Abstract

Folksonomy is the result of describing Web resources with tags created by Web users. Although it has become a popular application for the description of resources, in general terms Folksonomies are not being conveniently integrated in metadata. However, if the appropriate metadata elements are identified, then further work may be conducted to automatically assign tags to these elements (RDF properties) and use them in Semantic Web applications. This article presents research carried out to continue the project Kinds of Tags, which intends to identify elements required for metadata originating from folksonomies and to propose an application profile for DC Social Tagging. The work provides information that may be used by software applications to assign tags to metadata elements and, therefore, means for tags to be conveniently gathered by metadata interoperability tools. Despite the unquestionably high value of DC and the significance of the already existing properties in DC Terms, the pilot study show revealed a significant number of tags for which no corresponding properties yet existed. A need for new properties, such as Action, Depth, Rate, and Utility was determined. Those potential new properties will have to be validated in a later stage by the DC Social Tagging Community.

Abstract

Many Web sites have begun allowing users to submit items to a collection and tag them with keywords. The folksonomies built from these tags are an interesting topic that has seen little empirical research. This study compared the search information retrieval (IR) performance of folksonomies from social bookmarking Web sites against search engines and subject directories. Thirty-four participants created 103 queries for various information needs. Results from each IR system were collected and participants judged relevance. Folksonomy search results overlapped with those from the other systems, and documents found by both search engines and folksonomies were significantly more likely to be judged relevant than those returned by any single IR system type. The search engines in the study had the highest precision and recall, but the folksonomies fared surprisingly well. Del.icio.us was statistically indistinguishable from the directories in many cases. Overall the directories were more precise than the folksonomies but they had similar recall scores. Better query handling may enhance folksonomy IR performance further. The folksonomies studied were promising, and may be able to improve Web search performance.

Abstract

There is a growing interest into how we represent and share tagging data in collaborative tagging systems. Conventional tags, meaning freely created tags that are not associated with a structured ontology, are not naturally suited for collaborative processes, due to linguistic and grammatical variations, as well as human typing errors. Additionally, tags reflect personal views of the world by individual users, and are not normalised for synonymy, morphology or any other mapping. Our view is that the conventional approach provides very limited semantic value for collaboration. Moreover, in cases where there is some semantic value, automatically sharing semantics via computer manipulations is extremely problematic. This paper explores these problems by discussing approaches for collaborative tagging activities at a semantic level, and presenting conceptual models for collaborative tagging activities and folksonomies. We present criteria for the comparison of existing tag ontologies and discuss their strengths and weaknesses in relation to these criteria.

