The objective of this topical issue is to collect and report on recent high-quality researches that combine semantics and knowledge engineering to social networks and their different contextualization types.
As semantic social networks, we consider social networks that incorporate Web 3.0 technologies for semantifying the information associated with them as well as their diffused content. Semantic social networks can be also seen as tools to model knowledge from multidisciplinary social media and scattered online communities.
Thus, as social networking data grows exponentially and semantic technologies become more and more established, interesting research issues emerge. Matters arise in respect to identification and modelling of complex and evolutionary patterns using computational intelligence and data mining techniques, discovery and analysis of online communities, personalization and identification of OSN user behavior/activity etc. This topical issue aims at increasing the awareness of researchers in these fields, as well as providing an in-depth investigation on various research and related deployment issues.

Topics of interest include, but are not limited to the following semantic and social network dynamics aspects:
- Content creation, annotation and modelling for social networks/media
- Modelling crowd-sourcing analysis (opinions, influence, sentiment etc.)
- Semantically-Interlinked Online Communities
- Semantic context modelling and extraction
- Social and semantic media collaboration platforms (e.g. semantic wikis)
- Social network aggregation
- User modelling and dynamic profiling
- Adaptive and personalized content provision in OSNs
- Content-based, user-based, and network-based semantics
- Hybrid socio-semantic approaches for profiling and recommendation
- Social media information and controlled vocabularies (e.g. FOAF, SKOS, SIOC)
