Numeric data identification and normalization

• Numbers and their units are identified within the

text and made fully numerically searchable

‒ 1,800 chemical and physical property unit variants are

identified, normalized and indexed

‒ Both exact values and ranges

• Identified original data are normalized to base units

and indexed for searching

‒ 55 numeric property search fields are available

4

Numeric property search fields and base units:

http://www.stn-international.com/pqscitech_nps.html




Numeric property data can be searched within all

English-language text fields

• Numeric search terms can be combined with text-

based search terms of interest

‒ Using standard text-based proximity operators

‒ Specifying text fields of interest, e.g. abstract (/AB)

• Flexible data input options are available

‒ Ranges, exact values and tolerances

‒ A wide variety of STN search units
