+## Overview dell'approccio come presentato da Riccardo
+![[Pasted image 20210116102546.png]]
+
+Molto simile al paper [[AMMORE.pdf]]. La differenza è che la query viene generata automaticamente.
+## Overview dell'approccio proposto

+
+**User input**: It consists of the current metamodel being developed, which includes OCL statements 
+
+**Input of the approach**: It consists only of the metamodel being specified.
+
+**Lucene-based tool**: It retrieves:
+	1) metamodels that similar to the one given in input
+	2) The metamodels retrieved in 1) are used to retrieve OCL statements that can be used to complete the specification of the metamodel being developed.
+
+**Ranking tool**: It takes as input the retrieved OCL statements, a ranking policy, and it generates the ranked list of OCL statements.
+## Evaluation
+For the **Evaluation** we apply the following process:
+
+1) We create a dataset of metamodels containing OCL statements (this represents the GT)
+2) We remove from the dataset in 1) all the OCL statements
+3) We apply the approach on all the metamodels in 2) and compare the recommended OCL statements with those in the GT.
+	1) **Issue:** we need to identify the similarity function to be used for comparison.
