The phrase “Big Data” is generally used to describe a large volume of structured and/or unstructured data that cannot be processed using traditional database and software techniques. In the domain of chemistry the Royal Society of Chemistry certainly hosts large structured databases of chemistry data, for example ChemSpider, as well as unstructured content, in the form of our collection of scientific articles. Our research literature provides value to their readership and, at present, as an example of one of our databases, ChemSpider is accessed by many tens of thousands of scientists every day. But do these collections constitute “Big Data” or is it the potential which lies within the collections that can contribute to the Big Data movement. This presentation will discuss our activities to contribute both data, and service-based access to our data sets, to support grant-based projects such as the Innovative Medicines Initiative Open PHACTS project (to support drug discovery) and the PharmaSea initiative (to identify novel natural products from the ocean). We will also provide an overview of our activities to perform data mining of public patent collections and examine what can be done with the data. We are presently extracting physicochemical properties and textual forms of NMR spectra and, with the resulting data, are building predictive models (for melting points at present) and assembling a large NMR spectral database containing many hundreds of thousands of spectral-structure pairs. Our experiences to date have demonstrated that we are working at the edge of current algorithmic and computing capabilities for predictive model building, with over a quarter of a million melting points producing a matrix of over 200 billion descriptors. Our work to produce the NMR spectral database will necessitate batch processing of the data to examine consistency between the spectral-structure pairs and other forms of data validation. The intention is to take our experiences in this work applied to a public patents corpus and apply it to the RSC back file of publications to mine data and enable new paths to the discoverability of both data and the associated publications.
