How does the Desklib algorithm for text similarity work?

Our algorithm provides users to search via strict sequence matching as well as find similar sentences in two texts. We provide the following options for comparison:

  • Strict Sequence Matching: This will find common sequences occurring in two texts. This is useful in case of finding edits between two documents, codes, transcripts, etc.
  • Sequence Matching of important words: This will find sequences excluding general words (e.g., a, an, the, is, etc.) focusing on relevant words. This is useful for sequence matching of relevant keywords avoiding generic matches with common words.
  • Sentence comparison: This will compare texts and provide similar sentences in two texts. It is useful for comparing two documents to identify paraphrasing and finding sentences with similar meanings.
