LaTeX Formula Retrieval Method Based On Context Feature

The semantic recognition of the formula is an important factor in the formula retrieval results,and the accuracy of the retrieval system is directly affected by the correct identification of the ambiguous formula.The determination of the specific meaning of the ambiguity formula will help to provide more accurate results for users.In the formula retrieval,in order to provide the semantic information retrieval results consistent with user requirements and improve the accuracy of retrieval,the latex formula needs to be retrieved according to the characteristics of context.According to the ambiguity formula in retrieval process,a retrieval method combined with context characteristics is proposed.First,according to the location of the formula in the document,we determine the scope of the text description and process word segmentation of the formula context description,and then mark the context content of the extracted description formula into the data set.Finally,we match the data list and insert into the search results sequence according to the matching degree.The experimental results show that the method can effectively solve the semantic recognition of the ambiguous formula in the form of latex.
