COMMONSENSE
KNOWLEDGE GRAPHS

Marvin
Minsky
“To build a machine that
truly learns by itself will
require a commonsense
knowledge representing
the kinds of
things even a small child
already knows.”
“One problem is much of
our commonsense
knowledge information
has never been recorded
at all because it has
always seemed so
obvious we never
thought of describing it.”

Marvin Minsky
Minsky’s architecture of CK
representation

Marvin Minsky
Commonsense knowledge is
defeasible and context dependent.
Blanco, Cankaya and Moldovan
The fact that birds have feathers and
ice is cold seems trivially true. Yet
most machine-readable sources of
knowledge either lack such
commonsense facts entirely or have
limited cover age
Tandon, Melo and Weikum
There is a strong need for computers
having commonsense knowledge to
support the interpretation of user
input in search, dialogs, etc.. Digital
assistants like Amazon Echo, Microsoft
Cortana, Apple Siri or Google Now
would especially benefit from
knowledge about human activities.
Tandon, Melo, De and Weikum
Publicly available knowledge bases
(KBs) like DBpedia, Freebase,
Wikidata, and Yago and commercial
KBs at Google, Microsoft, Bloomberg,
etc. focus on facts about individual
entities, hardly containing any
commonsense knowledge at all.
Tandon, Melo, De and Weikum

Different Types of Graph Weights
FREQUENCY
RESISTANCEDISTANCE
FLOW

Source for the four types of graph
weights

Weight One - Frequency

There is frequency in ‘locationOf’
concept relations

...frequency in
‘spatialProximityWith’ relations

Transport as a concept that
frequently relates with bikes

NLTK and the Wordnet extension
to identify entity relations

SpaCy’s entity visualisation to
identity relations

Google’s NLP entity visualisation
to identity bike relations

Bike shorts and tricks are entities
that frequently occur with a bike

Weight Two - Flow

When ‘isA’ relations between
objects indicate flow

‘effectsOf’ relations highlight flow
between concepts

There is object flow in ‘requires’
relations

An object flow in ‘makesYou’ and
‘typeOf’ relations?

You’ve got object flow in
‘makersOf’ or metonymy relations!

What bicycle is ‘usedFor’ has flow
in relations

Some flow in ‘capableOf’ relations
for dads

Skiing flows with risk and
challenge

Weight Three - Distance

Distance is established in a
‘fasterThan’ relations

Distance in ‘muchSmallerThan’
relations

Riding a bike is distant from
obtaining a license

Weight Four - Resistance

Dogs resist fleas in a
‘doesn’tWant’ relations

More resist weight in
‘doesn’tWant’ relations

…elements of resistance in
‘capableOf’ relations

…chunks of resistance in
‘usedOf’ relations

Riding a bike resists
reading a book

WRAPPING IT ALL UP

CKGs can be used in your audience
strategy

Guides your keyword and content
strategy
...looking at entities that frequently exists alongside your main concept- both
words that flow and resists

CKG inspires deeper content
structures

Using wordnet ontology to inform
site architecture
Hypernym
Hyponym
Meronym
Class
Concept
Properties
Wheeled Vehicle
Bike
Bicycle Wheel

CKG enables culturally relevant ads
● Boxes of corned beef
are token of treasure
to Samoans
● Popular at main
events like weddings,
birthdays and funeral
● Also symbols of
appreciation
● Alternatives to the
extinct treasure of
fine mats
Corned Beef and Samoans

Movie scripts as great source
of CKG

Sequence of event scripts as great
source for CKG

Narrative journalism as rich source
for CKGs

Text from novels can enrich a CKGs

Semantic Scholar has great CKG
papers

A great PHD Thesis on
Commonsense Knowledge
