Metadata for the Masses
'But what if we could somehow peek inside our users’ thought processes to figure out how they view the world? One way to do that is through ethnoclassification [1] — how people classify and categorize the world around them.' [Peter Merholz/Adaptive Path 10/2004]

Schrijf een recensie | Voeg to aan del.icio.us A simplified model for facet analysis
The purpose of this study is to propose a simplified model for facet analysis that incorporates the principles of facet analysis proposed by both Ranganathan and the CRG. The purpose of this simplified model is to act primarily as a teaching tool to introduce LIS students to a consolidated, and hopefully easy-to-read, classification model that will enable them to understand how faceted classification systems are designed and how they work.

Schrijf een recensie | Voeg to aan del.icio.us Bookmark, Classify and Share: A mini-ethnography of social practices in a distributed classification
Working within the constraints of a very limited data sample, this study attempts to identify some of the information management and meaning construction practices of an online distributed classification (a.k.a. free tagging or ethnoclassification) community. Specifically, this study seeks to investigate the social and communicative practices that emerge when users are encouraged to share web links with one another by using a metadata keyword, or tag, to demark a social group, apart from using other tags to classify links according to an emergent taxonomy.

Schrijf een recensie | Voeg to aan del.icio.us Extended Faceted Taxonomies for Web Catalogs
Our approach can be used for developing Web catalogues that offer complete navigation trees, require less storage space, and are more comprehensive and scalable. Furthermore, taxonomies designed according to our approach can be integrated or articulated more easily than hierarchical ones. Further research includes extending this approach to define an algebraic system for taxonomies with operators that allow the specification of valid compound terms using both positive and negative sets of compound terms.

Schrijf een recensie | Voeg to aan del.icio.us Extracting Value from Automated Classification Tools
Automated classification tools can't solve today's large-scale web and intranet indexing challenges alone. Neither can humans. But solutions that integrate human expertise with software products such as Interwoven's Metatagger and Autonomy's Categorizer can provide real value and savings. After a brief introduction to automated classification, this white paper discusses the benefits and limitations of manual, automated, and hybrid approaches. It explores the opportunities for leveraging controlled vocabularies and thesauri to produce more effective indexing solutions. [ACIA 03/2001]

Schrijf een recensie | Voeg to aan del.icio.us Fighting (with) Hierarchies - Part I: Basics
Despite this ubiquity, many users are not as experienced with hierarchies as some developers might believe; in general people have problems understanding and using hierarchies, which are essentially an abstract notion and not a "real life" object. In this series, I
want to shed some light on the problems users have with hierarchies and also discuss their various uses and presentations in the software
world. [SAP Design Guild 2001]

Schrijf een recensie | Voeg to aan del.icio.us Flexible Search and Navigation using Faceted Metadata
We have developed an innovative search interface that allows non-expert users to move through large information spaces in a flexible manner without feeling lost. The design goal was to offer users a “browsing the shelves” experience seamlessly integrated with focused search. Key to achieving our goal is the explicit exposure of hierarchical faceted metadata in a manner that is intuitive and inviting to users. After several iterations of design and testing, the usability results are strikingly positive. We believe our approach marks a major step forward in search user interfaces and can serve as a model for web-based collections of up to 100,000 items.

Schrijf een recensie | Voeg to aan del.icio.us How to Make a Faceted Classification and Put It On the Web
This paper will attempt to bridge the gap by giving procedures and advice on all the steps involved in making a faceted classification and putting it on the web. Web people will benefit by having a rigorous seven-step process to follow for creating faceted classifications, and librarians will benefit by understanding how to store such a classification on a computer and make it available on the web. The paper is meant for both webmasters and information architects who do not know a lot about library and information science, and librarians who do not know a lot about building databases and web sites.

Schrijf een recensie | Voeg to aan del.icio.us Immersed in Structure: The Meaning and Function of Taxonomies
Organizational structures within Web sites encourage emotional, fortuitous information-seeking behavior. Directories are value-laden tools of information organization that articulate a specific world-view. Because taxonomies lay out synonymous, associative and hierarchical relationships, they function like guides to information. They support the dynamic process of finding information and facilitate associative thought.

Schrijf een recensie | Voeg to aan del.icio.us Looking for Metadata in All the Wrong Places
What if you were considering purchasing a sports jacket and didn't know to look for the term "blazers"? That's where a thesaurus can help. Think of a thesaurus as a CV on steroids. Besides a CV's preferred terms, a thesaurus can include variant terms (like "sports jackets"). The relationship between preferred and variant terms can be leveraged to improve searching: users who enter "sports jackets" would retrieve items indexed under "blazers." Thesauri can also include broader terms (e.g., "casual clothing"), narrower terms (e.g., "silk blazers"), related terms (e.g., "shirts"), and scope notes, which may define and provide context for the preferred term.

Schrijf een recensie | Voeg to aan del.icio.us Ontologies Come of Age
Ontologies have moved beyond the domains of library science, philosophy, and knowledge representation. They are now the concerns of marketing departments, CEOs, and mainstream business. Research analyst companies such as Forrester Research report on the critical roles of ontologies in support of browsing and search for e-commerce and in support of interoperability for facilitation of knowledge management and configuration. One now sees ontologies used as central controlled vocabularies that are integrated into catalogues, databases, web publications, knowledge management applications, etc. Large ontologies are essential components in many online applications including search (such as Yahoo and Lycos), e-commerce (such as Amazon and eBay), configuration (such as Dell and PC-Order), etc. One also sees ontologies that have long life spans, sometimes in multiple projects (such as UMLS, SIC codes, etc.). Such diverse usage generates many implications for ontology environments. In this paper, we will discuss ontologies and requirements in their current instantiations on the web today. We will describe some desirable properties of ontologies. We will also discuss how both simple and complex ontologies are being and may be used to support varied applications. We will conclude with a discussion of emerging trends in ontologies and their environments and briefly mention our evolving ontology evolution environment. [Deborah L.

Schrijf een recensie | Voeg to aan del.icio.us Taxonomies and Topic Maps: Categorization Steps Forward
Happily, categorization technologies seem to have matured to the point where they can be useful to more and more publishers. Increasingly, Web publishers are investing in both the technologies to categorize content and the labor associated with implementing the technology. And looming on the horizon are "topic maps," an intriguing approach to tagging data for categories, especially for collections of data as opposed to singular documents. [eContent 08/2001]

Schrijf een recensie | Voeg to aan del.icio.us Ten taxonomy myths
Taxonomies have recently emerged from the quiet backwaters of biology, book indexing, and library science into the corporate limelight. They are supposed to be the silver bullets that will help users find the needle in the intranet haystack, reduce "friction" in electronic commerce, facilitate scientific research, and promote global collaboration. But before this can happen, practitioners need to dispel the myths and confusion, created in part by the multi-disciplinary nature of the task and the hype surrounding content management technologies.

Even using a relatively primitive taxonomic system, Microsoft reported a 40% improvement in hit rates. Satisfaction metrics doubled. In addition, the time spent trying to find a given document was significantly reduced. The success rate of taxonomic-based searching reduces the strain on systems and on the people who use them.
