TF-IDF Insights

What is TF-IDF?

TF-IDF (Term Frequency-Inverse Document Frequency) is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus. It is often used in information retrieval and text mining. The TF-IDF value increases proportionally to the number of times a word appears in the document and is offset by the number of documents in the corpus that contain the word, which helps to adjust for the fact that some words appear more frequently in general.

What other technologies are related to TF-IDF?

TF-IDF Competitor Technologies

Word2Vec

Word2Vec, like TF-IDF, is a method for vectorizing text documents, but it uses neural networks to learn word embeddings. It is a competitor because it offers an alternative approach to representing text for downstream tasks.

BERT

BERT (Bidirectional Encoder Representations from Transformers) is a more advanced technique for vectorizing text using transformers. It is a competitor because it offers contextualized word embeddings, often outperforming TF-IDF in many NLP tasks.
