LitCovid-AGAC: cellular and molecular level annotation data set based on COVID-19.

Genomics Inform 2021 Sep 30;19(3):e23. Epub 2021 Sep 30.

Hubei Key Lab of Agricultural Bioinformatics, College of Informatics, Huazhong Agricultural University, 430070 Wuhan, China.

Currently, coronavirus disease 2019 (COVID-19) literature has been increasing dramatically, and the increased text amount make it possible to perform large scale text mining and knowledge discovery. Therefore, curation of these texts becomes a crucial issue for Bio-medical Natural Language Processing (BioNLP) community, so as to retrieve the important information about the mechanism of COVID-19. PubAnnotation is an aligned annotation system which provides an efficient platform for biological curators to upload their annotations or merge other external annotations. Read More

A review of drug knowledge discovery using BioNLP and tensor or matrix decomposition.

Genomics Inform 2019 Jun 27;17(2):e18. Epub 2019 Jun 27.

Hubei Key Laboratory of Agricultural Bioinformatics, College of Informatics, Huazhong Agricultural University, Wuhan 430070, China.

Prediction of the relations among drug and other molecular or social entities is the main knowledge discovery pattern for the purpose of drug-related knowledge discovery. Computational approaches have combined the information from different sources and levels for drug-related knowledge discovery, which provides a sophisticated comprehension of the relationship among drugs, targets, diseases, and targeted genes, at the molecular level, or relationships among drugs, usage, side effect, safety, and user preference, at a social level. In this research, previous work from the BioNLP community and matrix or matrix decomposition was reviewed, compared, and concluded, and eventually, the BioNLP open-shared task was introduced as a promising case study representing this area.

PMC text mining subset in BioC: about three million full-text articles and growing.

Bioinformatics 2019 09;35(18):3533-3535

National Center for Biotechnology Information (NCBI), U.S. Library of Medicine (NLM), National Institutes of Health (NIH), Bethesda, MD, USA.

Motivation: Interest in text mining full-text biomedical research articles is growing. To facilitate automated processing of nearly 3 million full-text articles (in PubMed Central® Open Access and Author Manuscript subsets) and to improve interoperability, we convert these articles to BioC, a community-driven simple data structure in either XML or JavaScript Object Notation format for conveniently sharing text and annotations.

Results: The resultant articles can be downloaded via both File Transfer Protocol for bulk access and a Web API for updates or a more focused collection. Read More

Department of Computer Science and Engineering, Korea University, 145 Anam-ro, Seongbuk-gu, Seoul, 02841 Korea and

Comprehensive knowledge of genomic variants in a biological context is key for precision medicine. As next-generation sequencing technologies improve, the amount of literature containing genomic variant data, such as new functions or related phenotypes, rapidly increases. Because numerous articles are published every day, it is almost impossible to manually curate all the variant information from the literature. Read More

Community challenges in biomedical text mining over 10 years: success, failure and the future.

Brief Bioinform 2016 Jan 1;17(1):132-44. Epub 2015 May 1.

One effective way to improve the state of the art is through competitions. Following the success of the Critical Assessment of protein Structure Prediction (CASP) in bioinformatics research, a number of challenge evaluations have been organized by the text-mining research community to assess and advance natural language processing (NLP) research for biomedicine. In this article, we review the different community challenge evaluations held from 2002 to 2014 and their respective tasks. Read More

Approximate subgraph matching-based literature mining for biomedical events and relations.

PLoS One 2013 17;8(4):e60954. Epub 2013 Apr 17.

National Center for Biotechnology Information, Bethesda, Maryland, United States of America.

The biomedical text mining community has focused on developing techniques to automatically extract important relations between biological components and semantic events involving genes or proteins from literature. In this paper, we propose a novel approach for mining relations and events in the biomedical literature using approximate subgraph matching. Extraction of such knowledge is performed by searching for an approximate subgraph isomorphism between key contextual dependencies and input sentence graphs. Read More

The Genia Event and Protein Coreference tasks of the BioNLP Shared Task 2011.

BMC Bioinformatics 2012 Jun 26;13 Suppl 11:S1. Epub 2012 Jun 26.

Database Center for Life Science, Research Organization of Information and Science, 2-11-16 Yayoi, Bunkyo-ku, Tokyo, Japan.

Background: The Genia task, when it was introduced in 2009, was the first community-wide effort to address a fine-grained, structural information extraction from biomedical literature. Arranged for the second time as one of the main tasks of BioNLP Shared Task 2011, it aimed to measure the progress of the community since 2009, and to evaluate generalization of the technology to full text papers. The Protein Coreference task was arranged as one of the supporting tasks, motivated from one of the lessons of the 2009 task that the abundance of coreference structures in natural language text hinders further improvement with the Genia task.

Concept annotation in the CRAFT corpus.

BMC Bioinformatics 2012 Jul 9;13:161. Epub 2012 Jul 9.

Department of Pharmacology, University of Colorado Anschutz Medical Campus, Aurora, CO, USA.

Background: Manually annotated corpora are critical for the training and evaluation of automated methods to identify concepts in biomedical text.

Results: This paper presents the concept annotations of the Colorado Richly Annotated Full-Text (CRAFT) Corpus, a collection of 97 full-length, open-access biomedical journal articles that have been annotated both semantically and syntactically to serve as a research resource for the biomedical natural-language-processing (NLP) community. CRAFT identifies all mentions of nearly all concepts from nine prominent biomedical ontologies and terminologies: the Cell Type Ontology, the Chemical Entities of Biological Interest ontology, the NCBI Taxonomy, the Protein Ontology, the Sequence Ontology, the entries of the Entrez Gene database, and the three subontologies of the Gene Ontology.

Deriving a probabilistic syntacto-semantic grammar for biomedicine based on domain-specific terminologies.

J Biomed Inform 2011 Oct 28;44(5):805-14. Epub 2011 Apr 28.

Department of Biomedical Informatics, Columbia University, New York, NY 10032, USA.

Biomedical natural language processing (BioNLP) is a useful technique that unlocks valuable information stored in textual data for practice and/or research. Syntactic parsing is a critical component of BioNLP applications that rely on correctly determining the sentence and phrase structure of free text. In addition to dealing with the vast amount of domain-specific terms, a robust biomedical parser needs to model the semantic grammar to obtain viable syntactic structures. Read More

Concept recognition for extracting protein interaction relations from biomedical text.

Genome Biol 2008 1;9 Suppl 2:S9. Epub 2008 Sep 1.

Center for Computational Pharmacology, University of Colorado School of Medicine, Aurora, Colorado 80045, USA.

Background: Reliable information extraction applications have been a long sought goal of the biomedical text mining community, a goal that if reached would provide valuable tools to benchside biologists in their increasingly difficult task of assimilating the knowledge contained in the biomedical literature. We present an integrated approach to concept recognition in biomedical text. Concept recognition provides key information that has been largely missing from previous biomedical information extraction efforts, namely direct links to well defined knowledge resources that explicitly cement the concept's semantics.
