  • Meta-tag: a means to control the process of Web indexing by Dariush Alimohammadi
    Search engines are used to locate information on the Web, but they cannot always adequately meet the information needs of users. Some schemes have been developed to solve this problem and meta-tags are one of them. This article provides a comprehensive definition of meta-tags and explains their function. Then, the possible attributes of meta-tags and the most important meta-tags are introduced in detail. It concludes that, although the meta-tag has shortcomings, as do other schemes of information organizing, it can help improve the retrievability of information on the Web, and should be utilized by Web masters and search engine designers.
  • Automatic query taxonomy generation for information retrieval applications by Shui-Lung Chuang; Lee-Feng Chien
    It is crucial for information retrieval systems to learn more about what users search for in order to fulfill the intent of searches. This paper introduces query taxonomy generation, which attempts to organize users' queries into a hierarchical structure of topic classes. Such a query taxonomy provides a basis for the in-depth analysis of users' queries on a larger scale and can benefit many information retrieval systems. The proposed approach to this problem consists of two computational processes: hierarchical query clustering to generate a query taxonomy from scratch, and query categorization to place newly-arrived queries into the taxonomy. The results of the preliminary experiment have shown the potential of the proposed approach in generating taxonomies for queries, which may be useful in various Web information retrieval applications.
