Overview

The social-semantic web (s2w) aims to complement the formal Semantic Web vision by adding a pragmatic approach relying on description languages

A specification language is a formal language used in computer science.Unlike most programming languages, which are directly executable formal languages used to implement a system, specification languages are used during systems analysis, requirements analysis and systems design.Specification...

Ontology (computer science)
In computer science and information science, an ontology formally represents knowledge as a set of concepts within a domain, and the relationships between those concepts. It can be used to reason about the entities within that domain and may be used to describe the domain.In theory, an ontology is...

. A socio-semantic system has a continuous process of eliciting crucial knowledge of a domain through semi-formal ontologies, taxonomies or folksonomies. S2w emphasize the importance of humanly created loose semantics as means to fulfil the vision of the semantic web. Instead of relying entirely on automated semantics with formal ontology processing and inferencing, humans are collaboratively building semantics aided by socio-semantic information systems. While the semantic web enables integration of business processing with precise automatic logic inference computing across domains, the socio-semantic web opens up for a more social interface to the semantics of businesses, allowing interoperability between business objects, actions and their users.

Socio-semantic web was coined by Manuel Zacklad and Jean-Pierre Cahier in 2003 and used in the field of Computer Supported Cooperative Work

's book Ambient Findability. In Chapter 6 he defines the socio-semantic web as relying on "the pace-layering of ontologies, taxonomies, and folksonomies to learn and adapt as well as teach and remember." We are seeing an increasing use of folksonomies on the web, and a corresponding decrease in the use of hierarchical taxonomies. Morville, the recognized librarian and information architect writes; “I’ll take the ancient tree of knowledge over the transient leaves of popularity any day”. There is undoubtedly scepticism towards the widespread and bushfire like adoption of folksonomies. The socio-semantic web may be seen as a middle way between the top-down monolithic taxonomy approach like the Yahoo! Directory

The Yahoo! Directory is a web directory that rivals the Open Directory Project in size. The directory was Yahoo!'s first offering. When Yahoo! changed to crawler-based listings for its main results in October 2002, the human-edited directory's significance dropped, but it was still being updated in...

 and the more recent collaborative tagging (folksonomy) approaches.

The socio-semantic web differs from the semantic web in that the semantic web often is regarded as a system that will solve the epistemic interoperability issues we have to day. While the semantic web will provide ways for businesses to interoperate across domains the socio-semantic web will enable users to share knowledge.

Morville is vague in his definition of the socio-semantic web and does not lay out any proposed models. We have identified three possible social approaches for solving the problems of user driven ontology evolution for the semantic web. First, users could create a folksonomy (flat taxonomy). With Social Network Analysis (SNA) in conjunction with automated parsers, the ontology could be extracted from the tags and this ontology could be entered into a Topic Map
Topic map
Topic Maps is a standard for the representation and interchange of knowledge, with an emphasis on the findability of information. Topic maps were originally developed in the late 1990's as a way to represent back-of-the-book index structures so that multiple indexes from different sources could be...

 ontology store. Secondly a set of ontology engineers or ontologists could manually analyze the tags created by the users and by using this data, create a more sound ontology. The third approach is to create a system for self governance where the users themselves create the ontology over time in an organic fashion. All of these approaches could start out with an empty ontology or be seeded manually or with an existing ontology, for example the WordNet
