Metric systems for semantics, or semantic cognitive maps, are allocations of words or other representations in a metric space based on their meaning. Existing methods for semantic mapping, such as Latent Semantic Analysis and Latent Dirichlet Allocation, are based on paradigms involving dissimilarity metrics. They typically do not take into account relations of antonymy and yield a large number...

Capturing physical data in the context of measurement systems is a demanding process that often requires many repetitions with different settings. To assist in this activity, a domain-specific modeling language (DSML) called Sequencer has been developed to enable the improved definition of measurement procedures. With Sequencer, the level of abstraction has been raised and sophisticated changes...

To facilitate the use of syntactic information in the study of child language acquisition, a coding scheme for Grammatical Relations (GRs) in transcripts of parent-child dialogs has been proposed by Sagae, MacWhinney and Lavie (2004). We discuss the use of current NLP techniques to produce the GRs in this annotation scheme. By using a statistical parser (Charniak, 2000) and memorybased learning...

An algebraic structure is a set with one or more operations defined on it. For example, the natural numbers with addition and multiplication are such a structure. An algebraic structure A is a Boolean algebra if it has two binary operations (∗ and +), one unary operation (∼), and two designated elements (0 and 1) such that for any x, y and z from A (x, y and z are variables whose domain is the ...

In the era of structural biology, it is necessary to apply efficient and effective tools in order to measure structural similarity between proteins. Although a great number of structural comparison methods have been developed, none of them gives an exact solution to the problem. In this paper, we introduce a novel method for structural similarity measurement of proteins based on language modeli...

Recently, researchers have suggested that deficits in working memory capacity contribute to language-processing difficulties observed in individuals with aphasia (e.g., I. Caspari, S. Parkinson, L. LaPointe, & R. Katz, 1998; R. A. Downey et al., 2004; N. Friedmann & A. Gvion, 2003; H. H. Wright, M. Newhoff, R. Downey, & S. Austermann, 2003). A theoretical framework of working memory can aid in ...

Feldman et al. criticize the MacArthur Communicative Development Inventories (CDIs) as having too much variability, too little stability, and insufficient ability to predict early language delay. We present data showing that these characteristics of the CDI are authentic reflections of individual differences in early language development rather than measurement deficiencies. We also respond to ...

The dramatic increase in the U.S. Latino population in recent decades has spurred an equally dramatic rise in bilingual survey instruments used by scholars to gauge the political attitudes of this growing ethnic group. A key assumption behind these instruments is that English-language items tap the same political constructs as their Spanish-language analogs. This paper reports evidence which su...
