ANAPSID

* source:

 https://github.com/anapsid/anapsid

* execute:

run_anapsid -e $ENDPOINTS -q $query -p <planType> -s False -o False -d <TypeofDecompostion> -a True -w False [-k <special>]  [-V <typeOfEndpoint>] -r False

$ENDPOINTS: path and name of the file where the description of the endpoints is stored.

$query: path and name of the filw where the query is stored.

<planType>: can be b if the plan is bushy, ll is the plan is left linear, and naive for naive binary tree plan.

-o: can be True or False. True indicates that the input query is in SPARQL1-1 and no decomposition is needed; False, otherwise.

-d: indicates the type of Decomposition. can be SSGM (Star Shaped Group Multiple Endpoints), SSGS (Star Shaped Group Single Endpoint), EG (Exclusive Groups), Recommended SSGM.

-a: indicates if the adaptive operators will be used. Recommended value True.

-w: can be True or False. Indicates if the cardinality of the queries will be estimated by contacting the sources (True) or by using a cost model (False). Turning True this feature may affect execution time.

-k: can be y or c. The value y indicates that the plan will be produced, while c asks that decomposition. This parameter is optional, and should be set up only if the plan of the query wants to be produced.

-r: can be True or False. Use True if the answer of the query will be output and False if only a summary of the execution will be produced.

-V: can be True or False. True indicates if the endpoints to contact are Virtuoso, False is of any other type, e.g., OWLIM.

* Result:

when using only the two actually queried endpoints( pharmgkb and omim):

Query\time(ms)	time 1	time 2	time 3	time 4	time 5
