Public Methods

Method	Description
SPARQLQueryBuilder ( ) : System	The constructor of the class, initiates the vars
buildQueries ( string object1, string object2, int maxDistance, int limit, List ignoredObjects = null, List ignoredProperties = null, int avoidCycles ) : List	Builds and returns a set of queries to find relations between two object1 and object2.

Private Methods

Method	Description
completeQuery ( string coreQuery, Dictionary options, Dictionary vars ) : string	is thefunction that takes the Sparql Query from Direct and ConnectViamiddleObject functions and complete it it takes the part after where {.... , and completes it depending on the options
connectedViaAMiddleObject ( string first, string second, int dist1, int dist2, bool toObject, Dictionary options ) : string	Return a set of queries to find relations between two objects which are connected via a middle objects $dist1 and $dist2 give the distance between the first and second object to the middle they have ti be greater that 1
direct ( string object1, string object2, int distance, Dictionary options ) : string	Returns a query for getting a direct connection from $object1 to $object2.
expandTerms ( List terms, string ooperator = "&&" ) : string	puts bracket around the (filterterms) and concatenates them with &&
generateFilter ( Dictionary options, Dictionary vars ) : string	generates the necessary Filters
getQueries ( string object1, string object2, int distance, int limit, List ignoredObjects = null, List ignoredProperties = null, int avoidCycles ) : List>.Dictionary	Return a set of queries to find relations between two objects.
listToString ( List inputList ) : string	takes a list and converts it to a string(list must be of count 1)
stringToLoist ( string input ) : List	takes a string and converts it to a list of strings of count1
toPattern ( string s, string p, string o, bool toObject ) : string	this function puts the query terms subject, predicate, object
uri ( string x ) : string	takes the object name and returns the URI link to easily use in Sparql Query

Method Details

SPARQLQueryBuilder() public method

The constructor of the class, initiates the vars

public SPARQLQueryBuilder ( ) : System
return	System

buildQueries() public method

Builds and returns a set of queries to find relations between two object1 and object2.

public buildQueries ( string object1, string object2, int maxDistance, int limit, List ignoredObjects = null, List ignoredProperties = null, int avoidCycles ) : List
object1	string	object1
object2	string	object2
maxDistance	int	MaxiumDistance between the two objects
limit	int	Limit of results
ignoredObjects	List	List of strings of names of objects be ignored in the Queries for example : http://dbpedia.org/resource/thing
ignoredProperties	List	List of strings of names of properties to be ignored in the Queries
avoidCycles	int	Integer value which indicates whether we want to suppress cycles , 0 = no cycle avoidance , 1 = no intermediate object can be object1 or object2 , 2 = like 1 + an object can not occur more than once in a connection
return	List
