This paper describes the design of six publicly available biomedical corpora. We then present usage data for the six corpora. We show that corpora that are carefully annotated with respect to structural and linguistic characteristics and that are distributed in standard formats are more widely used than corpora that are not. These findings have implications for the design of the next generation...

The Virtual Usability Laboratory (VUL) is a software tool developed to remotely capture and analyze a wide variety of usage data on Web-based educational games and simulations. The VUL allows for automated remote collection and integration of such data as user activity logs, on-line demographic questionnaire responses, and data from automatically triggered pop up questions at critical points in...

The core question at the heart of nearly all work in cognitive / usage-based linguistics is, how do characteristics of the cognitive system affect, or at least correlate with, the acquisition, representation, processing, use, and change of language? Thus, ever since Lakoff's (1990:40) formulation of the cognitive commitment – the "commitment to providing a characterization of general principles...

In this paper, first, an initial feature vector for vocal fold pathology diagnosis is proposed. Then, for optimizing the initial feature vector, a genetic algorithm is proposed. Some experiments are carried out for evaluating and comparing the classification accuracies which are obtained by the use of the different classifiers (ensemble of decision tree, discriminant analysis and K-nearest neig...

In spite of the significant evolution of spelling and grammar checkers for word-processing software, the problem of judging the appropriateness of language usage in different contexts remains to a large extent still unsolved. This paper presents a novel, argumentative approach to providing proactive assistance for language usage assessment on the basis of the web linguistic corpus. A defeasible...

Frequency distribution of word usage in a word sequence generated by capping is estimated in terms of the number of "hits" in retrieval of web-pages, to evaluate structure of semantics proper not to a particular text but to a language. Especially we compare distribution of English sequences with Japanese ones and obtain that, for English and Japanese phonogram, frequency of word usage against r...

The purpose of this chapter is to highlight empirical evidence for the presence and persistence of self in individuals with Alzheimer’s disease. First, the authors review their previous findings (Fazio & Mitchell, 2009) that revealed the persistence of self via language usage and delayed visual self-recognition data. Second, the authors present previously unpublished data demonstrating that bot...

As the number and size of computer corpora grow, linguistic researchers are increasingly using them to study changes in language over time. Comparing usage at one point in time with usage at a later or an earlier period seems a stunningly simple and Sausurreanly impeccable method of studying language change. Needless to say the reality is rather different. This paper identifies some of the meth...

Software systems use text based log files for many different applications, such as monitoring events, or in the case of a research setting, capturing the usage data from a user study. The downfall with these text based log files is that even if they are well structured (using XML or the similar), they are difficult to read and even more difficult to get meaningful information from. To help extr...

This paper describes the architecture of costa, an abstract interpretation based cost and termination analyzer for Java bytecode. The system receives as input a bytecode program, (a choice of) a resource of interest and tries to obtain an upper bound of the resource consumption of the program. costa provides several non-trivial notions of cost, as the consumption of the heap, the number of byte...
