AutoSlog System

An AutoSlog System is an text-based information extraction algorithm that automatically built dictionaries based on slot-filling rules in a manner that is similar to the one proposed in (Riloff, 1993).

• Context:
  • It was trained on an Annotated Corpus.
  • It used simple linguistic Rules.
• See: Extraction-Rule Learning.

• TBD
  • Used a corpus of answer keys and texts from MUC-4 to compare filled templates with the sentences they were taken from.
  • Compared a sentence's linguistic parse to a set of heuristic linguistic patterns
  • Built a syntactic pattern to extract noun phrases similar to the slotfillers from the template.
  • Given the slot-filler "bombed", for example, Auto-Slog might find a sentence with the phrase "public buildings were bombed" and associate the pattern <subject> passive-verb with it, extracting "public buildings" as a dictionary term.
