29.07.2019 · Python | Positional Index. This article talks about building an inverted index for an information retrieval (IR) system. However, in a real-life IR system, we not only encounter single-word queries (such as “dog”, “computer”, or “alex”) but also phrasal queries (such as “winter is coming”, “new york”, or “where is kevin”).

Jul 21, 2021 · The positional embedding is a vector of same dimension as your input embedding, that is added onto each of your "word embeddings" to encode the positional information of words in a sentence (since it's no longer sequential). You could view it as a preprocessing step to incorporate positional information into your word vector representations.
