Using big data analysis technologies to cluster user data and mine the potential of stock users is of great significance to telecom operators. In this paper, we present an intelligent swarm clustering algorithm using swarm similarity measure for this purpose. In the proposed scheme, according to the definition of cluster center and the probability distribution of the similarity between objects and...
Personalized search based on the users' preference has been extensively studied in the field of information retrieval. As a typical representative of web2.0, social tagging not only allows users to better describe and manage web resources, but also provides a great opportunity for the personalized search research, since it contains abundant public personal information. In this paper we propose a user...
The concept lattice is an effective tool for data analysis and knowledge extraction. In this paper, the method of extracting classification rules based on concept lattice is studied. According to the characteristics of classification rules, only the nodes with class attribute are generated in the process of constructing concept lattices; thereby the number of lattice nodes has been reduced and the...
There are many algorithms for classification rule based on the FCA; such algorithms usually need to fully establish time-consuming lattice structure. In this article, we propose the extracting algorithms for Frequent Concept Set (FCS), which will not establish the full Formal Concept Lattice. Next, we give an extracting algorithm for classification rule according to the FCS and apply the confidence...
With RFID technology, an item can be conveniently identified by the identifier of the RFID tag attached to it. Some private information of a tag could however be disclosed because a snooper may derive meaningful information from such an identifier and trace the tag's itinerary. To prevent privacy disclosure from tag IDs, we propose to use an active RFID proxy masking device, known as aRPM, to block...
The analysis and the computation to the Luneberg lens center even dielectric sheet and the layered medium ball has been carried on in this article. The most superior coefficient of dielectrical loss variable equation has been obtained. At the same time the relation of N and the relative error has been analyzed, and some results have been got, such as the ideal Luneberg lens coefficient of dielectrical...
Delay-tolerant networks (DTN) have the capacity to interconnect devices in roomy regions unlike traditional networks. Based on common sense, the more similar the mobility pattern of nodes, the more stable their relative positions, which results in a connection between them with a longer duration In this paper, a novel routing scheme using the similarity degree of mobility pattern is proposed to optimize...
Artificial neural network is a nonlinear dynamic system, which can attain the reflection of nonlinear relations among variables within any precision, possessing the ability of solving nonlinear problems, therefore also meeting requirements of economic forecasting. Taking advantages of the nonlinear and dynamic characteristics, by adjusting weights, we can approach any continuous functions by enough...
In order to improve and convey the semantic information perfectly and vividly through synthesized speech, a special prosodic phrasing in broadcasting news programs, namely complex prosodic phrase (C-PP), is proposed in this study. Empirical results show that the C-PP, which there is the pitch declination trend within it, a stable syntactic structure and whole semantic chunk, has a very important role...
Compared with the written word, few experts pay more attention to the spoken word because of the difficulty of obtaining spoken corpora. In order to develop and improve the spoken words research, this paper proposes a novel method for automatic extraction spoken words in broadcasting language, and the result is impressive. From analysis of the result, we extracted 3009 spoken words by the model on...
In order to extract catchwords, new words and other kinds of words for language monitoring, this paper propose the temporal-spatial modeling, which seemed the sort of words as the representation of the different word's distribution in a uniform temporalspatial system. The steady and dynamic features of the different distribution are given. Therefore various kinds of words could be identified and extracted...
Delay-tolerant networks (DTNs) have the capacity to interconnect the devices in roomy regions unlike todaypsilas networks. In this paper, we propose a routing scheme named time interval routing (TIR) to increase deliver ratio and decrease deliver latency in DTNs. TIR, only using limited and local information as well as simple algorithm, chooses the node in transmission range with the least time interval...
Bi0.9Ho0.1FeO3 ceramic is prepared by sol-gel method. We investigated the effect of Ho element doping in the BiFeO3. We studied the microstructure, morphology and ferromagnetism for Bi0.9Ho0.1FeO3 ceramic by XRD, SEM and SQUID. It shows that Bi0.9Ho0.1FeO3 ceramic exhibits single phase of perovskite structure. The c/a rate is elevated from 1 to 1.009 with respect to BiFeO3. The grains of Bi0.9Ho0.1...
