Modules

lambda

The module that defines the basic lambda calculus used to compose expressions in the langauge of thought.

language

Defines the core language of thought of the model and a simple virtual machine.

Structs

DatasetError

Error for creating a dataset without equal sentences and scenarios.

PossibleEvent

A description of a possible kind of event (e.g. kind of verb)

Scenario

The representation of a scenario. A moment consisting of various events, the present actors and any predicates that apply to either.

ScenarioDataset

A struct defining a dataset of different Scenarios as well as their associated sentences all lemmas in the dataset.

ScenarioIterator

Generates all scenarios that can be generated with a given set of primitives

ScenarioParsingError

An error that arises from parsing a Scenario or ScenarioDataset

ThetaRoles

The representation of the theta roles of a given event.

Enums

Entity

The union of Actor and Event

EventType

The kinds of possible events

Type Aliases

Actor

The representation of an entity that can receive theta roles (e.g. a human, a cup, a thought).

Event

The representation of an entity that can assign theta roles (e.g. a runnning even, when its raining, etc.) They are representated as indices to the relevant ThetaRoles in a given Scenario.
