Text2ALM

  1. UNO
  2. NLPKR Lab
  3. Software
  4. Text2ALM

Text2ALM is an advanced information extraction tool turning implicit information in text into set of facts capturing key properties of entities mentioned in text. It relies on multiple linguistic and knowledge representation resources: Verbnet lexicon, Text2DRS tool, CoreNLP Stanford tool, LTH semantic role labeler, CoreALMLib knowledge library, CALM solver for knowledge representation language ALM.

To examplify Text2ALM at work consider a narrative:

John traveled to the garage.
John picked up a football.
John went to the kitchen.

The output of Text2ALM will be the following:

location(John, garage, 1), location(John, garage, 2), location(John, kitchen, 3),
held_by(football, John, 2), held_by(football, John, 3),
location(football, garage, 2), location(football, kitchen, 3)

The system is hosted on GitHub:

https://github.com/cdolson19/Text2ALM

This repository includes detailed documentation on how to setup this tool (and all relevant systems) on a LINUX system and includes a manual on how to use Text2ALM.

The following repository

https://github.com/amdorsey12/X_Text2ALMClientRelease

hosts a related project that enhances the experience with Text2ALM by supporting it with explanations provided by Xclingo system.

The systems are documented in the following publications:

  • Yuliya Lierler, Gang Ling, Craig Olson. "Information Extraction Tool TEXT2ALM: From Narratives to Action Language System Descriptions and Query Answering", technical report, 2022
  • Adrian Dorsey, "Extending ext2ALM with new information and explanations by Xclingo", master project technical report, 2021

  • Yuliya Lierler, PLW Tutorial: "Processing Narratives by Means of Action Languages​" (Presentation), Philadelphi Logic Week, 2019

The project has been inspired by the ideas discussed in:

Yuliya Lierler, Daniela Inclezan and Michael Gelfond. "Action Languages and Question Answering", Proceeding of the 12th International Conference on Computational Semantics, 2017
