To illustrate, we wish to calculate the distance between the concepts of „MySQL” and<br />

„C++”. The closest common parent is „IT”, and thus the calculation is:<br />

dc(MySQL, C++) = dc(MySQL, IT) + dc(C++, IT)<br />

= (1/4-1/16) + (1/4-1/16) = 0,25<br />

Thus, the similarity between the two concepts is:<br />

simc(MySQL, C++) = 1 – 0,25 = 0,75<br />

The distance between two remote concepts would be:<br />

dc(Invoicing, OracleDatabase) = (1/2-1/16) + (1/2-1/16) = 0,875<br />

and their similarity:<br />

Finance<br />

simc(Invoicing, OracleDatabase) = 1-0,875 = 0,125<br />

Bizer et. (2005:11) al propose a scheme for integrating competence levels (cl)<br />
