Definition

  • Social software (also called social networking software) enables social computing, i.e. it enables people to rendezvous, connect or collaborate through computer-mediated communication and to form online communities.

See social computing for conceptual issues.

Types of social software

In a way, any sort of CMC can be called social software since communication is inherently social, e.g. any sort of groupware (e.g. simple forums, project management software), educational web-services like LMSs, virtual environments, MMORPG-like games, ....

However, we prefer a more narrow definition of social software that includes applications that add an "extra touch" in the spirit of what some interpret as "web 2.0".

Below is first attempt to list various kinds of software. I certainly will have to go over this and separate types of Internet applications from various components that can constitute such applications.

Sharing of links and feeds

Often such systems feature folksonomy tagging and sometimes tag clouds, i.e. a visual depiction of content tags used on a website.

  • Hybrid systems like NewsVine that allow to read, discuss and vote for news stories. Also allows to write article like in News engines à la slashdot.
  • User powered content like Digg. Everything is submitted and voted on by the digg community.

Sharing of digital artifacts

Such applications are not just indexed uploads/downloads (e.g. like in more traditional portals). There are also tagging mechanisms.

Examples
  • File sharing like Furl
  • Any sort of writing tool that can be shared and has a social flavor

Social citations and reference managers

This is huge and fast growing area of use to researchers.

Social shopping

Such systems include reviews, recommendation systems (including social navigation elements) and can include reputation systems

Examples are:

  • Amazon, various add-ons like reviews, X who bought A also bought, Person X has a good rating, ...
  • Kadboodle
  • Epinions (reviews and ratings)

Social network construction and maintenance

Relation web services and sofware like

  • FOAF
  • frienster,
  • Tribe
  • LinkedIn
  • Orkut
  • Elgg.net - education community
  • Elgg.org - open-source software used by elgg.net: this social network software supports a number of open standards including RSS, LDAP, FOAF, and XML-RPC
  • LiveJournal - online-blog-plattform with community-building fonctionnalities

These website usually specialize on some kind of relations (professional, interests, dating, ..). There exist also associated social network search engines.

Groupware

Most groupware is rather limited to coordinate work within a well defined community. But there are some applications that are more open potentially.

  • E.g. Google calendar that allows to merge personal and public calendars.

Reputations systems

According to Wikipedia, a reputation system is a type of collaborative filtering algorithm which attempts to determine ratings for a collection of entities, given a collection of opinions that those entities hold about each other. This is similar to a recommendation system, but with the purpose of entities recommending each other, rather than some external set of entities (such as books, movies, or music).

Reputation systems can used in conjunction with other systems.

Collaborative filtering

According to Wikipedia, Collaborative filtering (CF) is the method of making automatic predictions (filtering) about the interests of a user by collecting taste information from many users (collaborating). The underlying assumption of CF approach is that: Those who agreed in the past tend to agree again in the future. For example, a collaborative filtering or recommendation system for music tastes could make predictions about which music a user should like given a partial list of that user's tastes (likes or dislikes). Note that these predictions are specific to the user, but use information gleaned from many users.

Blogspheres

  • blogs (under the condition that they make use of networking features like RSS feeds, backtracking, etc.

Large Wikis

  • Projects like [Wikipedia] that involve a few hundreds of people, that have features to categorize information etc. could be considered (to be discussed).

Note: (DSchneider doesn't consider this wiki to be social software since there are not enough participants. It's more like a cognitive tool for the authors of articles and for our users it's more like a tool for finding definitions and links. Sometimes, it may evolve into a simple form of cognitive flexibility hypertext).

Social software in education

DSchneider believes that this will be one of the big trends in coming years. Some applications are already being used, in particular in higher education. See social computing for more in depth discussion.

  • To share pointers (links, references, etc.): social bookmarking, citation indexes, reference managers
  • To exchange ideas and to work collaboratively on texts: blogs and wikis and other shared writing tools.
  • To network: social network tools (see above)
  • To share and organized digital artifacts: Picture and file sharing tools.

As an alternative to "heavy and not flexible" Learning management systems, new providers may offer "light weight" services that individual teachers could used for the classroom or blended teaching. I.e. see Google for educators as a first attempt (17:13, 19 October 2006 (MEST)).

Links

Web Sites, blogs, etc.
