十多年前,张琪玉先生抓住“检索效率”这个核心问题,改造了旧的分类学和情报检索理论,创建了情报检索语言理论领域。以效率为核心是一种理论观,也是最符合现代社会科学发展趋势的理论观。张琪玉先生抓住了它,才使得情报检索语言理论成为我国图书馆学过去十多年里最引人注目的学科。 More than a decade ago, Mr. Zhang Qiyu seized the core issue of “retrieval efficiency,” transformed the old taxonomy and information retrieval theories and created the field of information retrieval language theory. Taking efficiency as the core is a theoretical view, which is also the most appropriate theoretical view of the development trend of modern social science. Zhang Qiyu caught it before making the theory of information retrieval language library science in our country more than a decade the most eye-catching subjects.
