Researchers have developed a new method called adaptive q-log odds to improve the performance of BM25, a popular search algorithm, specifically for code retrieval tasks. This technique modifies the underlying mathematical formula of BM25 to better distinguish between similar code functions by adjusting how it weighs unique identifiers. When tested on a dataset of Go code, the new method significantly boosted retrieval accuracy, increasing the normalized discounted cumulative gain (NDCG@10) by nearly 90%. The researchers also found that the effectiveness of this fix is dependent on the tokenization process and has minimal impact on general text retrieval. AI
IMPACT Enhances code search capabilities, potentially improving developer productivity and the accuracy of retrieval-augmented coding systems.
