Skip Gram Model Python Implementation for Word Embeddings

In this project, we worked with the Skip-Gram model, widely used for creating vector representations in NLP. The word embedding in this case refers to the process of transforming words into numbers that can be processed by the computer efficiently. This way the model can show how words are connected semantically and contextually. Consequently, this model type is helpful for, for instance, search engines, recommendations, and text categorization.

Project Description

This project aims to understand the Skip-Gram model and explores how it can be employed to produce meaning and relationships of words in numerical values called word embeddings. The procedure begins by cleaning and preprocessing the given input text to get rid of any irrelevant data and the data is ready for analysis. We then proceed to build a vocabulary that is geared towards training a neural net whereby the model attempts to guess the context words given a center word.

The model then saves the embeddings generated for some future use and their effectiveness is assessed by looking for analogous terms and measuring the distances of word pairs. For this purpose, we employed t-SNE, which is a dimensionality reduction technique with a particular focus on two- dimensional spaces to facilitate the perception of such embeddings. This suggests that such visual representation helps us understand how closely the words that are related are located to each other.

The interest contains the focus on nearly practical tasks, for instance, searching for keywords to find appropriate ones or dealing with datasets by using word topology. This also combines the technological advancements of machine learning and the enhanced techniques in illustrations, thus providing an understanding of how words are related in a text, which makes it useful for many NLP activities.
