WebOct 30, 2024 · Calculating String Similarity in Python. Comparing strings in any way, shape or form is not a trivial task. Unless they are exactly equal, then the comparison is easy. But most of the time that won’t be the case — most likely you want to see if given strings are similar to a degree, and that’s a whole another animal.
WebMay 29, 2024 · Introduction. Sentence similarity is one of the most explicit examples of how compelling a highly-dimensional spell can be. The thesis is this: Take a line of sentence, transform it into a vector.; Take various other penalties, and change them into vectors.; Spot sentences with the shortest distance (Euclidean) or tiniest angle (cosine similarity) … WebMar 28, 2024 · The key idea is that similar words have vectors in close proximity. Semantic search finds words or phrases by looking at the vector representation of the words and finding those that are close together in that multi-dimensional space. ...
