Detailing physical security requirements and controls, this updated edition offers a sample physical security policy and includes a complete list of tasks and objectives that make up an effective information protection program.
This best-selling, easy to read book offers the most complete discussion on the theories and principles behind today's most advanced communications systems. Throughout, Haykin emphasizes the statistical underpinnings of communication theory in a complete and detailed manner. Readers are guided though topics ranging from pulse modulation and passband digital transmission to random processes and error-control coding. The fifth edition has also been revised to include an extensive treatment of digital communications....
During the past 25 years of digital information development, industry-wide discussion has progressed from resolving technology issues for managing GI to establishing policy for accessing it, especially in the public sector. Geographic Information: Value, Pricing, Production and Consumption brings the producer and consumer arguments together, providing a fresh perspective on the emotional and territorial issues of IPR (intellectual property rights) protection and liberation.
Information Theory, Evolution, and the Origin of Life presents a timely
introduction to the use of information theory and coding theory in molecular
biology. The genetical information system, because it is linear and digital,
resembles the algorithmic language of computers. George Gamow pointed
out that the application of Shannon’s information theory breaks genetics and
molecular biology out of the descriptive mode into the quantitative mode,
and Dr. Yockey develops this theme, discussing how information theory and
coding theory can be applied to molecular biology....
This paper discusses research on distinguishing word meanings in the context of information retrieval systems. We conducted experiments with three sources of evidence for making these distinctions: morphology, part-of-speech, and phrases. We have focused on the distinction between h o m o n y m y and polysemy (unrelated vs. related meanings). Our results support the need to distinguish h o m o n y m y and p o l y semy. We found: 1) grouping morphological variants makes a significant improvement in retrieval performance, 2) that more than half of all words in a dictionary that differ...
Microsoft Official Curriculum (MOC), available to IT Academies at a discounted price, is professional courseware intended for IT professionals and developers who build, support, and implement solutions by using Microsoft products and technologies. MOC is designed to cover the topics that employers know are mission-critical in the real world.In this activity, you will participate in a class discussion to identify the value of
modeling as a way of analyzing information.
This occasional paper proposes the development of an information framework for sustainable development in South Africa and sets out a global action plan. It discusses the country's ability to provide the information required to address actions stipulated in Agenda 21, a foundational document of sustainable development.
Each year, typically in the summer, the Board on Atmospheric Sciences and
Climate selects a topic for special study (often called our “summer study”). Our
goal is to organize an informal workshop where scientists and agency staff can
share information about current issues in the atmospheric sciences, meteorology,
and climate. These events are a forum for frank discussions and creative inter-
action, and sometimes lead us to develop more in-depth activities.
This paper examines the feasibility of using statistical methods to train a part-of-speech predictor for unknown words. By using statistical methods, without incorporating hand-crafted linguistic information, the predictor could be used with any language for which there is a large tagged training corpus. Encouraging results have been obtained by testing the predictor on unknown words from the Brown corpus. The relative value of information sources such as affixes and context is discussed.
After you read this chapter you should be able to: Discuss the importance of project management, feasibility assessment, documentation, and data and information gathering techniques; discuss the purpose of each system development phase; differentiate between lowlevel languages and procedural languages;...
Chinese characters that are similar in their pronunciations or in their internal structures are useful for computer-assisted language learning and for psycholinguistic studies. Although it is possible for us to employ imagebased methods to identify visually similar characters, the resulting computational costs can be very high. We propose methods for identifying visually similar Chinese characters by adopting and extending the basic concepts of a proven Chinese input method--Cangjie. We present the methods, illustrate how they work, and discuss their weakness in this paper. ...
The paper describes an interface between generator and synthesizer of the German language concept-to-speech system VieCtoS. It discusses phenomena in German intonation that depend on the interaction between grammatical dependencies (projection of information structure into syntax) and prosodic context (performancerelated modifications to intonation patterns). Phonological processing in our system comprises segmental as well as suprasegmental dimensions such as syllabification, modification of word stress positions, and a symbolic encoding of intonation. ...
We discuss a seml-interactive approach to information retrieval which consists of two tasks performed in a sequence. First, the system assists the searcher in building a comprehensive statement of information need, using automatically generated topical summaries of sample documents.
Model-theoretic semantics provides a computationally attractive means of representing the semantics of natural language. However, the models used in this formalism are static and are usually infinite. Dynamic models are incomplete models that include only the information needed for an application and to which information can be added. Dynamic models are basically approximations of larger conventional models, but differ is several interesting ways. The difference discussed here is the possibility of inconsistent information being included in the model. ...
We will describe an Earley-type parser for Tree Adjoining Grammars (TAGs). Although a CKYtype parser for TAGs has been developed earlier (Vijay-Shanker and :Icshi, 1985), this is the first practical parser for TAGs because as is well known for CFGs, the average behavior of Earley-type parsers is superior to that of CKY-type parsers. The core of the algorithm is described. Then we discuss modifications of the parsing algorithm that can parse extensions of TAGs such as constraints on adjunction, substitution, and feature structures for TAGs.
Topological Dependency Grammar (TDG) is a lexicalized dependency grammar formalism, able to model languages with a relatively free word order. In such languages, word order variation often has an important function: the realization of information structure. The paper discusses how to integrate information structure into TDG, and presents a constraint-based approach to modelling information structure and the various means to realize it, focusing on (possibly simultaneous use of) word order and tune. ...
