Recursive algorithms to repair prioritized and inconsistent dl-lite knowledge base
The inconsistency in prioritized knowledge base is because the assertions
(ABoxes) come from several sources with different levels of reliability. We
introduce the handling of this inconsistency problem to query inconsistent
\textit{DL-Lite} knowledge bases. In the literature, firstly, repair all the
inconsistent assertions of the \textit{DL-Lite}'s inconsistent knowledge base.
Then, interrogate it. However, our algorithm, on proceeds directly with an
interrogation of the knowledge base in order to recover an exhaustive list of
answers to a given query. In a second time, to repair the answers of this list.
The novelty of our article is the proposition of a recurring function that
calculates the rank of coherence in order to manage the inconsistencies in the
set of responses. This strategy allowed us to reduce execution time compared to
existing algorithms. The experimental study as well as the analysis of the
results, which we carried out, showed that our algorithm is much more
productive than the other algorithms since it gives the greatest number of
answers while remaining the best from the point of view of the execution time.
Finally, as shown in our experimental studies, they allow an efficient handling
of inconsistency. Such facts make all the repairs suitable for \textit{DL-Lit
