Many scientific experiments are designed as computational workflows in the bioinformatics domain, which facilitates implementation and analysis. However, the amount of data generated increases at every phase of each execution, hindering the identification of the source and the data transformation. Therefore, it has become necessary to create new tools to verify automatically which resources and parameters...
We are interested in using purely network-based techniques to assist in matching instances across databases that can be represented as complex networks. In particular we are interested in the individuality of the influence neighbourhood of a node (the sub graph induced by its in-neighbours) in a directed network. We derive a paper citation network from the archived Cite Seer database and use this...
New generation of future power system control centers need a paradigm shift in their utility IT operations, coordinated use of applications and the architectural designs to meet new challenges. However, literature on comprehensive architectural design and implementation towards this direction is scarce. In this paper, an architecture design and implementation aspects are demonstrated for integrating...
Based on the real situation of radio telegraphic training and using the net classroom, this paper proposes a design of radio telegraphic training and an assessment system which adopts C/S mode. It conducts careful analysis on various key technologies, such as manual key keying signal processing, MORSE code store-and-forward and intersystem data interaction, and put forwards corresponding solutions...
In a Cloud environment, an independent service or model referred to as object storage is used for the management of persistent data. This model provides a virtualized pool of storage resources and can be accessed via Application Programming Interface (API) and/or simply a browser. Object storage is used to store the persistent data from various users through put/get methods and it also store the virtual...
The ATLAS experiment at the LHC (CERN) comprises a large and geographically distributed community of about three thousand scientists from all over the world. A shift crew of about 10 people running the experiment 24/7 supervises the data taking. Information concerning the experiment operation and behavior has to be reported and shared with the whole community. To provide such functionality, a logbook...
In this paper, we propose an approach to retrieval XML data with structural context relaxation. We process user query and XML documents as structural term set. Context resemblance is computed based on level weight of element in context, level similarity between elements in longest matched subsequence and other factors. We extend Vector Space Model to answer XML content and structure search. Experiments...
In this paper a public database for writer retrieval, writer identification and word spotting is presented. The CVL-Database consists of 7 different handwritten texts (1 German and 6 English Texts) and 311 different writers. For each text an RGB color image (300 dpi) comprising the handwritten text and the printed text sample are available as well as a cropped version (only handwritten). A unique...
Technical evolution has been improved day-by-day in web services. Service provider has provided several monumental changes to fulfill the requirement of service requester. Generally these services are provided through functional and non-functional Quality of Service (QoS). Most of these models lack unique factors like selection, ranking and other QoS parameters. The proposed system describes the Web...
Recently, the mapping from Relational Databases (RDB) into Resource Description Framework (RDF) becomes an essential demand for most of the people who are consuming the Web in their daily activities and businesses due to the need for getting complete integrated, trustworthy and understandable data that achieving their requirements and wishes. However, management and controlling the RDB-RDF mapping...
Today a huge amount of geospatial data is being created, collected and used more than ever before. The ever increasing observations and measurements of geo-sensor networks, satellite imageries, point clouds from laser scanning, geospatial data of Location Based Services (LBS) and location-based social networks has become a serious challenge for data management and analysis systems. Traditionally,...
Interactive Voice Response (IVR) systems can handle up to 60% of the incoming calls in the call center. Since it promotes self-serving and decreases the number of the agents in the call center, it may lead to improved customer and call center agent satisfaction, increased revenue, and reduced cost. One bottleneck of IVR is that; dynamic nature of services provided by the companies and the needs of...
This paper discusses Extensible Messaging and Presence Protocol (XMPP) based promising applications and their prospective use in military and defense industry. XMPP, being an Extensible Markup Language (XML) based protocol, is a widely preferred and open-standard Instant Messaging (IM) protocol. Although many XMPP based systems are readily available in non-military markets it is believed that subject...
Queries against the large size XML database are often exploratory and users often find their queries return too many answers, this paper proposed a user preference-based top-k ranking approach to deal with this “information overload” problem. We first presented a user preference model which can embody both the partial relations and the interest degree of preferences. And then, the elements orders...
Step-by-step and from-easy-to-difficult are the outstanding characteristics of geological interpretationof remote sensing images. The interpretation results, especially the attributes of interpreted features, can be changed or adjusted on each step according to the reference materials and the field work feedback. As aconsequence, geological interpreters may make a lot of attribute adjustments and...
Preserving data quality is an important issue in data collection management. One of the crucial issues hereby is the detection of duplicate objects (called coreferent objects) which describe the same entity, but in different ways. In this paper we present a method for detecting coreferent objects in metadata, in particular in XML schemas. Our approach consists in comparing the paths from a root element...
There have been various bug tracking systems for software development. However, it's difficult to obtain useful information from those systems since they are composed of web pages. In this paper, we propose two ways of extracting raw data by parsing the bug report pages and refining them. Our future work is to categorize bugs and interesting patterns automatically by analyzing the extracted data from...
Data preprocessing plays an essential role in the process of safety equipment linkage system, directly influenced the quality and the results of the later analysis and decision-making. This paper describes the process of data preprocessing in detail, and according to the characteristics of the linkage system data, proposes an improved data cleaning method in order to improve the efficiency of data...
We proposed the WFSTDM which is an expandable and adaptable dialogue management platform. The WFSTDM combines various WFSTs and enables us to develop new dialogue management WFSTs necessary for rapid prototyping of spoken dialogue systems. In this paper, we illustrate the outline of the WFSTDM and introduce the WFSTDM builder, a network-based spoken dialogue system development tool. In addition, we...
Traditional education systems are highly theoretical and almost entirely based on student knowledge memorization. Nowadays european society development is focused on practical skills, globalization and competitiveness. Existing romanian e-learning systems tend to present and explain knowledge in a spectacular way using multimedia but none of them are based on the concept of competence. The solution...
