生物语言学研究前景广阔     生物语言学  语言官能进化  语言进化与变异       font style='font-size:12px;'> 2022/3/7
生物语言学研究作为一种跨学科、多领域、综合性研究,主要关注人类语言的生物属性,涵盖生物学、语言学、人类学、考古学、解剖学、计算机科学、心理学等多个领域。其根源最早可以追溯到15世纪的文艺复兴时期达芬奇将语言看作人类的一种生物机能的假设。但是,在当时的认知和现实条件下,并没有也不可能给出一个专门的术语对这种假设进行描述。在达尔文之后的探索中,ClarenceL.Meader和JohnH.Muyske...
二声调方言红古话声调的声学分析     兰银官话  红古话  二声调  声学实验  音高聚类分析       font style='font-size:12px;'> 2017/8/21
红古话是目前确知只有两个单字调的极少数汉语方言点之一。本文对4名发音人的声调进行声学实验分析,通过对音高曲线的考察和对音高数据的聚类分析,将红古话声调的调值处理为第一声(平去声)24;第二声(上声)53。
What Is Not in the Bag of Words forWhy-QA?     QA  signifi  cantly higher scores       font style='font-size:12px;'> 2015/9/8
While developing an approach to why-QA, we extended a passage retrieval system that uses offthe-shelf retrieval technology with a re-ranking step incorporating structural information. We get signi...
Induction and Comparison     Induction  Comparison       font style='font-size:12px;'> 2015/9/2
Frege proved an important result, concerning the relation of arithmetic to second-orderlogic, that bears on several issues in linguistics. Frege’s Theorem illustrates the logic of relations like PRECE...
We continue some steps showing the distinctions and proximities of languages over statistical facts as it has been pioneered previously [3]. In the paper, we construct the homology tree from the dista...
Position,direction,and their perceptual integrality     Position  direction  perceptual integrality       font style='font-size:12px;'> 2015/6/25
Subjects were shown an arrow inside a rectangle and were asked to decide on either its vertical direction (up vs. downl or its height (high vs. low) as quickly as possible. Whenever vertical direction...
The Leaky Competing Accumulator (LCA) is a biologically inspired model of choice. It describes the processes of leaky accumulation and competition observed in neuronal populations during choice tasks ...
When learning addition, children appear to perform a remarkable feat: as they practice counting out sums on their fingers, they discover more efficient strategies while avoiding conceptually flawed pr...
Rappin on the Copula Coffin:Theoretical and Methodological Issues in the Analysis of Copula Variation in African American Vernacular English.
While methods for parsing probabilistic context-free grammars (PCFGs) are well known, a tabular parsing framework for arbitrary PCFGs which allows for botton-up, topdown, and other parsing strategies...
Computing PageRank using Power Extrapolation     Computing PageRank  Power Extrapolation       font style='font-size:12px;'> 2015/6/12
We present a novel technique for speeding up the computation of PageRank, a hyperlink-based estimate of the “importance” of Web pages, based on the ideas presented in [7]. The original PageRank algori...
This paper studies the properties and performance of models for estimating local probability distributions which are used as components of larger probabilistic systems — history-based generative parsi...
Log-Linear Models for Label Ranking     Log-Linear Models  Label Ranking       font style='font-size:12px;'> 2015/6/12
Label ranking is the task of inferring a total order over a predefined set of labels for each given instance. We present a general framework for batch learning of label ranking functions from supervis...
Contrary to linear difference equations, there is no general theory of difference equations of the form G(P(x − τ1),..., P(x − τs)) +G0(x) = 0, with τi ∈ K, G(x1,..., xs) ∈ K[x1,..., xs] o...
Mathematical ability is heritable, but few studies have directly investigated its molecular genetic basis. Here we aimed to identify specific genetic contributions to variation in mathematical ability...
