Ollie is software that automatically identifies and extracts binary relationships from English sentences. Ollie is designed for information extraction, where the target relations cannot be specified in advance and speed is important.

To get a better idea of what Ollie does:


If you want to run Ollie on a small amount of text without modifying the source code, you can use an executable file that can be run from the command line. Follow these steps to get started:
  1. Download the latest Ollie binary.
  2. Download the linear English MaltParser model and place it in the same directory as Ollie.
  3. Run java -Xmx512m -jar ollie-app-latest.jar yourfile.txt. The input file should contain one sentence per line unless --split is specified. Omit the input file for an interactive console.


The Ollie source is available on GitHub.
