Overview of ARQMath 2020: CLEF Lab on Answer Retrieval for Questions on Math

摘要

The ARQMath Lab at CLEF considers rinding answers to new mathematical questions among posted answers on a community question answering site (Math Stack Exchange). Queries are question posts held out from the searched collection, each containing both text and at least one formula. This is a challenging task, as both math and text may be needed to find relevant answer posts. ARQMath also includes a formula retrieval sub-task: individual formulas from question posts are used to locate formulae in earlier question and answer posts, with relevance determined considering the context of the post from which a query formula is taken, and the posts in which retrieved formulae appear.
