基于觅食理论的网络信息环境实证分析

An Empirical Analysis of Network Information Environment Based on Foraging Theory

通过对信息觅食理论的介绍，展现了一种不同于传统理论的、用于分析网络信息环境的思路和方法。在传统理论模型缺乏定量分析的情况下，本文从一种全新的角度来展示和描述用户的信息觅食行为与所处信息环境之间的关系，通过实证分析展示了信息觅食模型的核心思想和分析步骤。实验中，首先分析了该实验所处的信息环境，然后利用生成系统模型分析了该实验用户的信息觅食行为，最后构建了数学模型，并用模型展示了一种较理想的信息觅食方法。结论认为，信息觅食理论为网络环境下的信息查寻行为提供了一一个新的研究路径和分析方法。

The author analyzes the significance of information foraging theory, shows a different research perspective from traditional theory which lacks quantitative analysis of the relationship between user＇ s information foraging behavior and information environment. At last, we analyze a task of finding a good, reasonably priced hotel using the World Wide Web. First, we analyze the information environment of the task, and then we use production system models to show each production rule of the task, at last based on the optimal foraging theory, we use basic probability theory to illustrate the expected value of searching for better hotel prices. The result shows that information foraging theory＂ provides a new way of analyzing the information seeking and retrieval behavior under network environment.
