%iKnow.Queries.CcAPI

deprecated class %iKnow.Queries.CcAPI extends %iKnow.Queries.AbstractAPI

The InterSystems IRIS NLP iKnow technology is now deprecated. Please see the product documentationOpens in a new tab for more detail.

This is the main Query API to get access to Concept-Concept pairs (CCs). CCs are an abstraction of CRCs, aggregating them across relationships to focus only on those concepts that are in a direct relationship with one another, without caring about the actual relationship linking the two.

Parameters

parameter GetByEntitiesRT = HeadEntUniId:%Integer,HeadEntity:%String,TailEntUniId:%Integer,TailEntity:%String,frequency:%Integer,spread:%Integer,ccUniId:%Integer;

Methods

classmethod GetByEntities(ByRef result, domainid As %Integer, entitylist As %List, page As %Integer = 1, pagesize As %Integer = 10, filter As %iKnow.Filters.Filter = "", filtermode As %Integer = $$$FILTERONLY, positionstomatch As %Integer = $$$USEPOSHT, sorttype As %Integer = $$$SORTBYDOMAINDEFAULT, pActualFormOnly As %Boolean = 0) as %Status

This method will return all CC pairs in which any (if setop = $$$UNION) or all (if setop = $$$INTERSECT) of the entities supplied in the entitylist participate, within the boundaries of the supplied domain.

The scope of this query can be limited through supplying a %iKnow.Filters.Filter object for the filter parameter to restrict the result to those CCs occurring in any source satisfying the filter criteria. When using a filter, the filtermode parameter will control whether or not the frequency and spread of returned records should be recalculated and whether results should be resorted along these recalculated numbers.

Specifying a value for positionstomatch will limit the result to those CCs in which the supplied entities are on the Head (with positionstomatch = $$$USEPOSH) or Tail (with positionstomatch = $$$USEPOST) side rather than either of the two (with positionstomatch = $$$USEPOSHT, default setting).

If stemming is enabled for this domain through $$$IKPSTEMMING, CCs containing any actual form of the entities in entityList will be returned. Use pActualFormOnly=1 to retrieve only those CCs containing the actual forms in entitylist. This argument is ignored if stemming is not enabled.

classmethod GetByEntityIds(ByRef result, domainid As %Integer, entityidlist As %List, page As %Integer = 1, pagesize As %Integer = 10, filter As %iKnow.Filters.Filter = "", filtermode As %Integer = $$$FILTERONLY, positionstomatch As %Integer = $$$USEPOSHT, sorttype As %Integer = $$$SORTBYDOMAINDEFAULT, pActualFormOnly As %Boolean = 0) as %Status

This method looks up CCs based on a list of Entity IDs.

See also GetByEntities() for a description of the parameters.

classmethod GetCountByEntities(domainid As %Integer, entitylist As %List, filter As %iKnow.Filters.Filter = "", positionstomatch As %Integer = $$$USEPOSHT, Output sc As %Status = $$$OK, pActualFormOnly As %Boolean = 0) as %Integer

This method returns the number of CC pairs based on a list of entities.

See also GetByEntities() for a description of the parameters.

classmethod GetCountByEntityIds(domainid As %Integer, entityidlist As %List, filter As %iKnow.Filters.Filter = "", positionstomatch As %Integer = $$$USEPOSHT, Output sc As %Status = $$$OK, pActualFormOnly As %Boolean = 0) as %Integer

This method returns the number of CC pairs based on a list of entity ids.

See also GetByEntities() for a description of the parameters.

classmethod GetCountBySource(domainid As %Integer, sourceidlist As %List, setop As %Integer = $$$UNION, Output sc As %Status = $$$OK) as %Integer

Returns the total number of unique CCs appearing in either (if setop = $$$UNION) or all (if setop = $$$INTERSECT) of the sources specified by ID in sourceidlist.

To get the unique CCs of a virtual source, only a single virtual source can be supplied using its negative ID value (otherwise, -1 is returned).

classmethod GetFrequency(domainId As %Integer, ccUniId As %Integer, vSrcId As %Integer = 0, filter As %iKnow.Filters.Filter = "", Output sc As %Status = $$$OK) as %Integer

Returns the frequency of the CC corresponding to the supplied crcUniId.

When specifying a Virtual Source ID, the frequency within the virtual source will be returned.

classmethod GetId(pDomainId As %Integer, pHead As %String, pTail As %String, vSrcId As %Integer = 0, Output pSC As %Status = $$$OK) as %Integer

Returns, if any, the CC ID for the combination of head and tail specified.

When specifying a Virtual Source ID, it will treat the heads and tails as virtual entities, in the context of that vSrcId.

classmethod GetInverse(domainId As %Integer, ccUniId As %Integer, Output sc As %Status = $$$OK) as %Integer
Returns the "inverse" of a CC pair, which means the CC composed of the same head and tail entity, but at inverted positions.
classmethod GetSpread(domainId As %Integer, ccUniId As %Integer, filter As %iKnow.Filters.Filter = "", Output sc As %Status = $$$OK) as %Integer

Returns the spread of the CC corresponding to the supplied ccUniId.

classmethod GetValue(pDomainId As %Integer, pCcId As %Integer, vSrcId As %Integer = 0, Output pSC As %Status = $$$OK) as %List

Returns the entity values this CC is composed of.

When specifying a Virtual Source ID, it will treat the ccid as a virtual one, in the context of that vSrcId.
