#bert #informationretrieval #nlp Query expansion ( QE) is the process of reformulating a given query to improve retrieval performance in information retrieval operations, particularly in the context of query understanding. This paper introduces BERT to find relevant chunks from the documents as possible augmentations to the given query. ✔️ Automatic Python code generation from Spreadsheet - Mito - https://bit.ly/3eo4Wwi ⏩ Abstract: Query expansion aims to mitigate the mismatch between the language used in a query and in a document. However, query expansion methods can suffer from introducing non-relevant information when expanding the query. To bridge this gap, inspired by recent advances in applying contextualized models like BERT to the document retrieval task, this paper proposes a novel query expansion model that leverages the strength of the BERT model to select relevant document chunks for expansion. In evaluation on the standard TREC Robust04 and GOV2 test collections, the proposed BERT-QE model significantly outperforms BERT-Large models.
