DESCRIPTION:By : Gerhard Weikum - Max-Planck Institute for Informatics (MP
 II)Video of his talkAbstract :\nNews\, social media\, web sites\, and ente
 rprise sources produce huge amounts of valuable contents in the form of te
 xt and speech. To tap this wealth of unstructured Big Data and obtain insi
 ghts\, a decisive step is to identify the entities that are referred to an
 d relationships between entities. This allows linking unstructured content
 s with structured data. However\, this step faces the fundamental problem 
 that names and phrases are often highly ambiguous\; mapping them to entiti
 es and relations is a challenging task. The talk will discuss the state of
  the art\, applications\, and open problems on disambiguating named entiti
 es in text and heterogeneous tables. It will also put this line of researc
 h in perspective to the bigger picture of Big Data analytics.Bio :\nGerhar
 d Weikum is a Scientific Director at the Max Planck Institute for Informat
 ics in Saarbruecken\, Germany\, and also an Adjunct Professor at Saarland 
 University. He graduated from the University of Darmstadt\, Germany. Weiku
 m's research spans transactional and distributed systems\, self-tuning dat
 abase systems\, DB&IR integration\, and the automatic construction of know
 ledge bases from Web and text sources. He co-authored a comprehensive text
 book on transactional systems\, received the VLDB 10-Year Award for his wo
 rk on automatic DB tuning\, and is one of the creators of the YAGO knowled
 ge base. Gerhard Weikum is an ACM Fellow\, a member of several academies i
 n Germany\, and currently serves on the German Council of Science and Huma
 nities. He has served on various editorial boards\, including Communicatio
 ns of the ACM and ACM TWEB\, and as program committee chair of conferences
