Dynamic censuses for the insurance industry On 8 Jul 2009 David Mountain spoke at the Willis Research Network Global Client's meeting about the potential for dynamic censuses to improve risk estimates associated with the movement of people. Traditional censuses and surveys tend to model this behaviour poorly: often people are associated with just one location - their place of residence - which can lead to nave models of risk. Modelling human movement through key locations with no resident population, such as railways stations and stadia, could improve the industrys risk models. David discussed how usage of wireless networks, and photographic imagery, could assist in modelling these complex movement patterns.

giCentre at the Willis Global Clients' meeting Aidan Slingsby presented giCentre research and discussed the role of data visualisation to some of the world's largest insurance and reinsurance companies at the Willis Global Clients meeting in London.

bookScraper: Vocabulary Cluster Graph Our interactive 'clustering' graph has been designed to help compare documents in the bookScraper collection based on the similarity of their vocabularies. The more similar two publications are, the closer they appear to one another in the graph. Groups of books with similar vocabularies cluster.

bookScraper: Vocabulary TreeMap Our interactive treemap allows us to explore the 100 most important words in each of the bookScraper publications. Treemaps are used to show hierarchical information through nested rectangles. The size of each rectangle represents some quantity - numbers of times that words occur in the collection here. Rectangle positions show the relationships between different levels of the hierarchy and their colours relates to numeric values. In this interactive application the hierarchy shows words, within (occurring in) books, within (written by) authors.

bookScraper We have developed two prototype applications with colleagues from The Times to show how interactive visualization of the bookScraper collection may help us identify trends and anomalies in the data set. Doing so may give us ideas about the collection as we aim to explore the data and gain insights from it..
