中文摘要 | 布拉德福-洛特卡-齊夫分佈是資訊分佈的重要規律,長期以來,學術界對此進 行了大量的研究,但對其內機制一直缺乏令人滿意的解釋。流行的「成功產生成功」和「省 力法則」兩說均未能提供令人信服的解釋。本文提出了資訊流的自組織原理,揭示了布-洛 -齊分佈的條件、過程、機理,對這一現象作出了全新的解釋。 |
英文摘要 | Bradford-Lotka-Zipf distribution is the most important rule of documentary information distribution. For a long time, a great deal of research had been carried out, but the explanations to this distribution are not satisfying. Two prevailing theories-success-breeds-success, saving effort rule-can not provide satisfactory explanation. This paper presents self organization principle of documentary information flow, reveals the condition, process, and rule of Bradford-Lotka-Zipf distribution. |
