In 2010, Thomson Reuters released WestlawNext powered by WestSearch, a novel and proprietary algorithm. WestlawNext represents a new approach to legal research platform design. This article empirically examines the differences in search results using Westlaw Classic and WestlawNext by testing law students and librarians in both systems. Results demonstrate that researchers complete everyday searches faster and more accurately using WestlawNext. However, WestSearch's unique features and...

The article discusses the program "The New Generation of Legal Research Databases: Eighteen Months Later" at the February 27-March 1, 2011 Annual Meeting of the American Association of Law Libraries (AALL) Committee on Relations With Information Vendors (CRIV) in Philadelphia, Pennsylvania. The program speakers assessed the legal research database WestlawNext, especially in comparison to Westlaw Classic. Program speakers included librarians Jean P. O'Grady, Denise A. Pagh, and Lisa A. Spar.

Law students' practical ability to seek information by researching and to organize the complex layers of legal and non-legal information will not be enhanced without the law school's special efforts to provide pedagogies of practice in their remaining two years. In other words, the lack of more practical pedagogy prevents the law students from changing and extending their cognitive maps until they have a real job, where they do research, draft documents, advocate and counsel, and negotiate....

In 2002 Sweet & Maxwell began a long term project to apply a controlled vocabulary to their products, both in print and online. This vocabulary is essentially a thesaurus, structured on the principles of facet analysis, called the Legal Taxonomy. Sweet & Maxwell produce a wide range of legal publications that attempt to cover the gamut of a lawyer’s information sources. As everybody working in legal information knows, very few of a lawyer’s information needs will be met by reference to just...

La collaboration et le contenu généré par les usagers, aussi appelé « Web 2. 0 », sont des phénomènes nouveaux, qui bâtissent sur l'ouverture et le foisonnement d'Internet. Les environnements numériques qui emploient ces moyens mettent à contribution la communauté qui gravite autour d'une présence virtuelle afin d'en enrichir l’expérience. Suivant une approche constructiviste, nous explorons commnent la collaboration peut servir les usagers d'une banque de donnée de jugements en accès libre...

With the emergence of Internet various institutions started making available important legal materials in centralized online databases. Depending on the previous classification of data, available resources, degree of disclosure, each organization adopts its own way to present materials online. Oftentimes institutions providing similar data organize it in different ways (different titles, categories, search criteria, search engines, websites etc.) Additionally, some may do it differently due...

This article by Rachel Brett of Lovells reports on the results of a survey into classification practice in law libraries carried out through the BIALL and LIS-Law mailing lists in March 2007. Major findings were that only three respondents did not use any form of subject classification. The most frequently used classification scheme was Moys, and the single largest grouping was the 40 respondents (40.8%) who used their own in-house classification schemes.

Information-seeking is important for lawyers, who have access to many dedicated electronic resources. However there is considerable scope for improving the design of these resources to better support information-seeking. One way of informing design is to use information-seeking models as theoretical lenses to analyse users’ behaviour with existing systems. However many models, including those informed by studying lawyers, analyse information-seeking at a high level of abstraction and are...

To help design an environment in which professionals without legal training can make effective use of public sector legal information on planning and the environment - for Add-Wijzer, a European e-government project - we evaluated their perceptions of usefulness and usability. In concurrent think-aloud usability tests, lawyers and non-lawyers carried out information retrieval tasks on a range of online legal databases. We found that non-lawyers reported twice as many difficulties as those...

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...

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.

"The aim of our research is the improvement of Boolean search with query expansion using lexical ontologies and user feedback. User studies strongly suggest that standard search techniques have to be improved in order to meet legal particularities. Query expansion can exploit the potential of linguistic knowledge and successful user behaviour. First tentative results show the feasibility of our approach. A first search prototype has been built and tested in the area of European state aid law."

Knowledge Discovery from Legal Databases is the first text to describe data mining techniques as they apply to law. Law students, legal academics and applied information technology specialists are guided thorough all phases of the knowledge discovery from databases process with clear explanations of numerous data mining algorithms including rule induction, neural networks and association rules. Throughout the text, assumptions that make data mining in law quite different to mining other data...
