APPENDIX 7: VALIDATION EXERCICE ON 35<br />
HARMONIZED NAMES<br />
A detailed validation exercise was conducted for 35 harmonized names to check for accuracy<br />
and completeness: 10 harmonized names that were matched to 1 original patentee name, 5<br />
harmonized names matched to 2 original patentee names, 10 names matched to 3 to 9 original<br />
patentee names, and 10 harmonized names matched with 10 or more original patentee names.<br />
Table 35 contains the results of the validation. The second column contains the num<strong>be</strong>r of<br />
original patentee names automatically identified by the name cleaning and harmonization<br />
method. The third column contains the num<strong>be</strong>r of patents assigned to these original patentee<br />
names. The fourth and the fifth column contain the num<strong>be</strong>r of original patentee names and<br />
assigned num<strong>be</strong>r of patents after validation respectively. The one but last column contains the<br />
num<strong>be</strong>r of patents assigned to the manually found additional name variations. The last column<br />
contains the difference in num<strong>be</strong>r of patents compared to the total num<strong>be</strong>r patents assigned to<br />
all manually identified name variations (cases in bold indicate completeness <strong>be</strong>low 97%) 16 .<br />
