Acceptability Prediction by Means of Grammaticality Quantification

by Barbara Hemforth, Stéphane Rauzy
"... We propose in this paper a method for quantifying sentence grammaticality. The approach based on Property Grammars, a constraint-based syntactic formalism, makes it possible to evaluate a grammaticality index for any kind of sentence, including ill-formed ones. We compare on a sample of sentences th ..."

the grammaticality indices obtained from PG formalism and the acceptability judgements measured by means of a psycholinguistic analysis. The results show that the derived grammaticality index is a fairly good tracer of acceptability scores. 1

Maximum Likelihood Phylogenetic Estimation from DNA Sequences with Variable Rates over Sites: Approximate Methods

by Ziheng Yang - J. Mol. Evol , 1994
"... Two approximate methods are proposed for maximum likelihood phylogenetic estimation, which allow variable rates of substitution across nucleotide sites. Three data sets with quite different characteristics were analyzed to examine empirically the performance of these methods. The first, called ..."

the "discrete gamma model," uses several categories of rates to approximate the gamma distribution, with equal probability for each category. The mean of each category is used to represent all the rates falling in the category. The performance of this method is found to be quite good

A Quantification Model of Grammaticality

by Blache, Philippe, Prost, Jean-Philippe - PROCEEDINGS OF THE FIFTH INTERNATIONAL WORKSHOP ON CONSTRAINTS AND LANGUAGE PROCESSING (CSLP2008) , 2008
"... Abstract. 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 c ..."

The Impact of the Potential Duration of Unemployment Benefits on the Duration of Unemployment

by L.F. Katz, Lawrence F. Katz, Bruce D. Meyer, Dale Mortensen, Nick Stern - Journal of Public Economics , 1997
"... This paper uses two data sets to examine the impact of the potential duration of unemployment insurance (UI) benefits on the duration of unemployment and the time pattern of the escape rate from unemployment in the United States. The first part of the empirical work uses a large sample of househ ..."

that policies that extend the potential duration of benefits increase the mean duration of unemployment by substantially more than policies with the same predicted impact on the total UI budget that raise the level of benefits while holding potential duration constant.

VALIDATING THE PERMUTATIONAL TEST OF GRAMMATICALITY*

by Robert Ian Scott, John A. Mills
"... The permutational test of grammaticality employs the notion of a kernel sentence, defined as subject-verb-object-qualifier (SVOQ). Three experiments are reported leading to the following conclusions: (1) an index measuring progressive disruption of the kernel yielded Pearson r’s of.65 to.84 with mea ..."

) When the index is relatively high, word order alone predicts mean grammatical judgments. (4) The level of meaningfulness of the constituent words of a sentence exerts a moderating influence on effect (2). For the purpose of the present study, the term grammaticality will be defined as those non

Gradient phonological acceptability as a grammatical effect

by Adam Albright , 2007
"... Phonological judgments are often gradient: blick>?bwick> *bnick. The theoretical interpretation of gradient acceptability remains controversial, however, with some authors maintaining that it is a performance/task effect based on similarity to the lexicon (neighborhood effects), and others att ..."

The Meaning of Free Choice

In this paper, I discuss the distribution and interpretation of free choice items (FCIs) in Greek, a language exhibiting a lexical paradigm of such items distinct from that of negative polarity items. Greek differs in this respect from English which uniformly employs any. FCIs are grammatical only i ..."
