Precision of EMBASE searching enhanced with new chemical name field

September  07, 2010 - 

 

A new Chemical Name Search field (/CNS) in EMBASE has been introduced to increase retrieval precision for chemical names. This new /CNS field operates across the entire EMBASE database to retrieve names indexed in the Chemical Name (/CN) and the CAS Registry Number (/RN) fields.

The /CNS field has SLART and proximity capabilities, and its chemical names are parsed on spaces and on non-alphabetic characters. For example, the chemical name 9-(3-Deoxy-D-ribofuranosyl)adenine is parsed as

  • 9
  • 3
  • Deoxy
  • D
  • ribofuranosyl
  • adenine

Dimethyl sulfone appears in the /RN field as dimethyl sulfone and can be retrieved in the /CNS field by searching the parsed entities

  • dimethyl
  • sulfone

Glyco flex iii appears in the /CN field and can be retrieved in the /CNS field by searching

  • glyco
  • flex
  • iii
