With the rapid development of the Internet, massive Internet text data has brought new opportunities and challenges to the research of entity relation extraction. Open entity relation extraction overcomes the shortage of traditional methods, that relation types need to be predefined and plenty of training data need to be labeled in advance. A lot of work have been done for English Open ERE, and now...
With the popularity of the Internet, online news media are pouring numerous of news reports into the Internet every day. People get lost in the information explosion. Although the existing methods are able to extract news reports according to key words, and aggregate news reports into stories or events, they just list the related reports or events in order. Moreover, they are unable to provide the...
This paper proposes a dynamic channel utilization method to minimize transmission delay by considering radio interference and wireless link rate for software defined multi-channel wireless mesh networks (SD-WMN). The OpenFlow technology, which enables us to control flows by programming, is employed to effectively utilize multiple channels in SD-WMN for traffic balancing. Existing methods assume fixed...
Characteristics of flow describe the pattern and trend of network traffic, it helps network operator understanding network usage and user behavior, especially useful for those who concerns more about network capacity planning, traffic engineering and fault handling. Due to the large scale of datacenter network and explosive growth of traffic volume, it's hard to collect, store and analyze Internet...
In services based applications, many inevitable factors, such as network fault, host exception, etc., will lead to the frequent failure of some component services. This paper presents a two phases approach for recovery of services based applications. The proposed approach can recover a services based application to provide both consistent function and consistent QoS by replacing its individual or...
The connected component of an undirected graph plays an important part in graph theory. It is straightforward to compute the connected components of a graph in linear time using either breadth-first search or depth-first search. However when confronted with large scale data, both of the two algorithms are hard to execute. In this paper, we introduce a recently proposed community detection technique...
We study the problem of automatically extracting semantic information network and social network from the online forum. We describe an efficient system called INEOF which is capable of processing millions of forum posts in a few hours. We also introduce some applications, including topic detection and opinion leader detection based on social network analysis techniques after building the two type...
Along with informationization advancement thorough and Internet rapid development, there exists millions of websites on the Internet. Search engines become a mediator to connect web users and websites. The query logs in which recorded daily contains a wealth of knowledge about the actions of the users of search engines, and as such they contain valuable information about the interests, the preferences,...
Recently, a growing number of researches have focused on the issues raised by the knowledge discovery of online information, particularly the problems of tracking topics, ideas, and users' spreading influence across the Web. In this paper, the search-engine query logs on Topic Detection and Tracking (TDT) is analyzed other than study of the quality of the search result or query recommendation. By...
The reforms of the agricultural irrigation management become the important content of the construction of the conservation-minded society and new socialist countryside, however, the traditional management of client/server mode can't meet the requirements. Consequently, the optimization of the irrigation management is inevitable according to the development of the irrigation facilities and the complication...
Security is an important aspect in Web development, and the access control and authorization is the key problem in Web security. The core idea of role-based access control (RBAC) is to implement safe access of data by allocating proper roles to the users to indirectly connect users with access permissions. RBAC is introduced to the geological system permission management by classifying and arranging...
With the rapid development of Information Technology such as Web 2.0, the internet is getting more interactive which supplying more information of individuals and social community composed of individuals for market analysis in enterprises. A new Social CRM Tool framework based on complex network analysis technologies aiming to offer better marketing and sale results for Mobile BOSS (Business Operation...
Network value has attracted more and more attentions from scholars and enterprisers. Information through network can essentially impact everyone, while everyone in the network has the structure function to the network and may also influence others. But the contribution to the network is not the same for every one. Based on the complex network theory and customer activity, a customer network value...
Virtual Home Library (VHL) is an integrated IT system that utilizes virtual reality technology and an IPTV set-top box (STB) to virtually construct a 'library' and the relevant reading environment on televisions in people's home. Unlike the online e-book reading applications, Virtual Home Library system can be applied on televisions - the world's most convenient and most efficient communication tool...
In this paper, an Internet-based controller is designed based on synchronizing clock of the remote controller computer with that of the local computer. An observer-based state feedback control strategy is proposed. Asymptotic stability of the closed-loop system is achieved without the assumption of reliable transmission from the controller computer to the local computer, which reduces the requirement...
