Predictive Top-Down Parsing for Hyperedge Replacement Grammars
2015Graph languages defined by hyperedge replacement grammars can be NP-complete. We invent predictive top-down (PTD) parsers for a subclass of these grammars, similar to recursive descent parsers for string languages. The focus of this paper lies on the grammar analysis that computes neighbor edges of nonterminals, in analogy to the first and follow ...

Coarse classification using a hierarchical decision tree and top down parsing
ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005In this paper, we describe a robust technique for segmenting an utterance into a sequence of coarse phonetic classes. The resulting coarse class string is used to provide contextual information for further phonetic analysis, and in lexical access to limit the number of word candidates.

Memory Resource Allocation in Top-Down Minimalist Parsing
2013This paper provides a linking theory between the minimalist grammar formalism and off-line behavioural data. We examine the transient stack states of a top-down parser for Minimalist Grammars as it analyzes embedded sentences in English, Dutch and German.

Top-Down Online Handwritten Mathematical Expression Parsing with Graph Grammar
2015In recognition of online handwritten mathematical expressions, symbol segmentation and classification and recognition of relations among symbols is managed through a parsing technique. Most parsing techniques follow a bottom-up approach and adapt grammars typically used to parse strings.

Top-Down Parsing Error Correction Applied to Part of Speech Tagging
2020Natural Language Processing (NLP) applications are growing in popularity and importance, all of these applications rely upon the basic steps of tokenization, stemming and Part-of-Speech tagging (POS), and while those steps already work really well on English texts, the same cannot be said for every language.

A Top-Down Model for Character-Level Chinese Dependency Parsing
2019This paper proposes a novel transition-based algorithm for character-level Chinese dependency parsing that straightforwardly models the dependency tree in a top-down manner. Based on the stack-pointer parser, we joint Chinese word segmentation, part-of-speech tagging, and dependency parsing in a new way.
