How To Kill Inventors: Testing The Massacrator© Algorithm For Inventor Disambiguation
Inventor disambiguation is an increasingly important issue for users of patent data. We propose and test a number of refinements to the Massacrator© algorithm, originally proposed by Lissoni et al. (2006) and now applied to APE-INV, a free access database funded by the European Science Foundation. Following Raffo and Lhuillery (2009) we describe disambiguation as a 3-step process: cleaning&parsing, matching, and filtering. By means of sensitivity analysis, based on MonteCarlo simulations, we show how various filtering criteria can be manipulated in order to obtain optimal combinations of precision and recall (type I and type II errors). We also show how these different combinations generate different results for applications to studies on inventors\' productivity, mobility, and networking. The filtering criteria based upon information on inventors\' addresses are sensitive to data quality, while those based upon information on co-inventorship networks are always effective. Details on data access and data quality improvement via feedback collection are also discussed.
