After analyzing several practical aspects of relevant data gathering under disaster circumstances, realistic requirements for the search for data under disaster conditions are determined and an optimized algorithm is proposed for the search and collection of data on SNs satisfying the requirements. A system built for performing the search is presented and search results are illustrated and discussed...
We study statistical issues related to the use of words in messages on SNs, as related to specific potentially catastrophic events, such as fires and earthquakes. The analysis investigates the frequency of the words in the messages of interest, moreover their temporal correlation, and aims to determine a reasonable number of keywords for the searches of the events, especially in relation with analytics...
We aim to contribute clarifying the concept of resilience and to introduce issues related to resilience computation. The contributions of this paper include interpretations of the resilience as a couple of largely dichotomic processes, the definition of several concepts related to resilience, the derivation of a set of properties of a resilience index previously introduced, an incipient study of the...
