Three Generative, Lexicalised Models for Statistical Parsing
In this paper we first propose a new statistical parsing model, which is a generative model of lexicalised context-free grammar. We then extend the model to include a probabilistic treatment of both subcategorisation and wh-movement.

ABSTRACT Sentiment analysis, crucial for discerning emotional tones in text, relies on manual annotation to train machine learning models and is considered the gold standard for creating annotated corpora. However, this process is time‐consuming, labour‐intensive, and prone to biases. This paper proposes an automatic annotation approach for the Twitter‐

A Minimal Span-Based Neural Constituency Parser
In this work, we present a minimal neural model for constituency parsing based on independent scoring of labels and spans. We show that this model is not only compatible with classical dynamic programming techniques, but also admits a novel greedy top ...

We examined climate‐mediated portfolio effects within a population of the coastal dune endemic plant Cirsium pitcheri. We found that vital rates responded in opposite directions to climatic drivers, especially precipitation, in our five subpopulations that spanned the foredune to backdune.

Preparing, restructuring, and augmenting a French treebank: lexicalised parsers or coherent treebanks? [PDF]
We present the Modified French Treebank (MFT), a completely revamped French Treebank, derived from the Paris 7 Treebank (P7T), which is cleaner, more coherent, has several transformed structures, and introduces new linguistic analyses.

On LR(k)-Parsers of Polynomial Size [PDF]
Usually, a parser for an $LR(k)$-grammar $G$ is a deterministic pushdown transducer which produces backwards the unique rightmost derivation for a given input string $x \in L(G)$. The best known upper bound for the size of such a parser is $O(2^{|G|| |^k+k\log | | + \log |G|})$ where $|G|$ and $| |$ are the sizes of the grammar $G$ and the terminal ...

ABSTRACT Objective The association between eating disorders (EDs) and both trauma exposure and posttraumatic stress disorder (PTSD) is well established. Existing evidence is inconclusive about the impact of trauma exposure and/or comorbid PTSD on ED treatment outcomes and if comorbid ED affects PTSD treatment outcomes.

Construction Methods of LR Parsers [PDF]
This paper presents five different LR parser generators and an error recovery method which is derived directly from the LR parser. The parsers presented include the original LR (1) parser defined by Knuth.

Summary of the methodology and sequential steps conducted during the review. ABSTRACT The success of social media platforms has facilitated the emergence of various forms of online abuse within digital communities. This abuse manifests in multiple ways, including hate speech, cyberbullying, emotional abuse, grooming, and shame sexting or sextortion. In

Measuring Substitution Patterns in the Attention Economy: An Experimental Approach
ABSTRACT Substitution patterns are a crucial input to antitrust analysis, but measuring them for free digital products has proved difficult due to the lack of price variation. I measure substitution patterns by installing software on experimental participants' Android phones that restricts access to Instagram or YouTube—generating variation in choice ...
