Sharing data provides great benefit to the research community. But disclosing identifiable, sensitive information such as medical records can cause irreparable damage. A number of methods have been proposed to anon Mize sensitive information. With some approaches, term relationships in the data may help to re-identify the original data given the de-identified data. This papers studies the significance of correlation in data and then analyzes the effect on anonymization techniques including t-plausibility and k-manonymity. Finally, we show how to address correlation in thet-plausibility model.

In this paper, we propose a semantic negotiation based service framework for the extraction of optimized service information without user intervention in intelligent Machine to Machine (M2M) environment. Proposed semantic negotiation procedure is used for a machine in order to interact with another encountered heterogeneous machine. Through the proposed semantic negotiation procedure, each machine can understand the messages thoroughly sent by the corresponding machine and exchange necessary information.

The Machine-to-Machine (M2M) paradigm involves devices (sensors, actuators) interacting together to provide services located in the real world. The Senscity project proposes an infrastructure to enable shared city scale applications -- ie. smart cities. Implementing such an infrastructure raises the problem of providing an agile governance with respect to scalability. Multi-Agent technologies grant adaptability, flexibility and proactivity properties. This paper investigates how they can suit to our problem. It proposes a Multi-Agent organization for expressing the governance strategy of such systems. Using the MOISE Organization framework, it is illustrated within a smart parking management application.

Outline social media networks (OSMNs) such as Twitter provide great opportunities for public engagement and event information dissemination. Event-related discussions occur in real time and at the worldwide scale. However, these discussions are in the form of short, unstructured messages and dynamically woven into daily chats and status updates. Compared with traditional news articles, the rich and diverse user-generated content raises unique new challenges for tracking and analyzing events. Effective and efficient event modeling is thus essential for real-time information-intensive OSMNs. In this work, we propose ETree, an effective and efficient event modeling solution for social media network sites. Targeting the unique challenges of this problem, ETree consists of three key components: (1) an n-gram based content analysis technique for identifying core information blocks from a large number of short messages, (2) an incremental and hierarchical modeling technique for identifying and constructing event theme structures at different granularities, and (3) an enhanced temporal analysis technique for identifying inherent causalities between information blocks. Detailed evaluation using 3.5 million tweets over a 5-month period demonstrates that ETree can efficiently generate high-quality event structures and identify inherent causal relationships with high accuracy.

Agent-oriented methodologies emphasize organisational concepts, which give structure to large agent systems. Organisational frameworks, however, put an extra burden on developers, who need to master both an agent-oriented programming language and the framework itself. We believe that the organisation of agent systems should be directly supported by features of the programming language. In this paper we propose three such language features: algebraic data types, roles, and sessions. They are inspired by functional programming languages and by session types. How they fit together in the context of agent-oriented programming is new.

This work introduces Energy City, a multi-agent framework designed and developed in order to simulate the power system and explore the potential of Consumer Social Networks (CSNs) as a means to promote demand-side response and raise social awareness towards energy consumption. The power system with all its involved actors (Consumers, Producers, Electricity Suppliers, Transmission and Distribution Operators) and their requirements are modeled. The semantic infrastructure for the formation and analysis of electricity CSNs is discussed, and the basic consumer attributes and CSN functionality are identified. Authors argue that the formation of such CSNs is expected to increase the electricity consumer market power by enabling them to act in a collective way.

During events that involve large crowds (e.g., demonstrations or sports events), large-scale aggressive outbursts are not uncommon. Since these outbursts are usually triggered by relatively small stimuli, and the amount of people involved may grow very quickly, their emergence is often highly unpredictable and difficult to control. The number of different factors that play a role in the development of crowds is large, which makes it difficult to gain a concrete insight in how the collective aggressive behaviour of a given crowd (with known parameters) will develop. This paper is a position paper and is to be considered as a first step in the development of an ambient system to analyse and control the emergence of aggressive behaviour in crowds under different circumstances. The main purpose is to use the system to provide support for police officers and (formal) guardians in both detecting, decreasing and avoiding (the number of) riots.

Planning with Answer Set Programming (ASP) has been described as a valuable approach to express planning problems in a declarative way. However, few publications addressed the modeling of Blackboard system with answer set programming. In this paper, we study the advantages of using an action language and ASP to develop a Blackboard system. We conclude our article by describing our Blackboard system and we show the usefulness of the extended Akc language to control and plan the agents' actions.

We pose a new problem of discovering associations between events in our daily lives and their characteristic items, such as (Halloween, pumpkin) and (Christmas, chimney). To solve the problem, we dopted an approach similar to that of existing research on event detection, which tries to discover events by detecting bursts of occurrence frequency of a relevant term in a document stream, where the term (item) is associated with the discovered event. We extracted events from blog entries available on the Web, while the previous studies mostly used news articles as document streams. Blog entries are shown to have quite different characteristics to news articles. Considering this fact, we developed a method for discovering the associations by integrating existing techniques that can handle and take advantage of the characteristics of blog data. We verified through experiments using actual data that the proposed approach works quite well.
