Thus, crime datasets must be interpreted and analyzed in conjunction with various factors that can contribute to the formulation of crime. Discovering these correlations allows a deeper insight into the complex nature of criminal behavior. We introduce a graph based dataset representation that allows us to mine a set of datasets for correlation. We demonstrate our approach with real crime datasets and provide a comparison with other techniques.","PeriodicalId":210911,"journal":{"name":"2009 IEEE International Conference on Intelligence and Security Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124960565","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}

At most times, when a user is reading a news story, she would like to know “what happened before this?“ or “how things progressed after this incident?”. In this paper, we present a novel real-time yet simple method to detect and track new events related to violence and terrorism in news streams through their life over a time line. We do this by first extracting signature of the event, at microscopic level rather than topic or macroscopic level, and then tracking and linking this event with mentions of same event signature in other incoming news articles. There by forming a thread that links all the news articles that describe this specific event, with no training data used or machine learning algorithms employed. We also present our experimental evaluations conducted with Document Understand Conference (DUC) datasets that validate our observations and methodology.","PeriodicalId":210911,"journal":{"name":"2009 IEEE International Conference on Intelligence and Security Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126231950","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}

A key technique for this purpose is whitelisting files, i.e., skipping the detailed analysis of files that match files in a well known reference collection of files. Effective use of this technique requires an efficient method to match files, detecting not only exact matches, but also near matches or approximate matches. This paper outlines the requirements for such matching, formalizes them as the bounded best match and approximate bounded near-match problems, and describes methods to solve these problems. In particular, the approximate bounded near-match problem is mapped to the problem of finding near neighbors in a high-dimensional metric space and solved using locality-sensitive hashing.","PeriodicalId":210911,"journal":{"name":"2009 IEEE International Conference on Intelligence and Security Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116683124","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}

Our experiments are conducted on data collected from LiveJournal. All stability notions aim to locate stable behavior within an individual's area, which is defined in a variety of manners. Our experiments confirm an earlier observation of the highly dynamic nature of the network. Roughly 70% of the communication of a typical week was not observed in the previous week. Depending on the definition of stability and area used, we find small, but highly stable, sets of individuals with stable behavior in the network.","PeriodicalId":210911,"journal":{"name":"2009 IEEE International Conference on Intelligence and Security Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130184133","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}

This in turn enables the terrorists to cause more casualties at their primary target. It is important to efficiently reallocate the available security forces to meet these terrorist attacks, especially when the available resources are limited. In this paper we proposed two game theory-based models for the reallocation of security forces for the purpose of countering both primary and diversionary attacks in an urban environment. The first model is used each target and the “attack on hidden-object game” in which one analyzes the interaction behavior between the security force commander and the terrorists within a zero-sum game. The probability of a primary attack to this target is derived from the mixed strategy Nash equilibrium. The second model uses all these probabilities to compute the Shapley value for each target, in terms of the majority of all probabilities for primary attacks. The Shapley values are then used to create a reallocated set of the limited security forces. Experimental results show the approach proposed in this study is more efficient than the traditional method for dealing with ever more likely gunshot events.","PeriodicalId":210911,"journal":{"name":"2009 IEEE International Conference on Intelligence and Security Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128595007","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}

These personal-journal style blogs expose their authors to potential privacy risks. Bloggers may choose to conceal their identities to mitigate the privacy concerns or disclose their identities for positive relational communication. This study explores the impacts of personal traits and perceived communication context on bloggers' decision of identity disclosure. Data were collected via an online survey of 148 randomly selected bloggers. Results showed that self disclosure tendency and targeting blogs at family and close friends were positive predictors to bloggers' perceived identifiability. In addition, self disclosure tendency and extraversion were found to moderate the relationship between bloggers' perceived vulnerability and identifiability. The implications on privacy management and relational communication online are discussed.","PeriodicalId":210911,"journal":{"name":"2009 IEEE International Conference on Intelligence and Security Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121249405","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}
