Taxonomy terms should be understood by all sets of users, and all users should have the same understanding of what the terms mean. However, creating terms that serve the business objectives of building a taxonomy and enable more than one type of users is a challenge.
A taxonomy may have more than one type of user. For example, health information end-users include both healthcare providers and patients or their family members. Therefore, it is important that in this case, all types of end-users should have the same understanding of what a term means. To this end, it is important to understand the users’ perspective and the terms they are likely to use to describe the concepts. That is why user research is a significant part of taxonomy design.
Also, an enterprise may have an internal taxonomy to facilitate greater precision in retrieval results and an external taxonomy to support superior recall. It follows that the taxonomies serve diverse audiences and users and though they are connected, the two taxonomies will have different terms for the same concept and diverse structures. Here, the use of taxonomy features of polyhierarchy and non-preferred terms can support diverse users with different vocabularies, perspectives, and approaches to find their way to the desired content.