"Irgendwann ist es einfach zu viel Information. Einmal "Schokolade" bei Google eingeben und mal eben 9 870 000 Links zur Auswahl. "Pilgern - 800 000 Einträge. 21400 000 für "Hörbuch. Die Auswahl fällt schwer, und wer hat schon die Geduld, sich alle Seiten anzugucken. Am besten wäre es, irgendjemand könnte eine der, vielen Seiten empfehlen. Auf eben dieses Prinzip setzen immer mehr Internet-Seiten. Seiten wie www.mister-wong.de bestehen nur aus Empfehlungen von Nutzern für Nutzer. Immerhin vier empfehlen die Webseite zum Pralinenclub, acht Nutzer haben sich für www.theobroma-cacao.de ein Lesezeichen angelegt, beim Pilgern sind sich auch gleich einige Benutzer einig, welche Seite sie am liebsten zum Thema lesen und empfehlen. "Social bookmarks" - Lesezeichen, die man anderen zur Verfügung stellt - sind vor allem auf englischsprachigen Seiten zu finden. Mit Anbietern wie "Mister Wong" oder "Netselektor" können jetzt auch die Deutschen ihre Lieblingslesezeichen im Internet mit anderen teilen. "Bei den großen Suchmaschinen haben es gute Seiten oft schwer: Wenn sie nicht bei Yahoo oder Google nach der Suchanfrage ganz oben stehen, findet sie niemand", sagt "Mister Wong"Pressesprecher Christian Clawien. Für ihn ist das Konzept der "Social bookmarks" die ideale Alternative zur mechanischen Suchmaschine. Noch sind die Zahlen der Aktiven aber gering. 1,3 Millionen abgespeicherte Bookmarks verzeichnet "Mister Wong" seit der Gründung im März 2006. Vor allem Leute, die sowieso bereits einen guten Draht zum Internet haben, nutzten das Angebot, sagt Clawien. Langsam beginnt die Phase, wo Monetarisierung möglich ist." Langfristig soll auch Werbung auf der Seite erscheinen. Bei "www.netselektor.de", im November 2006 gegründet, sitzt zudem noch eine Redaktion vor dem Computer, die die abgelegten Lesezeichen der Nutzer durchforstet und die besten Empfehlungen noch mal als qualitativ hochwertig vorstellt. Nach und nach soll so in Zusammenarbeit mit den Usern ein "Best-of-Internet" entstehen. Natürlich nur mit den Internet-Juwelen, die einer Empfehlung würdig sind. Allerdings erreichen die "Social bookmark"-Seiten auch schnell ihre Grenzen: Nicht alle Stichworte bringen Ergebnisse, nicht immer sind die Vorlieben der Nutzer für Internet-Seiten nachvollziehbar, und noch reicht auch nicht die Anzahl der beteiligten Nutzer, um tatsächlich all die verborgenen Juwelen im riesigen weltweiten Netz zutage zu fördern. Originelles gibt es aber trotzdem schon jetzt - vom Karaoke Trainer bis zu www.dontclick.it", die Seite, die ohne Maus funktionieren soll."

Abstract

This paper develops an ethical conception of library labor as an intellectual craft that can serve as an alternative to a deterministic discourse of technological transformation. In this paper, the author proposes a model of librarianship as an intellectual craft that can be used as an "ideal type" in comparison to recent transformations in the practice of librarianship. This paper then examines the rise of participatory classification in the realm of leisure in user-generated classification schemes (e.g., folksonomies) as a way of examining some of the difficult ethical questions that this ideal of intellectual craft poses when applied to contemporary conditions. Marx's concept of surplus value is used to examine how donated labor adds to the general knowledge. This paper concludes by advocating for the general expansion of leisure coupled with the promotion public institutions that support the craft of those who organize information in a broadly defined public interest. In an era of dramatic change, such a framework offers a positive ethical account of librarians and information professionals' labor that is not wholly dependent on a discourse of market exchange.

Abstract

Principles, justifications and their subjective nature are central issues of knowledge organisation research and practice. This study discusses folksonomies a source of aesthetic judgments and whether those judgments can provide justification for knowledge organisation. Using Flickr photosharing service as an example, the folksonomies are examined as potential source of collective judgments of a larger group of people with a special focus on everyday life aesthetics. The study is based on a visual analysis of clusters of photographs formed by Flickr with a set of common aesthetic adjectives.

Abstract

An increasingly difficult challenge in social tagging applications is negotiating the number of existing tags. This article examines the use of facets to facilitate the efficient organization and browsing of tags into manageable and distinct categories. Current and proposed methodologies for the application of facets in social tagging applications are evaluated. Results of this analysis indicate that these methodologies provide insufficient guidelines for the choice, evaluation, and maintenance of the facets. Suggestions are made to guide the design of a more rigorous methodology for the application of facets to social tagging applications.

Abstract

While the organization and representation of information and knowledge have historically been done by professionals, the rise of social media has spread the notion that this can be done more collaboratively. A more collaborative approach would entail a change in the role of professionals and in the goals and values of the systems. This paper explores the notion of authority and the role of professionals in a changing environment where more people participate in the organization and representation of information and knowledge. The paper questions the traditional role of the professionals and argues that systems must be designed to facilitate trust and authority, and that the authority of folksonomies and systems comes from the users' collective interpretations and meaning production.

