Automatic document categorization is an important research problem in Information Science and Natural Language Processing. Many applications, including Word Sense Disambiguation and Information Retrieval in large collections, can benefit from such categorization. This paper focuses on automatic categorization of documents from the biomedical literature into broad discipline-based categories. Tw...

The h-index has been shown to increase in many cases mostly because of citations to rather old publications. This inertia can be circumvented by restricting the evaluation to a citation time window. Here I report results of an empirical study analyzing the evolution of the thus defined timed h-index in dependence on the length of the citation time window. 1. Introduction A recently popular meas...

Scientific publishing is rapidly developing from print-only to digital journals and extensive use of social media. This essay presents our experience in developing a small and scholarly journal from the so-called scientific semi-periphery and using the advantages of digital publishing to increase the visibility of the journal in international indexing and citation databases, and ensure greater ...

Introduction The use of inconsistent and outdated information may significantly compromise healthcare decision-making. We aimed to assess the extent lag times in publication indexing network meta-analyses (NMAs). Methods Searches for NMAs on drug interventions were performed PubMed (May 2020). Lag measured as time between last systematic search date article's submission, acceptance, online publ...

Journals in the " Information Science and Library Science " category of Journal Citation Reports (JCR) were compared using both bibliometric and bibliographic features. Data collected covered: journal impact factor, number of issues per year, number of authors per paper, longevity, editorial board membership, frequency of publication, number of databases indexing the journal, number of aggregat...

A JDI (Journal Descriptor Indexing) tool has been developed at NLM that automatically categorizes biomedical text as input, returning a ranked list, with scores between 0-1, of either JDs (Journal Descriptors, corresponding to biomedical disciplines) or STs (UMLS Semantic Types). Possible applications include WSD (Word Sense Disambiguation) and retrieval according to discipline. The Lexical Sys...

OBJECTIVES This study analyzes and describes the literature of addictions treatment and indexing coverage for core journals in the field. METHODS Citations from three source journals for the years 2008 through 2010 were analyzed using the 2010 Mapping the Literature of Nursing and Allied Health Professions Project Protocol. The distribution of cited journals was analyzed by applying Bradford'...

The National Library of Medicine (NLM), part of the National Institutes of Health in Bethesda, Maryland, is the world’s largest medical library. In 1879, NLM began publishing Index Medicus, a unified international database of biomedical literature. Index Medicus has since evolved into MEDLINE, an online electronic database searchable by using PubMed; it remains the world’s most important index ...
