A novel method to measure the reliability of the bollywood movie rating system 一种衡量宝莱坞电影评级系统可靠性的新方法
R. Gupta, N. Garg, A. Das
The success of a movie is stochastic but it is no secret that it is dependent to a large extent upon the level of advertisement and also upon the ratings received by the major movie critics. The general audience values their time and money and hence, refers to the leading critics when making a decision about whether to watch a particular movie or not. Due to this, several production houses tends to influence the critics to provide fraudulent ratings in order to increase one's business or decrease other movie's business. In our paper, we have used a methodology called Kappa Measure to analyse the concordance of the Bollywood and Hollywood movie ratings among themselves. Our study proves that there is a statistically significant disagreement between Indian critics, implying that the ratings are biased. The Hollywood ratings showed good agreement and thus, are more reliable. This peculiarity had gone unnoticed so far and no previous studies exist regarding such mismatching patterns in the ratings. Such a result implies that there is a considerable bias among Indian critics and thus, the Indian audiences are not getting the benefit of an impartial critic to guide their judgement. The same methodology was used for Tamil movies (Kollywood) to further investigate the agreement among critics with respect to a regional movie industry. The state of affairs is such that even if a viewer relies on a number of independent critics to form a judgement about a movie's worth, she/he is unlikely to form a clear picture of the movie's actual worth. Our paper shows that the Indian viewers should not rely heavily on movie critics and also that the Bollywood movie rating system is in serious need of an overhaul.
一部电影的成功是随机的,但众所周知,它在很大程度上取决于广告的水平,也取决于主要影评人的评分。普通观众重视他们的时间和金钱,因此,在决定是否观看某一部电影时,他们会参考主要的影评人。因此,一些制作公司倾向于影响评论家提供虚假评级,以增加自己的业务或减少其他电影的业务。在我们的论文中,我们使用了一种叫做Kappa测量的方法来分析宝莱坞和好莱坞电影评级之间的一致性。我们的研究证明印度评论家之间存在统计学上的显著分歧,这意味着评级是有偏见的。好莱坞的收视率表现出良好的一致性,因此更可靠。到目前为止,这种特性一直没有被注意到,以前也没有关于评级中这种不匹配模式的研究。这样的结果意味着印度评论家中存在相当大的偏见,因此,印度观众没有从一个公正的评论家那里得到好处来指导他们的判断。同样的方法被用于泰米尔电影(Kollywood),以进一步调查评论家之间就地区电影工业达成的协议。事态是这样的,即使观众依靠一些独立的评论家来形成对电影价值的判断,她/他也不太可能形成电影实际价值的清晰画面。我们的论文表明,印度观众不应该过分依赖影评人,宝莱坞电影评级系统也急需彻底改革。

Mining conceptual rules for web document using sentence ranking conditional probability 基于句子排序条件概率的web文档概念规则挖掘
V. Navaneethakumar
Text classification and information mining are two significant objectives of natural language processing. Whereas handcrafting rules for both tasks has an extensive convention, learning strategies increased much attention in the past. Existing work presented concept based mining model for text, sentence mining and does not support text classification. To enhance the text clustering approach, we first presented Conceptual Rule Mining On Text clusters to evaluate the more related and influential sentences contributing the document topic. But this model might discriminate terms with semantic variation and negligible authority on the sentence meaning. In addition, we plan to extend conceptual text clustering to web documents, by assigning sentence weights based on conditional probability. Probability ratio is identified for the sentence similarity from which unique sentence meaning contributing to the document topic are listed. In this work, our plan is to implement ranking of the sentences which are calculated using the weights assigned to each and every sentences. With sentence rank conceptual rules are defined for the text cluster documents. The conceptual rule depicts finer tuned document topic and sentence meaning utilized to evaluate the global document contribution. Experiments are conducted with the web documents extracted from the research repositories to evaluate the efficiency of the proposed efficient conceptual rule mining on web document clusters using sentence ranking conditional probability [CRMSRCP] and compared with an existing Model for Concept Based Clustering and Classification and our previous works in terms of Sentence Term Relation, Cluster Object weights, and cluster quality.
文本分类和信息挖掘是自然语言处理的两个重要目标。手工制作这两项任务的规则有着广泛的惯例,而学习策略在过去得到了更多的关注。现有工作提出了基于概念的文本、句子挖掘模型,不支持文本分类。为了增强文本聚类方法,我们首先提出了基于文本聚类的概念规则挖掘,以评估与文档主题相关且更有影响力的句子。但是,该模型可能会对语义变化较大的术语进行区分,而对句子意义的权威可以忽略不计。此外,我们计划通过基于条件概率分配句子权重,将概念文本聚类扩展到web文档。识别句子相似度的概率比,从中列出对文档主题有贡献的唯一句子意义。在这项工作中,我们的计划是使用分配给每个句子的权重来计算句子的排名。通过句子排序,定义了文本聚类文档的概念规则。概念规则描述了用于评估全局文档贡献的更精细的文档主题和句子含义。利用从研究库中提取的web文档进行实验,评估基于句子排序条件概率(CRMSRCP)的web文档聚类高效概念规则挖掘的效率,并在句子术语关系、聚类对象权重和聚类质量方面与现有的基于概念的聚类和分类模型以及我们之前的工作进行比较。

