Brian E. Chapman, Sean Lee, Hyunseok Peter Kang, Wendy W. Chapman
2011 Journal of Biomedical Informatics  
In this paper we describe an application called peFinder for document-level classification of CT pulmonary angiography reports. peFinder is based on a generalized version of the ConText algorithm, a simple  ...  text processing algorithm for identifying features in clinical report documents. peFinder was used to answer questions about the disease state (pulmonary emboli present or absent), the certainty state  ...  peFinder: a pyConText-based classifier for CTPA reports To identify CTPA reports that describe the presence of an acute pulmonary embolism from an exam of high diagnostic quality, we developed a document-level  ...

2014 Journal of Biomedical Informatics  
In this paper we describe an efficient tool based on natural language processing for classifying the detail state of pulmonary embolism (PE) recorded in CT pulmonary angiography reports.  ...  The classification tasks include: PE present vs. absent, acute PE vs. others, central PE vs. others, and subsegmental PE vs. others.  ...  An information theory-based algorithm was validated on radiology reports [28] .  ...
