This paper focuses on the sharing of phonolog-ical information in a multilingual inheritance-based lexicon. It explores the possibility of establishing a phoneme inventory for a group of languages in which language-speciic phonemes function as \allophones" of newly deened meta-phonemes. Danish, Dutch, English, and Ger-man were taken as a test bed and their vowel phoneme inventories were studied...

This chapter presents a novel framework for tuning the parameters of Evolutionary Algorithms. A hybrid technique combining Meta-EAs and statistical Racing approaches is developed, which is not only capable of effectively exploring the search space of numerical parameters but also suitable for tuning symbolic parameters where it is generally difficult to define any sensible distance metric.

To build a data-integration system, the application designer must specify a mediated schema and supply the descriptions of data sources. A source description contains a source schema that describes the content of the source, and a mapping between the corresponding elements of the source schema and the mediated schema. Manually constructing these mappings is both labor-intensive and error-prone,...

A system with a metaobject protocol (MOP) allows programmers to extend it and then use the extended system as naturally as the original non-extended one. Such metaobject protocols often use a metacircular architecture to make the extensions easier to write. Unfortunately, this use of metacircularity can lead to problems stemming from a conflation of the extended and non-extended functionalities...

This paper presents the meta-morphing model and its practical application in an industry strength business intelligence solution. The meta-morphing model adds associations between measures and dimensions to a traditional multidimensional cube model, and thus facilitates a process where users are able to ask questions to a business intelligence (BI) system without the constraints of a traditiona...

The goal of this paper is to identify key financial and accounting variables that can accurately classify Green IT leaders against Green IT followers. The detailed objectives are: (i) to build and compare single and meta classifiers to identify the relationship between environmental performance and financial performance; (ii) to select and interpret a final prediction model with a smaller set o...

We present the basic principles and possible applications of systems capable of meta-reasoning and reflection. After a discussion of the seminal approaches, we outline our own perception of the state of the art, mainly but not only in computational logic and logic programming. We review relevant successful applications of meta-reasoning, and the basic underlying semantic principles.

It is well known that a formal framework for the schema matching problem (SMP) is important because it facilitates the building of algorithm model and the evaluation of algorithms. An algebraic framework for schema matching is developed in this paper. First, based on universal algebra, we propose a meta-meta structure for schema, which is named multi-labeled schema. This definition has a distin...

This paper describes a model of learning stages called OCTR. Learning under OCTR advances gradually as the degree of social context increases. Furthermore, OCTR can also serve as a framework for describing the cognitive development and motivation of students, categorizing many existing teaching strategies, and better understanding how to introduce meta-cognition and attitude in systems for educ...
