ReTraCk is designed as a modular framework to achieve high flexibility and efficiency. The system includes a retriever to access relevant KB items efficiently, a transducer to generate logical form with syntax correctness guarantees, and a checker to improve the transduction procedure.<\/p>\n<p>ReTraCk is ranked at top1 overall performance on the <a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" href=\"https:\/\/dki-lab.github.io\/GrailQA\/\">GrailQA leaderboard<\/a> (as of Apr\/2021) and obtains highly competitive performance on the classic <a href=\"https:\/\/www.microsoft.com\/en-us\/download\/details.aspx?id=52763\">WebQuestions Semantic Parse<\/a> benchmark.
