Drawing on ideas from cognitive linguistics, connectionism, and perception, The HumanSemantic Potential describes a connectionist model that learns perceptually grounded semantics fornatural language in spatial terms. Languages differ in the ways in which they structure space, andRegier's aim is to have the model perform its learning task for terms from any natural language. Thesystem has so far succeeded in learning spatial terms from English, German, Russian, Japanese, andMixtec.The model views simple movies of two-dimensional objects moving relative to one another andlearns to classify them linguistically in accordance with the spatial system of some naturallanguage. The overall goal is to determine which sorts of spatial configurations and events arelearnable as the semantics for spatial terms and which are not. Ultimately, the model and itstheoretical underpinnings are a step in the direction of articulating biologically based constraintson the nature of human semantic systems.Along the way Regier takes up such substantial issues as theattraction and the liabilities of PDP and structured connectionist modeling, the problem of learningwithout direct negative evidence, and the area of linguistic universals, which is addressed in themodel itself. Trained on spatial terms from different languages, the model permits observationsabout the possible bases of linguistic universals and interlanguage variation.Neural NetworkModeling and Connectionism series
