Embedding & Knowledge graph: Semantic search at your service

I design and deploy semantic search based on embeddings and knowledge graphsWe're here to help you turn your data into strategic leverage.

Each project is designed to be modular, explainable and scalableto integrate seamlessly into your technical environments and meet your specific business needs.

Vector representation (Embeddings)

Transformation of your textual, visual or relational data into semantic vectors to enable :

  • Search by similarity of meaning (beyond keywords).
  • Improving recommendation systems.
  • Pipeline optimization for Retrieval-Augmented Generation (RAG).

Knowledge graph construction

Model your data as network of entities and relationships :

  • Definition of ontologies and business schemas.
  • Automatic entity and relationship extraction via NLP/LLM.
  • Storage and querying in graph-oriented databases (Neo4j, GraphDB, Amazon Neptune).

Hybrid and semantic search

Combination of vector embeddings and knowledge graphs as a gift :

  • More relevant, contextual search.
  • Answers that can be explained and traced.
  • Better use of your unstructured and structured data.

Frameworks and advanced technologies

Using the best tools on the market :

  • Hugging Face Transformers, PyTorch, TensorFlow for embeddings.
  • Neo4j, SPARQL, Cypher for knowledge graphs.
  • Elasticsearch and Qudrant for vector research.

This approach enables me to deliver reliable, comprehensible and production-ready semantic searcheswhile remaining aligned with your strategic objectives.
