Data for Science: How Elsevier is using data science to empower researchers

1. DATA FOR SCIENCE HOW ELSEVIER IS USING DATA SCIENCE TO EMPOWER RESEARCHERS Paul Groth | @pgroth | pgroth.com Disruptive Technology Director Elsevier Labs | @elsevierlabs European Data Forum 2016
2. 12 million people per month
3. 40 million reactions 75 million compounds 500 million facts
4. 3 EXAMPLES • Personalized: what should I read? • Actionable: who should I collaborate with? • Consumable: how do I make my data available?
5. RECOMMENDATIONS AT MENDELEY • Maya Hristakeva • Data Scientist at Mendeley • @mayahhf • Spark Summit 2015 • http://www.slideshare.net/SparkSummit/sparkin g-science-up-with-research-recommendations- by-maya-hristakeva
6. Read & Organize Search & Discover Collaborate & Network Experiment & Synthesize MENDELEY BUILDS TOOLS TO HELP RESEARCHERS …
7. BEING THE BEST RESEARCHER YOU CAN BE! • Good researchers are on top of their game • Large amount of research produced • Takes time to get what you need • Help researchers by recommending relevant research
8. PERSONALIZED ARTICLE RECOMMENDATION Input: User libraries Output: Suggested articles to read Algorithms: • Collaborative Filtering – Item-based – User-Based – Matrix Factorization • Content-based
9. Costly & GoodCostly & Bad Cheap & GoodCheap & Bad Tuned IB Mahout Tuned UB Mahout Tuned UB Spark Tuned IB Spark UB DimSum Spark MLlib ALS Matrix Fact. Spark MLlib Performance +100% +150% ~$50
10. CALCULATING 75 TRILLION METRICS • Benchmark 4600 institutions & 220 countries updated weekly • 40 terabytes of data • HPCC massively parallel compute system – 40 node system
11. ALL DATA ISN’T CURATED
12. 60 % OF TIME IS SPENT ON DATA PREPARATION

14. http://data.mendeley.com/ Each dataset receives a versioned DOI, so it can be cited The citation for the associated article is displayed
15. ACADEMIC COLLABORATIONS
16. CONCLUSION • Researchers are faced with an ever growing amount of data and content • Data Science is key to making systems that help them • I’ve shown three Elsevier examples. Many more! • Antonio Gulli’s codingplayground.blogspot.nl • labs.elsevier.com • Of course, we’re hiring  Contact: Paul Groth @pgroth

1.8 million unique authors worldwide submitted 1.3 million manuscripts to Elsevier journals
40 million reactions
75 million compounds
500 million experimental facts ,
At Mendeley we build tools to help researchers organise and read research articles, collaborate and connect with other researchers, search and discover new research articles, etc.
815 million articles
“Mendeley Suggest” is our personalised article recommender. It is based on what users have in their libraries, and recommends other related articles.
Calculate for over 4 million users

We are building a personalised article recommender based on what users read. Input is the users’ libraries and the output is a list of articles they may want to add to their library and read. There are a number of different algorithms we can use to generate the recommendations (content-based, collaborative filtering), and this talk we’ll focus on three types of collaborative filtering algorithms (user and item-based as well as matrix factorisation).
To sum, we now have a Spark implementation of our production UB CF algorithm which performs well, and is a lot simpler to maintain and extend. There are still a few areas where we can tune and optimise further, so that could only make it faster and get bigger gains of using Spark. Depending on your data different algorithms might work better, so do experiment.
