Use something along the line of the ingredient de-duplicating pipeline demonstrated in a neo4j tutorial using the BBC goodfood ingredients

Pipeline

  • download the goodfood dataset (scraping required !) - or something equivalend
  • normal NLP preprocessing steps
    • character encodings
    • tokenization
    • stemming (plurals)
    • stopwords / length etc.
  • connect tokens to an ingredient
    • ingredient: cherry tomato => parts: cherry and tomato
  • Use string distance to create similarity edges
    • sorensenDiceSimilarity ??
  • Use phonetic similarity to create similarity edges
    • doubleMetaphone ??
  • Run a community detection algorithm (like Louvain) to cluster similar ingredients together
