Knowledge Representation and the Semantics of Natural Language

The booklet provides an interdisciplinary method of wisdom illustration and the therapy of semantic phenomena of common language, that is located among synthetic intelligence, computational linguistics, and cognitive psychology. The proposed approach is predicated on Multilayered prolonged Semantic Networks (MultiNets), that are used for theoretical investigations into the semantics of common language, for cognitive modeling, for describing lexical entries in a computational lexicon, and for ordinary language processing (NLP).

Web data mining: Exploring hyperlinks, contents, and usage data

Net mining goals to find invaluable details and information from net links, web page contents, and utilization information. even though net mining makes use of many traditional info mining innovations, it's not in simple terms an program of conventional info mining as a result of the semi-structured and unstructured nature of the internet info.

Semantic Models for Multimedia Database Searching and Browsing

Semantic types for Multimedia Database looking out and skimming starts off with the creation of multimedia info purposes, the necessity for the improvement of the multimedia database administration platforms (MDBMSs), and the $64000 concerns and demanding situations of multimedia structures. The temporal kin, the spatial family members, the spatio-temporal relatives, and a number of other semantic types for multimedia details structures also are brought.

Enterprise Content Management in Information Systems Research: Foundations, Methods and Cases

This publication collects ECM study from the educational self-discipline of knowledge structures and similar fields to help teachers and practitioners who're attracted to knowing the layout, use and impression of ECM platforms. It additionally offers a beneficial source for college kids and academics within the box. “Enterprise content material administration in details structures learn – Foundations, equipment and instances” consolidates our present wisdom on how today’s agencies can deal with their electronic details resources.

Sample text

For example, we generate marked coefficients v 1 and v 2 close to v1 and v2 such that v 1 > v 2 to embed a “1” and v 1 ≤ v 2 to embed a “0” [63]. One can also enforce signs to embed a “1” or “0”, as used in [64, 65]. Extending the basic ways of enforcement, more sophisticated schemes can be designed and/or analyzed [96]. Many proposed schemes in the literature that claimed to have the ability of non-coherent detection 2 belong to this category. It is the deterministically enforced relationship on I1 that removes the need of using original signal I0 .

This layer has three key elements, namely, (1) the mechanism for embedding one bit, (2) the perceptual model to ensure imperceptibility, and (3) the modulation/multiplexing techniques for hiding multiples bits. Protocols for achieving additional functionalities are built on top of this “physical layer”, for example, to handle uneven embedding capacity, to enhance robustness and approach capacity via error correction coding, and to CHAPTER 2. 2: Layered structure of a data hiding system. incorporate additional security measures.

TDMA/CDMA-type modulation (right) with total signal energy being fixed at E. The orthogonal modulation and TDMA/CDMA-type modulation can be compared by studying the distance between signal constellation points that represent the secondary data (Fig. 10). Considering the case of conveying B bits using total √ energy E. The minimum distance between signal points is 2E for orthogonal modulation, and is 2 E/B for TDMA/CDMA. When B > 2, orthogonal modulation gives smaller probability of error at a cost of detection complexity.
