They are typically sent as in-line HTML to browsers. However, display mechanisms suited for ordinary text are not ideal for tags, because font sizes may vary widely on a line. As well, the typical layout does not account for relationships that may be known between tags. This paper presents models and algorithms to improve the display of tag clouds that con- sist of in-line HTML, as well as algorithms that use nested tables to achieve a more general 2-dimensional layout in which tag relationships are considered. The first algorithms leverage prior work in typesetting and rectangle packing, whereas the second group of algorithms leverage prior work in Electronic Design Automation. Experiments show our algorithms can be efficiently implemented and perform well.

Flickr, Delicious, Technorati and many others have all featured a tag cloud at some point in their history. However, it is unclear whether the tag cloud is actually useful as an aid to finding information. We conducted an experiment, giving participants the option of using a tag cloud or a traditional search interface to answer various questions. We found that where the information-seeking task required specific information, participants preferred the search interface. Conversely, where the information-seeking task was more general, participants preferred the tag cloud. While the tag cloud is not without value, it is not sufficient as the sole means of navigation for a folksonomy-based dataset. 10.1177/0165551506078083 The folksonomy tag cloud: When is it useful?

One of the most important approaches to support users in searching and navigating media collections is collaborative filtering. Recently, systems as flickr or last.fm have become popular. They allow users to not only rate but also tag items with arbitrary labels. Such systems replace the concept of a global common ontology, as envisioned by the Semantic Web, with a paradigm of heterogeneous, local “folksonomies”. The problem of such tagging systems is, however, that resulting taggings carry only little semantics. In this paper, we present an extension to the tagging approach. We allow tags to be grouped into aspects. We show that introducing aspects does not only help the user to manage large numbers of tags, but also facilitates data mining in various ways. We exemplify our approach on Nemoz, a distributed media organizer based on tagging and distributed data mining.

Despite their popularity, tag clouds suffer from limitations of separation from tagged items, lack of relational information between tags and a less-than-fully interactive experience. In this paper we introduce Tagscape, a tag system interface that attempts to address these issues. Tagscape uses a magnet analogy to represent relationships between tags and tagged items as attractions and repulsions. Preliminary informal evaluations of the interface were positive and revealed avenues for future work.

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.

This paper examines market share, reliability, performance, scalability, security, and total cost of ownership. It also has sections on non-quantitative issues, unnecessary fears, OSS/FS on the desktop, usage reports, governments and OSS/FS, other sites providing related information, and ends with some conclusions.

These systems give users the opportunity to add data items and to attach their own metadata (or tags) to stored data. The result is an effective content management tool for individual users. Recent studies, however, suggest that, as tagging communities grow, the added content and the metadata become harder to manage due to an ease in content diversity. Thus, mechanisms that cope with increase of diversity are fundamental to improve the scalability and usability of collaborative tagging systems. This paper analyzes whether usage patterns can be harnessed to improve navigability in a growing knowledge space. To this end, it presents a characterization of two collaborative tagging communities that target scientific literature: CiteULike and Bibsonomy. We explore three main directions: First, we analyze the tagging activity distribution across the user population. Second, we define new metrics for similarity in user interest and use these metrics to uncover the structure of the tagging communities we study. The structure we uncover suggests a clear segmentation of interests into a large number of individuals with unique preferences and a core set of users with interspersed interests. Finally, we offer preliminary results that demonstrate that the interest-based structure of the tagging community can be used to facilitate content usage as communities scale.

Simultaneously a debate on the pros and cons of allowing users to add personal keywords to digital content has arisen. A stable category model for social tags on a linguistic as well as functional level is presented, based on data gathered from the scientific bibliography management tool connotea. Also some initial findings of a comparative analysis of social tags and author keywords are reported. Tagging tagging: Analysing user keywords in scientific bibliography management systems.

There has been a flurry of activity in this domain recently with a number of high profile web sites and search engines adopting the practice. They have sparked a great deal of excitement and debate in the popular and technical literature, accompanied by a number of analyses of the statistical properties of tagging behavior. However, none has addressed the deep nature of folksonomies. What is the nature of a tag? Where does it come from? How is it related to a resource? In this paper we present a study in which the linguistic properties of folksonomies reveal them to contain, on the one hand, tags that are similar to standard categories in taxonomies. But on the other hand, they contain additional tags to describe class properties. The implications of the findings for the relationship between folksonomy and ontology are discussed.

We study the temporal evolution of the global vocabulary size, i.e. the number of distinct tags in the entire system, as well as the evolution of local vocabularies, that is the growth of the number of distinct tags used in the context of a given resource or user. In both cases, we find power-law behaviors with exponents smaller than one. Surprisingly, the observed growth behaviors are remarkably regular throughout the entire history of the system and across very different resources being bookmarked. Similar sub-linear laws of growth have been observed in written text, and this qualitative universality calls for an explanation and points in the direction of non-trivial cognitive processes in the complex interaction patterns characterizing collaborative tagging.

