottom margin should be 3.0 cm (1-3/16inch) from the bottom edge of the page.

2.5 Type-style and fonts
Wherever Times is specified, Times Roman may
also be used. If neither is available on your word
processor, please use the font closest in appearance toTimes that you have access to.
MAIN TITLE. Center the title 3.5 cm (1-3/8 inches)from the top edge of the first page. The title should bein Times 14-point, boldface type. Capitalize the first
letter of nouns, pronouns, verbs, adjectives, and adverbs; do not capitalize articles, coordinate conjunctions, or prepositions (unless the title begins with sucha word). Leave two blank lines after the title.
AUTHOR NAME(s), AFFILIATION(s), E-MAIL
ADDRESS(s) are to be centered beneath the title andprinted in Times 12-point, non-boldface type. This information is to be followed by two blank lines.
The ABSTRACT, KEYWORDS and MAIN TEXT
are to be in a two-column format.

MAIN TEXT. Type main text in 10-point Times,single-spaced. Do NOT use double-spacing. All paragraphs should be indented 1 pica (approx. 0.4 cm or1/6 inch). Make sure your text is fully justified—thatis, flush left and flush right. Please do not place any
additional blank lines between paragraphs. Figure andtable captions should be 10-point Helvetica boldface
type as in
Figure 1. Example of caption.
Long captions should be set as in
Figure 2. Example of long caption requiring more than one line. It is not typed
centered but aligned on both sides andindented with an additional margin on
both sides of 1 pica.

Callouts should be 9-point Helvetica, non-boldface
type. Initially capitalize only the first word of section
titles and first-, second-, and third-order headings.
FIRST-ORDER HEADINGS. (For example, 1.
Introduction) should be Times 12-point boldface,initially capitalized, flush left, with one blank line before, and one blank line after.
SECOND-ORDER HEADINGS. (For example,1.1. Database elements) should be Times 11point boldface, initially capitalized, flush left, with one
blank line before, and one after. If you require a thirdorder heading (we discourage it), use 10-point Times,
boldface, initially capitalized, flush left, preceded by
one blank line, followed by a period and your text on
the same line.

2.8 Illustrations, graphs, and photographs
All graphics should be centered. Your artwork must
be in place in the article (preferably printed as partof the text rather than pasted up). If you are using
photographs and are able to have halftones made ata print shop, use a 100- or 110-line screen. If you
must use plain photos, they must be pasted onto yourmanuscript. Use rubber cement to affix the images
in place. Black and white, clear, glossy-finish photos
are preferable to color. Supply the best quality photographs and illustrations possible. Penciled lines andvery fine lines do not reproduce well. Remember, thequality of the book cannot be better than the originalsprovided. Do NOT use tape on your pages!

2.9 Color
The use of color on interior pages (that is, pages
other than the cover) is prohibitively expensive. We
publish interior pages in color only when it is specifically requested and budgeted for by the conference
organizers. DO NOT SUBMIT COLOR IMAGES IN
YOUR PAPERS.

2.10 Symbols
If your word processor or typewriter cannot produce Greek letters, mathematical symbols, or othergraphical elements, please use pressure-sensitive (selfadhesive) rub-on symbols or letters (available in moststationery stores, art stores, or graphics shops).

2.11 Conclusions

Please use footnotes sparingly1 and place them atthe bottom of the column on the page on which they
are referenced. Use Times 8-point type, single-spaced.

Please direct any questions to the production editor
in charge of these proceedings at the NTCIR organization: E-mail, ntc-proceedings@nii.ac.jp.
