Advancement in information technology is playing an increasing role in the use of information systems comprising relational databases. These databases are used effectively in collaborative environments for information extraction consequently, they are vulnerable to security threats concerning ownership rights and data tampering. Watermarking is advocated to enforce ownership rights over shared relational data and for providing a means for tackling data tampering. When ownership rights are enforced using watermarking, the underlying data undergoes certain modifications as a result of which, the data quality gets compromised. Reversible watermarking is employed to ensure data quality along with data recovery. However, such techniques are usually not robust against malicious attacks and do not provide any mechanism to selectively watermark a particular attribute by taking into account its role in knowledge discovery. Therefore, reversible watermarking is required that ensures i watermark encoding and decoding by accounting for the role of all the features in knowledge discovery and, ii original data recovery in the presence of active malicious attacks. In this paper, a robust and semi blind reversible watermarking RRW technique for numerical relational data has been proposed that addresses the above objectives. Experimental studies prove the effectiveness of RRW against malicious attacks and show that the proposed technique outperforms existing ones. Wlan Mimo Channel Matlab ProgramsPolarity Consistency Checking for Domain Independent Sentiment Dictionaries. Polarity classification of words is important for applications such as Opinion Mining and Sentiment Analysis. A number of sentiment wordsense dictionaries have been manually or semiautomatically constructed. We notice that these sentiment dictionaries have numerous inaccuracies. Besides obvious instances, where the same word appears with different polarities in different dictionaries, the dictionaries exhibit complex cases of polarity inconsistency, which cannot be detected by mere manual inspection. We introduce the concept of polarity consistency of wordssenses in sentiment dictionaries in this paper. We show that the consistency problem is NP complete. We reduce the polarity consistency problem to the satisfiability problem and utilize two fast SAT solvers to detect inconsistencies in a sentiment dictionary. We perform experiments on five sentiment dictionaries and Word. Net to show inter and intra dictionaries inconsistencies. Co Extracting Opinion Targets and Opinion Words from Online Reviews Based on the Word Alignment Model. Mining opinion targets and opinion words from online reviews are important tasks for fine grained opinion mining, the key component of which involves detecting opinion relations among words. To this end, this paper proposes a novel approach based on the partially supervised alignment model, which regards identifying opinion relations as an alignment process.

Finally, candidates with higher confidence are extracted as opinion targets or opinion words. Compared to previous methods based on the nearest neighbor rules, our model captures opinion relations more precisely, especially for long span relations. Compared to syntax based methods, our word alignment model effectively alleviates the negative effects of parsing errors when dealing with informal online texts. Cbeebies Balamory Inventor Game more. In particular, compared to the traditional unsupervised alignment model, the proposed model obtains better precision because of the usage of partial supervision. In addition, when estimating candidate confidence, we penalize higher degree vertices in our graph based co ranking algorithm to decrease the probability of error generation. Our experimental results on three corpora with different sizes and languages show that our approach effectively outperforms state of the art methods. Tweet Segmentation and Its Application to Named Entity Recognition. Twitter has attracted millions of users to share and disseminate most up to date information, resulting in large volumes of data produced everyday. However, many applications in Information Retrieval IR and Natural Language Processing NLP suffer severely from the noisy and short nature of tweets. In this paper, we propose a novel framework for tweet segmentation in a batch mode, called Hybrid. Seg. By splitting tweets into meaningful segments, the semantic or context information is well preserved and easily extracted by the downstream applications. Hybrid. Seg finds the optimal segmentation of a tweet by maximizing the sum of the stickiness scores of its candidate segments.

For the latter, we propose and evaluate two models to derive local context by considering the linguistic features and term dependency in a batch of tweets, respectively. Hybrid. Seg is also designed to iteratively learn from confident segments as pseudo feedback. Experiments on two tweet data sets show that tweet segmentation quality is significantly improved by learning both global and local contexts compared with using global context alone. Through analysis and comparison, we show that local linguistic features are more reliable for learning local con text compared with term dependency. As an application, we show that high accuracy is achieved in named entity recognition by applying segment based part of speech POS tagging. Entity Linking with a Knowledge Base Issues, Techniques, and Solutions. The large number of potential applications from bridging web data with knowledge bases has led to an increase in the entity linking research. Entity linking is the task to link entity mentions in text with their corresponding entities in a knowledge base. Potential applications include information extraction, information retrieval, and knowledge base population. However, this task is challenging due to name variations and entity ambiguity. In this survey, we present a thorough overview and analysis of the main approaches to entity linking, and discuss various applications, the evaluation of entity linking systems, and future directions. Customizable Point of Interest Queries in Road Networks. We present a unified framework for dealing with exact point of interest POI queries in dynamic continental road networks within interactive applications. We show that partition based algorithms developed for point to point shortest path computations can be naturally extended to handle augmented queries such as finding the closest restaurant or the best post office to stop on the way home, always ranking POIs according to a user defined cost function. Our solution allows different trade offs between indexing effort time and space and query time. Our most flexible variant allows the road network to change frequently to account for traffic information or personalized cost functions and the set of POIs to be specified at query time. Even in this fully dynamic scenario, our solution is fast enough for interactive applications on continental road networks. Context Based Diversification for Keyword Queries Over XML Data.
