| There is an increasing focus on Math Search. Meanwhile, with the enhancement of computer storage on mathematical Content, as well as the deepening support of browsers in the form of mathematics, it is feasible to carry out the research on the search engine about mathematical formula.Search for mathematical formula with traditional Search engine is insufficient because most of formulas have two-dimensional structure and complex meaning. Now, few studies have been concerned with the ranking algorithm for math search.Therefore, this paper will deal with the study of ranking algorithm for math search based on the study of text search engine ranking algorithm and combined with the relationship between mathematical formulas (equivalence, algebra relevance subformula).This paper combine the Computer algebra system(CAS) into search engine for mathematical to identify the relationship between formulas in order to make the ranking more reasonable and improve the intelligence of mathematical formula retrieval system and also promote the ability of semantic retrieval system on mathematical expressions. |
