Interaction between consumers and companies can create conflict. When a consensus is unreachable there are legal authorities to resolve the case. This letter is a study of data from the Brazilian Department of Justice from which we build a bipartite network of categories of complaints linked to the companies receiving those complaints. We find the complaint categories organised in an hierarchical way where companies only get complaints of lower degree if they already got complaints of higher…

Metrics of Emergence, Self-Organization, and Complexity for EWOM Research
TLDR
It is argued possible pragmatic ways to understanding the valuable information present in word-of-mouth data found on electronic commerce platforms are argued.
Social physics
TLDR
The future for social physics is bright, by comprehensively (but not exhaustively) reviewing the current state of the art of physics-inspired and physics-like work on societal problems, and paying respect to intellectual mavericks who nurtured the field to its maturity.
Anatomy of Scientific Evolution
TLDR
This work investigates scientific evolution through systematic analysis of a massive corpus of digitized English texts between 1800 and 2008, revealing great predictability for long-prevailing scientific concepts based on the levels of their prior usage and indicating that slowly-but-commonly adopted science and technology surprisingly tend to have higher innate strength than fast-and-commoned ones.
Exploring patterns of empirical networks
We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior

An analysis of online customer complaints: implications for Web complaint management
TLDR
The research findings suggest that e-businesses should provide excellent online customer services because customer service is the most important factor in online customer satisfaction; respond to customers' requests/complaints quickly because the response speed is more important in onlineCustomer satisfaction than offline.
Empirical analysis of web-based user-object bipartite networks
TLDR
This letter reports the empirical analysis on two large-scale web sites, audioscrobbler.com and del.icio.us, and proposes a new index, named collaborative similarity, to quantify the diversity of tastes based on the collaborative selection.
Trees = Networks ?!?
TLDR
The network-tree mapping described in this work provides a simple and yet effective means of community detection and underlies several key concepts and issues of current interest in complex networks, including comprehensive characterization of trees and community detection.
Spanning Trees and bootstrap Reliability Estimation in Correlation-Based Networks
TLDR
It is shown that the Average Linkage Minimum Spanning Tree recognizes economic sectors and sub-sectors as communities in the network slightly better than the Minimumspanning Tree and the average reliability of links is slightly greater than the average unreliable links in the average linkage minimum Spanning tree.
Network flows - theory, algorithms and applications
TLDR
In-depth, self-contained treatments of shortest path, maximum flow, and minimum cost flow problems, including descriptions of polynomial-time algorithms for these core models are presented.
