Extracting temporal and causal relations based on event networks

作者:

Highlights:

• We propose an event network structure for extracting temporal and causal relations.

• By adopting open information extraction, we identify relation across multiple sentences.

• Our approach is able to identify temporal and causal relations in an unsupervised manner.

• Our work is able to identify both directly and indirectly observable relations.
