This is my sixth presentation at the ACS Fall Meeting in Indianapolis:
Digitizing documents to provide a public spectroscopy database
RSC hosts a number of platforms providing free access to chemistry related data. The content includes chemical compounds and associated experimental and predicted data, chemical reactions and, increasingly, spectral data. The ChemSpider database primarily contains electronic spectral data generated at the instrument, converted into standard formats such as JCAMP, then uploaded for the community to access. As a publisher RSC holds a rich source of spectral data within our scientific publications and associated electronic supplementary information. We have undertaken a project to Digitally Enable the RSC Archive (DERA) and as part of this project are converting figures of spectral data into standard spectral data formats for storage in our ChemSpider database. This presentation will report on our progress in the project and some of the challenges we have faced to date.
This is ,y fourth talk at the ACS Indianapolis Conference:
Practical semantics in the pharmaceutical industry – the Open PHACTS project
The information revolution has transformed many business sectors over the last decade and the pharmaceutical industry is no exception. Developments in scientific and information technologies have unleashed an avalanche of content on research scientists who are struggling to access and filter this in an efficient manner. Furthermore, this domain has traditionally suffered from a lack of standards in how entities, processes and experimental results are described, leading to difficulties in determining whether results from two different sources can be reliably compared. The need to transform the way the life-science industry uses information has led to new thinking about how companies should work beyond their firewalls. In this talk we will provide an overview of the traditional approaches major pharmaceutical companies have taken to knowledge management and describe the business reasons why pre-competitive, cross-industry and public-private partnerships have gained much traction in recent years. We will consider the scientific challenges concerning the integration of biomedical knowledge, highlighting the complexities in representing everyday scientific objects in computerised form. This leads us to discuss how the semantic web might lead us to a long-overdue solution. The talk will be illustrated by focusing on the EU-Open PHACTS initiative (openphacts.org), established to provide a unique public-private infrastructure for pharmaceutical discovery. The aims of this work will be described and how technologies such as just-in-time identity resolution, nanopublication and interactive visualisations are helping to build a powerful software platform designed to appeal to directly to scientific users across the public and private sectors.
The future of scientific information & communication presented at the SUNY Potsdam Academic Festival
This is a LONG presentation….I talk about the “It’s All About Me” attitude that can positively feed science….we want to share OUR science, we want people to know about our opinions, our activities, our collaborators, we want to get funding, recognition and attribution. And why not…it can all be to the benefit of science.
This presentation was given at the SUNY Potsdam Academic Festival
The future of scientific information & communication
Our access to scientific information has changed in ways that were hardly imagined even by the early pioneers of the internet. The immense quantities of data and the array of tools available to search and analyze online content continues to expand while the pace of change does not appear to be slowing. While scientists now have access to the enormous capacities and capability of the internet the vast majority of scientific communication continues to be through peer-reviewed scientific journals. The measure of a scientist’s contribution is primarily represented by their publication profile and the citations to their published works and offers an incomplete view of their activities. However, we are at the beginning of a new revolution where the ability to communicate offers the opportunity to embrace new forms of publishing and where scientific participation and influence will be measured in new ways. This presentation will provide an overview of our new generation of “openness” in which open source, open standards, open access and open data are proliferating. The future of scientific information and communication will be underpinned by these efforts, influenced by increasing participation from the scientific community and facilitated collaboration and ultimately accelerate scientific progress.
This week/weekend I will attend the ScienceOnline2013 conference here in Raleigh, North Carolina. This is my favorite conference of the year, bar none. I feel privileged every time I attend to be surrounded by people who are challenging the status quo and are passionate about making science more available and consumable to their peers and the community. I have met some great people at this conference and every year I walk away tired yet invigorated. I walk away feeling that my own contributions to science, especially my work to enable access to chemistry data, is coherent with the efforts of many of the crowd attending this meeting. The meeting has a commitment to scientific truth, collaboration, communication and openness. YES!!!
While I am a chemist by training what I enjoy so much about the meeting is meeting NON-chemists and learning about their world, their interests, their adventures and challenges. By keeping my head in my own box at many other conferences, primarily chemistry of course, I limit what I can learn from the experiences outside of my domain. ScienceOnline frees me up from these boundaries by throwing me into a mix of wildly different engagement. It is, quite simply, a joy! And coming at the beginning of the year it is the first conference I attend…always good!
The conference is well organized, wall to wall entertainment in various forms (including science comedians!), is socially engaging (lots of opportunities for after hours play!) and is full of “my kind of people”. I am lucky to be so close and, this year, to be able to share space with one of my closest friends. Sean Ekins (@collabchem) and I will host a discussion on “Leading Chemists Into Openness“. Sean and I hung out at the conference last year and it had a good impact on him as he describes here.
