Latest Patents

Cafarella's latest patents focus on open information extraction from the web. This innovative approach implements a new extraction paradigm that allows a system to make a single data-driven pass over a corpus of text. The system extracts a large set of relational tuples without requiring any human input. Utilizing training data, a Self-Supervised Learner employs a parser and heuristics to determine the criteria used by an extraction classifier for evaluating the trustworthiness of candidate tuples. The classifier retains tuples with a sufficiently high probability of being trustworthy. Additionally, a redundancy-based assessor assigns a probability to each retained tuple, indicating the likelihood that it represents an actual relationship between the objects involved. The retained tuples form an extraction graph that can be queried for information.
