10 Questions
What is the main difference between the model discussed and theirs?
Handling dependence between sources
How does TRUTH FINDER address the possible dependence between sources?
By using a dampening factor
In the motivating example, what issue arises with TRUTH FINDER's approach to source dependence?
It incorrectly decides that all values provided by S3 are true
How does the model discussed handle dependence between sources?
By examining the probability of dependence
What does the model discussed consider when examining the probability of dependence between data sources?
The probability that a pair of data sources are dependent
What metric is used to compute confidence of affiliations in the motivating example?
Precision score
What does 'f (d), d ∈ [0, 1], as the percentage of false values R1 whose distribution probability is d' represent?
Percentage of false values with distribution probability d
'f (d)' is defined as the percentage of false values whose distribution probability is d; what does it imply about values with 'f (d) = 1'?
'f (d) = 1' suggests all values are false
'P r(O ∈ Ōf |S1 ⊥S2 ) = ε(S1 )ε(S2 )' is related to which concept?
Dependence between sources
'R1 2 d f (d)' is used to compute what specific probability in the given text?
'R1 2 d f (d)' determines false-value providers' alignment likelihood
Explore the impact of source accuracy on perception of dependence between sources, and learn about computing accuracy in vote counting using the ACCU model. Delve into creating probabilistic distributions for objects in a domain and choosing true values based on probabilities.
