Major Functions
Definition of a Function: Important Functions:
Feature 1: Messaging
Description
Messaging serves an important function in LinkedIn because it allows you to communicate with employers, groups, and the connections that you make while using LinkedIn.Messaging is used by people to communicate. In LinkedIn you can message a group by either blogging or actually writing them an email. You can also leave comments behind critiquing their blog posts. Blogging in a group allows the comment to become readable to the public where as messaging a connection allows only that person to see what you have wrote.
User Interface
The User Interface for messaging in Linked in involves a series of tabs and a hyper linked text. It is similar to many other User Interfaces that many email providers have. When you click on Sent it opens up the outbox that displays the messages that you sent out. Same for trash which shows the files that you deem unworthy for future viewing and it even has an archive feature that you can use to store email.
Algorithm
Information is stored so that users can track their communication with their connections. In LinkedIn once a message is sent to the connection it alerts them and when you receive a message it alerts you as well.
Info Types and Organizational Structures
Linked in uses a standard email display that overlaps the regular display of a Linked in profile account. It has a page area for the body of your email, a To: From: and Subject: area and hyper linked text on the right with the words Sent, Inbox,Trash and Archive. Also included are tabs labeled Messages and Invitations. The messages tab sends you to your inbox and such while the Invitation Tab sends you to a page where you can upload your contacts from another email and sent them an invitation to become a connection on LinkedIn. The info types that are used in LinkedIn messaging include Messages and User.

Linkedin users build new relationship quickly by joining and sharing interest groups. “Group directory” section allows users search specific or related to career group.

As the users join in certain communities, the people in the communities can see Linkedin users on their pages. Being discoverable will let search engines find Linkedin users, which allows the users to have better opportunities to find their jobs and groups. The interface is very typical: as the users create a complete profile, which includes a lot of information boxes, the users automatically become searchable. Linkedin will store, and organize your profile; after that, the users will be likely to be shown on the top of the list when people use Google search and type the users’ names
Feature 4: Search for info type

The user can then enter the key word(s) they wish to query into the input field (location 3 in red) and then submit their entry to be delivered the search results page. The results of the query are listed in a sequence in the middle (location 1 in red) of the screen based on the refinements the user makes to the search algorithm. Refinements may be made on the left side of the screen (location 2 in red) by expanding each subject and checking or unchecking the given options.
Algorithm
Linkedin’s search algorithm allows users to search through all profiles or other info-items on the within their network. The relevancy of the results is ordered by keyword similarity and network connections to the user. Different methods of sorting the results are also provided such as by relationship, reference and keyword only. Refinements to the search algorithm can also be done by specifying keywords and info-types before making a query, allowing the user to narrow their search results. The Linkedin search algorithm also allows for the use of modifiers in the search field such as quotes, NOT, OR, AND, and parenthesis.
Info Types and Organizational Structures
The drop down menu in the navigation bar allows for search through the info-types such as, people, updates, jobs, companies, answers, messages and groups. The Search results are given to the user in a sequence structure based on relevance. The refinement options are in a hierarchical structure, expanding to more options for the user when clicked on.
