    "title": "An Instance Theory of Distrobutional Semantics",
    "subtitle": null,
    "abstract": "Abstraction to a single prototypical representation is a core\nprinciple of Distributional Semantic Models (DSMs) that\nlearn semantic representations for words by applying\ndimension reduction to statistical redundancies in language.\nWhile the learning mechanisms for semantic abstraction vary\nwidely across the many DSMs in the literature, they are\nessentially all prototype models in that they create a single\nabstract representation for a word’s meaning. The prototype\nmethod stands in stark contrast to work in the field of\ncategorization that has converged on the importance of\ninstance models. In comparison to the prototype method,\ninstance-based models assume only an episodic store and,\nrather than applying abstraction mechanisms at learning,\nargue that meaning emerges in the act of retrieval. We cash\nthis idea out by presenting and evaluating an instance theory\nof distributional semantics, and by demonstrating that it can\nexplain diverging patterns of homonymous words that classic\n“abstraction-at-learning” models simply cannot as a\nconsequence of their architectural assumptions.",
