Distributional semantics has had enormous empirical success in Computational Linguistics and Cognitive Science in modeling various semantic phenomena,  Abstract. This paper investigates the role of Distributional Semantic. Models ( DSMs) into a Question Answering (QA) system. Our purpose is to exploit DSMs for  The focus of this course is on “distributional” approaches to semantics, i.e.

Since semantically similar words Deep Learning with the Distributional Similarity Model makes it feasible for machines to do the same in the field of Natural Language Processing (NLP). The famous quote by J.R.Firth sums up this concept pretty elegantly, “You shall know a word by the company it keeps!” Composition models for distributional semantics extend the vector spaces by learning how to create representations for complex words (e.g. ‘apple tree’) and phrases (e.g. ‘black car’) from the representations of individual words. The course will cover several approaches for creating and composing distributional word representations.

To show why the integration is desirable, and, more generally speaking, what we mean by general understanding, let us consider the following Distributional semantics provides multidimensional, graded, empirically induced word representations that successfully capture many aspects of meaning in natural languages, as shown by a large body of research in computational linguistics; yet, its impact in theoretical linguistics has so far been limited. Distributional semantic models (DSM) – also known as “word space” or “distributional similarity” models – are based on the assumption that the meaning of a word can (at least to a certain extent) be inferred from its usage, i.e. its distribution in text.

The two frameworks are complementary in their strengths, and this has motivated interest in combining them into an overarching semantic framework: a “Formal Distributional Semantics.” Subject: Computer ScienceCourses: Natural Language Processing Assignment: Distributional semantics.
