4th Int. Alexandria Workshop (19./20. October 2017)

Foundations for Temporal Retrieval, Exploration and Analytics in Web Archives

19./20. October 2017

Significant parts of our cultural heritage are produced on the Web, yet only insufficient opportunities exist for accessing and exploring the past of the Web. While the easy accessibility to the current Web is a good baseline, optimal access to Web archives requires new models and algorithms for retrieval, exploration, and analytics which go far beyond what is needed to access the current state of the Web. This includes taking into account the unique temporal dimension of Web archives, structured semantic information already available on the Web, as well as social media and network information.

The workshop aims at bringing together communities involved in information retrieval, social network analysis and NLP to encourage a closer dialogue between researchers..
