Building on the success of representing individual words as vectors, the research focus in NLP expanded to learning representations for entire sequences of text. This progression was enabled by more powerful language models, such as those using LSTM architectures. The subsequent introduction of the Transformer model dramatically accelerated this trend, causing a surge in research and development of sequence representation techniques.

Shift from Word to Sequence Representations

Early natural language processing systems often represented the meaning of a sentence by simply averaging the numerical vectors of its individual words. Analyze the primary limitations of this approach. Then, explain the conceptual shift in how more advanced models began to represent entire sequences of text to overcome these limitations.

From Words to Sentences: A Paradigm Shift in Text Representation

Arrange the following approaches to text representation in the chronological order of their conceptual development, from focusing on individual words to capturing the meaning of entire sequences.

A language processing system analyzes product reviews by converting each word into a numerical vector that represents its individual meaning. To understand the overall sentiment of a review, the system simply calculates the average of all the word vectors. Which of the following reviews would this system most likely misinterpret, revealing a fundamental limitation of relying solely on individual word meanings?
