“…Previously analyzed methods for mapping queries face a trade-off between accuracy and execution time. The most accurate method uses an inverted index approach based on a BM25 retrieval model; however, its average time per query is much slower than a Trie data structure implementation, which is the fastest method [17]. To address this trade-off, we utilize the Neighborhood Graph and Tree (NGT) approximate nearest neighbor method [9], along with S anд and multilingual query vectors.…”

“…Three datasets have been proposed to evaluate the mapping of new incoming queries: the AOL query log (AOLQL), the TREC query topics (TRECQT), and the WikiHow questions (WIKIHQ) based datasets [17]. For comparison, we use publicly available implementations for the Trie data structure 1 and the BM25 retrieval model 2 with default parameters [17,19]. Experiments run on a virtual machine instance with 8 CPUs of 3GHz and 60GB of RAM.…”