If you are attending ScienceOnline2013, are interested in Open Science and the advantages, challenges and “unknowns” of how to get there, then please come and join the conversation. We are the hosts…you define where we go! The slides below are for you to review/consider/digest in advance of the session. See you there???!!!
There are a number of people in my domain that I have great appreciation for and that I enjoy working with. So, an opportunity to co-author on rules for licensing data with Sean Ekins and John Wilbanks was an opportunity too good to miss. There are a lot of opinions, rants and views on data licensing floating around the internet, discussed at conferences and over beverages. Meanwhile we have opinions too and have shared them through this perspective on PLoS Computational Biology through this paper: “Why Open Drug Discovery Needs Four Simple Rules for Licensing Data and Models”
When writing a publication how many of us conduct complete literature searches? For those of us who do not have access to Scifinder how are we finding our literature? Probably through Google Scholar? When I write a paper I admit that some of my searches may be less than complete but I do try and stay informed in regards to what is going on in my domain. VERY occasionally I get feedback from reviewers pointing me to references that they feel I either ignored or was unaware of. Many times they are co-authored by the reviewer themselves…and it is pretty easy to figure out who the reviewers are
Today I received an email in my inbox about the latest article in the Journal of Cheminformatics. It is OMG: Open Molecule Generator. The article is here. The abstract opens with “Computer Assisted Structure Elucidation has been used for decades to discover the chemical structure of unknown compounds. In this work we introduce the first open source structure generator, Open Molecule Generator (OMG), which for a given elemental composition produces all non-isomorphic chemical structures that match that elemental composition.”
Having been involved with Computer-Assisted Structure Elucidation for many years, having co-authored a book about it (here) and probably the definitive review article from the past 5 years (here) I would have assumed that our work would have been referenced. I was surprised to see that our work was not referenced while other CASE systems were. Articles we’ve issued over the past few years are below. I’ve gathered them here to point the authors to in case they want to reference any of them and missed them in the literatire search.
I am taking advantage of the fact that I can leave comments on the provisional manuscript here (what a great capability!!!) and will let them know about this list. it would be good to compare the performance of the OMG with the structure generator under ACD/Structure Elucidator sometime….

Second talk delivered today at ACS Philadelphia…
Mining public domain data as a basis for drug repurposing
Online databases containing high throughput screening and other property data continue to proliferate in number. Many pharmaceutical chemists will have used databases such as PubChem, ChemSpider, DrugBank, BindingDB and many others. This work will report on the potential value of these databases for providing data to be used to repurpose drugs using cheminformatics-based approaches (e.g. docking, ligand-based machine learning methods). This work will also discuss the potentially related applications of the Open PHACTS project, a European Union Innovative Medicines Initiative project, that is utilizing semantic web based approaches to integrate large scale chemical and biological data in new ways. We will report on how compound and data quality should be taken into account when utilizing data from online databases and how their careful curation can provide high quality data that can be used to underpin the delivery of molecular models that can in turn identify new uses for old drugs.
This is one of my presentations at the ACS meeting today in San Diego regarding how to use social networking tools to expose yourself as a scientist
Social networking tools as public representations of a scientist
The web has revolutionized the manner by which we can represent ourselves online by providing us the ability to exposure our data, experiences and skills online via blogs, wikis and other crowdsourcing venues. As a result it is possible to contribute to the community while developing a social profile as a scientist. At present many scientists are still measured by their contributions using the classical method of citation statistics and a number of freely available online tools are now available for scientists to manage their profile. This presentation will provide an overview of tools including Google Scholar Citations and Microsoft Academic Search and will discuss how these are and other tools, when integrated with the ORCID identifier, may more fully recognize the collective contributions to science. I will also discuss how an increasingly public view of us as scientists online will likely contribute to our reputation above and beyond citations.
This is my presentation at the InChI Symposium today:
The great promise of navigating the internet using InChIs
The InChI, the International Chemical Identifier, has been the basis of both indexing and deduplication of the ChemSpider database since the inception of the platform. When the InChI was adopted we envisaged a future whereby the identifier would proliferate across journals, databases and the internet in general providing us a basis for “structure searching the internet”. This presentation will provide an overview of how the InChI has facilitated the integration of ChemSpider to chemistry on the internet, some of the surprising findings that have resulted from this work and extrapolate the influence of InChIs into the future for a chemically enabled web.
This presentation was just given at the ACS meeting in San Diego…
The Royal Society of Chemistry hosts an online resource, ChemSpider, as a structure centric database for chemists linking over 25 million chemicals to 400 internet sites. As a crowdsourced environment members of the chemistry community can deposit spectral data to the database. Almost 2000 NMR spectra have been submitted to the database and these are the basis of both a gaming environment for learning NMR spectroscopy, the SpectralGame, as well as a new teaching environment known as SpectraSchool. This presentation will provide an overview of these two online resources and how they may be utilized for the purpose of teaching NMR spectroscopy in an Undergraduate Curriculum.
