Object-attribute-value-relationships, which are a frequently used data structure to code real-world problems,are formalized via many-valued contexts in formal concept analysis (FCA). The aim of FCA is to explore (formal) concepts from empirical data contexts. A concept of a context consists of two parts: the extent (objects the concept covers) and the intent (attributes describing the concept). From...
The sentence similarity computation plays an significant role in the fields of Chinese language processing. The paper presents a new approach to calculate the Chinese question semantic similarity, which is divided into two steps: the first step is to disambiguate the word sense in the question, and the second step is to compute the question semantic similarity based on the word sense. This paper uses...
Automatic differentiation is the primary means of obtaining analytic derivatives from a numerical model given as a computer program. Therefore, it is an essential productivity tool in numerous computational science and engineering domains. Computing gradients with the adjoint (also called reverse) mode via source transformation is a particularly beneficial but also challenging use of automatic differentiation...
Mobile agents are increasingly play significant role in distributed information systems. This article addresses the problem that happens when a mobile agent leaves a group and wants to join another one. Therefore, it has to follow different polices which may have conflicts with its own requirements. The paper studies the problem from cooperative management point of view and goes to the technological...
As computers and software applications become ubiquitous the systems we build are increasingly required to run on not just a single piece of hardware, but rather be available for different platforms, different types of hardware and offer different modes of interaction depending on the context of use. Within a formal development process when we consider refinement for interactive systems we therefore...
A computer simulation process of Emotion is viewed as a complete course of events by theory of affective computing flow. Based on this theory, the use of existing multi-agent technology and learning theory will achieve the model of affective computing in the computer, single-agent structure in the system of individual learners used to simulate learner in the learning process emotional excitation process,...
This paper presents the use of full-context video to motivate and aid non-literate, first-time users of PCs to successfully navigate a computer application with minimal assistance. Following previous work focused on non-literate users, we observed that in spite of our subjects' understanding of the UI mechanics, they experienced barriers beyond illiteracy in interacting with the computer: lack of...
