[…] (ner) of pharmacological substances, the best results were achieved by wbi_ner. this ner approach is formulated as a sequence labeling task (iob format). using domain‐independent features from chemspot, jochem, and chebi ontology, linear‐chain conditional random field model was implemented to predict the sequences of name entities. the second best method (nlm lhc) utilized dictionaries […]

[…] i trains a first-order crf using features from banner () plus further ones obtained through a trial-and-error procedure, including character n-grams, chemical specific identifiers, and the output of chemspot () (another high-quality chemical ner tool). the output of the model is filtered by several type-specific post-processing steps for abbreviation resolution, enforcing of tagging consistency […]

[…] the recognition of named entities of diseases is rather tougher than those of chemical names. although there are some remarkable chemical named entity recognition systems available online such as chemspot and tmchem, the publicly available recognition systems of disease named entities are rare. this article presents a system for disease named entity recognition (dner) and normalization.

[…] site. after constructing the dictionary, lingpipe [], a dictionary-based exact-matching ner tool, was applied to all collected abstracts to locate plant names. chemical names were annotated using chemspot [], which is a specialized tool for locating chemical names that covers trivial names, drugs, abbreviations, and molecular formulas in texts. for the annotation of chemical identifiers […]

[…] ner systems for scientific literature, by providing a large-scale standard corpus (). typical approaches applied to chemical ner in representative systems such as whatizit (), oscar3/4 (, ), chemspot () and tmchem () included dictionary lookup (), machine learning-based models (, , ) and hybrid methods that combined a dictionary with a machine learning-based classifier (). in addition […]
