The basic concepts of information architecture

Introduction Information Architecture was born in the late 90s, based on the classical principles of solid traditional Information Science (mainly from the discipline of the Organization and Representation of Knowledge). 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is Information Architecture In a technical sense, it is a discipline (and at the same time a discipline that deals with structuring, organizing and tagging elements of informational environments to facilitate searching and retrieval of information they contain, this way improving the usefulness and benefit for users. copyright www.brainybetty.com 2006 All Rights Reserved

The Components of Information Architecture of a Web Organisation systems – classifications t that allow to organise and structure the content of the web site Labeling system - define the terms used to name the categories, options and links used on the web with a useful language for users. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

The Components of Information Architecture of a Web Navigation systems - permit to navigate or move through a site to find the information we need; it shows us where we are and where we can go inside the structure of a site Search systems – enable the retrieval of information within the website using tools such as index 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

A Taxonomy of Web Searches Andrei Broder assumes that web searches are motivated by an information need. Since websites, blogs, and searching tools transform information platform the search engines need to deal with all type of web queries 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

A Taxonomy of Web Searches There are 3 types of web queries based on their intent Navigational – the immediate intent is to reach a particular site Informational – The intent is to acquire some information assumed to be presented on one or more web pages Transactional – The intent is to perform some web-mediated activity 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

The Idea behind these searching engines is to satisfy users needs Some web sites provide logical structures that help us find answers and complete tasks. Others lack any intelligible organization and frustrate our attempts to navigate through them. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

The classic model for information retrieval The classic model of information retrieval (IR) used in information science research can be characterized as follows 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

This model has been very productive and has promoted information retrieval in many ways However it represents some searches but not all, and it has many limitations It is a single query presented by the user, matched to the database contents, yielding a single output. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

BerryPicking Search The query is satisfied not by a single final retrieved set, but by a series of selections of individual references and bits of information at each stage of the ever-modifying search. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Classical vs. BerryPicking Search The focus of the classic model is the match between the document and query representations. The focus of BerryPicking is the sequence of searcher behaviors. The information is being produced from the search at many points along the way 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Classical vs. BerryPicking Search Thus, we can see that this model differs from the classic one in the first two respects: 1) The nature of the query is an evolving one, rather than single and unchanging, 2) the nature of the search process is such that it follows a berrypicking pattern, instead of leading to a single best retrieved set. copyright www.brainybetty.com 2006 All Rights Reserved

Three Circles of Information Architecture The concept of an "information ecology“ is composed of users, content, and context to address the complex dependencies that exist Venn diagram was drawn to help to visualize and understand these relationships. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Three Circles of Information Architecture The three circles illustrate the interdependent nature of users, content, and context within a complex, adaptive information ecology. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Three Circles of Information Architecture Context – Business goals, funding, polices, technology Content – document/data type, content structure Users – Information seeking behaviour 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Key Information Architecture Concepts The goal of effective information architecture (IA) is to make the products, services and information on website easy to find 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Key Information Architecture Concepts Four fundamental skills that information architects have are: Labelling, Structuring, Organization Finding and Managing Categorization and Prioritization Art and Science 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Labelling, Structuring, Organization It's what information architects do best. Structuring involves determining the appropriate levels of granularity for the information "atoms" in your site, and deciding how to relate them to one another. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Labelling, Structuring, Organization Organizing involves grouping those components into meaningful and distinctive categories. Labelling means figuring out what to call those categories and the series of navigation links that lead to them. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Finding and Managing Findability is a critical success factor for overall usability. If users can't find what they need through some combination of browsing, searching, and asking, then the site fails. But user-centered design isn't enough. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Finding and Managing The organizations and people who manage information are important, too. An information architecture must balance the needs of users with the goals of the business. Efficient content management and clear policies and procedures are essential. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Categorization and Prioritization All sites need a primary hierarchal structure, or a primary taxonomy , which ultimately becomes primary navigation on the website. A taxonomy provides guidelines for site navigation, even though the taxonomy itself is not website navigation. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Categorization and Prioritization Without a primary hierarchical structure, orientation is difficult. And users/searchers will not have a sense of beginning or ending when they try to find, and ultimately view, their desired content. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Categorization and Prioritization If the navigation system contains too many links and is too wordy, then navigation is difficult to scan, making desired content less findable. Likewise, if page content has too many embedded text links, then content becomes difficult to read, and the very information piece that a searcher desires becomes more difficult to find. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Art and Science Disciplines such as usability engineering and ethnography are helping to bring the rigor of the scientific method to the analysis of users' needs and information-seeking behaviors. One can study patterns of usage and subsequently make improvements to the web sites. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is not Information Architecture Graphic design is NOT information architecture. Software development is NOT information architecture. Usability engineering is NOT information architecture. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is not Information Architecture Graphic design is a all aspects of visual communication, from the design of corporate logos and identities to layout of individual pages Software development and information architecture, are two fields highly interdependent. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is not Information Architecture Information architects rely on developers to bring ideas to fruition. Developers help us understand what is and isn't possible. And as the Web continues to blur the these collaborations will become even more important. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is not Information Architecture Content management and information architecture are really two sides of the same coin. IA portrays a "snapshot" or spatial view of an information system, while CM describes a temporal view by showing how information should flow into, around, and out of that same system over time. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is not Information Architecture Knowledge management - Knowledge managers develop tools, policies, and incentives to encourage people to share what they know. Information architects focus more on making accessible what has already been captured. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

What is not Information Architecture Usability engineering - Usability engineers understand how to apply the rigors of the scientific method to user research, testing, and analysis. They are often concerned with testing all aspects of the user experience, inclusive of information architecture and graphic design. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Who can be Information Architecture? Graphic design and information design - both graphic design and information design involve much more than creating pretty pictures. These professions are geared more toward creating relationships between visual elements and determining how those elements can be integrated as a whole to communicate more effectively. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Who can be Information Architecture? Information and Library science - Librarians have a long history of organizing and providing access to information and are trained to work with searching, browsing, and indexing technologies. Forward-looking librarians understand that their expertise applies in new arenas far beyond the library walls. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Who can be Information Architecture? Journalists, usability engineers –they are experts at testing and evaluating how people work with systems. Marketing specialists are experts at understanding audiences and communicating messages effectively. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Who can be Information Architecture? Computer science - Programmers and software developers bring important skills and sensitivities to information architecture, especially to "bottom-up" processes. They're also great at figuring out how all component systems and technologies of an information architecture fit together. 15/07/10 copyright www.brainybetty.com 2006 All Rights Reserved

Conclusion In short, we need to understand the business goals behind the web site and the resources available for design and implementation. We need to be aware of the nature and volume of content that exists today and how that might change a year from now. copyright www.brainybetty.com 2006 All Rights Reserved

Conclusion And we must learn about the needs and information-seeking behaviors of our major audiences. Good information architecture design is informed by all three areas. Information architectures must be uniquely matched to their contexts. The vocabulary and structure of your web site and your intranet is a major component of the evolving conversation between your business and your customers and employees. copyright www.brainybetty.com 2006 All Rights Reserved
