How much detail would you like?
Practical
A specialized procedure for knowledge-based explanation and diagnosis when rules and possible assumptions can be modelled.
Possible example: A diagnostic system generates possible causes of failure from machine malfunctions and rules, which are subsequently tested.
Possible applications: automated fault diagnosis in mechanical engineering, root cause analysis in IT system failures and consistency checking of complex product configurations.
At a glance
- Core
- ALP combines logical rules with possible assumptions that explain observations. Explanations must fit the modelled knowledge base and its conditions; several explanations may be possible.
- Use
- A specialized procedure for knowledge-based explanation and diagnosis when rules and possible assumptions can be modelled.
- Example
- Possible example: A diagnostic system generates possible causes of failure from machine malfunctions and rules, which are subsequently tested.
- Limits
- High computational effort for large knowledge bases, many possible explanation hypotheses and inconsistencies in incomplete sets of rules.
In context
Questions about this term
What is Abductive Logic Programming (ALP)?
ALP combines declarative logic programming with abductive closure to explain observations. Several explanation hypotheses compatible with the rules may be possible.
What should I pay attention to?
High computing complexity for large sets of rules and incomplete data stocks.
All details and background
ALP combines logical rules with possible assumptions that explain observations. Explanations must fit the modelled knowledge base and its conditions; several explanations may be possible.
ELI5 – Explained simply
Like a detective with a rulebook: Wet roads can be explained by rain, but also by a street cleaning. The declaration must be examined.
Why it matters in practice
A specialized procedure for knowledge-based explanation and diagnosis when rules and possible assumptions can be modelled.
Example
Possible example: A diagnostic system generates possible causes of failure from machine malfunctions and rules, which are subsequently tested.
Pitfalls and limits
- High computational effort for large knowledge bases, many possible explanation hypotheses and inconsistencies in incomplete sets of rules.
Origin & history
Kakas, Kowalski and Toni published an overview of Abductive Logic Programming in 1992; Kowalski’s directory already mentions relevant abduction work in 1989.
Use in mid-sized companies
- Possible applications: automated fault diagnosis in mechanical engineering, root cause analysis in IT system failures and consistency checking of complex product configurations.
