Computes cosines between a sentence/ document and multiple words
a character vector specifying a sentence/ document (or also a single word)
a character vector specifying multiple single words
the semantic space in which the computation is to be done (a numeric matrix where every row is a word vector)
The format of
y) can be of the kind
x <- "word1 word2 word3" , but also of the kind
x <- c("word1", "word2", "word3"). This allows for simple copy&paste-inserting of text, but also for using character vectors, e.g. the output of
Both x and y can also just consist of one single word. For computing the vector for the document/ sentence specified in
x, the simple Addition model is used (see
A numeric giving the cosine between the input sentences/documents
