The following are draft DSIA definitions that disambiguate the term “information architecture” as it applies to the application user interface function. These definitions are based on working theory and research in information science by Nathaniel Davis.

Information Architecture (Web Practice)
Information architecture is a practice that defines and maintains the models for concepts, content and contextual factors that influence sustainable human interaction with technology. In other words, information architecture provides the conceptual “blueprint” for application user interfaces.
Information architecture is a practice that defines and maintains the models for concepts, content, and contextual factors that influence sustainable human interaction with technology.
When done well, information architecture helps to simplify how people navigate and engage with content presented in application user interfaces or information environment. That means delivering content to users when and how they need it. And doing this requires IA practitioners to produce compelling insight that argues the targeted use of content.
This holistic (or systemic) perspective uniquely situates information architecture as a vital factor for a coherent strategy, design ideation, and software development activities.
Other perspectives to consider:
Information Architecture (Work Product)
The information architecture of an application user interface or system of interfaces functions as the governing framework for content behavior and user engagement. It represents the aggregate of assumptions and governing conceptual constructs for assigning properties and attributes to content, and the endowment and evolution of conceptual and content relationships over time for a given context.

Information architecture is often misunderstood as a tangible design artifact like site navigation, the labeling with which a user might engage in a user interface, or the path that a user might take to navigate to desired content and functionality. In actuality, these are only parts to a greater whole.
The information architecture for an application user interface is a set of structural definitions that correlate to the concept and content constraints of a target environment. IA structural definitions result in diagrams and reference models that are shared with team members to help inform activities that involve strategy, interface design, and software development.
Information Architecture (Science)
Information architecture is a relatively new information science that studies the description and nature of information as a discrete phenomenon. It is interested in the properties and behaviors that information exhibits over time and space.
Information architecture is a … science that studies the description and nature of information as a discrete phenomenon.
Traditional information science investigates information as an entity that can be originated, collected, organized, stored, retrieved, interpreted, transmitted, transformed, and utilized . Information architecture science explores the potential metaphysical, semiotic, linguistic, and ontological impact of information and the systemic information complexity that’s created when coupling human performance and cognition with the spatial topology of one’s inhabited environment.
Insight in information architecture science helps to improve the performance of human-information interaction and knowledge management in complex user interface environments.
