چکیده
Identification of the certainty of events is an important text mining problem. In particular, biomedical texts report medical conditions or findings that might be factual, hedged or negated. Identification of negation and its scope over a term of interest determines whether a finding is reported and is a challenging task. Not much work has been performed for Spanish in

Creation of an Annotated Corpus of Spanish Radiology Reports
This paper presents a new annotated corpus of 513 anonymized radiology reports written in Spanish. Reports were manually annotated with entities, negation and uncertainty terms and relations. The corpus was conceived as an evaluation resource for named entity recognition and relation extraction algorithms, and as input for the use of supervised methods. Biomedical annotated resources are scarce...

متن کاملResearch Paper: A Novel Hybrid Approach to Automated Negation Detection in Clinical Radiology Reports
OBJECTIVE Negation is common in clinical documents and is an important source of poor precision in automated indexing systems. Previous research has shown that negated terms may be difficult to identify if the words implying negations (negation signals) are more than a few words away from them. We describe a novel hybrid approach, combining regular expression matching with grammatical parsing, ...
متن کاملNegBio: a high-performance tool for negation and uncertainty detection in radiology reports
Negative and uncertain medical findings are frequent in radiology reports, but discriminating them from positive findings remains challenging for information extraction. Here, we propose a new algorithm, NegBio, to detect negative and uncertain findings in radiology reports. Unlike previous rule-based methods, NegBio utilizes patterns on universal dependencies to identify the scope of triggers ...
متن کاملImplementation and Evaluation of Four Different Methods of Negation Detection
Negation status identification for findings or diagnoses is an important medical data mining problem. Negative qualifier assigned to a medical condition may indicate the absence of the condition, so the ability to reliably identify the negation status of medical concepts affects the quality of results produced by the indexing and search tools. Searching for the best negation algorithm to use in...
