Information architecture (IA) is the structural design of shared information environments; the art and science of organizing and labelling websites, intranets, online communities and software to support usability and findability; and an emerging community of practice focused on bringing principles of design and architecture to the digital landscape.〔.〕 Typically, it involves a model or concept of information that is used and applied to activities which require explicit details of complex information systems. These activities include library systems and database development. Information architecture is considered to have been founded by Richard Saul Wurman.〔(【引用サイトリンク】url=http://wurman.com/rsw/ )〕 Today there is a growing network of active IA specialists who constitute the Information Architecture Institute.〔.〕 ==Definition== ''Information architecture'' has somewhat different meanings in different branches of IS or IT: # The structural design of shared information environments. # The art and science of organizing and labeling web sites, intranets, online communities, and software to support findability and usability.〔 # An emerging community of practice focused on bringing principles of design and architecture to the digital landscape.〔Resmini, A. & Rosati, L.

In the field of systems design, for example, information architecture is a component of enterprise architecture that deals with the information component when describing the structure of an enterprise. While the definition of information architecture is relatively well-established in the field of systems design, it is much more debatable within the context of online information systems (i.e., websites). Andrew Dillon refers to the latter as the "big IA-little IA debate".〔.〕 In the little IA view, information architecture is essentially the application of information science to web design which considers, for example, issues of classification and information retrieval. In the big IA view, information architecture involves more than just the organization of a website; it also factors in user experience, thereby considering usability issues of information design. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「information architecture」の詳細全文を読む スポンサード リンク
