Mining Events from Multimedia streams, Jon Hare

peaker(s): Jon Hare Organiser: Time: 25/06/2014 11:00-11:50 Location: B32/3077 Abstract The aggregation of items from social media streams, such as Flickr photos and Twitter tweets, into meaningful groups can help users contextualise and effectively consume the torrents of information on the social web. This task is challenging due to the scale of the streams and the inherently multimodal nature of the information being contextualised. In this talk I'll describe some of our recent work on trend and event detection in multimedia data streams. We focus on scalable streaming algorithms that can be applied to multimedia data streams from the web and the social web. The talk will cover two particular aspects of our work: mining Twitter for trending images by detecting near duplicates; and detecting social events in multimedia data with streaming clustering algorithms. I'll will describe in detail our techniques, and explore open questions and areas of potential future work, in both these tasks.

Scalable real-time crisis mapping and analytics of social media streams for disaster management and breaking news

Real-time geoparsing of social media streams (e.g. Twitter, YouTube, Instagram, Flickr, FourSquare) is providing a new 'virtual sensor' capability to end users such as emergency response agencies (e.g. Tsunami early warning centres, Civil protection authorities) and news agencies (e.g. Deutsche Welle, BBC News). Challenges in this area include scaling up natural language processing (NLP) and information retrieval (IR) approaches to handle real-time traffic volumes, reducing false positives, creating real-time infographic displays useful for effective decision support and providing support for trust and credibility analysis using geosemantics. I will present in this seminar on-going work by the IT Innovation Centre over the last 4 years (TRIDEC and REVEAL FP7 projects) in building such systems, and highlights our research towards improving trustworthy and credible of crisis map displays and real-time analytics for trending topics and influential social networks during major news worthy events.

El uso en las organizaciones de venta al por mayor del marketing mediante la relación estratégica comunitaria y efectividad de la misma

Se busca ver cuál es el uso que las organizaciones hacen del concepto y estrategias comunitarias mediante el marketing; aunque existen varias formas de fidelizar el cliente, en el sector de comercio al por mayor, se vio una gran dificultad de acercarse al consumidor. Una de las formas más fáciles y efectivas de hacerlo es por medio de comunidades ya que elimina las barreras de mercado y crea vínculos entre cliente-empresa. Para esto se utilizó el análisis de caso, seleccionando una organización de relevancia en el sector de venta al por mayor. En dicha organización no se encontró el uso de la relación estratégica comunitaria de forma directa, aunque se vio un interés en incorporarlo; esto se evaluó mediante fuentes de evidencia, tales como entrevistas, informes financieros de la compañía, documentos que proporciono la organizaciones, pagina web e información del comercio de venta al por mayor y fundamentación teórica para realizar un óptimo análisis. A la empresa se le recomienda incorporar en sus planes estratégicos la relación estratégica comunitaria; esto ayudaría a eliminar barreras de mercado, identificar las necesidades o nuevos nichos de mercado.

Networks and RegionalCompetitiveness: Towards a Transaction Cost Approach of Small-Scale Cooperation

A preoccupation with competition often dominates the study of governance. A focus on competition often unnecessarily precludes the possibility that regional institutions can suspend competition in certain areas and facilitate cooperation among potential rivals, thereby potentially contributing to their mutual success. In many ways companies cooperating through these types of networks have a greater degree of flexibility than firms which are forced to rely solely on hierarchies or markets for solutions to their problems. In order to fully understand how such networks work, this article first parses out differences in definitions of networks in order to understand how the type of network mentioned above actually differs from other uses of this term. Then it develops a theory of governance that goes beyond hierarchies and markets by demonstrating how this type of network can lead to reductions in transaction costs. This claim is illustrated on hand from examples of alternative forms of organization in Germany and Italy.

The Intrapreneur Innovation:Led by Medium and Small Size Companies‘Managers*(Qualitative Research)

This research is focused on an exploratory study developed with Pymes managers and theirroles as intrapreneurs. Using their leadership to impel innovation into organizations.Looking to determined how Pymes employers incentive into organizations individuals or groupinnovations. Therefore, it is possible to think that managers lead the innovation process, whichis classified gradually according to companies needs in order to improve their competitiveness.Organization must have intrapreneuring and organized culture with flexible structure to generateindividual autonomy. A characteristic is the amount of capital risk needed; that is why it isnecessary encourage their work and their risk tolerance.

Lethal Closeness: The Evolution of a Small-World Drug Trafficking Network

The evolution of the drug trafficking network –so-called– ‘Cartel del Norte del Valle’, is studied using network analysis methods. We found that the average length between any pair of its members was bounded by 4 –an attribute of smallworld networks. In this tightly connected network, informational shocks induce fear and the unleashing of searches of threatening nodes, using available paths. Lethal violence ensues in clusters of increasing sizes that fragment the network, without compromising, however, the survival of the largest component, which proved to be resilient to massive violence. In spite of a success from the point of view of head counting, the US’ socialization program for drug traffickers did not effectively change the cyclical dynamics of the drug dealing business: war survivors took over what was left from the old network initiating a new cycle of business and violence.

Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

Una historia sobre una foca huérfana y su lucha por la supervivencia. En la segunda parte del libro, los niños aprenderán sobre las focas huérfanas en la vida real y descubrir la forma en que aumentan las probabilidades de sobrevivir con la ayuda de las personas que cuidan de ellas.

The world of the cell : life on a small scale.

Este título pertenece a una serie que ofrece en profundidad una visión de las células en todo el mundo vivo, su estructura y los procesos en que se basa la vida en la Tierra. Examina cómo se unen las células y cómo mantienen la vida mediante el control de una compleja serie de reacciones químicas. En él se muestran las diferencias entre los dos tipos de células: las procariotas (bacterias y arqueas) y los eucariotas (todas las demás). Cómo en las primeras formas de vida las células fueron probablemente muy similares a algunas bacterias de hoy en día. La nueva clasificación del reino arqueas también puede ofrecer pistas sobre el origen de la vida en la Tierra. Tiene un cuadro sumario de bioquímica imprescindible para el origen de la vida, glosario, referencias bibliográficas e índice.
