本文通过将科学文献中的数学表达式链接到其对应的维基百科文章中，解决了确定这些表达式的身份的挑战。数学表达式经常用来表示科学文献中的重要概念，但其中几个概念，例如著名的方程式，在文献中往往只有很少的解释。这项任务将允许我们从维基百科获得关于这些数学表达式的额外解释。本文提出了一种解决这一挑战的方法，即使用数学表达式的结构和周围文本来链接数学实体。我们的初步评估表明，需要数学结构和文本描述的平衡组合才能获得可靠的链接性能。
This paper addresses the challenge of determining the identity of math expressions in scientific documents by linking these expressions to their corresponding Wikipedia articles. Math expressions are frequently used to denote important concepts in scientific documents, yet several of them, for example, famous equations, often have minimal explanation in the documents. This task will allow us to obtain an additional explanation from Wikipedia regarding these math expressions. This paper proposes an approach to this challenge, where the structures and surrounding text of math expressions are used for math entity linking. Our initial evaluation shows that a balanced combination of math structures and textual descriptions is required to obtain reliable linking performance.
