搜索引擎盈利模式探析——以百度和Google为例

网络经济时代的来临促成了搜索引擎的诞生。搜索引擎在其发展过程中也在不断地探索着自己的盈利模式,并渐趋明朗。本文正是以百度和Google两大搜索引擎公司为例探析搜索引擎当前的主要盈利模式。     

浅谈搜索引擎——以谷歌、百度、Bing、雅虎为例

文章列举了四种搜索引擎,并从定义、比较利用和如何使用搜索引擎这几个角度做了一定的分析。     

中美政务服务资源的搜索引擎可见性研究——基于谷歌和百度对典型政务服务事项的搜索结果分析

【目的/意义】我国“互联网+政务服务”发展迅速,在线政务服务资源日益丰富,民众能否通过搜索引擎查 找到政务服务是影响在线政务服务平台成效的重要因素。政务服务资源搜索的主要目标是“查准”,研究提出关于 中美政务服务资源搜索引擎可见性的八个假设。【方法/过程】按照查找典型政务服务个人事项“申领机动车驾驶 证”和法人事项“注册有限责任公司”的需求构造中英文关键词,分别通过百度和谷歌,以定位到中国各省和美国各 州经济最发达城市为目标进行搜索实验,采集首页搜索结果并进行相关性评分。在此基础上进行搜索引擎搜索功 能的统计分析,用非参数检验验证假设。【结果/结论】研究认为搜索引擎理解政务服务词汇的能力直接影响了其搜 索水平,政务服务平台也可以通过搜索引擎优化提升可见性。【创新/局限】研究创新在于构建中英文关键词,直接 采集百度和谷歌的搜索结果进行跨国比较研究,突破了以往同类研究的宽度和深度;局限主要在于相关性判断存 在主观性和搜索对象的规模较小。

Review of “Search Engines: Information Retrieval in Practice” by Croft,Metzler and Strohman

Despite the common public use of Web search engines, their internal design details mostly remain as a black art. The speculation is that there is a significant knowledge gap between what is published by academia and what is guarded behind the doors of large-scale search companies. “Search Engines: Information Retrieval in Practice” is one of the few books that make an attempt to cover issues involved in search engine design and is probably the most comprehensive book published so far on this topic. Unfortunately, the book fails to be a complete search engine guide as its content is dominated by the topics from information retrieval, text processing, and statistics. More precisely, the focus of the book is biased towards the “search” rather than the “engines” as, in most places, discussions on effectiveness dominate those on efficiency by a great margin. However, the book stands as a very solid IR book.     

Capturing information on technology convergence,international collaboration,and knowledge flow from patent documents: A case of information and communication technology

In addressing persistent gaps in existing theories, recent advances in data-driven research approaches offer novel perspectives and exciting insights across a spectrum of scientific fields concerned with technological change and the socio-economic impact thereof. The present investigation suggests a novel approach to identify and analyze the evolution of technology sectors, in this case, information and communications technology (ICT), considering international collaboration patterns and knowledge flows and spillovers via information inputs derived from patent documents.The objective is to utilize and explore information regarding inventors’ geo-location, technology sector classifications, and patent citation records to construct various types of networks. This, in turn, will open up avenues to discover the nature of evolutionary pathways in ICT trajectories and will also provide evidence of how the overall ICT knowledge space, as well as directional knowledge flows within the ICT space, have evolved differently. It is expected that this data-driven inquiry will deliver intuitive results for decision makers seeking evidence for future resource allocation and who are interested in identifying well-suited collaborators for the development of potential next-generation technologies. Further, it will equip researchers in technology management, economic geography, or similar fields with a systematic approach to analyze evolutionary pathways of technological advancements and further enable exploitation and development of new theories regarding technological change and its socio-economic consequences.
