DESCRIPTION:Spoken content retrieval (SCR) has been the focus of various r
 esearch initiatives for more then 20 years. Early work focused on developm
 ent of small private test collections in the mid-1990s. This was followed 
 by the first open benchmark evaluations of SCR in the spoken document retr
 ieval (SDR) at TREC-6-9. The end of which saw SDR declared a largely solve
 d problem. However\, this soon found to be a premature conclusion relating
  to controlled recordings of professional news content and overlooking man
 y of the potential challenges of searching more complex spoken content. Su
 bsequent research has focused on more challenging tasks such as search of 
 interview recordings and semi-professional internet content.\n\nThis talk 
 will begin by reviewing early work in SDR\, explaining its successes and l
 imitations\, it will then move to outline research exploring SCR for more 
 challenging tasks\, such as identifying relevant elements in long spoken r
 ecordings such as meetings and presentations\, provide a detailed analysis
  of the characteristics of retrieval behaviour of spoken content elements 
 when indexed using manual and automatic transcripts\, and finally conclude
  with a summary of the challenges of delivering effective SCR for complex 
 spoken content.\n
