We address the issue of on-line detection of communication problems in spoken dialogue systems. The usefulness is investigated of the sequence of system question types and the word graphs corresponding to the respective user utterances. By applying both ruleinduction and memory-based learning techniques to data obtained with a Dutch train time-table information system, the current paper demonstrates that the aforementioned features indeed lead to a method for problem detection that performs signiﬁcantly above baseline.
We present a new approach to disambiguating syntactically ambiguous words in context, based on Variable Memory Markov (VMM) models. In contrast to fixed-length Markov models, which predict based on fixed-length histories, variable memory Markov models dynamically adapt their history length based on the training data, and hence may use fewer parameters. In a test of a VMM based tagger on the Brown corpus, 95.81% of tokens are correctly classified.
Data compression presents Data in memory have used fixed length for representation, For data transfer (in particular), this method is inefficient; For speed and storage efficiencies, data symbols should use the minimum number of bits possible for representation.
I was born in 1950 in Chelsea, London, but grew up in New Zealand returning to England in 1966. I
have worked in the computer industry since 1975 after a couple of years as a professional drummer.
My first experience was five years as a mainframe hardware engineer for Sperry Univac (now Unisys)
followed by 14 years as an analyst programmer with British Telecom in London.
While engaged in a complex task of converting large quantities of geographical data (map coordinate
references) I discovered the joys of C – its speed and efficiency. That was in 1985 and I have been a
fan of C ever...
Oracle Database 10g, released in 2003 and the current release, enables grid (the g
in 10g) computing. A grid is simply a pool of computers that provides needed
resources for applications on an as-needed basis. The goal is to provide comput-
ing resources that transparently scale to the user community, much as an electri-
cal utility company can deliver power to meet peak demand by accessing energy
from other power providers’ plants via a power grid.
The main purpose of a computer system is to execute programs. These programs, together with the data
they access, must be in main memory (at least partially) during execution.
To improve both the utilization of the CPU and the speed of its response to users, the computer must
keep several processes in memory. Many memory-management schemes exist, reflecting various
Principle of Locality:
Programs access a small proportion of their address space at any time.
Items accessed recently are likely to be accessed again soon,
e.g., instructions in a loop, induction variables.
Items near those accessed recently are likely to be accessed soon,
E.g., sequential instruction access, array data.
With the 4GB Gridfire , you can back up, store, carry and offload large files with one affordable, convenient device. What’s more, means no moving parts, and therefore less chance of damage if the device is dropped. 2 The 2GB One-Tech is the best choice for high-performance results from your digital camera and other handheld devices. 3 The STM gives you the ability to carry your files AND your software on a secure USB drive, by using separate partitions to … 4 The Airlink connects your desktop PC to a network, using the latest advanced silicon chip technology....
The concept of data or information processing arises in a variety of fields. Understanding the principles
behind this concept is fundamental to computer design, communications, manufacturing process control,
biomedical engineering, and an increasingly large number of other areas of technology and science. It is
impossible to imagine modern life without computers for generating, analyzing, and retrieving large
amounts of information, as well as communicating information to end users regardless of their location....
Before you can perform tasks such as adding data and building formulas, you must first start
Excel. This brings the Excel window onto the Windows desktop and you can then begin
using the program. This task and the rest of the book assume that you have already installed
Excel 2010 on your computer.
When you have finished your work with Excel, you should shut down the program. This
reduces clutter on the desktop and in the taskbar, and it also conserves memory and other
New Concepts such as agile modeling, extreme programming, knowledge management, and organizational memory are stimulating new research ideas amoung researchers, and prompting new applications and software. Revolution and evolution are common in the areas of information systemsdevelopment and database. Research Issues in Systems Analysis is a collection of the most up-to-date research-oriented chapters on information systems development and database.

Abstract.The proliferation of new modes of communication and collaboration
has resulted in an explosion of digital information. To turn this challenge into
an opportunity, the IT industry will have to develop novel ways to acquire, store,
process, and deliver information to customers - wherever, however, and whenever
they need it. An ”Intelligent IT Infrastructure,” which can deliver extremely high
performance, adaptability and security - will be the backbone of these develop
Our memory access mechanism provides hardware sup-
port for unprivileged malicious software by allowing ac-
cess to privileged memory regions. Malicious software
triggers the attack by forcing a sequence of bytes on the
data bus to enable the memory access circuits. This se-
quence can be arbitrarily long to avoid false positives
and the particular sequence must be agreed upon be-
Computer main memory comes in two principal varieties: random-access memory or RAM and read-only memory or ROM. RAM can be read and written to anytime the CPU commands it, but ROM is pre-loaded with data and software that never changes, therefore the CPU can only read from it. ROM is typically used to store the computer's initial start-up instructions. In general, the contents of RAM are erased when the power to the computer is turned off, but ROM retains its data indefinitely. In a PC, the ROM contains a specialized program called the BIOS that orchestrates loading the computer's operating...
