    "title": "Quantifying the Conceptual Combination Effect on Word Meanings",
    "subtitle": null,
    "abstract": "How do people understand concepts such as dog, aggressive\ndog, dog house or house dog? The meaning of a concept\ndepends crucially on the concepts around it. While this\nhypothesis has existed for a long time, only recently it has\nbecome possible to test it based on neuroimaging and quantify\nit using computational modeling. In this paper, a neural\nnetwork is trained with backpropagation to map attribute-\nbased semantic representations to fMRI images of subjects\nreading everyday sentences. Backpropagation is then\nextended to the attributes, demonstrating how word meanings\nchange in different contexts. Across a large corpus of\nsentences, the new attributes are more similar to the attributes\nof other words in the sentence than they are to the original\nattributes, demonstrating that the meaning of the context is\ntransferred to a degree to each word in the sentence. Such\ndynamic conceptual combination effects could be included in\nnatural language processing systems to encode rich contextual\nembeddings to mirror human performance more accurately.",
