摘要: The unique structural syntax and the variety of semantic equivalences mathematic expressions make it a challenge for keyword-based text search engine to effectively meet users’ needs. Many existing math solutions focus on exact where notational matching determines relevance rank, while similarity mathematical semantics are often missed out or not addressed adequately. One important research question is how efficiently find that similar user’s query, do ranking hits by similarity. This paper focuses (1) conceptualizing between expressions, (2) defining metrics measure similarity, (3) utilizing those search, (4) evaluating performance validate advantage proposed search. Our results show math-similarity superior
