摘要

Based on the results of Gregory B. Newby's experiment that an information space of an information system corresponds with the cognitive spaces of its human users, this article further explores the concept of information need. The assumption we explore here is that information needs may appear only when an individual has a partial knowledge of a term. We follow Newby's approach by constructing an information space with term cooccurence and cognitive spaces with term association using twelve terms in the area of Library and Information Science. When the spaces overlap we can get a similarity between term vectors in the information space and in the cognitive space. We assume that such similarity can show how much a human may know about the term. After analyzing the space, information needs are then identified and situated in a moderate similarity group of terms. Discussions about some considerations in methodology and in interpretation of the results are provided.

Newby）的实验结果，即信息系统的信息空间与其人类用户的认知空间相对应，本文进一步探讨了信息需求的概念。我们在这里探索的假设是，仅当个人对术语有一定了解时，才会出现信息需求。我们遵循纽比（Newby）的方法，通过使用图书馆和信息科学领域的十二个术语来构建一个带有术语共现的信息空间和带有术语关联的认知空间。当空间重叠时，我们可以在信息空间和认知空间中获得术语向量之间的相似性。我们假设这种相似性可以表明人们可能对该术语了解多少。在分析了空间之后，便确定了信息需求并将其放置在中等相似度的术语组中。提供了有关方法论和结果解释中一些注意事项的讨论。