Reversible data hiding technique for stream ciphered and wavelet compressed image 流加密和小波压缩图像的可逆数据隐藏技术
S. Rosaline, C. Rengarajaswamy
Reversible Data Hiding (RDH) Technique aims in recovering back the original content from the marked media. The original image is desirable in some applications. Thus, RDH plays a vital role in such situations. Securing the multimedia content can be achieved by performing encryption. Transmission time is further decreased by compressing such encrypted images. The process of compression reduces the amount of data required for representing the image. The content owner thus encrypts the original image using Stream Cipher process. The encrypted image is then used as the media for hiding secret image. The embedded image can then be compressed using wavelet compression. The receiver does all the three processes in reverse for getting back the original image and the secret image. Thus the compressed image is first decompressed. Second, the data hiding key is employed to extract the secret message. Third, the encryption key is employed to decrypt and get back the original content. Thus this paper focuses on achieving better security and improved transmission rate.
可逆数据隐藏(RDH)技术的目的是从已标记的介质中恢复原始内容。在某些应用中,原始图像是理想的。因此,RDH在这种情况下起着至关重要的作用。保护多媒体内容可以通过执行加密来实现。通过压缩这样的加密图像,传输时间进一步减少。压缩过程减少了表示图像所需的数据量。因此,内容所有者使用流加密过程对原始图像进行加密。然后将加密后的图像用作隐藏秘密图像的介质。然后可以使用小波压缩对嵌入的图像进行压缩。接收方反过来执行这三个过程以获得原始图像和秘密图像。因此,首先对压缩图像进行解压缩。其次,使用数据隐藏密钥提取秘密消息。第三,使用加密密钥解密并获取原始内容。因此,本文的重点是如何实现更好的安全性和更高的传输速率。

网络优化技术在大型网络的框架设计和运行分析中有重要的应用。在通信和计算机网络的随机系统中,服务器崩溃受到越来越多的关注,因为它会对计算机网络的性能和功能产生明显的负面影响,如处理器故障、服务中断、工作优先级和一些外围设备骚乱因素。本文研究了N服务器的多队列网络可能随机发生多种类型的崩溃。源-目的地节点之间可能存在多条路径,这些路径指导通信负载变化、开销或响应时间。每种类型的崩溃都需要在服务变得更智能之前进行有限数量的修复。失效服务器按照前一阶段的顺序进行修复。此外,通信拥塞已成为影响网络用户服务质量的重要问题。随机分解被用来获得队列长度分布的近似。一个特定的随机模型的有用性既取决于它的计算优势,也取决于它能在多大程度上被调整来描述不同的现象。图形化表示了该方法在多服务器崩溃情况下对排队网络性能度量的改进。

