3 2012 Task: Filtering to Recommend Citations 1)Initialize with a target WP entity state of WP from Jan 2012 2)Iterate over stream of text items Oct-Dec 2011: train on labels 3)For each, output confidence between 0, 1 Jan-Apr 2012: labels hidden Content Stream 462M texts, 40% English 4,973 hourly chunks of a 10 5 docs/hour News, blogs, forums, and link shortening Content Stream 462M texts, 40% English 4,973 hourly chunks of a 10 5 docs/hour News, blogs, forums, and link shortening Your KBA System Entities in Wikipedia or another Knowledge Base Automatically recommend new edits Diffeo Sponsors:

6 Accelerate? rate of assimilation << stream size # editors << # entities << # mentions (definition of a “large” KB)

7 How many days must a news article wait before being cited in Wikipedia?

8 Complex entity with many relationships and attributes.

9 Has many interests, including trying to takeover UK soccer teams. His empire includes many entities… Note: Usmanov not mentioned in this text! Citation #18 Elaborate link trails…

10 Example KBA Rating Task Published: March 31, 2012 Impact of Thoughts on Water By Denis Gorce-Bourge Water covers 70% of our Blue planet and our body is made of about 70% water. Masaru Emoto is a Japanese Photographer and scientist. He is known over the world for his remarkable work on water and its deep connection with individual and collective consciousness. For decades, Masaru took pictures of frozen crystals of water and tested the direct influence of the environment on the quality of those crystals. Pollution has a direct impact on the beauty of a frozen crystal but as well words, music and thoughts. He tested the quality of water crystals by exposing it to various conditions: to written words like hate and violence and Love and gratitude. The results were just astonishing. The crystal exposed to Love and gratitude was beautiful and perfectly formed where the other one was severely degraded. He demonstrated as well the impact of Heavy Metal music versus Mozart or Beethoven and how the vibration of music impacts water. The very shape of water crystals is modified by violence, aggression, and negative words.

18 KBA 2013 More entity types with an emphasis on temporality in the stream. Target EntitiesKBCentrally Relevant Training DataAnnotation People and Organizations Wikipedia or maybe Freebase Citation worthyJudgments from early stream High recall on all mentioning docs. Pharmaceutical Compounds Merck KB?Reporting of Adverse Drug Reaction (ADR) (an event) (same)Focus recall on first person reporting & negative reactions? Event-type Entities Defined by a cluster of entities and possibly a Type-of-Event from a taxonomy WP/FB for cluster of entities, possibly also event itself. Provides causality info Judgments on docs for that Type-of-Event but different specific event. Find training data from TDT? Use citations in Category:Current _events? Judge post-hoc?

19 KBX Cold Start queries focused on: nil entities related to target cluster and/or causality of event Pool top-K filtered docs, or use each KBA run as separate KBP input. (1000x filter) Must coordinate choice of KBA target entities with desired content of KBs for Cold Start queries.
