Input–output-based measures of systemic importance

Scaling of global inputoutput networks

Examining scaling patterns of networks can help understand how structural features relate to the behavior of the networks. Input–output networks consist of industries as nodes and inter-industrial exchanges of products as links. Previous studies consider limitedmeasures for node strengths and link weights, and also ignore the impact of dataset choice. We consider a comprehensive set of indicato...

Measures of Systemic Risk

A System for Text Summarization Based on Word Importance Measures

This paper presents a text summarization system based on word importance measures. It produces a summary through a part or all of the following four steps. First, we assign local and global scores to the nouns in each sentence according to the functional roles they play and the significancy they assume in the text for summarization. Second, based on the local and global scores, we calculate the...

Generalized moment-independent importance measures based on Minkowski distance

Importance measures have been widely studied and applied in reliability and safety engineering. This paper presents a general formulation of moment-independent importance measures and several commonly discussed importance measures are unified based on Minkowski distance (MD). Moment-independent importance measures can be categorized into three classes of MD importance measures, i.e. probability...

Network reliability importance measures : combinatorics and Monte Carlo based computations

In this paper we focus on computational aspects of network reliability importance measure evaluation. It is a well known fact that most network reliability problems are NP-hard and therefore there is a significant gap between theoretical analysis and the ability to compute different reliability parameters for large or even moderate networks. In this paper we present two very efficient combinato...
