![]() ![]() Next, we describe two constraint-based methods that can be used to improve the recall of a shallow discourse parser based on conditional random field chunking. The three system versions are compared to evaluate their robustness with respect to deep/shallow and automatically extracted syntactic features. We train and evaluate three different parsers using the PDTB corpus. The parsing architecture is based on a cascade of decisions supported by Conditional Random Fields (CRF). ![]() We present a novel end-to-end discourse parser that, given a plain text document in input, identifies the discourse relations in the text, assigns them a semantic label and detects discourse arguments spans. ![]() We also compare the results of cascaded pipeline with a non-cascaded structured prediction setting that shows us definitely the cascaded structured prediction is a better performing method for discourse parsing. The comparative error analysis investigates the performance variability over connective types and argument positions. We show that the best combination of features includes syntactic and semantic features. We train the CRFs on lexical, syntactic and semantic features extracted from the Penn Discourse Treebank and evaluate feature combinations on the commonly used test split. We design the argument segmentation task as a cascade of decisions based on conditional random fields (CRFs). In contrast to previous work we do not make any assumptions on the span of arguments and consider parsing as a token-level sequence labeling task. In this research work first we take a data driven approach to identify arguments of explicit discourse connectives.

John Horgan, Scientific American, 14 Feb. 2021 The Times focuses on the enduring influence of the Game of Life, a cellular automaton invented by Conway more than a half century ago. Jean-paul Delahaye, Scientific American, 28 Apr. Matt Gardner, Forbes, Conway’s inclinations and talent led him to invent a remarkable cellular automaton called the Game of Life, which continues to fascinate after 50 years. John Horgan, Scientific American, 16 June 2021 Upgrade points unlock fighting combos and improve your automaton. Alex Jung, Vulture, 7 July 2021 Like the incompleteness theorem of Gödel, and like the Game of Life, a cellular automaton invented by mathematician John Conway, Penrose tiles suggest that even a universe based on simple rules can generate infinite, unpredictable complexity. 2021 Blitz, a Parisian automaton from 1850 and a family heirloom. Journe x Francis Ford Coppola, FFC Blue, a wristwatch that tells time via an automaton in the shape of a blue hand. 2021 This year’s most striking example is the F.P. The Physics Arxiv Blog, Discover Magazine, 31 Mar. 2022 In the late 1960s, the English mathematician John Conway began experimenting with a strange form of computer known as a cellular automaton. Todd Plummer, Condé Nast Traveler, 7 Sep. Recent Examples on the Web The hotel's resident automaton, MOBI, greets guests, escorts them to their rooms, and even delivers small amenities from a stowage compartment in its belly, providing service with a (digital) smile.
