Solution

Word embeddings are a type of word representation that allows words with similar meaning to have a similar representation. They are a distributed representation for text that is perhaps one of the key breakthroughs for the impressive performance of deep learning methods on challenging natural language processing problems.

  1. Syntagmatic association or first-order co-occurrence: This refers to the relationship between words that often appear together in a specific order. For example, in the sentence "I drink coffee in the morning", "drink" and "coffee" have a syntagmatic relationship because they frequently appear together in this order. In word embeddings, words with a high syntagmatic association will be located close to each other in the vector space.

  2. Paradigmatic association or second-order co-occurrence: This refers to the relationship between words that can be substituted for each other in a particular context without changing the meaning of the sentence. For example, in the sentence "I drink coffee in the morning", "coffee" and "tea" have a paradigmatic relationship because you can substitute "tea" for "coffee" without changing the overall meaning of the sentence. In word embeddings, words with a high paradigmatic association will also be located close to each other in the vector space.

  3. The parallelogram model of relational similarity: This model is used to illustrate how word embeddings can capture both similarity and analogy relationships between words. In this model, word vectors are represented as points in a multi-dimensional space. The relationship between two words can be represented as the vector connecting their two points. For example, the vector from "king" to "queen" might represent the concept of "gender". If you add this "gender" vector to the point for "man", you should end up near the point for "woman". This demonstrates how word embeddings can capture analogy relationships (i.e., "man is to woman as king is to queen").
