中文字產生,編輯及排版之自動處理系統

Abstract

此篇文章仍為利用電子計算機以處理中文資料之研究,研究包括三項:中文字之 產生,中文之編輯及中文之排版. 在中文字之產生方面,討論到如何於計算機內建立中文典及如何建立新字. 在中文編輯方面,計算機程式首先將中文字[寫]在螢幕上(Dispay Scopc)然後 使用者可以利用光電筆(Light pen)在螢光幕上做去字(delete),加字(insert) ,取代字(replace)移字(move)等之工作. 在中文排版方面,計算機程弋式可以將以編輯好的數篇文自動安排在一固定大 小的紙內,使用者可以很容易變化排版式以得不同的排版結果.此篇文章談到利 用計算機模擬日常聞報紙的排版. 利用計算機做自勤編輯及排版的工作乃為出版工業全自化的基本要素. A document of Chinese may consist of several paragraphs, each consis ting of title and text. Two major problems arise in processing the Chinese document. The first one is the text-editing operation on the individual paragraph. The second problem is the typesetting operatio n on the paragraphs;it concerns the arrangement of many paragraphs i nto a given space (which is called a page in the following discussio ns) so that space is utilized in an economical sense, and the typese t page is easily readable. It will be seen that a display scope is a suitabnle device for perfo rming the text-editing operations of the proposed system. Many text- editing operations have been designed into this system. These includ e delete, insert, replace, alter, and move operations. To save stora ge needed in the dictionary and increase the number of Chinese Chara cters which can be retrieved, some Chinese characters are represente d by a composition of its subcharacters. The dictionary, which consi sts of components (subcharacters or characters), is construct automa tically by using a light pen as input device through the Dictionary Generating Package. The input coded string to the system may have a character code or a format control code which specifies the scale fa ctor of the Chinese character retrieved or the spacing control betwe en characters. By extending the presented text-editing systeem,it is estimated that a mini-computer of 32K 18-bit word main memory with a moderate disk memory is large enough for a processing system for a large set of Ch inese characters. In order to automate the publishing industry, in addition to the tex t-editing operation, the problem of automated typesetting should be solved. The arrangement of several paragraphs into a given page so that they are easily readable and space is utilized economically is a typesetting problem. It involves the problem of available space tr acking and space distribution. The tracking problem concerns which part of the page is available for typesetting and which part is conn ected to other parts of the page. The space distribution problem con cerns how to distribute the remaining space into other parts of the page. To study the automation of the typesetting process, a computer is used to simulate a fairly complicated typesetting process involve d in the typesetting operation of a daily newspaper. The simulating program is written in PL/I language. The result is included, and the technique for distributing blank space to titles is discussed.
