Action Network
ConcepNet (MIT Media Lab) [20] is a well known action network. This action net-
work is a semantic network of commonsense knowledge, based on the information in
OpenMind commonsense corpus (OMCS) [21].
Figure 11 shows comparisons of TiAN and ConcepNet. ConceptNet prepared a list of
patterns in advance, and then it uses these patterns to obtain concepts, and the relations
between these concepts. For example, given “A pen is made of plastic” as an input
sentence, it uses “NP is made of NP” to get two concepts (a pen, plastic), and the
relation (is made of) between these concepts. However, it is not practical to deploy
this method for extraction of human activities from Twitter, because sentences retrieved
from twitter are often diversified, complex, syntactically wrong. Additionally, TiAN is
standardized based on OWL. Moreover, TiAN is a dynamic collaborative intelligence
that represents instances of human activities in real-world.
