Claim 0:
1. A system for producing a causal map from a body of text describing observed events, the system comprising:
one or more processors and a non-transitory computer-readable medium having executable instructions encoded thereon such that when executed, the one or more processors perform operations of:
receiving a plurality of textual documents as input;
extracting pairs of cause-effect phrases from the plurality of textual documents;
embedding the cause-effect phrases into a vector space, resulting in embedded data;
clustering the embedded data into a plurality of clusters using a probabilistic technique;
generating a causal map, comprising a plurality of nodes and edges, from the plurality of clusters;
using the causal map, obtaining causal connections between clusters, wherein each node represents an event and each edge represents a causal relationship between events; and
providing the causal map as an interactive graph.
