remworks.markov-chain — markov-chain 0.2.0

Implementation of Markov Chain to generate, for instance, text.

analyse clj/s

(analyse corpus & {:keys [lookback max-length] :or {lookback 2}})

Analyse corpus and return a state space. Option lookback determines the strength of the lookup key and defaults to 2. max-length will be set to largest row length in the corpus if no value is supplied.

analyse-text clj/s

(analyse-text text & opts)

Analyse text as a corpus of lines and words.

generate clj/s

(generate {:keys [space lookback max-length] :as state-space})

Generate new chains from given state-space. When the generated chain exceeds max-length it will contain ::et-cetera it the last position. This function uses weighted to do its random picking.

generate-text clj/s

(generate-text state-space)

Generate a new sentence from are state-space.

split-sentences clj/s

(split-sentences text)

Split text into sentences.

split-words clj/s

(split-words sentence)

Split sentence into words.

weighted clj/s

(weighted m)

Pick a random value from a weighted set given a map for values and weights. The CLJ implementation of this function uses clojure.data.generators, to get reproducible results use it's *rnd* binding .
