Random-Walk-based Natural Language Processing Algorithm

A Random-Walk-based Natural Language Processing Algorithm is a NLP Algorithm that is based on a Random Walk Algorithm.

• AKA: Random Walk Natural Language Processing (RW-NLP) Algorithm.
• Example(s):
  • a Random-Walk-based Sense Disambiguation Algorithm (e.g.Pilehvar et al., 2013),
  • a Random-Walk-based Text Semantic Similarity Algorithm (e.g. Ramage et al., 2009),
  • …
• Counter-Example(s):
  • an Alignment-based Linguistic Sense Disambiguation Algorithm,
• See: Word Sense Disambiguation Algorithm, Align-Disambiguate-Walk (ADW) Semantic Similarity System, Random Walk Probabilistic Model, Semantic Word Similarity, Semantic Textual Similarity.

  • QUOTE: Given a particular node (sense) in the network, repeated random walks beginning at that node will produce a frequency distribution over the nodes in the graph visited during the walk. To extend beyond a single sense, the random walk may be initialized and restarted from a set of senses (seed nodes), rather than just one; this multi-seed walk produces a multinomial distribution over all the senses in WordNet with higher probability assigned to senses that are frequently visited from the seeds.
