Traditional graph based sentence ranking approaches modeled the documents as a text graph where vertices represent sentences and edges represent pairwise similarity relationships between two sentences. Such modeling cannot capture complex group relationships shared among multiple sentences which can be useful for sentence ranking. In this paper, we propose two different group relationships (sentence-topic...
In recent years, the popularity of social networking sites proves a lofty raise in their users. Twitter, a micro blogging service less than seven years old, commands more than 500 million users as of July 2012 and is still growing fast. In Twitter, users exchange their ideas through a text based posts called tweets which can have maximum 140 characters. The prevalence and open structure of Twitter...
The internet group-buying has obviously became the most fervent new e-commerce mode in the country in 2010. While the new e-commerce mode has a rapid development, the problems of the internet group-buying have increasingly prominent, it has became a bottleneck of the internet group-buying. In the paper, I have propose some countermeasures to respond the problems in the development of the internet...
This paper describes an NLP-based Chinese ontology construction platform developed by the authors. The construction platform is developed based on the open source project Protégé. The paper mainly focuses on two key technologies of automatic construction of ontology-the extraction of attribute value and the automatic generation of ontology hierarchy structure. The paper then introduces how the automatic...
Bid optimization is now becoming quite popular in sponsored search auctions on the Web. Given a keyword and the maximum willingness to pay of each advertiser interested in the keyword, the bid optimizer generates a profile of bids for the advertisers with the objective of maximizing customer retention without compromising the revenue of the search engine. In this paper, we present a bid optimization...
This paper reports a unique approach to integrate the process planning and scheduling functions. The proposed approach here is used to reduce the tardy jobs by exploring the process plan solution space of the selected jobs. The integrated system comprises a process planning module, a scheduling module and an integrator module. The integration is achieved in an iterative manner. The uniqueness of this...
The objective of this work is to present a methodology for Web-based manufacturing management and control. This methodology is a part of the WebMachining system, which is based on the Electronic-Manufacturing concept. The WebMachining virtual company encompasses three distributed manufacturing systems, all of them located in different cities in Brazil, i.e. Flexible Manufacturing Cell (FMC) at Graco/UnB...
The G-code programming language, introduced in the early 1960psilas, continues to be used to program motions for modern computer numerical controlled (CNC) machines. Vendors augment the motion control commands with various macro languages and other rudimentary programming languages to provide for parametric and flexible CNC programming. More modern programming languages promise greater capability,...
The problem of processing XML streaming data fits a large class of new applications and has been a hot spot recently. The XML streams on the World Wide Web are usually autonomous, distributed and heterogeneity. All existing methods, however, do not support processing a collection of XML streams from heterogeneity data sources. In this paper, we address the heterogeneity issues in the context of XML...
Web-technologies which came up in many fields of automation seem to be a solution which improves device integration in many ways. On the one hand the used Ethernet improves the installation techniques with reliable and approved network cables and routing devices. On the other hand the used internet protocols provide several services for the application software development. The following article is...
The purpose of this paper is to achieve a quantum leap in teleoperation experiments with real devices in laboratory environments. It intends to replace current simulations of networks with time delays - which are usually represented as black boxes (Kamrani, 2005) in software applications such as Matlab or Scilab - with a simple and universal element capable of reflecting, in real time, the state of...
In this paper a face indexing scheme based on spatial similarity is proposed. Spatial scattering of anatomically relevant dominant points on faces is preserved in the kd-tree index structure for efficient retrieval. The methodology is invariant to linear transformation and is robust for pose and expression variations. Experimentation on ORL face database has corroborated the retrieval effectiveness...
Many real-time communication protocols have been studied to guarantee the communication requirements of distributed real-time systems. But, current techniques lack all or most of these requirements specially bounded message delivery time. In this paper we have proposed a Mac layer protocol called RDM+ with concepts similar to Round Data Mailer multi layer protocol. Our simulation results show that...
