A quick guide to large-scale genomic data mining.

PLoS Computational Biology, 2010
For the first several hundred years of research in cellular biology, the main bottleneck to scientific progress was data collection. Our newfound data-richness, however, has shifted this bottleneck from collection to analysis [1]. While a variety of options exists for examining any one experimental dataset, we are still discovering what new biological ...

Large scale chemical patent mining with UIMA and UNICORE [PDF]

Journal of Cheminformatics, 2012
Finding information about annotated chemical reactions for drugs and small compounds is a crucial step for pharmaceutical industries. This data often is presented in form of unstructured documents (especially patents) and manual extraction of this information is a time- and cost inefficient effort.

Artisanal-small Scale Mining in Myanmar

Applied Environmental Research, 2014
In many parts of the world, artisanal or small-scale mining activities are at least as important as large-scale mining activities. The numbers of people employed are actually considerably greater than in large companies. In 2002, an estimated 13 million

Large Scale Mining of Molecular Fragments with Wildcards [PDF]

Intelligent Data Analysis, 2003
The main task of drug discovery is to find novel bioactive molecules, i.e., chemical compounds that, for example, protect human cells against a virus. One way to support solving this task is to analyze a database of known and tested molecules with the aim to build a classifier that predicts whether a novel molecule will be active or inactive, so that ...
