The BETTER program aims to dramatically compress the information discovery cycle by designing systems that extract personalized, semantic information from text and leverage this information to substantially improve search capabilities.

Background

The BETTER program created datasets for information extraction and cross-language information retrieval. These datasets were built using content from the CommonCrawl news collection. The linguistic annotations were provided by MITRE and ARLIS, and relevance assessment annotations by NIST. The datasets were structured around the following six evaluation tasks:

Abstract IE

Identify events in a sentence, and mark them as material or verbal, helpful or harmful.

Basic IE

Basic events have a type, an agent, a patient, and possibly related events. You might think of Basic as stripped-down MUC events.

Granular IE

Granular events are templates for events that consist of several component Basic events.

Automatic IR

Cross-language retrieval by example, fully automatic given a small number of example documents and passages in place of a query.

HITL IR

Retrieval with a human in the loop. The user is shown a small number of requests with narrative descriptions, and allowed to tune the system for future requests on the same topic.

Auto-HITL IR

"Automatic" HITL, where systems are shown the small number of requests with narrative descriptions, and automatically adapt the system to future requests, for example by creating background queries.

Abstract

Abstract events consist of agent, patient, event anchor, and quad-class. The quad-class is a two-dimensional event type that can be either Material and/or Verbal, and Helpful or Harmful.

As an example, consider the sentence below and the abstract events identified in the table below it. This sentence mentions four events that would be captured in the abstract extraction task.

“According to several witnesses, the boiler explosion in the factory injured three people, but did not melt any of the nearby fuel lines.”
Event ID Agent(s) Anchor(s) Patient(s) Quad-class
1 "several witnesses" "according" "injure", "melt" Verbal-Neutral
2 "boiler" "explosion" "boiler" Material-Harmful
3 "explosion" "injure" "three people" Material-Harmful
4 "explosion" "melt" "the nearby fuel lines" Material-Harmful