Abstract

There are close to a billion websites on the Internet with approximately 400 million users worldwide [www.internetworldstats.com]. People go to websites for a wide variety of different information tasks, from finding a restaurant to serious research. Many of the difficulties with searching the Web, as it is structured currently, can be attributed to increases to scale. The content of the Web is now so large that we only have a rough estimate of the number of sites and the range of information is extremely diverse, from blogs and photos to research articles and news videos.

Abstract

Purpose - The purpose of the paper is to provide an overview of the collaborative tagging phenomenon and explore some of the reasons for its emergence. Design/methodology/approach - The paper reviews the related literature and discusses some of the problems associated with, and the potential of, collaborative tagging approaches for knowledge organisation and general resource discovery. A definition of controlled vocabularies is proposed and used to assess the efficacy of collaborative tagging. An exposition of the collaborative tagging model is provided and a review of the major contributions to the tagging literature is presented. Findings - There are numerous difficulties with collaborative tagging systems (e.g. low precision, lack of collocation, etc.) that originate from the absence of properties that characterise controlled vocabularies. However, such systems can not be dismissed. Librarians and information professionals have lessons to learn from the interactive and social aspects exemplified by collaborative tagging systems, as well as their success in engaging users with information management. The future co-existence of controlled vocabularies and collaborative tagging is predicted, with each appropriate for use within distinct information contexts: formal and informal. Research limitations/implications - Librarians and information professional researchers should be playing a leading role in research aimed at assessing the efficacy of collaborative tagging in relation to information storage, organisation, and retrieval, and to influence the future development of collaborative tagging systems. Practical implications - The paper indicates clear areas where digital libraries and repositories could innovate in order to better engage users with information. Originality/value - At time of writing there were no literature reviews summarising the main contributions to the collaborative tagging research or debate.

Abstract

Purpose - The purpose of this paper is to investigate the linking of a folksonomy (user vocabulary) and LCSH (controlled vocabulary) on the basis of word matching, for the potential use of LCSH in bringing order to folksonomies. Design/methodology/approach - A selected sample of a folksonomy from a popular collaborative tagging system, Delicious, was word-matched with LCSH. LCSH was transformed into a tree structure called an LCSH tree for the matching. A close examination was conducted on the characteristics of folksonomies, the overlap of folksonomies with LCSH, and the distribution of folksonomies over the LCSH tree. Findings - The experimental results showed that the total proportion of tags being matched with LC subject headings constituted approximately two-thirds of all tags involved, with an additional 10 percent of the remaining tags having potential matches. A number of barriers for the linking as well as two areas in need of improving the matching are identified and described. Three important tag distribution patterns over the LCSH tree were identified and supported: skewedness, multifacet, and Zipfian-pattern. Research limitations/implications - The results of the study can be adopted for the development of innovative methods of mapping between folksonomy and LCSH, which directly contributes to effective access and retrieval of tagged web resources and to the integration of multiple information repositories based on the two vocabularies. Practical implications - The linking of controlled vocabularies can be applicable to enhance information retrieval capability within collaborative tagging systems as well as across various tagging system information depositories and bibliographic databases. Originality/value - This is among frontier works that examines the potential of linking a folksonomy, extracted from a collaborative tagging system, to an authority-maintained subject heading system. It provides exploratory data to support further advanced mapping methods for linking the two vocabularies.

Abstract

Traditional knowledge organization approaches struggle to make large user-generated collections navigable, especially when these collections are quickly growing, in which currency is of particular concern, for which professional classification design is too costly. Many of these collections use folksonomies for labelling and organization as a low-cost but flawed knowledge organization approach. While several computational approaches offer ways to ameliorate the worst flaws of folksonomies, some user-generated collections have implemented a human judgment-centered alternative to produce structured folksonomies. An analysis of three such implementations reveals design differences within the space. This approach, termed "curated folksonomy," presents a new object of study for knowledge organization and represents one answer to the tension between scalability and the value of human judgment.

