Towards a Metaphor Visualization

Over the last few months, ROBUST partner Polecat has continued to look into the concept of a metaphor based visualisation. This is more ambitious in scope than using metaphors within the visualisation; instead it is an attempt to create a visualisation that exclusively uses a single metaphor.

Using KONECT to Investigate Graph Sampling Techniques

The University of Koblenz-Landau is currently investigating graph sampling techniques for very large networks. The networks studied in the ROBUST projects such as the business communities of IBM and SAP have such a large size that most conventional network mining algorithms cannot be applied to them easily: One must use clusters of servers to process the whole networks, necessitating huge amounts of computing power, memory and network bandwidth.

Active Dissemination of ROBUST Results at NUIG

Researchers from DERI, NUI Galway submitted three papers on ROBUST topics to the 6TH International AAAI Conference on Weblogs and Social Media (ICWSM 2012). The topics range from behavioural clustering of users for dynamic role analysis, over thread reconstruction for online discussion forums from different domains, to cross-community influence in online forums. Another work on maximising information spread in online forums will be submitted to the Mining Social Network Dynamics workshop at the World Wide Web conference 2012.

Diversity among Enterprise Online Communities

There is a growing body of research into the adoption and use of social software in enterprises. However, less is known about how groups, such as communities, use and appropriate these technologies, and the implications for community structures. In a study of 188 very active online enterprise communities in the internal IBM Connections deployment in IBM, systematic differences in size, demographics and participation, aligned with differences in community types were found.

CORMSIS Develops New Graph Metrics

Online communities are invariably expressed as graphs, ie. as collections of nodes with connections (edges) between each other. An important measure on such a graph is the distance between two nodes, which is often expressed in terms of a shortest route between the given nodes.

Erik Aumayr joins ROBUST Team of NUIG

Erik Aumayr submitted his Diploma thesis on "Reconstruction of Threaded Conversations in Online Discussion Forums". This work was done in the context of the ROBUST project in a collaboration between DERI, NUI Galway and the Ilmenau University of Technology. Erik will soon start as a PhD student in DERI and will focus on similar ROBUST topics.

ROBUST contributes to Apache Giraph

A key focus of ROBUST is the analysis of huge social graphs. For general-purpose big data computation, the map-reduce computing model has been well adopted and the most deployed map-reduce infrastructure is Apache Hadoop. However the map-reduce paradigm is not well suited for processing such large graphs. One of the core tasks of research in the ROBUST project is to identify more suitable and powerful paradigms for implementing large scale graph algorithms.

Trilateral meeting in Milton Keynes

Members from the ROBUST project from IBM, OU, and NUIG got together in Milton Keynes for a two day meeting on 11th and 12th of January to discuss progress and plan joint work. The meeting was focused around the requirements of the IBM use case. Main topics discussed were (a) impact of community type on its activity patterns and behaviour, (b) semantics and models for behaviour analysis, and (c) advanced techniques and algorithms for churn analysis. The meeting was highly effective and resulted in specific joint work and dissemination plans for the next 6 months of ROBUST.

WeST Team Becomes Semantic Web World Champion

The SchemEX system presented by Mathias Konrath, Dr. Thomas Gottron and Jun.-Prof. Dr. Ansgar Scherp from the Institute WeST has won the Semantic Web Challenge in the Billion Triples category at the 10th International Semantic Web Conference, ISWC 2011. SchemEX provides a smart approach for indexing large and distributing graph based data as they appear also in the context of online communities. With Thomas Gottron, also researchers from the ROBUST project have contributed to this success.

ROBUST initiates the Virtual Center of Excellence on Online Communities

Online communities are in the focus of several current research projects. While the focus and aims are always different, some key questions might be of interest across several of these projects. In order to foster the exchange of findings and to discuss ideas ROBUST initiated the Virtual Center of Excellence on Online Communities.

TUB aims to process a 700 million interactions dataset for ROBUST

TU Berlin is currently continuing its work on distributed link prediction and collaborative filtering algorithms. At the heart of these approaches is a pairwise similarity comparison of the columns of an enormous sparse matrix.

Overview of Visualizing Techniques for Online Communities

As part of the next stage of the robust deliverables, Polecat is starting to look at creating a visual metaphor to represent and monitor community health. This still appears to be an underdeveloped area of research, and there are few really pure examples around. Most data still tends to be represented with traditional charts and graphs.

Understanding the Driving Factors of Discussion Activity on Community Forums

Understanding the Driving Factors of Discussion Activity on Community Forums

Online communities have now become the de facto resource for users to ask questions, share opinions and debate and interact with their peers in a social environment. Information contained with such communities is useful to market analysts and brand managers as it informs public opinion towards their products and/or services.

KONECT - The Koblenz Network Collection

The ROBUST project is concerned with the study of large business communities: interconnections between people, interconnections between content items and interconnections between whole communities. These interconnected worlds can be represented as “networks”, i.e. a set set of objects, connected by links. What is special about this new “network science”? It is the connections themselves that become the object of study, and not the items.
