A corpus-based knowledge representation system consists of a large collection of disparate knowledge fragments or schemas, and a rich set of statistics computed over the corpus. We argue that by collecting such a corpus and computing the appropriate statistics, corpus-based representation offers an alternative to traditional knowledge representation for a broad class of applications. The key ad...

There is an increasing number of linguists interested in large syntactically annotated corpora (treebanks). Such corpora can serve as a base for statistical applications and, at the same time, may be used in theoretical linguistics as a source for investigations about language use. The most important treebank nowadays is the Penn Treebank (Marcus et al., 1993; Marcus et al., 1994). Many statist...

A recent practice in the study of language on teacher education programmes has been the use of electronic corpora, and we are therefore still at the initial stages of exploring key issues relating to their integration. Despite arguments for and against their adaptation, there is a dearth of evaluative research examining student teachers’ perceptions of learning and teaching through corpus-based...

What is a web-based corpus and what is web-based corpus software? The answer is, strictly speaking, that there is no such thing as web-based corpus software. However, one should not be discouraged by this rather negative assessment. In fact, if one examines the title closely, different bracketings of the phrase might suggest interesting possibilities. For example, if one chooses to write it as ...

With this scheme, a simple processor might take 4 cycles per instruction (CPI = 4). processors, such as IBM's 801 research prototype, the MIPS R2000 (based on to pipeline a RISC because its reduced instruction set means the instructions This simple (and fun) classification of design styles first appeared in a 1993. The two processor classifications are the Reduced Instruction Set Computer The p...

Broad-coverage grammars tend to be highly ambiguous. When such grammars are used in a restricted domain, it may be desirable to specialize them, in effect trading some coverage for a reduction in ambiguity. Grammar specialization is here given a novel formulation as an optimization problem, in which the search is guided by a global measure combining coverage, ambiguity and grammar size. The met...

Lexicon is in important resource in any kind of language processing application. Corpus-based lexica have several advantages over other traditional approaches. The lexicon developed for Sinhala was based on the text obtained from a corpus of 10 million words drawn from diverse genres. The words extracted from the corpus have been labeled with parts of speech categories defined according to a no...

Variation in the spelling of names has various origins, many of which many are difficult to describe by rule. We present a method that uses both rules and a similarity measure of a probabilistic nature, and which can make use of existing onomastic corpora. Rules first convert an unknown name to a semiphonemic form. Then a selection is made of possible candidates in the onomastic corpus. For thi...

The purpose of this study was to assess the effectiveness of CALL in developing reading proficiency of Iranian EFL learners in comparison to paper-based instruction and to investigate any significant difference in the reading comprehension of the high and low proficient learners after receiving computer-assisted instruction (CAI). This study also investigated the participants’ attitudes toward ...
