The organization of unstructured data is recognized as one of the major uncertain problems in the information industry and data mining paradigm. It will be in the form of computerized information that moreover, does not have a data model and there are not simply used by data mining. The task of managing unstructured data signifies possibly the major data management opportunity for our community...

Most workflow tools support structured workflows despite the fact that unstructured workflows can be more expressive. The reason for this is that unstructured workflows are more prone to errors. In this paper, we describe a taxonomy that serves as a framework for analyzing unstructured workflows. The taxonomy organizes unstructured workflows in terms of two considerations: improper nesting and ...

A novel state dependent control approach for discrete-time nonlinear systems with general performance criteria is presented. This controller is robust for unstructured model uncertainties, resilient against bounded feedback control gain perturbations in achieving optimality for general performance criteria to secure quadratic optimality with inherent asymptotic stability property together with ...

We showcase the KnowledgeStore (KS), a scalable, fault-tolerant, and Semantic Web grounded storage system for interlinking unstructured and structured contents. The KS contributes to bridge the unstructured (e.g., textual document, web pages) and structured (e.g., RDF, LOD) worlds, enabling to jointly store, manage, retrieve, and query, both typologies of contents.

System performance analysis is typically conducted by collecting structured data in the form of metrics or by examining unstructured data in the form of logs. Tools currently available either analyze the structured data or the unstructured data, but not both. In some settings, this is not enough to make meaningful statements about the performance of the system. In this work, we explore alternat...

This study found mixed support for the hypothesis that the difference in criterion-related validity between unstructured and structured employment interviews is due solely to the greater reliability of structured interviews. Using data from prior meta-analyses, this hypothesis was tested in 4 data sets by using standard psychometric procedures to remove the effects of measurement error in inter...

The present study aims to investigate the quality of the structured versus unstructured abstracts in terms of content comprehensiveness and observing the items in APA manual.This survey uses a content analysis method. Data were collected through study of abstracts. Journals included in this study are as follows: Faslname-ye Ketab, Journal of Academic Librarianship and Information Science, Irani...

We study the perturbation theory of structured matrices under structured rank one perturbations, and then focus on several classes of complex matrices. Generic Jordan structures of perturbed matrices are identified. It is shown that the perturbation behavior of the Jordan structures in the case of singular J-Hamiltonian matrices is substantially different from the corresponding theory for unstr...
