9. Experiments DataSet Approaches Task KB: DBpedia
Text corpora: AQUAINT,IITB
Approaches
DESC, CHR, DFF, CNT, COMB, RELIN
Task
Choose correct entity from three candidate entities according the entity mention and its context
Rate and comment

10. Evaluation Extrinsic Evaluation
30 students, each for a total of 72 tasks, or 36 tasks from each corpora

11. Evaluation Intrinsic Evaluation
Dominating factors: characterizing power and information overlap

12. Evaluation Intrinsic Evaluation Comments: CHR： DFF COMB 53% IITB
highly distinguishing features
50%
IITB
different types helped them filter out noise entities easily
60%
AQUAINT
apart from different types, almost no useful information
80%
IITB
some highly distinguishing features
90%
AQUAINT
53%
comprehensive information was provided
