Word2vec Guessing Game
Welcome to the guessing game assignment. Think of a target word and give "clue" words below that describe the target. The word2vec model will give the 10 words closest to the semantic mean of the given clues. See if you can make the computer guess your chosen target word.
Things the model can do for you
If you separate the words by a space, comma, or + sign, the model will take the vector sum of the semantic representations of the given words. Finally, the model will normalize the vector to be of length 1, essentially turning the sum vector into a mean vector. Examples:
- susi lemmikki
- susi, lemmikki
- susi + lemmikki
- susi + lemmikki + häntää + haukkua
By separating words with a - sign, the model will take the vector difference of the semantic representations of the given words. Taken by itself, this difference vector is not that informative. However, when combined with summation you can make the model start at the representation of a word and then make the model move in a certain direction. For example: “king - man” will compute the difference vector (i.e. the direction) from man to king and “king - man + woman” will add this difference vector to the semantic representation of “woman”. In essence, this will compute “a man is to a king as a woman is to a …?” Examples:
- kuningas - mies + nainen
- kuningatar - kuningas + mies
- Taiwan - China + Venäjä
- jalka - polvi + kyynärpää