Abstract

The subject of this article is folksonomies on the Internet. One of the largest folksonomies on the Internet in terms of number of users and tagged websites is the computer program del.icio.us, where more than 100,000 people have tagged the websites that they and others find using their own keywords. How this is done in practice and the patterns to be found are the focus of this article. The empirical basis is the collection of 76,601 different keywords with a total frequency of 178,215 from 500 randomly chosen taggers on del.icio.us at the end of 2005. The keywords collected were then analyzed quantitatively statistically by uncovering their frequency and percentage distribution and through a statistical correspondence analysis in order to uncover possible patterns in the users' tags. Subsequently, a qualitative textual analysis of the tags was made in order to find out by analysis which tagging strategies are represented in the data material. This led to four conclusions. 1) the distribution of keywords follows classic power law; 2) distinct tagging communities are identifiable; 3) the most frequently used tags are situated on a general-specific axis; and 4) nine distinct tagging strategies are observed. These four conclusions are put into perspective collectively in respect of a number of more general and theoretical considerations concerning folksonomies and the classification systems of the future.

Abstract

This paper proposes a conceptual framework to recast a folksonomy as a Web classification and to use this to explore the ways in which people work with it in assessing, sharing, and navigating Web resources. The author uses information scent and foraging theory as a context to discuss how folksonomy is constructed through interactions among users, a folksonomic system, and a given domain that consists of a group of users who share the same interest or goals. The discussion centers on two dimensions of folksonomies: (1) folksonomy as a Web classification which puts like information together in a Web context; and (2) folksonomy as information scent which helps users to find related resources and users, and obtain desired information. This paper aims to integrate these two dimensions with a conceptual framework that addresses the structure of a folksonomy shaped by users' interactions. A proposed framework consists of three components of users' interactions with a folksonomy: (a) tagging - cognitive categorization of Web accessible resources by an individual user; (b) navigation - exploration and discovery of Web accessible resources in the folksonomic system; and (c) knowledge sharing - representation and communication of knowledge within a domain. This understanding will help us motivate possible future directions of research in folksonomy. This initial framework will frame a number of research questions and help lay the groundwork for future empirical research which focuses on qualitative analysis of a folksonomy and users' tagging behaviors.

Abstract

Catalogers have always had to balance adherence to cataloging rules and authority files with creating cataloging that is current and relevant to users. That dilemma has been complicated in new ways because of user demands in the world of Web 2.0. Standardized cataloging is crucial for communication between computer systems, but patrons now have an expectation of social interaction on the Internet, as evidenced by the popularity of folksonomy. After a description of traditional subject cataloging and folksonomy, this article discusses several institutions where subject cataloging is still used, but where patron interaction is also encouraged. User-generated tags can coexist with controlled vocabulary such as subject headings.

Abstract

This article examines tagging as knowledge organization. Tagging is a kind of indexing, a process of labelling and categorizing information made to support resource discovery for users. Social tagging generally means the practice whereby internet users generate keywords to describe, categorise or comment on digital content. The value of tagging comes when social tags within a collection are aggregated and shared through a folksonomy. This article examines definitions of tagging and folksonomy, and discusses the functions, advantages and disadvantages of tagging systems in relation to knowledge organization before discussing studies that have compared tagging and conventional library-based knowledge organization systems. Approaches to disciplining tagging practice are examined and tagger motivation discussed. Finally, the article outlines current research fronts.

Abstract

The field of subject analysis enjoyed a flurry of interest in the 1970s, and has recently become a focus of attention again. The scholarly community doing work in this area has become more diffuse, and has grown to include new groups, such as information architects. Changes in information services and information seeking have led to reexamination of the nature and role of subject analysis tools and practices. This selective review looks at thesauri, guided navigation, and folksonomy as three activity areas in which subject analysis researchers have been attempting to address rapidly changing new environments.

