Problem Statement: The goal of Part I of the task is to use raw textual data in language models for recommendation based application. The goal of Part II of task is to implement comprehensive preprocessing steps for a given dataset, enhancing the quality and relevance of the textual information. The preprocessed text is then transformed into a featurerich representation using a chosen vectorization method for further use in the application to perform similarity analysis. Part I Sentence completion using Ngram: Recommend the top words to complete the given sentence using Ngram language model. The goal is to demonstrate the relevance of recommended words based on the occurrence of Bigram within the corpus. Use all the instances in the dataset as a training corpus. Test Sentence: "how could Part I Perform the below sequential tasks on the given dataset. i Text Preprocessing: Tokenization Lowercasing Stop Words Removal Stemming Lemmatization ii Feature Extraction: Use the preprocessed data from previous step and implement the below vectorization methods to extract features. Word Embedding using TFIDF iii Similarity Analysis: Use the vectorized representation from previous step and implement a method to identify and print the names of top two similar documents that exhibit significant similarity. Justify your choice of similarity metric and feature design. Visualize a subset of vector embedding in D semantic space suitable for this use case. HINT: Use PCA for Dimensionality reduction
