English abstract

Patents include citations, both to other patents and to documents that are not patents (NPL, Non-patent literature). Non-patent literature (NPL) includes articles published in scientific journals. The technological impact of scientific works can be studied through the citations they receive from patents, just like the scientific impact of articles can be analyzed through the citations. The NPL references included in patents are far from being standardized, so determining which scientific article they refer to is not a trivial task. This paper presents a procedure for linking the NPL references of the patents collected in the Patstat database and the scientific works indexed in the Scopus bibliographic database. This procedure consists of two phases: a broad generation of candidate couples and another phase of validation of couples, and it has been implemented with reasonably good results at a low cost.

Spanish abstract

Las patentes incluyen citas, tanto a otras patentes como a documentos que no son patentes (NPL, Non-patent literature). Entre estas últimas se incluyen citas a artículos publicados en revistas científicas. Igual que se estudia el impacto científico a través la citación de artículos y otros trabajos científicos, también se puede estudiar el impacto tecnológico de los trabajos científicos a través de la citación que reciben de las patentes. Las referencias NPL incluidas en las patentes están lejos de estar normalizadas, por lo que determinar a qué artículo científico se refieren no es trivial. En este trabajo se presenta un procedimiento de enlazado de las referencias NPL de las patentes recogidas en la base de datos Patstat y los trabajos científicos indexados en la base de datos bibliográfica Scopus. Dicho procedimiento se compone de dos fases: una generación amplia de parejas candidatas y otra fase de validación de las parejas. Ha sido implementado con resultados razonables y costes asumibles.
