Interaktiv kartgenerator för att förenkla och förtydliga viktiga strukturer i stora nätverk (Swedish)
Abstract [en]

Understanding the structure of a network is an essential part in understanding the behavior of the system it represents, but as the system becomes really large, a visualization of the full network looses its potential to reveal important structural relationships. Then we need ways to simplify and highlight the important structures of the network while the details are filtered out, just like good maps do. We have developed an interactive application that utilizes mathematical methods based on network and information theory to reveal the important patterns hidden in huge amount of interaction data. The application gives the professional as well as the nonprofessional user the ability to load his or hers own file containing the network data, from mobile phone networks and social online networks to transport networks and financial networks and lets you explore the data and generate a customized map which highlights the influential patterns in your data. A demo application is also developed to demonstrate the mathematical and information-theoretical principles behind the map generation.

Abstract [sv]

För att koppla form till funktion är nätverk ett oumbärligt verktyg, men när systemen blir riktigt stora förlorar nätverken sin förmåga att avslöja viktiga strukturella samband. Då behövs det kraftfulla metoder för att förenkla och framhäva de viktiga strukturerna i nätverken samtidigt som detaljerna filtreras bort, precis som bra kartor gör. Vi har utvecklat en interaktiv applikation som utnyttjar matematiska metoder baserat på nätverks- och in- formationsteori för att avslöja viktiga mönster som ligger dolt i myllret av interaktionsdata. Du kan läsa in din egen fil med nätverksdata, från telekommunikationsnätverk och sociala online-nätverk till transportnärverk och finansiella nätverk, och få tillbaka en skräddarsydd karta som låter dig upptäcka de inflytelserika mönstren i nätverket. En demo-applikation är också utvecklad för att demonstrera de matematiska och informationsteoretiska principerna bakom kartgenereringen.