Art museums, in their role as curators and interpreters of the cultural record, have developed standards for the description of works of art (such as the Categories for the Description of Works of Art, CDWA) that emphasize the physical nature of art as artefact, the authorial role of the creator, the temporal and cultural context of creation and ownership, and the scholarly significance of the work over time. Collections managers have recorded conservation, exhibition, loan and publication history, along with significant volumes of internal documentation of acquisition and storage, that support the custody and care of artefacts of significant cultural value. But the systems of documentation and classification that support the professional discourse of art history and the management of museum collections have failed to represent the interests, perspectives or passions of those who visit [use?] museum collections, both on-site and online. As museums move to reflect the breadth of their audiences and the diversity of their perspectives, so must museum documentation change to reflect concerns other than the traditionally art historical and museological. Social tagging offers a direct way for museums to learn what museum-goers see in works of art, what they judge as significant and where they find or make meaning. Wi thin the steve collaboration(ht tp://www.steve.museum), a group of art museums is collectively exploring the role of social tagging and studying the resulting folksonomy (Bearman & Trant, 2005; Chun, Cherry, Hiwiller, Trant, & Wyman, 2006; Trant & Wyman, 2006). Analysis of terms collected in the prototype steve tagger suggests that social tagging of art museum objects can in fact augment museum documentation with unique access points not found in traditional cataloguing. Terms collected through social tagging tools are being compared to museum documentation, to establish the actual contributions made by naïve users to the accessibility of art museum collections and to see if social classification provides a way to bridge the semantic gap between art historians and art museums’ publics.

The main goal of our evaluation is to investigate the effect of some of the different properties that can be utilized in presenting tags e.g. alphabetization, using larger fonts etc. We show that a number of these factors can affect the ease with which users can find tags and use the tools for presenting tags to users.

A closer look, though, reveals that the core technologies and concerns of these two approaches are complementary and that each field can and must draw from the other’s strengths. We believe that future web applications will retain the Web 2.0 focus on community and usability, while drawing on Semantic Web infrastructure to facilitate mashup-like information sharing. However, there are several open issues that must be addressed before such applications can become commonplace. In this paper, we outline a semantic weblogs scenario that illustrates the potential for combining Web 2.0 and Semantic Web technologies, while highlighting the unresolved issues that impede its realization. Nevertheless, we believe that the scenario can be realized in the short-term. We point to recent progress made in resolving each of the issues as well as future research directions for each of the communities.

Free form metadata or tags, as used in social bookmarking and folksonomies, have become more and more popular and successful. Such tags are relevant keywords associated with or assigned to a piece of information (e.g., a Web page), describing the item and enabling keyword-based classification. In this paper we propose P-TAG, a method which automatically generates personalized tags for Web pages. Upon browsing a Web page, P-TAG produces keywords relevant both to its textual content, but also to the data residing on the surfer’s Desktop, thus expressing a personalized viewpoint. Empirical evaluations with several algorithms pursuing this approach showed very promising results. We are therefore very confident that such a user oriented automatic tagging approach can provide large scale personalized metadata annotations as an important step towards realizing the Semantic Web.

People use a variety of sites to tag photos, websites, blogs, and videos. Recently, commercial websites such as Amazon.com, have also implemented tagging on their websites. This type of tagging is not only social, where users can view other’s tags and resources, but collective or collaborative, where any user can tag any resource. By analyzing the tags of two sites that implement free-for-all tagging - Amazon.com and Last.fm - this paper describes emergent social motivations for tagging. The motivations that were found in the systems include expression, performance, and activism.

Problems related to synonymy, polysemy, different lexical forms, mispelling errors or alternate spellings, different levels of precision and different kinds of tag-to-resource association cause inconsistencies and reduce the efficiency of content search and the effectiveness of the tag space structuring and organization. They are mainly caused by the lack of semantic information inclusion in the tagging process. We propose a new way to describe resources: the semantic tagging. It allows user to state semantic assertions: each of them expresses a defined characteristic of a resource associating it with a concept. We present SemKey, a semantic collaborative tagging system, describing its global architecture and functioning along with the most relevant organizational issues faced.

Here we collect data from a popular system and investigate the statistical properties of tag co-occurrence. We introduce a stochastic model of user behavior embodying two main aspects of collaborative tagging: (i) a frequency-bias mechanism related to the idea that users are exposed to each other's tagging activity; (ii) a notion of memory - or aging of resources - in the form of a heavy-tailed access to the past state of the system. Remarkably, our simple modeling is able to account quantitatively for the observed experimental features, with a surprisingly high accuracy. This points in the direction of a universal behavior of users, who - despite the complexity of their own cognitive processes and the uncoordinated and selfish nature of their tagging activity - appear to follow simple activity patterns.

Existing techniques recom- mend tags on the basis of their popularity among the group of all users; on the basis of recent use; or on the basis of simple heuristics to extract keywords from the url being tagged. Our method is designed to complement these approaches, and is based on recommending tags from urls that are similar to the one in question, according to two distinct similarity metrics, whose principal utility covers complementary cases.

This poses two main problems. First, the appearance of both standard language and a community-related dialect, demanding that dialect words should be as much as possible corrected to standard words, and second, the automatic hierarchic clustering of texts by their topic. The problem of correcting dialect words is dealt with by performing a nearest neighbor search over a dynamic set of known words, using a set of transition rules from dialect to standard words, which are learned from a pair-wise lexicon. We tackle the clustering problem by implementing a hierarchical co-clustering algorithm that automatically generates a topic hierarchy of the collection and simultaneously groups documents and words into clusters.

The latter refers to concepts in which individuals tag locations with their own content, such as images, comments, audio, and video clips or game contents. This association is implemented in terms of a database, accessible for upload and download via the web. For an individual, an action of tagging is a kind of multimedia blog post, or an entry of a web guestbook. The focal issue is how locative content fuels meaning building in virtual communities.
