Abstract

Document keyphrases provide a concise summary of a document's content, offering semantic metadata summarizing a document. They can be used in many applications related to knowledge management and text mining, such as automatic text summarization, development of search engines, document clustering, document classification, thesaurus construction, and browsing interfaces. Because only a small portion of documents have keyphrases assigned by authors, and it is time-consuming and costly to manually assign keyphrases to documents, it is necessary to develop an algorithm to automatically generate keyphrases for documents. This paper describes a Keyphrase Identification Program (KIP), which extracts document keyphrases by using prior positive samples of human identified phrases to assign weights to the candidate keyphrases. The logic of our algorithm is: The more keywords a candidate keyphrase contains and the more significant these keywords are, the more likely this candidate phrase is a keyphrase. KIP's learning function can enrich the glossary database by automatically adding new identified keyphrases to the database. KIP's personalization feature will let the user build a glossary database specifically suitable for the area of his/her interest. The evaluation results show that KIP's performance is better than the systems we compared to and that the learning function is effective.

Abstract

This article describes in detail the management of a Resource Description and Access (RDA) implementation process by an academic library that was an early adopter of RDA. It identifies the necessary decisions to be made and discusses the rationale behind these decisions during the implementation process. This information can benefit other libraries with managing their local RDA implementations. The authors examine the business case behind implementation from various perspectives such as administrative support, training, documentation, establishment of local procedures and costs. It aims to help cataloging/technical services/metadata managers understand the scope of the process and the impact it will have on their libraries.

Abstract

The organisation of knowledge for exploitation and re-use in the modern enterprise is often a most perplexing challenge. The entire knowledge management life-cycle (for example - create, capture, organize, store, search, and transfer) is impacted by the organisation of intellectual capital into a corporate taxonomy or at the least a knowledge map (often incorrectly used interchangeably). Determining the extent to which such an objective is achieved is the focus of what is known as a knowledge audit. In this practice-oriented article, the authors review the fundamentals of creating a taxonomy, the use of metadata in a necessary process known as classification and the role of expertise locators where the knowledge is not explicit but resides within experts in the form of tacit knowledge. The authors conclude with a framework for developing a corporate taxonomy and how such a project may be executed. The conceptual contribution of this article is the postulation that corporate taxonomies that are designed to facilitate knowledge audits lead to greater organizational impact.

Abstract

This paper describes high-quality journals in Brazil and Spain, with an emphasis on the distribution models used. It presents the general characteristics (age, type of publisher, and theme) and analyzes the distribution model by studying the type of format (print or digital), the type of access (open access or subscription), and the technology platform used. The 549 journals analyzed (249 in Brazil and 300 in Spain) are included in the 2011 Web of Science (WoS) and Scopus databases. Data on each journal were collected directly from their websites between March and October 2012. Brazil has a fully open access distribution model (97%) in which few journals require payment by authors thanks to cultural, financial, operational, and technological support provided by public agencies. In Spain, open access journals account for 55% of the total and have also received support from public agencies, although to a lesser extent. These results show that there are systems support of open access in scientific journals other than the "author pays" model advocated by the Finch report for the United Kingdom.
