Comparison of methods to assess similarity between phrases
Renzo Angles, Valeria Araya, Jesus Concha and Rodrigo Paredes
We study the problem of similarity between phrases.
To do so, we study three similarity methods.
The first one considers the commonalities and differences of the
two phrases.
The second one is an extension of the well-known Levenshtein-Damerau
distance in a word oriented fashion.
The third one considers the sequentiality of the phrases
and is resistant to phrases with repeated words.
Finally, we show an experimental evaluation of our methods in both English
and Spanish corpora.
