Prior work has shown the utility of syntactic tree fragments as features in judging the grammaticality of text. To date such fragments have been extracted from derivations of Bayesianinduced Tree Substitution Grammars (TSGs). Evaluating on discriminative coarse and fine grammaticality classification tasks, we show that a simple, deterministic, count-based approach to fragment identification per...

The paper presents a novel sentence trimmer in Japanese, which combines a non-statistical yet generic tree generation model and Conditional Random Fields (CRFs), to address improving the grammaticality of compression while retaining its relevance. Experiments found that the present approach outperforms in grammaticality and in relevance a dependency-centric approach (Oguro et al., 2000; Morooka...

This papers deals with grammaticality judgments and their use as evidence in linguistic theory. Based on a review of the recent literature on linguistic judgments and their elicitation, the theoretical significance of judgment data is discussed, and an overview of the relevant experimental findings is provided. A number of linguistic and non-linguistics factors that bias grammaticality judgment...

Machine-produced text often lacks grammaticality and fluency. This paper studies grammaticality improvement using a syntax-based algorithm based on CCG. The goal of the search problem is to find an optimal parse tree among all that can be constructed through selection and ordering of the input words. The search problem, which is significantly harder than parsing, is solved by guided learning fo...

This paper discusses a number of implications of using either a conceptual approach or a lexico-semantic approach to terminology structuring, especially for interpreting data supplied by corpora for the purpose of building specialized dictionaries. A simple example, i.e., program, will serve as a basis for showing how relationships between terms are captured in both approaches. My aim is to dem...

We describe a method to automatically extract hyponyms from Japanese newspapers. First, we discover patterns which can extract hyponyms of a noun, such as "A nado-no B (B such as A)", then we apply the patterns to the newspaper corpus to extract instances. The procedure works best to extract hyponyms of concrete things in the middle of the word hierarchies. The precision is 49-87 percent depend...

Charisma, the ability to attract and retain followers without benefit of formal authority, is more difficult to define than to identify. While we each seem able to identify charismatic individuals – and non-charismatic individuals – it is not clear what it is about an individual that influences our judgment. This paper describes the results of experiments designed to discover potential correlat...

Most previous studies in computerized deception detection have relied only on shallow lexico-syntactic patterns. This paper investigates syntactic stylometry for deception detection, adding a somewhat unconventional angle to prior literature. Over four different datasets spanning from the product review to the essay domain, we demonstrate that features driven from Context Free Grammar (CFG) par...

In this paper we study a graph-based approach to the task of Recognizing Textual Entailment between a Text and a Hypothesis. The approach takes into account the full lexico-syntactic context of both the Text and Hypothesis and is based on the concept of subsumption. It starts with mapping the Text and Hypothesis on to graph structures that have nodes representing concepts and edges representing...

The traditional binary notion of grammaticality is more and more often replaced by intermediate levels of acceptability, also called gradience. This paper aims to provide a numerical account of syntactic gradience. It introduces and investigates a numerical model with which acceptability can be predicted by factors derivable from the output of a parser. Its performance is compared to other expe...
