A new type of deep contextualized word representation is introduced that models both complex characteristics of word use and how these uses vary across linguistic contexts, allowing downstream models to mix different types of semi-supervision signals. This work reformulates the problem of predicting the context in which a sentence appears as a classification problem, and proposes a simple and efficient framework for learning sentence representations from unlabelled data. A very interesting result of this work is that the word vectors In order to deliver relevant information in different languages, efficient A system for selecting sentences from an imaged document for presentation as part of a document summary is presented. a simple data-driven approach, where phrases are formed Natural Language Processing (NLP) systems commonly leverage bag-of-words co-occurrence techniques to capture semantic and syntactic word relationships. 31113119.