A deformable 15D approach for localization and recognition of road traffic monocular images 一种用于道路交通单眼图像定位和识别的可变形15D方法
N. Sankara, T. M. Brughuram
This paper presents a strategic approach for localizing and recognizing the vehicles amidst the traffic scenes generated by monocular camera or video. Previous studies on localization and recognition of vehicles are Model based recognition, 3D triangle based modeling, Model based on Wheel alignment, Ferryman 29D PCA coefficient model and etc. The disadvantages of above listed proposals are Affine transformation issues, redundant Data's, Noise in computation, inability to arrive at accurate shape parameters, poor occlusion detection and too much of modeling's. This paper addresses the above issues and proposes a Deformable Efficient local Gradient based method for localizing the vehicle and Evolutionary Fitness evaluation method with EDA for recognizing exact vehicle model from the traffic scenes. Each images are projected (12D + 3D = 15D) in the image plane. Since the vehicle moves over the ground plane, the pose of the vehicle is determined by position co-efficient X, Y and orientation Θ (3D), the 12 parameters are the parameters of Shape, and it is set up as the prior information based on the mined rules for vehicle localization and continuous EDA approach for vehicle recovery. The system also deals with occlusion of related structures based on stochastic analysis.
本文提出了一种在单目摄像机或视频生成的交通场景中进行车辆定位和识别的策略方法。以往针对车辆定位识别的研究有基于模型的识别、基于三维三角形的建模、基于车轮对中模型、Ferryman 29D PCA系数模型等。上述建议的缺点是仿射变换问题、冗余数据、计算噪声、无法得到准确的形状参数、遮挡检测差以及建模过多。针对上述问题,本文提出了一种基于形变高效局部梯度的车辆定位方法和基于EDA的进化适应度评价方法,用于从交通场景中准确识别车辆模型。每张图像在图像平面上投影(12D + 3D = 15D)。由于车辆在地面上移动,因此车辆的姿态由位置系数X, Y和方向Θ (3D)确定,这12个参数为Shape参数,并根据挖掘的车辆定位规则和连续EDA方法设置为车辆回收的先验信息。该系统还处理了基于随机分析的相关结构遮挡问题。

Since the vehicle moves over the ground plane, the pose of the vehicle is determined by position co-efficient X, Y and orientation Θ (3D), the 12 parameters are the parameters of Shape, and it is set up as the prior information based on the mined rules for vehicle localization and continuous EDA approach for vehicle recovery. The system also deals with occlusion of related structures based on stochastic analysis.","PeriodicalId":123210,"journal":{"name":"2013 International Conference on Pattern Recognition, Informatics and Mobile Engineering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134627523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trust node valuation and path reliability technique for intrusion detection in MANET MANET中入侵检测的信任节点评估和路径可靠性技术
N. Naveen, A. Annalakshmi, K. R. Valluvan
Mobile Ad Hoc Networks rely on each node passively monitor the data forwarding by its next hop. Actually ad hoc network suffers from high false positives. The false positives are reducing network performance (throughput) and increase overhead and inability to mitigate effect of attacks. Trust Node Valuation and Path Reliability technique to thwart intrusion detection against collusion attacks in MANET. Node reputation ranking is made to reduce the false positive detection. This technique is used to enhance monitoring system based IDTs against collusion risk factor. The computation of path reliability considers the number and reputation of nodes for compare both source and retransmitted messages. The main purpose of this technique is work effectively to select the route and promptly detect colluding attacks. Therefore the total number of lost messages decreased and provides more efficient transmissions in ad hoc networks.
移动自组织网络依赖于每个节点被动地监控其下一跳的数据转发。实际上,自组织网络存在高误报。误报降低了网络性能(吞吐量),增加了开销,并且无法减轻攻击的影响。基于信任节点评估和路径可靠性技术的MANET合谋攻击入侵检测。对节点信誉进行排序以减少误报检测。该技术用于增强基于IDTs的系统对合谋风险因素的监控。路径可靠性的计算考虑了节点的数量和信誉,以便对源消息和重传消息进行比较。该技术的主要目的是有效地选择路由并及时检测串通攻击。因此,丢失消息的总数减少了,并在自组织网络中提供了更有效的传输。
