The inherent complexity of the software systems creates problems in the software engineering industry. Numerous techniques have been designed to comprehend the fundamental characteristics of software systems. To understand the software, it is necessary to know about the complexity level of the source code. Cognitive informatics perform an important role for better understanding the complexity o...

Site complexity has been defined both as a single construct and as multi-dimension construct and operationalized in terms of objective measures or user perceptions. In this research, we distinguish between objective and subjective (perceived) site complexity and examine the relationship between the two. Objective site complexity is measured by how varied a website is; subjective site complexity...

This paper presents a class of dependency-based for-real grammars (FODG) which can be parametrized by two different but similar measures of non-projectivity. The measures allow to formulate constraints on the degree of word-order freedom in a language described by a FODG. We discuss the problem of the degree of word-order freedom which should be allowed ~, a FODG describing the (surface) syntax...

The foundation for network process evolution research is the modeling of network structure and behavior complexity. With such a model, network systems can be directed toward acquiring good maintainability attributes according to the principles of engineering. In this paper, a Process Management Network (PMN) model is developed to acquire directly from the target process codes the knowledge hidd...

MOTIVATION It is well known that the regulatory regions of genomes are highly repetitive. They are rich in direct, symmetric and complemented repeats, and there is no doubt about the functional significance of these repeats. Among known measures of complexity, the Ziv-Lempel complexity measure reflects most adequately repeats occurring in the text. But this measure does not take into account is...

ÐWe studied a number of measures that characterize the difficulty of a classification problem, focusing on the geometrical complexity of the class boundary. We compared a set of real-world problems to random labelings of points and found that real problems contain structures in this measurement space that are significantly different from the random sets. Distributions of problems in this space ...

Biometric control of access to places, restricted information or personal data is an increasingly important consideration in many situations. The handwritten signature is a common biometric which has been in regular use, but with authentication decisions traditionally made by human visual inspection. This paper investigates several issues relating to signature complexity and authentication deci...
