1. Dynamic Topic Models (2006 · 2,520 citations)
   Classic topic models such as LDA treat documents as exchangeable, so they cannot show how themes in an archive change over time.
2. A Statistical Approach to Machine Translation (1990 · 2,074 citations)
   The authors from IBM return to an old idea of Warren Weaver: machine translation can be done statistically rather than with hand-written rules.
3. Computation of the Probability of Initial Substring Generation by Stochastic Context-Free Grammars (1991 · 150 citations)
   Speech recognizers need a language model that predicts the next word from the words already heard. If that model is a stochastic context-free grammar (SCFG), the recognizer must know the probability that the grammar produces a sentence beginning with a given word sequence, not just the probability of a complete…
