Detailed Description

One step markov chain translation model, not fully tested yet.

This code is included mainly to illustrate how the toolkit can be used for estimating such models.

Constructor & Destructor Documentation

OneStepMarkovChain::OneStepMarkovChain ( WeightedIDSet & docSet, Index & homeIndex, double * wdNorm, double stopProb )

construct a MC restricted to a subset of docs.

OneStepMarkovChain::~OneStepMarkovChain ( )

Member Function Documentation

bool OneStepMarkovChain::hasMoreFromWord ( ) [inline]

void OneStepMarkovChain::nextFromWordProb ( int & fromWord, double & prob )

Fetch the next word and the prob of "translating" it to the toWord.

void OneStepMarkovChain::startFromWordIteration ( int toWord )

Start iteration over w's for t(toWord |w). Given a word, this provides a way to access the translation probability from any word to this word. E.g., given w, each iteration would give us t(w|w1), t(w|w2), ..., t(w|w_n).
