  1. Linguistic Resources for the 2013 TAC KBP Cold Start Evaluation Joe Ellis (presenter), Jeremy Getman, Jonathan Wright, Stephanie Strassel Linguistic Data Consortium University of Pennsylvania, USA

  2. Query Selection • Annotators search and annotate chains of entities connected by KBP slots • Cold Start queries comprised of • Entity Appleton Museum of Art org:top_members_employees John Lofgren per:title director TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  3. Query Selection • Annotators search and annotate chains of entities connected by KBP slots • Cold Start queries comprised of • Entity – Slot 0 Appleton Museum of Art org:top_members_employees John Lofgren per:title director TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  4. Query Selection • Annotators search and annotate chains of entities connected by KBP slots • Cold Start queries comprised of • Entity – Slot 0 – Slot 1 • Inverse slots to increase connectivity • e.g. per:cities_of_residence– gpe:residents_of_city Appleton Museum of Art org:top_members_employees John Lofgren per:title director TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  5. Query Selection • Annotators search and annotate chains of entities connected by KBP slots • Cold Start queries comprised of • Entity – Slot 0 – Slot 1 • Inverse slots to increase connectivity • e.g. org:founded_by– {per,org,gpe}:organizations_founded Appleton Museum of Art org:top_members_employees John Lofgren per:title director TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  6. Query Selection • Annotators search and annotate chains of entities connected by KBP slots • Cold Start queries comprised of • Entity – Slot 0 – Slot 1 • Inverse slots to increase connectivity • e.g. org:top_members_employees –per:top_member_employee_of • Cold Start corpus • KBA output • Comprised of web documents from Ocala, FL; Kentucky; Guyana Appleton Museum of Art org:top_members_employees John Lofgren per:title director TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  7. Annotation • Unlike other SF tasks, Cold Start annotation is performed concurrently with query development • Multiple fillers at each “hop” level, all of which must be annotated and correctly connected to one another • London – gpe:residents_of_city – per:charges • Lance Barrett • first-degree attempted burglary • theft of a firearm • carrying a concealed weapon • Lesa Bailey • criminal conspiracy to make meth • unlawful possession of meth precursors • possession of a controlled substance TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  8. Assessment • Assess validity of fillers &justification from humans & systems • Filler • Correct – meets the slot requirements and supported in document • Wrong – doesn’t meet slot requirements and/or not supported in doc • Inexact – otherwise correct, but is incomplete, includes extraneous text, or is not the most informative string in the document • Predicate • Correct, Wrong, Inexact-Short, Inexact-Long • Subject/Object • Correct, Wrong, Inexact • Ignore TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  9. New in 2013: Justification • Justification is the string(s) of text that show a relation is true • Predicate: Includes all three pieces of information necessary to justify the entity/slot/filler relation • Subject: proves the entity’s involvement in the relation • Object: proves the filler’s involvement in the relation • Each part can be comprised of up to two, discontiguous strings • <Harkat-ul-Mujahideen - org:country_of_headquarters - Pakistan> • Predicate 1: the Islamabad headquarters of Harkat-ul-Mujahideen • Predicate 2: Islamabad, the capital city of Pakistan Ronnie James Dio -per:date_of_death: Sunday [2010-05-16] TAC KBP Evaluation Workshop – NIST, November 18-19, 2013

  10. 2013 Discoveries • New justification scheme used in unexpected, creative ways • Additional predicate strings used to disambiguate entities • <VitalyGinzburg - per:cause_of_death - cardiac arrest> • Predicate 1: Ginzburg died late Sunday of cardiac arrest. • Predicate 2: VitalyGinzburg, a Nobel Prize-winning Russian physicist and one of the fathers of the Soviet hydrogen bomb TAC KBP Evaluation Workshop – NIST, November 18-19, 2013
