Using Large Biomedical Databases as Gold Annotations for Automatic Relation Extraction

Tilia Ellendorff, Fabio Rinaldi, Simon Clematide
2014
We show how to use large biomedical databases in order to obtain a gold standard for training a machine learning system over a corpus of biomedical text.  ...  As an example we use the Comparative Toxicogenomics Database (CTD) and describe by means of a short case study how the obtained data can be applied.  ...  One very large database which is especially useful for biomedical relation extraction is the Comparative Toxicogenomics Database (CTD) (Davis et al., 2009 ).  ...

Knowledge-based extraction of adverse drug events from biomedical text

Ning Kang, Bharat Singh, Chinh Bui, Zubair Afzal, Erik M van Mulligen, Jan A Kors
2014 BMC Bioinformatics  
Many biomedical relation extraction systems are machine-learning based and have to be trained on large annotated corpora that are expensive and cumbersome to construct.  ...  Whether use of a knowledge base is equally advantageous for other biomedical relation-extraction tasks remains to be investigated.  ...  In recent years, many systems have been developed for the automatic extraction of biomedical events from text, such as protein-protein interactions and gene-disease relations [2, 6] .  ...

A multi-ontology approach to annotate scientific documents based on a modularization technique

Priscilla Corrêa e Castro Gomes, Ana Maria de Carvalho Moura, Maria Cláudia Cavalcanti
2015 Journal of Biomedical Informatics  
Text annotation may help as it relies on the use of ontologies to maintain annotations based on a uniform vocabulary.  ...  Based on these annotations a set of modules are extracted from a set of distinct ontologies, and are made available for the user, for complementary annotation.  ...  In this study, relevant requirements for biomedical text annotation, such as the support for manual and automatic annotation, and the flexibility for loading ontologies were observed.  ...
