A small experiment with Markov chains and species names

Markov species

A quick experiment with Markov chains, where a dictionary of n-grams is built from a list of latin species names. Using a simple Markov model, new species names are then generated. This utility is content-independant, and can be used to generate any kind of sequence of words from a dictionary.

Utilisation

• build dictionaries from a .csv list of words/sequences of words. --size denotes the maximum size of the n-grams to extract. A separate file will be generated for each n-gram size.

    markov_species build --size=3 path/to/file
  

  Log:

    Generating dictionnary with ngrams of size 2...
    Operation success: true. Dictionnary saved at path Markov Species/export_species_2.txt
    Generating dictionnary with ngrams of size 3...
    Operation success: true. Dictionnary saved at path Markov Species/export_species_3.txt
  

• generate species and print them to the standard output. --species denotes the number of sequences to generate, --words the number of words in each sequence, and --seed the RNG seed (uses rand48 under the hood).

    markov_species generate --species=5 --words=2 --seed=1234 path/to/dictionary
  

  Log:

    Generating 5 species names with a length of 2 words.
    Detected ngrams of length 3.
    Seed: 1234
