# Pairwise cosine computation

### Description

Computes pairwise cosine similarities

### Usage

1 | ```
pairwise(x,y,tvectors=tvectors,breakdown=FALSE)
``` |

### Arguments

`x` |
a character vector |

`y` |
a character vector |

`tvectors` |
the semantic space in which the computation is to be done (a numeric matrix where every row is a word vector) |

`breakdown` |
if |

### Details

Computes pairwise cosine similarities for two vectors of words. These vectors need to have the same length.

### Value

A vector of the same length as `x`

and `y`

containing the pairwise cosine similarities. Returns `NA`

if at least one word in a pair is not found in the semantic space.
