the realization optimality theory is a recent development in the original optimality theory which is proposed to deal with morphological issues especially the inflectional ones. its main idea is to consider the morphological realization rules as ranked violable language-specific constraints that control the realization processes and provide phonological information of grammatical morphemes. thi...

In this paper, we suggest a novel recommender system where set of appropriate propositions is formed by measuring how user query features are close to space all possible propositions. The for e-traders selling commodities. A commodity has hierarchical-structure properties which mapped the respective numerical scales. scales normalized so that from potential customer and any proposition e-trader...

The constraint complexity of a graphical realization of a linear code is the maximum dimension of the local constraint codes in the realization. The treewidth of a linear code is the least constraint complexity of any of its cycle-free graphical realizations. This notion provides a useful parametrization of the maximum-likelihood decoding complexity for linear codes. In this paper, we prove the...

It is shown that the so-called \pure" mixed H 2 =H 1 optimization problem does not have a \good" solution. More precisely, a class of non-singular \pure" mixed H 2 =H 1 optimization problems (minimization of an L 2-norm subject to a Youla parameterization and an L 1 constraint) is considered. It is shown that, whenever the L 1 constraint is not redundant, the optimal controller has innnite orde...

In this study it is argued that the omission of closed class morphemes and of unstressed syllables within words is related to their common characteristic, viz. that they are unstressed, rhythmically weak parts of utterances. Several strands of evidence indicate that it is unlikely that children are unable to perceive these elements in the input speech. The pattern of (non)realization of unstres...

In this paper we investigate the consistency of parameter estimates obtained from least squares identification with a quadratic parameter constraint. For generality, we consider infinite impulse response systems with colored input and output noise. In the case of finite data, we show that there always exists a possibly indefinite quadratic constraint depending on the noise realization that yiel...

Standard Functional Uniication Grammars (FUGs) provide a structurally guided top-down control regime for sentence generation. When using FUGs to perform content realization as a whole, including lexical choice, this regime is no longer appropriate for two reasons: (1) the uniication of non-lexicalized semantic input with an integrated lexico-grammar requires mapping \\oating" semantic elements ...
