HIERARCHICAL ASSOCIATIONS
Skills terms and skills categories
are hierarchically associated
(similar to states under countries
and cities under states).
Hierarchical associations give
a good understanding when
drilled down from higher to
lower level
Machine Learning Algorithm Bayesian Algorithms Naïve Bayes
The hierarchical
levels range from 3 to

Skills terms and skills

associated (Roger is friend of

useful in creating holistic
skills profile

PROXY TERMS
Under Playing Musical Instrument
category we may have Guitar and Drums.
But the proxy terms used in search for
these are Playing Guitar and Playing Drums
and not just Guitar or Drums
Skills space is unique in the sense
the way a skill is written maybe
different from the way it is used in
conversations (or searched in a
database). Skills are assigned
proxies to enable proper meaning to
the skill in search

CONTEXTUAL REFERENCES
True sense of skills come from their contextual reference. Same
word can refer to different skill based on the context often derived
from use of a preceding or following word or term

Driving cars, Designing cars, Repairing cars are different skills derived
around cars derived from the prefixes used with cars
