  1. Social Context as a part of News-Archive-ExplorerWeb application for exploratory browsing of news streams and archives Marko Grobelnik JasnaŠkrbec Jozef Stefan Institute

  2. Introduction • News publishers generate content archives • The goal is to build a system to make such archives usable through text mining & visualization • Archive characteristics: • Large corpora (up-to few M articles) • Rich meta data (specific for each archive) • Different input formats (xml structure) • Poor search interfaces (not specialized for archives)

  3. What we want? • Application to… • help user search and browse through archives • help user read more about topics related to search • visualize how things are connected in time, place, stories, etc. • get user’s attention and interest in other related issues • tell more about searched content

  8. Showing relationships between entities

  9. Plans for the future • Improve search (with narrowing criteria, suggestions) • Adding visualizations to show content in time, space and other contexts • Adding links to similar content (stories) • Adding links to outside resources (like dbpedia) or bring this resources inside this application • Integrate with tools developed in AILab to improve search and presentation of articles (SearchPoint, DocAtlas, …) • Improve usability & appearance of user interface