Abstract

Documentation of art museum collections has been traditionally written by and for art historians. To make art museum collections broadly accessible, and to enable art museums to engage their communities, means of access need to reflect the perspectives of other groups and communities. Social Tagging (the collective assignment of keywords to resources) and its resulting Folksonomy (the assemblage of concepts expressed in such a cooperatively developed system of classification) offer ways for art museums to engage with their communities and to understand what users of online museum collections see as important. Proof of Concept studies at The Metropolitan Museum of Art compared terms assigned by trained cataloguers and untrained cataloguers to existing museum documentation, and explored the potential for social tagging to improve access to museum collections. These preliminary studies, the results of which are reported here, have shown the potential of social tagging and folksonomy to open museum collections to new, more personal meanings. Untrained cataloguers identified content elements not described in formal museum documentation. Results from these tests - the first in the domain - provided validation for exploring social tagging and folksonomy as an access strategy within The Metropolitan Museum, motivation to proceed with a broader inter-institutional collaboration, and input into the development of a multi-institutional collaboration exploring tagging in art museums. Tags assigned by users might help bridge the semantic gap between the professional discourse of the curator and the popular language of the museum visitor. The steve collaboration (http://www.steve.museum) is building on these early studies to develop shared tools and research methods that enable social tagging of art museum collections and explore the utility of folksonomy for providing enhanced access to collections.

Abstract

The essence of folksonomies is user-created descriptive metadata as opposed to the traditional sender-determined descriptive metadata in taxonomies and faceted classification. We briefly introduce the beginning and principles of folksonomy and discuss the categorizing concept of folksonomies on the basis of the computer program del.icio.us. The selection of the metadata tagged is not accidental, rather tagging follows a pattern that proves to be the pattern for the classic power law, which, in many complex systems is seen to unfold as an imitation-dynamic that creates an asymmetry, where a few descriptive metadata are often reproduced and the majority seldom reproduced. In del.icio.us, it is the very broad and basic subject headings that are often reproduced and achieve power in the system - which in cognitive psychology is called cognitive basic categories - while the small, more specific subject headings are seldom reproduced. The law of power's underlying imitation-dynamic in del.icio.us is explained from the perspective of different theoretical paradigms, i.e. network, economy and cognition. The theorectical and speculative conclusion is that the law of power and asymmetry is biased by a cognitive economizing through a simplification principle in the users construction of descriptive metadata. Free tagging in folksonomies is comparable to empirical experiments in free categorization. Users often choose broad basic categories, because that requires the least cognitive effort. The consequences are that folksonomy is not necessarily a better, more realistic and cheaper method of creating metadata than that which can be generated through taxonomies, faceted classification or search algorithms. Folksonomy as a self-organizing system likely cannot create better and cheaper descriptive metadata.

Abstract

Services in Web 2.0 generate a large quantity of information, distributed over a range of resources (e.g. photos, URLs, videos) and integrated into different platforms (e.g. social bookmarking systems, sharing platforms (Peters, 2009). To adequately use this mass of information and to extract it from the platforms, users must be equipped with suitable tools and knowledge. After all, the best information is useless if users cannot find it: 'The model of information consumption relies on the information being found' (Vander Wal, 2004). In Web 2.0, the retrieval component has been established through so-called folksonomies (Vander Wal, 2005a), which are considered as several combinations of an information resource, one or more freely chosen keywords ('tags') and a user. Web 2.0 services that use folksonomies as an indexing and retrieval tool are defined as 'collaborative information services' because they allow for the collaborative creation of a public database that is accessible to all users (registered, where necessary) via the tags of the folksonomy (Ding et al., 2009; Heymann, Paepcke and Garcia-Molina, 2010).
