Abstract: A method comprises identifying a candidate entity for matching with one or more target entities from a plurality of target entities, and for one or more of the target entities: determining a target suitability measure indicative of a suitability of the target entity to the candidate entity based on desired target entity attributes of the candidate entity and corresponding one or more target entity attributes associated with the target entity; determining a candidate suitability measure indicative of a suitability of the candidate entity to the target entity based on one or more desired candidate entity attributes of the target entity and corresponding one or more candidate entity attributes associated with the candidate entity; determining a matching score for the candidate entity and target entity pair as a first function of the target suitability measure and the candidate suitability measure; and. determining suggested target entities for matching with the candidate entity.

Abstract: A computer-implemented method for determining entity characteristics. The method comprising: determining a numerical representation of each of a plurality of second entities, each numerical representation comprising a multi-dimensional vector characteristic of the respective second entity, wherein each second entity is associated with one or more first entities; reducing the dimensionality of the numerical representations to produce a plurality of reduced dimensionality numerical representations; and determining a specialisation of each of the plurality of first entities based on the respective reduced dimensionality numerical representations.
