北京海文电子信息系统公司在光盘电子出版技术领域具有多项突破。海文公司是从事中文信息处理的专业公司,其Quick全文检索系统享誉海内外,并拥有广大的用户群。其系统在95年的光盘出版时被多家采用,这也是海文公司首次进入光盘出版领域。 在95年的光盘出版后,海文公司针对海量资料的检索技术进行了改进,使得其系统在超大资料的数据库检索时,系统速度大幅度提高,并且不会随资料量的激增而使性能恶化。针对光盘较硬盘速度慢的特点,海文公司进行了长达一年的技术攻关,并在95年底取得了突破性的进展,在一张刻有全年的《新华社电讯稿》和全年的《解放军报》的光盘进行任意词检索,速度同将其放在硬盘上的检索速度完全相同,并且其平均检索时间只有二、三秒钟,速度之快令人吃惊。而这一突破,也使得“海文,文海捞针”离人们越来越近。
Beijing Haiwen Electronic Information System Company has a number of breakthroughs in the field of optical disc electronic publishing technology. Haiwen Company is a professional company engaged in Chinese information processing. Its Quick full-text search system enjoys a good reputation at home and abroad and has a large user base. Its system was adopted by a number of CD-ROMs in 1995. This is the first time that the company has entered the field of CD publishing. After the publication of the 95-year CD-ROM, the company has improved the search technology for massive data, making its system significantly faster when searching large databases, and it will not deteriorate performance as the amount of data increases. . Focusing on the characteristics of slower speeds of optical discs than on hard drives, Haiwen conducted a one-year technological breakthrough and achieved breakthrough progress at the end of 1995. The annual Xinhua News Agency Telegraph is available for one year and the whole year. The “Liberation Army Daily” CD-ROM searched for any word at the same speed as it was on the hard disk, and its average retrieval time was only two or three seconds. The speed was surprising. This breakthrough has also made the “Haiwen and Wenhai needles” getting closer and closer.
