Abbreviations are common in clinical documentation, as this type of text is written under time-pressure and serves mostly for internal communication. This study attempts to apply and extend existing rule-based algorithms that have been developed for English and Swedish abbreviation detection, in order to create an abbreviation detection algorithm for Swedish clinical texts that can identify and...

Design. Our method uses a statistical learning algorithm, logistic regression, to score abbreviation expansions based on their resemblance to a training set of human-annotated abbreviations. We applied it to Medstract, a corpus of MEDLINE abstracts in which abbreviations and their expansions have been manually annotated. We then ran the algorithm on all abstracts in MEDLINE, creating a dictiona...

This study was conducted to evaluate protective efficiency of three different protocols for vaccination in canine heartworm infection. To evaluate the three protocols of immunization, dogs were separately immunized with living larvae; 1) immunization with gamma-attenuated infective larvae, 2) with 50 micrograms/kg ivermectin-abbreviation, and 3) with chemical abbreviation plus Freund's complete...

Essential information relevant to medical problems, tests, and treatments is often expressed in patient clinical records with natural language, making their processing a daunting task for automated systems. One of the steps towards alleviating this problem is concept extraction. In this work, we proposed a machine learning-based named entity recognition system to extract clinical concepts from ...

BioC is a recently created XML format to share text data and annotations, and an accompanying input/output library to promote interoperability of data and tools for natural language processing of biomedical text. This article reports the use of BioC to address a common challenge in processing biomedical text information-that of frequent entity name abbreviation. We selected three different abbr...

We propose that, by financing their own product sales through captive finance subsidiaries, durable goods manufacturers commit to higher resale values for their products in future periods. Using data on captive financing by the manufacturers of heavy equipment, we find that captive backed models have lower price depreciation. The evidence is consistent with captive finance helping manufacturers...
