It is useful in determining just how similar two datasets are. However, you can easily convert a data frame to a matrix in R by using the as.matrix() function.ģ. Refer to this Wikipedia page to learn more details about Cosine Similarity. Cosine Similarity is a measure of the similarity between two non-zero vectors of an inner product space. findintroconchtml: To find the introduction and conclusion from the abstracts. Findconclusion: To find the conclusion from the abstract(s). cossimcalcboot: Cosine Similarity Calculation by Boot Strapping currentabsfn: To Retrive the Abstracts for year. The cosine() function will work on a matrix, but not on a data frame. cossimcalc: To calculate the cosine similarity between terms.
