The present article investigates the fusion of different language models to improve translation accuracy. A hybrid MT system, recentlydeveloped in the European Commissionfunded PRESEMT project that combines example-based MT and Statistical MT principles is used as a starting point. In this article, the syntactically-defined phrasal language models (NPs, VPs etc.) used by this MT system are supp...

For assessing conceptual data model quality it is useful to have quantitative and objective measurement instruments. The scarcity of such measurement instruments leaded us to define a set of measures for structural complexity, an internal quality attribute of conceptual data models, with the idea that it is related to the external quality of such models. In order to gather empirical evidence th...

This paper deals with the problem of identifying direct causal effects in recursive linear structural equation models. The paper provides a procedure for solving the identification problem in a special class of models.

A recent article in the Journal of Management gives a critique of a Bayesian approach to factor analysis proposed in Psychological Methods. This commentary responds to the authors’ critique by clarifying key issues, especially the use of priors for residual covariances. A discussion is also presented of cross-loadings and model selection tools. Simulated data are used to illustrate the ideas. A...

In this literature, the symmetric inverse generalized eigenvalue problem with submatrix constraints and its corresponding optimal approximation problem are studied. A necessary and sufficient condition for solvability is derived, and when solvable, the general solutions are presented.

Despite prolific research on IT business value, this stream of research still encounters considerable limitations such as inconsistent findings of the direct link between IT and firm profitability and the demonstration of the indirect relationship between IT and specific aspects of firm value without explicitly considering network environments. To overcome the limitations caused by utilizing th...

Introduction Over the last decade there has been a growing interest in the market orientation concept (Day, 1992; Grönroos, 1989; Webster, 1988, 1992) and its usefulness in increasing businesses’ economic performance (Jaworski and Kholi, 1993; Narver and Slater, 1990; Reukert 1992). In most studies market orientation is defined as either the adoption of a marketing concept (see Deng and Dart, 1...
