We consider the problem of multiple descriptions (MD) source coding and propose new coding strategies involving both unstructured and structured coding layers. Previously, the most general achievable rate-distortion (RD) region for the l-descriptions problem was the Combinatorial Message Sharing with Binning (CMSB) region. The CMSB scheme utilizes unstructured quantizers and unstructured binnin...

Exception directed acyclic graphs (EDAGs) are knowledge structures that subsume trees and rules but can be substantially more compact. Manually constructed and induced EDAGs are compared by reconstructing Shapiro’s “structured induction” of a chess end game. It is shown that the induced EDAG is very similar to that produced through consultation with exnerts and that both are small. comorehensib...

Building well-structured business process models (similar to writing well-structured controlflow blocks in a programming language) is often recommended in order to raise the quality and readability of such models. This article discusses patterns that are related to structured and unstructured business process models. One kind of these patterns deals with situations where some part of the model ...

The staples of information retrieval have been querying and search, respectively, for structured and unstructured repositories. Processing queries over known, structured repositories (e.g., Databases) has been well-understood, and search has become ubiquitous when it comes to unstructured repositories (e.g., Web). Furthermore, searching structured repositories has been explored to a limited ext...

The control of robotic manipulators has become important due to the development of the flexible automation. Requirements such as the high speed and high precision trajectory tracking make the modern control indispensable for versatile applications of manipulators (Middleton & Goodwin, 1998; Ortega & Spong, 1999; Popescu et al., 2008). Rigid robot systems are subjects of the research in both rob...

Traditional scientific papers are unstructured documents, which are difficult to meet the requirement of structured retrieval, statistical classification and association analysis and other high-level application. Hence, how to extract and analyze the structured information of the papers becomes a challenging problem. A structured information extraction algorithm is proposed for unstructured and...
