World Wide Web is the biggest repository that contains all sorts of information. User can search necessary information from the web. All the information in the WWW are unstructured and human readable. Search engine provides result based on the user query is not satisfactory due to unstructured and semi-structured nature of web document. The advent of semantic web overcomes this difficulty, the ...

A BPMN model is well-structured if splits and joins are always paired into single-entry-single-exit blocks. Well-structuredness is often a desirable property as it promotes readability and makes models easier to analyze. However, many process models found in practice are not well-structured, and it is not always feasible or even desirable to restrict process modelers to produce only well-struct...

Unstructured overlay networks are driven by simple protocols that are easy to analyze and implement. The lack of structure, however, leads to weak message delivery guarantees and poor scaling. Structured overlays impose a global overlay topology that is then maintained by all peers in a complex protocol. In contrast to unstructured approaches the structured overlays are efficient and scalable, ...

Graph Neuron (GN) is a network-centric algorithm which envisages a stable and structured network of tiny devices as the platform for parallel distributed pattern recognition. However, the unstructured and often dynamic topology of a wireless sensor network (WSN) does not allow deployment of such applications. In this paper, using GN as a testbed application, we show that a simple virtual topolo...

Huge amount of information is hidden within unstructured text. This information is often best exploited in structured or relational form, which is suited for many applications including Information Extraction. Information Extraction is the task of automatically extracting structured information from a given set of information thus producing a well-defined categorized data from unstructured mach...

This work is related with the implementation of a finite volume method to solve the 2D Shallow Water Equations on Graphic Processing Units (GPU). The strategy is fully oriented to work efficiently with unstructured meshes which are widely used in many fields of Engineering. Due to the design of the GPU cards, structured meshes are better suited to work with than unstructured meshes. In order to...

Multiblock structured meshes offer better computational efficiency than the unstructured meshes which, on the other hand, are more flexible for complex geometries. The multiblock structured meshing could be more useful if the partitioning of the domain can be performed automatically. In this paper, we consider various automated blocking approaches for some turbomachinery zones. We then assess t...

This study evaluated the effect of distance on the likelihood of initiating and maintaining regular use of a fitness-program benefit in a population of managed Medicare seniors. We studied 8,162 participants and nonparticipants in a managed-care fitness-program benefit: a structured group exercise program or an unstructured health-club membership. Participants in both programs lived significant...

Business process models capture process requirements that are typically expressed in unstructured, directed graphs that specify parallelism. However, modeling guidelines or requirements from execution engines may require that processes models are structured in blocks. The goal of this paper is to define an automated method to convert an unstructured process model containing parallelism into an ...

We present a model which allows to define in an uniform way information quality dimensions related to heterogeneous types of information, such as structured data managed in data bases, semi-structured and unstructured texts and images. We first define a set of concepts that allow to represent several basic characteristics of such heterogeneous types of information. Then, we introduce a general ...
