Abstract: Disclosed are a method, a device, and/or a system of efficient determination of a data entity storing healthcare data through mapped entry and/or traversal of a semantic data structure. In one embodiment, a method includes generating an entry criteria data for calculation of an entry point into one or more semantic data structure nodes. The semantic data structure is queried to receive unique identifiers of a plurality of data entities. A tag data matching the entry criteria is mapped from a term value of a medical taxonomy. The plurality of data entities includes a service profile, a professional profile, and/or a technology profile. A card data for each data entity associated with the unique identifiers is transmitted to a client device. A profile request may be generated and the semantic data structure traversed for related data entities to increase probability of connection to a solution profile applicable to the user.
