Monitoring the Wrappers Under Verification¶
The verification graphical tool lets users monitor the execution of the wrappers that have been loaded into the Wrapper Server. This can be achieved by using the following tabs:
Tests: this tab displays information about the tests that have been executed, and their results. The information available is the following:
Wrapper: database and wrapper name
Test: name of the test that has been executed
Date: execution date
Score: test result. This score indicates the percentage of agreement of the results with the test’s criterion, where 0 means complete agreement and 100 a complete disagreement.
Passed: it reports whether the test was successful or not (if so, it does not participate in the rule activation).
Message: provides additional information about the execution.
Queries: this tab displays information about the queries that have been executed against the wrappers.
Wrapper: database, wrapper and, optionally, Extractor component name.
Query: query that has been executed against the Wrapper Server.
Date: execution date.
Results: number of returned results
Pages: if related to an Extractor component, number of pages used in execution; if related to a wrapper, the value is always 1.
Database: this tab displays all information stored in the verification database. It is divided in two additional tabs, which are shown with the symbol .
Tab 1: information about the wrappers that are stored in the verification database.
Wrapper: database and wrapper name
Extractors: name of the wrapper’s Extractor components
Valid Data: number of queries and results not outdated stored in the verification database for that wrapper.
Outdated Data: number of queries and results outdated stored in the verification database for that wrapper.
Tests: number of tests stored in the verification database for that wrapper.
Tab 2: information about the wrapper that is selected in the selection box.
Wrapper: database, wrapper and Extractor component name
Query: query used for executing the wrapper
Date: execution date
Row: number of results for this query execution
Status: status of the execution (correct, incorrect, …)
ID: execution identifier
View: button to access detailed information. It will open a new tab showing internal information about this identifier.
Graphs: this tab shows different graphs from the wrappers and the tests that have been executed in a specific timeframe. The choice of which wrappers and tests are to be supervised must be done before the wrapper starts being executed.
