The 5th Leipziger Semantic Web Tag (LSWT2013) was organized as a meeting point for german as well as international Linked Data experts. Under the motto: From Big Data to Smart Data sophisticated methods that enable handling large amounts of data have been presented on September 23th in Leipzig. The keynote was held by Hans Uszkoreit, scientific director at the German Research Center for Artificial Intelligence (DFKI). By being introduced  to Text Analytics and Big Data issues the participants of the LSWT 2013 discussed the intelligent usage of huge amounts of data in the web.

Presentations on industrial and scientific solutions showed working solutions to big data concerns. Companies like Empolis, Brox and Ontos presented Linked Data and Semantic Web solutions capable of handling terabytes of data. However, also traditional approaches, like Datameer’s Data Analytics Solution based on Hadoop pointed out that big data could be handled nowadays without bigger problems.

Furthermore, problems detecting topics in massive data streams (Topic/S), document collections (WisARD) or corpora at information service providers (Wolters Kluwer) were tackled. Even the ethical issue of robots replacing journalists by the help of semantic data has been examined by Alexander Siebert from Retresco.

In conclusion, the analysis of textual information in large amounts of data is an interesting and so far not yet fully solved area of work. Further Information are available from the website.

Further information on topics related to data analysis, data curation, data storage, data acquisition and data usage can be found in our technical whitepaper available from our project website.

Call for papers
Special Issue on Web Data Quality
International Journal on Semantic Web and Information Systems

Scope:

The standardization and adoption of Semantic Web technologies has resulted in an unprecedented volume of data being published as Linked Open Data (LOD). The integration across this Web of Data, however, is hampered by the ‘publish first, refine later’philosophy. This leads to various quality problems arising in the underlying data such as incompleteness, inconsistency and incomprehensibility. These problems affect every application domain, be it scientific (e.g., life science, environment), governmental or industrial applications.

This Special Issue is addressed to those members of the community interested in providing novel methodologies or frameworks in assessing, monitoring, maintaining and improving the quality of the Web of Data and also introduce tools and user interfaces which can effectively assist in the assessment. The benefits of such methodologies will not only help in detecting inherent data quality problems currently plaguing the Web of Data, but also provide the means to fix these problems and maintain the quality in the long run. Additionally, we also seek articles that help identify the current impediments in building real-world LOD applications

Topics:

Web data and LOD quality concepts

Scalability and performance of tools
