知识搜索的时间维度研究综述

Research review on time dimension of knowledge search

知识经济时代,时间已成为知识搜索战略的构成要素。综合以往与知识搜索的时间维度相关研究,围绕"搜索什么知识"、"何时搜索知识"及"如何搜索知识"三个主题展开研究,系统梳理了知识年龄及时序问题、知识搜索速度及时机问题、知识搜索的时间认知决策问题,在此基础上探讨上述三个方面主题的内在逻辑关系,并创新性地提出未来知识搜索时间维度研究的时间边界、时机选择、时间认知、时间演化等四个前沿问题。

In the era of knowledge economy,time has become a part of the knowledge search s trateg y. Based on previous studies related to the time dimension of knowledge se a rch, this paper focuses on three questions： “what to search”,“when to search” and ‘‘how to search”. The knowledge age and sequence, the speed and timing of knowledge sea rch, and temporal cognitive decision of knowledge search are systematically explored. On this b a s is, internal theoretical relationship of the three subject areas is discussed. Fin al ly, four frontier issues about the time dimension of knowledge search are put fo rw a rd, including temporal boundaries,search timing select ion,temporal cognition, and temporal evolution.
