| Navigational taxonomies |
Used in top-down organization structures, they refer to the organization of information categories with a view to facilitating navigation and information discovery. These categories, for example, are usually organized in menus or the body of webpages, in the communities and collections of repositories, or in the captions used to describe the subjects on library shelves, previously organized from a classification system. According to Aquino, Carlan, and Brascher (2009), navigational taxonomies must be supported in the following aspects: coherent categorization of matters relative to the understanding of subjects; terminological control to reduce ambiguity; hierarchical relationship between terms; multidimensionality, allowing a given term to be associated with more than one category according to the context of use. |
| Terminological control instruments |
Comprise controlled vocabularies, such as thesauri and ontologies, to support the representation of informational resources. |
| Folksonomies |
They are related to the social organization of information and provide the subject with the classification of informational resources and finding information through navigation (a tag cloud, for example) or search engines, expanding the possibilities of access. They are used in bottom-up organization structures. When associated with controlled vocabularies and semantic technologies, they enhance the possibilities of Information Findability. |
| Metadata |
Comprise the representation of informational resources and are stored in databases for information retrieval purposes. |
| Mediation of computer scientists |
Associated with the development of systems, devices, databases, and interfaces with the use of computational languages, with a view to the management and retrieval of information. |
| Mediation of information professionals |
Occurs in informational environments in which there are institutional subjects involved in the selection, structuring, and dissemination of information. |
| Mediation of informational subjects |
Related to the info-communication actions that informational subjects undertake in any information systems and environments, for example, concerning the production and organization of information and knowledge in collaborative environments, generated from their knowledge, behavior, and competencies that characterize their Intentionality. |
|
Affordances
|
They function as incentives and clues that objects have and provide subjects with the performance of specific actions in the interface of the environment. These actions are related to orientation, location, findability, access, and discovery of information, among others. |
|
Wayfinding
|
Associated with spatial orientation, using aspects that facilitate the localization, findability, and discovery of information through navigation in the interface of the environment. |
| Information discovery |
It is conditioned to the other Information Findability Attributes concerning the facilities that the interface (navigation or search engines) offers to find the information appropriate to the informational needs of the subject, as well as to possible background informational needs. |
| Accessibility and Usability |
Related to the ability of the system to allow equitable access to information (accessibility) within the scope of the target audience established in a project with inherent facilities for the use of the interface (usability). |
| Intentionality |
The theory of Intentionality underlies the importance of emphasizing the experiences and skills of informational subjects in designing information environments and systems. |
| Mobility, Convergence, and Ubiquity |
Associated with the natural environment, external to information systems and environments, but which include them, dynamizing them and enhancing the possibilities of subjects in finding information through different devices and in different contexts and situations. |
