Identifying Similar Sentences by Using N-Grams of Characters

Nowadays, detecting similar sentences can play a major role in various fundamental applications for reading and analyzing sentences like information retrieval, categorization, detection of paraphrases, summarizing, translation etc. In this work, we present a novel method for the detection of similar sentences. This method highlights the using of units of n-grams of characters. The online dictionary as well as any search engine are not being used. Hence, this idea leads our method a simplest and optimum way to handle the similarities between two sentences. In addition, the grammar rules as well as any syntax have not been used in our method. That's why, our approach is language-independent. We analyze and compare a range of similarity measures with our methodology. Meanwhile, the complexity of our method is O(N2) which is pretty much better.
