Abstract

Inventor name disambiguation is the task that distinguishes each unique inventor from all other inventor records in a patent database. This task is essential for processing person name queries in order to get information related to a specific inventor, e.g. a list of all that inventor's patents. Using earlier work on author name disambiguation, we apply it to inventor name disambiguation. A random forest classifier is trained to classify whether each pair of inventor records is the same person. The DBSCAN algorithm is use for inventor record clustering, and its distance function is derived using the random forest classifier. For scalability, blocking functions are used to reduce the complexity of record matching and enable parallelization since each block can be run simultaneously. Tested on the USPTO patent database, 12 million inventor records were disambiguated in 6.5 hours. Evaluation on the labeled datasets from USPTO PatentsView competition shows our algorithm outperforms all algorithms submitted to the competition.
