With the rapid growth of the Internet and database technologies in recent years, question answering systems (QAS) have emerged as important applications. Although many QAS have been implemented, little work has been done on the development of a user-centered evaluation for QAS. User-centered evaluation is used to understand a user's needs and identify important dimensions and factors in the development...
The detection of previously unknown, frequently occurring patterns in time series, often called motifs, has been recognized as an important task. To find these motifs, we use an advanced temporal data mining algorithm. Since our algorithm usually finds hundreds of motifs, we need to analyze and access the discovered motifs. For this purpose, we introduce three novel visual analytics methods: (1) motif...
Tagging is a process whereby users freely choose keywords to label Web objects in order to share or recover them later. Tags associated to an object by the user depict his viewpoint or perception. The perception of the target user can be enhanced by aggregating and analyzing the tags associated to an object by other users who share at least one tag with the target user in common for that object and...
This paper analyzes the transmission of a multilevel logic information by assigning a distinct level of Intensity of white light to a specific Byte. The criterion for allocation of Intensities is fed into the programmable transmitter controller. The receiver employs a Photocell to detect the transmitted intensity of white light emitted by an LED. The information at the receiving end is retrieved and...
In this paper, we describe the design of our architecture for continuous, heterogeneous analysis over streams, aka CHAOS that combines stream processing, approximation techniques, mining, complex event processing and visualization. CHAOS, with the novel concept of computational stream analysis Cube, provides an effective, scalable platform for near real time processing of business and enterprise streams...
In this paper, we propose a methodology for real-time characterization of the operational state of a subsystem, device or process in an ecosystem, with the goal of improving its sustainability. The objective is to re-describe the operational state, identified by a set of relevant sensor measurements and other parameters, in terms of known operational patterns. Each pattern is also associated with...
Technology development and implementation process mainly involves; necessitating trends and utility, economic drives & compulsions, host organization working culture & capabilities and competence, awareness & motivation of working technocrats & other professionals. This presentation covers all these main aspects to logically assess the contemporary setup and outline suitable guidelines.
This paper proposed a portable wireless data acquisition system for temperature in real time process dynamics. Process variables (like temperature, pressure, flow, level) vary with time in certain applications and this variation should be recorded so that a control action can take place at a defined set point. This paper proposes an 8 bit embedded platform for a sensor having a network interface using...
