Automatic Knowledge Base Construction using Probabilistic Extraction, Deductive Reasoning, and Human Feedback

We envision an automatic knowledge base construction system consisting of three interrelated components. MADDEN is a knowledge extraction system applying statistical text analysis methods over database systems (DBMS) and massive parallel processing (MPP) frameworks; PROBKB performs probabilistic reasoning over the extracted knowledge to derive additional facts not existing in the original text corpus; CAMEL leverages human intelligence to reduce the uncertainty resulting from both the information extraction and probabilistic reasoning processes.
