Information Representation Fairness in Long-Document Embeddings: The Peculiar Interaction of Positional and Language Bias
Elias Schuhmacher, Andrianos Michail, Juri Opitz +2
To be discoverable in an embedding-based search process, each part of a document should be reflected in its embedding representation. To quantify any potential reflection biases, w…
