1 Introduction
Mining and analyzing social networks is now becoming a very popular
research area not only for data mining and web mining but also social
network analysis. Data mining is a technique that has the ability to
process and analyze large amounts of data and by this to discover
valuable information from the data. In recent years, due to the
booming of social communications and social network-based web
services, data mining has become a very important and powerful
technique to process and analyze such large amounts of data.
Recently, many researchers are focusing on developing new data mining
techniques and algorithms, or devoting themselves to improve
traditional mining techniques for social network analysis. However,
this is meaningless, if the discovered valuable and useful data have
not been applied in real environment of application. Social data are
the aggregations of communication interaction and experience of
people, and it is useful to leverage this type of data for
decision-making, such as data from Facebook or Twitter. Thus, it could
be an important time to shift the research focus to an application
area, such as decision support.
This special issue invited papers of the following topics:
- Mining and analyzing social data for decision support
- Mining social web services for decision support
- Algorithms for mining social networks for decision support
- Matching engines and interfaces for decision support systems
- System architectures
- Intelligent and multi-agent based decision support systems
- Social decision support systems
- Semantic Analysis for Decision Support
- Opinion Mining and Sentiment Analysis
- Big Data Issue in Mining and analyzing social data for decision support
- Visualization
- Experiment and implementation
- Leveraging social data for decision support in healthcare
- Case studies and empirical studies
2 Contributions to the Journal Special Issue
In this special issue, we invited authors to submit extended version
of their papers, which are selected top quality papers from MISNC 2015
(The 2nd Multidisciplinary International Social Networks Conference,
Matsuyama, Japan), MSNDS 2015 (The 6th International Workshop on
Mining and Analyzing Social Networks for Decision Support, Paris,
France) and ASE SocialInformatics 2015 (Kaohsiung, Taiwan). In
addition to the invited papers, we also called for public
submissions. Totally, we have received 34 submissions for this special
issue and 8 papers are finally accepted (the acceptance rate is
24%). Each submission was reviewed by at least three experts and
revised according to reviewers' comments to ensure the quality of
the papers.
The first paper is entitled "Calculating Exact Diameter Metric of
Large Static Graphs" and was authored by Masoud Sagharichian, Morteza
Alipour Langouri and Hassan Naderi. The authors propose an algorithm
to calculate the diameter of social graph. Diameter is a very
important measurement in the area of social networks analysis that can
be used to measure how close the nodes in a social network. The
experiment shows the proposed algorithm can quickly detect exact
diameter of large-scale real world graph with a few number of
breadth-first searches.
The second paper is entitled "A Domain Ontology in Social Networks for
Identifying User Interest for Personalized Recommendations" and was
authored by Rung-Ching Chen, Hendry and Chung-Yi Huang. The authors
design an ontology combine with social network by using user interests
and community influences. The cold-start problem can be well solved
through the ontology and recommendation system. Cold-start is a
critical problem for most recommendation system and therefore the
contribution of this paper is significant.
The third paper is entitled "Going beyond your Personal Learning
Network, using Recommendations and Trust through a Multimedia
Question-Answering Service for Decision-support: a Case Study in the
Healthcare" and was authored by Patricia Santos, Sebastian Dennerlein,
Dieter Theiler, John Cook, Tamsin Treasure-Jones, Debbie Holley, Micky
Kerr, Graham Attwell, Dominik Kowald and Elisabeth Lex. The authors
study three healthcare networks to understand how to enable the
building, maintaining and activation of new contacts at work and the
exchange of knowledge. A case has been studied to show the importance
of scaffolding strategies as well as strategies to aggregate trust
when sharing resources and decision support.
The fourth paper, entitled "Dynamic Model of Reposing Information
Propagation based on Empirical Analysis and Markov Process" was
authored by Gui-Xun Luo Yun Liu and Zhi-Yuan Zhang. The authors use
data from Sina Weibo for empirical study and according to the results
build a dynamic information propagation model. The proposed model
shows better adaptability and predictability than traditional
information diffusion models.
The fifth paper, entitled "Social Media Battles: Their Impact during
the 2014 Greek Municipal Elections" was authored by Georgios Lappas,
Amalia Triantafillidou, Prodromos Yannas, Anastasia Kavada, Alexandros
Kleftodimos and Olga Vasileiadou. The authors present an interesting
study to examine the use of social media by candidates running for the
2014 Greek municipal election. The authors conclude some interesting
findings, for example, challengers seem to prefer Facebook and Twitter
as campaign tools. Another important finding is that a candidate's
Facebook page and YouTube channel popularity indicates the candidate's
vote share.
The sixth paper, entitled "Mining Social Networks for Calculation of
SmartSocial Influence" and authored by Vanja Smailovic and Vedran
Podobnik proposes an approach to focus on a research challenge about
the identification of the most influential actors in a social
network. The approach combines relationships among same actors in
communication domain and social networking service domain.
The seventh paper, entitled "Fuzzy Modeling of User Behaviors and
Virtual Goods Purchases in Social Networking Platforms" was authored
by Jarosław Jankowski Kostas Kolomvatsos Przemysław Kazienko and
Jaros#322;aw Wątróbski. The authors present a so-called Fuzzy logic
inference model to analyze purchases based on the types of past
transactions and social activity. The model is helpful to understand
more about customers' purchase behaviors, as well as for decision
making.
The eighth paper, entitled "Detection of the Spiral of Silence Effect
in Social Media" was authored by I-Hsien Ting. The author proposes a
methodology to discover the spiral of silence effect in social media,
such as Facebook and Twitter. The effect of the spiral of silence is
created when users discover their opinion is not the major one in the
social media and they will start to keep silent. The proposed
methodology is very helpful to improve the quality and accuracy of
opinion mining.
