Joint indexing (English collaborative day-went or social day-went) is a form of the indexation (usually as if day-went designation), with the descriptors (tags) by a larger group and with the help of different kinds by social software to be assigned. The Indexierer meets thereby spontaneously in open communities, without detailed indexation rules would have been specified before. With the indexed objects it concerns for example bookmark (social bookmarks), or photo. The collections of tags, provided by joint indexing, are called also Folksonomies (luggage word from English folk and taxonomy).

Joint indexing is used particularly for indexing. Since the techniques are still rather new, an established theory of joint indexing does not exist yet. One assumes on meaningful and conclusive allocations agree a large number of users, so that thus after some time one of the users provision width unit key word system results, which contains a core existence of terms, useful for search purposes.

Example: Provide if I mean photos from Chicago in Flickr with the day Chicago, I make it for other users possible, who are interested in photos, which stand with Chicago in connection, to find over the day search also my photos. This proceeding can be problematic when synonyms or abbreviations, therefore frequently more than one day is used.

A popular example is Social Bookmarking, with which are made accessible Related links over tags.

One day can consist - dependent on the offerer - of one or more words.

Emergence and origin

The emergence of the luggage word Folksonomy out "“folk"” (people) and "“taxonomy"” (taxonomy), thus about "“classification by the people"” is attributed to Thomas Vander whale. The system was applied first to the web page del.icio.us in the year 2003.

2004 implemented Jon Udell that this kind of categorization already admits was, again are however the possibility feedback by the individual user.

Folksonomy and formal classification

Contrary to formal classifications by professional experts like librarians there is e.g. no instance, which specifies and controls the key words which can be used with the Folksonomy. With the Folksonomy exists no hierarchy of categories: One can arrange thus no category in another.

Application

The Folksonomy applies its mainly on Internet sides and/or in those from them to offered communities. These offer the possibility a certain kind of information to their users like for example social bookmarks, photos or the entries of their Blogs to key words. Other users find these information then by the search for a key word.

Gladly one serves with that the most popular key words of the diagram of a word cloud (day cloud) typographically most largely to present itself.

Pro and cons

The proponents of the Folksonomy promise themselves from the fact that the information is categorized by those, which also use it better results. Information and connections, which were not noticeable to the particular, are to be made by the mostly large number of users visible.

However it comes by the free selection of the key words to a splintering of the categories: it becomes for instance the same thing of some users in the Singular (example: Book) and of others in the Plural (books) marks. In addition a Folksonomy comes into different languages at international communities (book, books, Books, Book etc.). With compound terms one can itself, if only one word and not several are technically certified, for a separator (open_access) or writing together decide (open ACCESS).

With the help of the announcement of to each other similar key words one tries to work against this splintering. As the further corrective the mass at users is regarded, whom user could bring to orient itself at the most popular in each case key word.

A further disadvantage is the homonymy problem with the free Verschlagwortung: The exact meaning tags often hangs of the context off and can also for completely different concepts. Thus for example the English word stands "„apple "“generally linguistic usage for the fruit apple, while in the computer industry the company Apple computer can be meant and in the music industry the disk label Apple record.
