Wikipedia authors cite external references to support claims made in their articles in order to increase their validity. A large number of claims, however, do not have supporting citations, putting them in question. In this paper, we describe a study in which we attempt to retrieve relevant citations for claims using a variety of information retrieval algorithms. These algorithms are inspired b...

A model is proposed for the creation and transmission of scientific knowledge, based on the network of citations among research articles. The model allows to assign to each article a nonnegative value for its creativity, i. e. its creation of new knowledge. If the entire publication network is truncated to the first neighbors of an article (the n references that it makes and the m citations tha...

This guideline is intended to aid the endoscopist in the management of adult patients with possible foreign object ingestion and/or food bolus impaction. A literature search was performed on the Medline using Medlars II, the National Library of Medicine's National Interactive Retrieval Service. This search generated 181 citations.

In this paper we show that the dramatic increase in the number of research articles indexed in the Web of Science database impacts the commonly observed distributions of citations within these articles. First, we document that the growing number of physics articles in recent years is due to existing journals publishing more and more papers rather than more new journals coming into being as it h...

The National Institutes of Health encourages its research partners to use VIVO software to enhance research investigator collaboration. VIVO provides a dynamic online directory to facilitate professional networking opportunities for investigators who share similar or complementary research interests (VIVO, 2015). VIVO Harvester performs author searches in PubMed to populate VIVO profiles with a...

With over 20 million records, the ADS citation database is regularly used by researchers and librarians to measure the scientific impact of individuals, groups, and institutions. In addition to the traditional sources of citations, the ADS has recently added references extracted from the arXiv e-prints on a nightly basis. We review the procedures used to harvest and identify the reference data ...
