August 2012 Applied scientometrics We are living in the age of Big Data −continuous increase in the amounts of data on science, technology and innovation −Web of Science c. 45 million scientific publications, PATSTAT c. 67 million patent applications, with detailed information on every record −enormous expansion of web data (e.g. twitter, blogs) −we now have the computer power to mine and analyse those data Increasing call for evidence-based policy −support policy and politics with reliable information −applied scientometrics can help understand the effects of policy Edwin Horlings | 4 / 28 | Patenting in the Netherlands

August 2012 Applied scientometrics Edwin Horlings | 5 / 28 | Patenting in the Netherlands Applying advanced quantitative methods to large heterogeneous datasets in order to extract patterns that show the structure and development of science, technology and innovation

August 2012 What sort of patterns do we look for? Networks −co-authors of scientific papers −inventors and assignees of patents −members of the same assocations −researchers working on or talking about the same topics Clustering of similar items −publications about the same topic or in the same specialisation −similar patents by different organisations −clusters in collaboration networks Statistical analysis of patterns (e.g. Social Network Analysis) Edwin Horlings | 6 / 28 | Patenting in the Netherlands

August 2012 SAINT Toolkit the Science Assessment Integrated Network Toolkit Main components at the moment −ISI Parser: convert raw Web of Science data into a relational database −Word Splitter: cuts full text into words, eliminating stop words, and shortening words to their stem using different algorithms −Network Tools: identify clusters in network using one of the best clustering algorithms (Blondel et al. 2008) Edwin Horlings | 8 / 28 | Patenting in the Netherlands

August 2012 SAINT Toolkit Under development −Integrating all tools into a Work Flow Manager −Word splitting using Natural Language Programming to extract terms rather than words −Adding alternative clustering algorithms for network analysis −Improve the Parser for new data sources, such as Scopus and online data −Develop tools for disambiguation of authors and addresses Edwin Horlings | 9 / 28 | Patenting in the Netherlands

August 2012 APPLICATIONS Edwin Horlings | 10 / 28 | Patenting in the Netherlands

August 2012 Author disambiguation Thousands of researchers with identical names (e.g. Y. Zhang): how to tell the difference? Important for evaluation and for research Developed an algorithm with % accuracy Now developing software tool with University of Paris Est (ESIEE) Edwin Horlings | 11 / 28 | Patenting in the Netherlands

August 2012 Portfolio of individual researchers Edwin Horlings & Thomas Gurney | 12 / 28 | Search strategies along the academic lifecycle How do individual researchers develop their scientific portfolio? −different stages in their career −different problem areas, often simultaneous −coherence of their portfolio −author position Developed a scientometric method to visualise and statistically analyse
