Bag-of-words representations are used in many NLP applications, such as text classification and sentiment analysis. These representations ignore relations across different sentences in a text and disregard the underlying structure of documents. While more linguistically elaborate models of text structure have been studied for decades, they are rarely used in text analysis applications. A reliance on handcrafted rules combined with the limited portability and scalability of these models makes bag-of-words approaches the representation of choice in practical settings. |
