This document discusses folksonomy, which is a system of classification created by users tagging online items. It consists of users, tags, and resources. Users create tags to categorize and describe resources like web pages, photos, and videos. There are two types of folksonomy: broad, where multiple users can apply the same tag, and narrow, where each tag can only be used once. Social tagging allows users to collaboratively tag resources for knowledge acquisition. Folksonomies are used in many web applications and have advantages like being simple, flexible, and enabling discovery, but also have disadvantages like lack of control, precision, and consistency.
3. INTRODUCTION
◉ Folksonomy is a classification system in which end users apply public
tags to online items, typically to make those items easier for
themselves or others to find later. Over time, this can give rise to a
classification system based on those tags and how often they are
applied or searched for, in contrast to a taxonomic classification
designed by the owners of the content and specified when it is
published.
◉ Folksonomy was originally “the result of personal free tagging of
information for one’s own retrieval”,but online sharing and interaction
expanded it into collaborative forms.

4. ELEMENTS OF FOLKSONOMY
Folksonomies consist of three basic entities: users, tags, and resources.
Users create tags to mark resources such as: web pages, photos, videos,
and podcasts. These tags are used to manage, categorize and
summarize online content.
Folksonomy also includes a set of URLs that are used to
identify resources that have been referred to by users of different
websites. These systems also include category schemes that have the
ability to organize tags at different levels of granularity

5. Broad Folksonomy
A broad folksonomy arises when
multiple users can apply the same
tag to an item, providing information
about which tags are the most
popular. It allows for sorting based
on the popularity of each tag, as well
as the tracking of emerging trends in
tag usage and developing
vocabularies.
TYPES OF FOLKSONOMY
Narrow Folksonomy
A narrow folksonomy occurs when
users, typically fewer in number and
often including the item's creator,
tag an item with tags that can each
be applied only once.

6. SOCIAL TAGGING
◉ Social tagging for knowledge acquisition is the
specific use of tagging for finding and re-finding
specific content for an individual or group.
◉ Social tagging systems differ from traditional
taxonomies in that they are community-based
systems lacking the traditional hierarchy of
taxonomies.
Rather than a top-down approach, social
tagging relies on users to create the folksonomy
from the bottom up.

7. CONT..
Common uses of social tagging for knowledge acquisition include
personal development for individual use and collaborative projects.
Social tagging is used for knowledge acquisition in secondary, post-
secondary, and graduate education as well as personal and business
research. The benefits of finding/re-finding source information are
applicable to a wide spectrum of users. Tagged resources are located
through search queries rather than searching through a more
traditional file folder system. The social aspect of tagging also allows
users to take advantage of metadata from thousands of other users.

8. APPLICATION OF FOLKSONOMY
◉ Folksonomies are an essential part of many social software and web 2.0
based applications.
◉ Users can tag various types of data including scientific articles, references,
bookmarks, pictures, videos, audio files, blogs posts, discussions, events or
even other users.
◉ Folksonomies is also possible to work with other contexts like in intranets
of companies, for indexing corporate blogs, podcasts, for corporate
bookmarking services and message boards.
◉ Commercial online information suppliers have started to work with
folksonomies

10. CONCLUSION
Folksonomies present a valuable addition to the spectrum of knowledge representation
methods. With web users taking control over document indexing, folksonomies offer an
inexpensive way of processing large data sets. User centered approaches to tagging have
multiple benefits, as they can actively capture the authentic language of the user, are
flexible and allow new ways of social navigation within document collections.
Yet some problems derive from the unstructured nature of tags which may be solved by
improving the users’ tag literacy, by (automatic) query refinements, or by processing tags
through natural language processing. In the future, the advantages and shortcomings of
folksonomies will be considered more closely as advanced approaches to the use of social
tagging applications are emerging.
