Vector_Similarity

  • Python, Java implementation of TS-SS called from "A Hybrid Geometric Approach for Measuring Similarity Level Among Documents and Document Clustering"
  • Also, I have summarized "A Hybrid Geometric Approach for Measuring Similarity Level Among Documents and Document Clustering"
  • I recommend TS-SS instead of Cosine distance or Euclidean distance.

The reasons are...

Cosine drawbacks

coise_drawback

Euclidean drawbacks

euclidean drawback

Triangle's Area Similarity (TS)

TS

Sector's Area Similarity (SS)

Conclusion

  • In biggest dataset, TS-SS outperforms Cosine with a significant difference, while in other datasets TS-SS outperforms Cosine slightly

  • Therefore, the significant better result of TS-SS in biggest dataset justifies the robustness and reliability of the model for big data and real world data where the variety of documents/texts are high
