Construction of a Portal Site for Gender Studies using a Diachronic Analysis Method of Web Communities

Web挖掘是现代信息技术领域的重要研究课题之一。在Web挖掘技术中，Web结构挖掘是发现Web社区的关键技术。已经开发了各种挖掘算法和工具来查找Web社区。在本研究中，我们关注了基于hits的Web结构挖掘工具“Companion”，它能够提供Web社区的历时性和共时性分析。历时分析的能力是必不可少的，特别是当一个挖掘工具被应用于调查一个Web社区时，比如与性别相关的社区，它会随着社会文化和政治的变化而随着时间的推移而急剧变化。在这项研究中，我们首先观察到现实世界社区（即组织及其成员）的变化如何在Web上反映为Web社区的变化。其次，我们分析了与性别相关的网络社区，以发现新的趋势或运动，这些趋势或运动很难通过一个能够进行历时分析的挖掘工具来识别。最后，我们调查了一个需要矿工解密能力的案例。基于以上结果，我们在御茶水大学性别研究所建立了一个“性别研究门户网站”。通过分析围绕“性别”这个关键词在网络上构建的网络社区，我们试图获得只有在网络上才能观察到的社会性别现象的新概念。使用Companion-作为网络挖掘工具，研究了通过搜索词“ender”提取的与性别相关的社区的发展。这种方法使我们能够主观上和客观地考察性别群体，实际上是感知到一种迄今为止尚未认识到的现象。此外，由于性别专家对网络社区的发展过程进行了彻底的审查，因此本分析就其研究结果的意义性质而言提供了一个积极的例子。换句话说，我们能够验证纹理化的显示器，乍一看似乎毫无意义，成为一个重要的和具有挑战性的空间，通过特定领域的专家的眼睛来破译（=分析）。该研究具体地证明了与熟悉内容现实的特定领域的研究人员合作在促进开发适当的Web挖掘工具方面的有效性和影响。这种与研究人员的对话只能使分析工具更加复杂。如果挖掘工具的功能得到改进，肯定有可能从它们的分析中找到更有趣的结果类型。同时，我们也提醒，如果没有认真考虑分析工具的特定倾向或特征，则检查研究可能存在缺陷。对于这种检查，对“分析工具”本身的反思总是必要的。少

Web mining is one of the most important research issues in modern information technology. Among Web mining techniques, the Web structure mining is essential to find Web communities. A variety of mining algorithms and tools have been developed for finding Web communities. In this research, we paid attention to the HITS-based Web structure mining tool "Companion", which was able to provide diachronic as well as synchronic analysis of Web communities. The capability of diachronic analysis was essential, particularly when a mining tool was applied to investigate a Web community-like the gender-related community-that changes shape dramatically over time according to socio-cultural and political changes. In this research we first observed how changes in the real world communities, i.e. organizations their members, could be reflected on the Web as changes in Web communities. Second, we analyzed gender-related Web communities to discover new trends or movements that were hard to identify witho … More ut a mining tool capable of diachronic analysis. Last, we investigated a case that calls for the deciphering capability of miners. Based on the above results, we constructed a "portal site for gender studies" in the Institute for Gender Studies of Ochanomizu University.By analyzing the Web communities constructed around the keyword "gender" on the Web, we have attempted to gain new conceptions of societal gender phenomena, available for observation only on the Web. Using Companion- as a Web mining tool, the research examines the development of genderrelated communities extracted through the search term "ender." This method enabled us to examine the gender communities subjectively as well as objectively, and in fact, to perceive a heretofore unrealized phenomenon. Plus, since the developmental process of the Web communities was examined thoroughly by gender specialists, the present analysis provided a positive example in terms of the meaningful nature of its findings. In other words, we were able to verify that the texturized displays, which seem nonsense at first glance, become a vital and challenging space to be deciphered (=analyzed) through the eyes of specialists of a particular field. The research concretely demonstrates the effectiveness and impact of collaborating with researchers of specific fields who are familiar with the reality of the contents in facilitating the development of appropriate Web mining tools. This kind of dialog with researchers can only make the analysis tool more sophisticated. If the functions of the mining tools improve, there is certainly the possibility of finding even more interesting types of results from their analyses. Simultaneously, we have cautioned that if particular tendencies or characteristics of the analysis tool are not seriously considered, the examination research may be flawed. Reflection upon the "analysis tool" itself is always necessary for such examinations. Less
