Most text classification techniques assume that manually labeled documents (corpora) can be easily obtained while learning text classifiers. However, labeled training documents are sometimes unavailable or inadequate even if they are available. The goal of this article is to present a self-learned approach to extract high-quality training documents from the Web when the required manually labeled documents are unavailable or of poor quality. To learn a text classifier automatically, we need...

Users of search engines express their needs as queries, typically consisting of a small number of terms. The resulting search engine query logs are valuable resources that can be used to predict how people interact with the search system. In this paper, we introduce two novel applications of query logs, in the context of distributed information retrieval. First, we use query log terms to guide sampling from uncooperative distributed collections. We show that while our sampling strategy is at...

Geraldine Beare explores the history of indexing from its very earliest days, through the invention of the alphabet and the concept of alphabetical order to today’s world of Google and the search engine.

Accurate topical classification of user queries allows for increased effectiveness and efficiency in general-purpose Web search systems. Such classification becomes critical if the system must route queries to a subset of topic-specific and resource-constrained back-end databases. Successful query classification poses a challenging problem, as Web queries are short, thus providing few features. This feature sparseness, coupled with the constantly changing distribution and vocabulary of...

Purpose – This paper aims to provide an overview of principles and procedures involved in creating a faceted classification scheme for use in resource discovery in an online environment. Design/methodology/approach – Facet analysis provides an established rigorous methodology for the conceptual organization of a subject field, and the structuring of an associated classification or controlled vocabulary. This paper explains how that methodology was applied to the humanities in the FATKS...

The renaissance of interest in American legal history has been greatly aided by a variety of developments in the materials and methods of legal research. Legal history has become a new center of attention in American legal education and scholarship and has attracted similarly enhanced interest in university history departments. Fortunately, this comes at a time when increasingly sophisticated research techniques and sources are gaining wide acceptance in both the academic and legal communities. Professor Cohen surveys the effects of these advances on research in American legal history.

In revisiting their Stanford Law Review article, “Why Do We Tell the Same Stories: Law Reform, Critical Librarianship, and the Triple Helix Dilemma,” Professors Delgado and Stefancic contend that computer-assisted legal research has not proven to be a boon to the cause of law reform. At the time of the first article, the computer revolution, which irreversibly changed how we research legal questions, was just dawning. In this article, they focus again on categorical thinking, but this time...

The modern American law school curriculum is the product of a few but critical choices of design, some of them over a century old. In this Article, I seek to (1) outline how the basic structure and content of the modern American law school curriculum came into being and what were the main competitors that curriculum displaced; (2) describe some of the ways in which the curriculum's basic structure and content have changed since its inception; and (3) point to some of the main sources and motors of change.

Recording search histories, presenting them to the searcher, and building additional interface tools on them offer many opportunities for supporting user tasks in information seeking and use. This study investigated the use of search history information in legal information seeking. Qualitative methods were used to explore how attorneys and law librarians used their memory and external memory aids while searching for information and in transferring to information use. Based on the findings,...

Helmut Zedelmaier explores the early encyclopaedia as knowledge management tool, and the part played in its development by the index, discusses the role of the printing press in the development of the index, asks why the index declined in the 18th century, and identifies topics for consideration when some future history of the book index comes to be written. This article was translated by Andrew Horne.

The field of Information Science is constantly changing. Therefore, information scientists are required to regularly review—and if necessary—redefine its fundamental building blocks. This article is one of a group of four articles, which resulted from a Critical Delphi study conducted in 2003–2005. The study, “Knowledge Map of Information Science,” was aimed at exploring the foundations of information science. The international panel was composed of 57 leading scholars from 16 countries, who...
