- Abstract
- Classical knowledge representation methods traditionally work with established relations such as synonymy, hierarchy and unspecified associations. Recent developments like ontologies and folksonomies show new forms of collaboration, indexing and knowledge representation and encourage the reconsideration of standard knowledge relationships. In a summarizing overview we show which relations are currently utilized in elaborated knowledge representation methods and which may be inherently hidden in folksonomies and ontologies.

- Abstract
- The state of Twitter research in the social science do main is investigated based on a set of 25 highly cited papers, identified with the Scopus database out of 370 social science publications on social media research. The analysis shows how social media research in the so cial sciences has risen since 2007. The selected top cited papers are analyzed concerning their domains, the applied methods and the underlying data in use. It is shown that different methods, both experimental and analytical are applied, and that some papers have started to combine different modes of analysis. The size of the datasets used for studying Twitter varies considerably across studies. Furthermore, central advantages of studying data collected from Twitter are pointed out and open challenges in working with these particular data are listed. Challenges include, for example, data access via the Twitter API or via third party tools, representativeness of datasets and sampling strategies and ethical issues.
