Bio Saga Blog - A Chronicle of Life Sciences & Informatics

"There does appear to be a distinction between the way curation is used in the bio-sciences, and elsewhere. In particular, the term "curated database" tends to mean a manually constructed database that links literature to data, curated by experts who provide authority (eg see the Wikipedia definition of Biocurator ). The earliest mention of the term "curated database" I can find is in the abstract (and only in the abstract) of Larsen et al (1993)." Chris Rusbridge Digital Curation Blog Since these database are hand curated by experts (manually curated), they always promise a accuracy & quality better than uncurated or NLP based databases. While NLP based databases follow a automated curation provide quick updates and tend to be large in terms of the quantum of data. While they may trade off in accuracy due to their automated curation process. While platforms like XTractor Premium follow a unique approach by trying to adopt the best of both worlds. A ...

XTractor Knowledgebase XTractor is the first of its kind web 2.0 application which enables researchers to analyze the most current complex biological and chemical relationships published in PUBMED everyday. XTractor Knowledgebase now contains more than 100000 relationships on interactions, regulations and modulations between proteins, drugs, processes and disease. It is the only knowledgebase that updates its data content on a daily basis. The Approach: The Data behind XTractor comes from manual annotation, which is carried out by qualified scientists at Molecular Connections, INDIA ( www.molecularconnections.com ). Our scientists regularly handpick and annotate the most relevant sentences to public ontologies. Each of the data points is quality checked to ensure the highest levels of data accuracy. The extracted facts are also referenced back to the PubMed abstract(s).The sentences in XTractor are also manually c...
