LX Semantic Similarity is an online service for measuring the semantic similarity between words in Portuguese.

LX Semantic Similarity provides two types of search:

  • Calculating the semantic distance between a pair of words: By inserting two words, the service displays the distance between them and an interactive 2D plot (t-SNE embedding) with the 200 closest words to each of the input words.
  • Displaying the semantic cloud of a word: By inserting a single word, the service shows a word cloud with the 20 most similar words (using a larger font size for words closer to the input word) and a table with the 20 most similar terms (and their similarity with respect to the input word).

 

The model represents each word in its vocabulary by a vector of real numbers. This vector representation allows to obtain a measure of similarity between two or more words, calculated by means of the cosine distance between the vectors of those words.
