Aggregating Social Media for Enhancing Conference Experiences

  1. 1. Aggregating Social Media for Enhancing Conference Experiences Houda Khrouf , Ghislain Atemezing, Giuseppe Rizzo, Raphaël Troncy and Thomas SteinerReal-Time Analysis and Mining of Social Streams, 2012, Dublin, Ireland
  2. 2. What happened in ICWSM-12? How to get a summary? • Spread Information • Keyword Search • Short life of some media (e.g. tweets) 6/3/2012 RAMSS2012, Dublin, Ireland -2
  3. 3. Overview Create a real-time environment to browse conferences as well as their various representative media items: images, micro- posts, slides, videos, etc. Best Concept award in the "Linked Data-a-Thon" challenge of ISWC 2011. “Confomaton” Semantic Web Application 6/3/2012 RAMSS2012, Dublin, Ireland -3
  4. 4. Confomaton architecture Media Collector Data (Node.js) Real-time Reconciliation Modelling Based on Event Collector Tag + Named-Entity (RSS, dumps) Linked Data API User Interface 6/3/2012 RAMSS2012, Dublin, Ireland -4
  5. 5. Media Collector Runs on the top of Node.js Collects media items and stories via search input terms using the social media search API (Flickr, Twitter, Slideshare, etc.) 6/3/2012 RAMSS2012, Dublin, Ireland -5
  6. 6. Media Collector 6/3/2012 RAMSS2012, Dublin, Ireland -6
  7. 7. Event Collector Lanyrd providing RSS feeds of about 250 conferences per month Semantic Web Dog Food providing RDF fine-grained descriptions of conferences: • Sub-events (tutorials, talks, sessions, etc.) • Papers that were presented • People who attended and the organizations they come from. 6/3/2012 RAMSS2012, Dublin, Ireland -7
  8. 8. Data Modelling for EventsLODE Ontology 6/3/2012 RAMSS2012, Dublin, Ireland -8

  10. 10. Real-Time ReconciliationTag-based Mapping + Filtering by time 6/3/2012 RAMSS2012, Dublin, Ireland - 10
  11. 11. Real-Time ReconciliationIf there is no tag? Named-Entity based Mapping Peter Mika: RDF indexing via MapReduce, triples are grouped into documents by subjects #iswc2011 The paper in which the description encapsulates these named-entities Precision = 61% The related event 6/3/2012 RAMSS2012, Dublin, Ireland - 11
  12. 12. Statistics Conferences and Media Items their sub-eventsSemantic Web Dog Food 173 4 187Lanyrd 1 270 572 204And more statistics?

  13. 13. Technology RDF Storage:  Backed up by Virtuoso (RDF triple store) SPARQL endpoint:  LDA: Linked Data API  A set of REST methods to publish the data stored in the RDF storage behind User Interface:  HTML + CSS + Javascript 6/3/2012 RAMSS2012, Dublin, Ireland - 13
  14. 14. Demos Media 6/3/2012 RAMSS2012, Dublin, Ireland - 14
  15. 15. Lessons Learned Easy integration of existing technologies  Limitation of some services: e.g: max 500 requests/day for some API User Interface: important BUT time consuming  Not easy to create and manage the “all in one” interface  How to ensure an effective navigation of a large space of interconnected resources  A lot of effort from Semantic Web community 6/3/2012 RAMSS2012, Dublin, Ireland 15
  16. 16. Future Work Integrate the other media services and media items Enrich events descriptions with further information Refine the reconciliation algorithm Improve the performance of the user interface. Data exploration: sentiment analysis, ranking, etc. 6/3/2012 RAMSS2012, Dublin, Ireland - 16
