Social Web
• The Social Web is currently used to describe how people socialize or interact with each other through the World Wide Web. Such people brought together through a variety of shared interests.
- wikipedia, social webhttp://en.wikipedia.org/wiki/Social_web
Social Web
•The Social Web consists of people who are connected by a shared object.
- Social Graph : the network of connections and relationships between people.
- Social Object : the reason, people are talking to each other.

Streams
•The cleanest and simplest way to navigate a Social Web
•Streams are rapidly changing sequences of information around the topic
- microblogs, feeds, even data streams.
•Streams are real-time, flowing, dynamic activity of information

Social Web Issues
Current Social Web
•While current social web gained a lot of interest of the Web. It also raises various Issues.
- multitude of online identities and social graphs
- Isolated data silos.
- Unstructured contents.
- Scattered conversations.
We need a way...
•for representing and navigating the content items in these sites. Also to better enable user to access to multiple sites and to content-creation facilities on the Web, interoperability among social web is required in term of both the content objects and the person-to-person networks expressed on each site.
•This requires representation mechanisms to interconnect people and objects on the Web in an interoperable and extensible way.
Semantic Streams
Semantic Streams
•It allows users to merge user's multitude of online identities, social graphs and interconnect from isolated data silos to structured contents
•It enables generation of streamed RDF data from existing Social Web(streams) sites.
Identity and Social Graph
Identity
•Social Web users can have multitude online accounts, passwords and profiles
- maintaining a multitude of profiles is cumbersom and consuming
- each platform contains a different facet of their online identity
Distributed Identities

Distributed Social Graphs
FOAF(Friend of a Friend)
- The FOAF is creating a Web of machine-readable pages describing people, the links between them and the things they create and do
- It allow for a more expressive description of a social network, enabling the use of heterogeneous nodes and links denoting different types of objects and different types of relationships.

Describing Relationships

- used to create a friend link
•foaf:knows, (extended with the Relationships vocabulary
- :me foaf:knows :you
- :me rel:friendOf :you

Streams
•Most Social Web services act as closed worlds like.
•At present, the content of Streams does not carry any semantics, making its use difficult
SIOC(Semantically-Interlinked Online Communities)
•SIOC aims to enable the integraion of online community information
•SIOC fully describe the contents and structure of community sites

Filtering
Filtering
•We can follow many streams.
•Cramming all our separate stream into merge activity stream get too noisy and overwhelming to use.

Filtering
•We need away that can adapt to filter the Stream differently based on what we now care about.
Social Filtering
•We need ways that can adapt to filter the Stream differently based on what we now care about.
- to see just the things that are really fun, important, popular or likely to be of interest and value to users, instead of everything
Social Filtering
Approach
•Social Filitering
- filters information based on User Affinity, which is measured by degree of user relationship, and frequency of communications or interactions between users
- filters information based on User Topics(or user context)
User Affinity•Measuring degree of user relationship
- based on user affinity among multiple Social Graphs
- Explicit
‣ based on merged social graphs
- Implicit
‣ based on user interactions : frequency of communications and methods of communication
Merged Social Graphs
degree of user relationship

Measuring of user Interactions
User Topics
•What is user talking about?
- Keywords, tag, link, metadata...
•Social Context
- SC = f(P,E) P:Person/Personality E:Environment
Social Filtering
•Who
- user(actor)
•With Whom
- based on user social graphs
•What
- topics
- user context

Components of Semantic Streams
Layers of Semantic Streams
•Unified User Identity and Social Graph
•Stream Parsing Engine
•Smart Data
•Republishing Activity Streams
•Conversations
•Social Filtering
Streams Parsing Engine
•Import Streams
- the process importing streams and parsing it
- the process analyzing streams
•Discovery
- the process in which machines find out information about the Web resources
- metadata crawling
Smart Data
•Smart data is a key factor for Social Filtering
- User implicit/explicit data
- conversations data
- streams & metadata
- context data
