## What it is
A TensorFlow implementation of a deep siamese LSTM network that learns phrase and sentence similarity using character-level and word-level embeddings. It trains on pairs of texts with a contrastive loss to capture semantic and structural similarity.

## Use cases
- measure similarity between two sentences
- match person name variants and abbreviations
- detect duplicate or paraphrased phrases
- train a model to score semantic similarity of text pairs
- learn character-level embeddings for typo-tolerant string matching

## When to choose
- you need a reference implementation of siamese LSTMs for text similarity research
- you want to learn pair-based similarity with character or word embeddings on legacy TensorFlow 1.x

## When to avoid
- you need production-grade code - the author explicitly marks it as an experimental prototype
- you use modern TensorFlow 2.x or PyTorch - it targets TensorFlow 1.2
- you want a maintained library or pretrained sentence embedding model
