Annotator in pipeline

2015
PMCID: 4301805
PMID: 25607983
DOI: 10.1371/journal.pone.0116040

[…] biomedical domain., using four established concept recognition systems and a standard method to build a ssc for phenotype-related concepts reaches in the best case a f1-measure of 33% if only ncbo annotator and ctakes are used for annotations. even if four systems are combined, the obtained ssc is limited to mostly annotations of these two concept recognition systems. however, the best […]

[…] accession number, and the annotation text (e.g., “[27::42] hp_0000110 ∣ renal dysplasia”)., besides releasing the gsc, the authors performed a comprehensive evaluation of three ner systems: the ncbo annotator [], the obo annotator [], and the bio-lark cr []. bio-lark cr, just like ihp, is a recognition system with the objective of identifying hpo entities, while the ncbo annotator and the obo […]

[…] informative. therefore, methods generating synonyms with a higher ic score will have a major impact at the concept recognition task and so, document retrieval., the evaluation process used the obo annotator [], a concept recognizer oriented to perform automatic annotation of phenotypes based on the hpo. the following provides a brief overview of how the obo annotator works. first, it splits […]

[…] we investigate the performance of four extant concept recognition tools: the clinical text analysis and knowledge extraction system (ctakes), the national center for biomedical ontology (ncbo) annotator, the biomedical concept annotation system (becas) and metamap. each of the four concept recognition systems is applied to four different corpora: the i2b2 corpus of clinical documents, […]

[…] safety profiling of a drug, learning adverse drug–drug interactions, and learning used-to-treat relationships between drugs and indications., materials we first benchmarked the accuracy of the ncbo annotator and reveal in a manually annotated, publically available dataset from the 2008 i2b2 obesity challenge. we then applied the ncbo annotator and reveal to 9 million clinical notes […]

[…] the gender split is roughly 60% female, 40% male. ages range from 0 to 90 (adjusted to satisfy hipaa requirements), with an average age of 44 and standard deviation of 25., we created a standalone annotator workflow (figure ) based upon the existing national center for biomedical ontology (ncbo) annotator web service [] that annotates clinical text from electronic health record systems […]
