We present an approach to enhancing information access through web structure mining in contrast to traditional approaches involving usage mining. Specifically, we mine the hardwired hierarchical hyperlink structure of websites to identify patterns of term-term cooccurrences we call web FDs (functional dependencies). Intuitively, a web FD ‘x → y’ declares that all paths through a site involving ...

Functional Dependencies (FDs) are a common constraint for many applications. Specifying FDs in XML documents, however, is difficult because XML documents do not have uniform structures. We introduce XML Template Functional Dependencies (XTFDs), which can specify FDs in XML documents, in this paper. Previously, we defined XTFDs in terms of variables only (Mok, 2005). In this paper, we extend our...

In this paper, a type of response spectra in which fatigue damage is the ordinate is reviewed. Computation of this Fatigue Damage Spectrum (FDS) in both the time and frequency domains is discussed. The method of Fatigue Damage Equivalent vibration Testing (FDET) is discussed using the FDS as the measure of environment severity. Improvements in each technique over previous work are introduced an...

We investigate the profile of the blowing up solutions to the nonlinear nonlocal system (FDS) u′(t) + Dα0+(u − u0)(t) = |v(t)|q, t > 0, v′(t) + Dβ0+(v − v0)(t) = |u(t)|p, t > 0, where u(0) = u0 > 0, v(0) = v0 > 0, p > 1, q > 1 are given constants and Dα0+ and Dβ0+ , 0 < α < 1, 0 < β < 1 stand for the Riemann-Liouville fractional derivatives. Our method of proof relies on comparisons of the solu...

Fourier Domain Scoring (FDS) has been shown to give a 60% improvement in precision over the existing vector space methods, but its index requires a large storage space. We propose a new Web text mining method using the discrete cosine transform (DCT) to extract useful information from text documents and to provide improved document ranking, without having to store excessive data. While the new ...

BACKGROUND Several noninvasive predictive models were developed to substitute liver biopsy for fibrosis assessment. AIM To evaluate the diagnostic value of fibronectin which reflect extracellular matrix metabolism and standard liver functions tests which reflect alterations in hepatic functions. MATERIAL AND METHODS Chronic hepatitis C (CHC) patients (n = 145) were evaluated using ROC curve...

One of the most important steps in obtaining a relational model from legacy systems is the extraction of functional dependencies (FDs) through data mining techniques. Several methods have been proposed for this purpose and most use direct search methods that traverse the search space in exponential time in the number of attributes of the relation. As it is not uncommon to find in practice relat...

Learning Objects (LOs) play a key role for supporting eLearning. In general, however, the development of LOs remains a vague issue, because there is still no clearly defined and widely adopted LO specification and development methodology. We combined two technological paradigms (feature diagrams (FDs) and generative techniques) into a coherent methodology to enhance reusability and productivity...
