Negation detection is the task of identifying negation cues in text.
This paper presents an open-source toolkit for negation detection.
In the era of clinical information explosion, a good strategy for clinical text summarization is helpful to improve the clinical workflow.
Detecting negation and speculation in language has been a task of considerable interest to the biomedical community, as it is a key component of Information Extraction systems from Biomedical documents.
Speculation is a naturally occurring phenomena in textual data, forming an integral component of many systems, especially in the biomedical information retrieval domain.
