AMTI Web 2.0 dan Social Networks

WEB 1.0 • Web 1.0 secara umum dikembangkan untuk pengaksesan informasi dan memiliki sifat yang sedikit interaktif • Sifat web 1.0 adalah read • One-way communication

Web 1.0 design elements • Static pages instead of dynamic user-generated content. • The use of framesets. • Proprietary HTML extensions such as the and <marquee> tags introduced during the first browser war. • Online guestbook rather than forum • Using GIF buttons • HTML forms sent via email • User never upload and posting content

WEB 2.0 • Menurut Tim O’Reilly, Web 2.0 dapat didefinisikan sebagai berikut: “Web 2.0 adalah revolusi bisnis di industri komputer yang disebabkan oleh penggunaan Internet sebagai platform, dan merupakan suatu percobaan untuk memahami berbagai aturan untuk mencapai keberhasilan pada platform baru tersebut. Salah satu aturan terutama adalah: Membangun aplikasi yang mengeksploitasi efek jaringan untuk mendapatkan lebih banyak lagi pengguna aplikasi tersebut” • Sifat dari web 2.0 adalah read write

Perbedaan 1.0 ke 2.0 • Move from personal websites to blogs and blog site aggregation, • Move from publishing to participation, • Move from web content as the outcome of large up-front investment to an ongoing and interactive process, • Move from content management systems to links based on tagging (folksonomy)

Folksonomy / Tagging • Folksonomi merupakan hasil pengategorian oleh pengguna. • Secara demokratis pengguna menerapkan tag sesuai dengan kecocokan mereka terhadap isi materi. • Folksonomi mengatasi kerumitan konsep kategori yang terstruktur formal dan bertingkat yang disebut taksonomi. • Kelemahan folksonomi misalnya tidak luput dari derau (noise), bisa terjadi ada banyak tag/label yang kosakatanya salah, tidak semua user tag/label tersebut cocok

Tagging

Social bookmarking •There are a number of sites for this •By far the most popular is http://del.icio.us •Rather than bookmarking sites locally allows you to have access to your bookmarks from wherever you are. •This is a small example of the “web as desktop” philosophy.

del.icio.us

Fitur Web 2.0 • Search – The ease of finding information through keyword search.

• Links – Ad-hoc guides to other relevant information.

• Authoring – The ability to create constantly updating content over a platform that is shifted from being the creation of a few to being constantly updated, interlinked work. In wikis, the content is iterative in the sense that users undo and redo each other's work. In blogs, content is cumulative in that posts and comments of individuals are accumulated over time.

• Tags – Categorization of content by creating tags: simple, one-word userdetermined descriptions to facilitate searching and avoid rigid, pre-made categories.

• Extensions – Powerful algorithms that leverage the Web as an application platform as well as a document server.

• Signals – The use of RSS technology to rapidly notify users of content changes.

Search • Search the content • Oracle Secure Enterprise Search Oracle Ultra Search • Google Search Appliance

Link • Build links to other content, users, etc. • Tracking/analyzing clicks/usage patterns is key

Authorships • Blogging and allowing users to create their own content • Wikis • Blogspot • Forums

Tagging • Labeling, categorization, grouping content • Google Mail – Automatic

Extensions • Web Services • Personalization components • External calls – Lookups – Mapping – Connecting – Calendaring

• Mashups

Signaling • • • •

Alerts Emails Notifications RSS

Google Calendar Example Google calendar is used: –For key library events –To allow event details to be embedded in a variety of sites, including pages on institutional Web site 35

The Competition

Better?

Better?

WEB 3.0 • Konsep ini dapat diandaikan sebuah website sebagai sebuah Artificial Intelegence – Konsep semantic web

• Aplikasi – aplikasi online dalam website dapat saling berinteraksi • Kemampuan interaksi ini dimulai dengan adanya web service
