Measuring Word Significance using Distributed Representations of Words. Essentially, the weight of each word in the vector is distributed across many dimensions. So, instead of a one-to-one mapping between a word and a basic vector (dimension), the word contribution is spread across all of the dimensions of the vector. The dimensions are believed to capture the semantic properties of the words. The similarity between word vectors is defined as the square root of the average inner product of the vector elements (sqrt(sum(x . We introduce BilBOWA (Bilingual Bag-of-Words without Alignments), a simple and computationally-efficient model for learning bilingual distributed representations of words which can scale to large monolingual datasets and does not require word-aligned parallel training data.
