Human factors have been increasingly recognized as one of the major driving forces of requirement changes. We believe that the requirements elicitation (RE) process should largely embrace human-centered perspectives, and this work focuses on changing human intentions and desires over time. To support software evolution due to requirement changes, Situ framework has been proposed to model and de...

It is well-known that the notion of (strong) conditional independence (CI) is too restrictive to capture independencies that only hold in certain contexts. This kind of contextual independency, called context-strong independence (CSI), can be used to facilitate the acquisition, representation, and inference of probabilistic knowledge. In this paper, we suggest the use of contextual weak indepen...

In the study of the meaning of natural language expressions, the sentence level provides a natural entry point. Its relevance depends, of course, on the focus we want to put on meaning: as related to thought, to communication, to truth, etc. In this paper, we concentrate on the model theoretic view of meaning, in particular via first-order logic representation. This view is commonly referred to...

In this paper we present a new dataflow execution model called semi-static dataflow. This model incorporates aspects of conventional static and dynamic dataflow architectures. Programs are partitioned into a collection of dataflow graphs. The execution of each of these graphs is the responsibility of a low-level process called a context. The static dataflow execution model is used to evaluate e...

the notion of a $d$-poset was introduced in a connection withquantum mechanical models. in this paper, we introduce theconditional expectation of  random variables on thek^{o}pka's $d$-poset and prove the basic properties ofconditional expectation on this  structure.

in this paper, we determine the structure of the space of multipliers of the range of a composition operator cφ that induces by the conditional expectation between two lp() spaces.

Successful language acquisition hinges on organizing individual words into grammatical categories and learning the relationships between them, but the method by which children accomplish this task has been debated in the literature. One proposal is that learners use the shared distributional contexts in which words appear as a cue to their underlying category structure. Indeed, recent research ...
