# ESO: The Event and Implied Situation Ontology.

This repository contains the Event and implied Situation Ontology (ESO). 
This is version 2.0 (stable), which was developed for [the NewsReader Project](http://www.newsreader-project.eu/).

## Resource Description
The Event and Implied Situation Ontology (ESO.owl), is a manually constructed resource which formalizes 
the pre-, during-, and post-situations of *events* and the *roles* of the entities affected by an event.

The ontology is used to detect information in large natural language document collections that otherwise would 
have remained implicit.

A *situation* is seen here as some abstract state where some properties and property values hold. 
If something happens in the world, there is a change in at least some of the values of these properties.
For instance: an event associated with the concept or class eso:Buying will have a two cognitive agents carrying the role of
owner-1 and owner-2, some object and some financial asset (usually money). ESO models and infers the following:

* Before the buying event: owner-1 has the object but not the money; owner-2 has the money but not the object.
* During the buying event: there is an exchange of object and money where the money expresses the value of the object.
* After the buying event: owner-1 has the money but not the object; owner-2 has the object but not the money.

### Prerequisites
ESO is fully mapped to [SUMO](http://www.adampease.org/OP/) on class level and to [FrameNet](https://framenet.icsi.berkeley.edu/fndrupal/) on class and role level. 
As an input, ESO needs Semantic Role Labeled annotation based on FrameNet. An additional vocabulary with manually created WordNet-FrameNet-ESO 
mappings is provided too.

If you have PropBank, VerbNet or SemLink annotated data, I refer to the [Predicate Matrix](http://adimen.si.ehu.es/web/PredicateMatrix), 
a resource developed by Maddalen Lopez de Lacalle, Egoitz Laparra and German Rigau, IXA Group, Basque University.

### Contents ESO

ESO is developed for the automotive and financial domain. It contains: 63 event classes; 123 situation rule assertions;
58 properties; 65 roles. Further, 46 SKOS mappings to SUMO classes; 103 SKOS mappings to FrameNet frames and 131 to Frame Elements (roles).

## Repository Description

* `ESO-2.owl` This is ESO version 2 (stable)
* `Documentation.pdf` This is the documentation of the ESO Ontology
* `ESO-HumanReadable.pdf` This file contains a transcription of ESO classes and provides examples of the instantiation of the assertions.
