Abstract: In this methodological note, the recall and precision of a mixed 
thematic filter developed for the delimitation of the Marine Science area 
by means of specialised journals and keywords is analysed, and its 
efficiency is compared with a delimitation based only on scientific 
journals. The scientific production of Marine Science in Spain during 1994-
2004 as covered by SCI, SSCI & AHCI is analysed. A high precision (96%) 
but a very low recall (close to 30%) is obtained by the delimitation 
strategy based only on scientific journals. The mixed filter presents a 
lower precision (69%) but a higher recall (around 75%). The journal-based 
delimitation provides an incomplete view of the area in which high-impact 
documents published in journals of other disciplines are ignored. The 
interest of developing advanced filters for the delimitation of scientific 
areas and the importance of expert opinions in order to obtain a balance 
between precision and recall are stressed.
