- According to Morville and Rosenfeld, what are the basic schemes one can use to organize information? As you describe each scheme, also describe what kind of information the scheme is best suited for.
What is an organization scheme?
“Organization scheme defines the shared characteristics of content items and influences the logical grouping of those items.”
We navigate through organization schemes every day. Telephone books, supermarkets, and television programming guides all use organization schemes to facilitate access.
1. Exact Organization Schemes
The scheme is best suited for the users who know the specific name of the resource they are looking for. The schemes won’t work very well if user is looking for a general type, for example electrician, plumber, etc. It will show you what you have saved with specific name and words.
1. Alphabetical
As the name suggests an alphabetical organization scheme uses alphabetical order to find something. This scheme is the primary organization scheme for encyclopedias and dictionaries.
2. Chronological
Sometimes information has to be saved with reference to date and the event that had happened on a specific date. Usually History books, magazine archives, diaries, and television guides tend to be organized chronologically.
3. Geographical
Schemes that uses location to organize data like weather, shops located, and the most latest news around the world is organized Geographically. With the exception of border disputes, geographical organization schemes are fairly straightforward to design and use.
2. Ambiguous Organization Schemes
Again, as the name suggests Ambiguous or “subjective” organization schemes divide information into categories that defy exact definition. Although they are difficult to design, they are mired in the ambiguity of language and organization, not to mention human subjectivity. Here the user can search the whole group without being specific.
1. Topic
This scheme is the most common and useful scheme as it organizes information by subject or topic which makes it challenging approaches to develop. Academic courses and departments, newspapers, and the chapters of most nonfiction books are all organized along topical lines.
2. Task
Task-oriented schemes organize content and applications into a collection of processes, functions, or tasks. These schemes are appropriate when it’s possible to anticipate a limited number of high-priority tasks that users will want to perform.
3. Audience
In cases where there are two or more clearly definable audiences for a web site or intranet, an audience-specific organization scheme may make sense. This type of scheme works best when the site is frequented by repeat visitors who can bookmark their particular section of the site. It also works well if there is value in customizing the content for each audience.
4. Metaphor
It means creating similar options for similar tasks. Metaphors are commonly used to help users understand the new by relating it to the familiar. for example using trash can as the icon to delete files on computer.
5. Hybrids
The perfect combinations of all the schemes bring us to Hybrid scheme. The power of a pure organization scheme derives from its ability to suggest a simple mental model that users can quickly understand. One of the best example can be google search bar.
- Why did Netflix develop their microgenre feature, and how did they categorize their movies? Why didn't they just let end-users tag movies like Flickr or YouTube allow?
Netflix possesses 76,897 unique ways to describe types of movies.
Netflix makes it wonderful program work by using large teams of people specially trained to watch movies. They are paid people to watch films and tag them with all kinds of metadata. This process is so sophisticated and precise that taggers receive a 36-page training document that teaches them how to rate movies on their sexually suggestive content, goriness, romance levels, and even narrative elements like plot conclusiveness.
They capture dozens of different movie attributes. They even rate the moral status of characters. When these tags are combined with millions of users viewing habits, they become Netflix's competitive advantage. These tags are then run down in a algorithm which helps Netflix to distribute movies in specific categories. The company's main goal as a business is to gain and retain subscribers. And the genres that it displays to people are a key part of that strategy as it makes the interface user friendly and allows user to quickly select the best movie they could watch at that point of time, which definitely increases the numbers of views and users.
And now, they have a terrific advantage in their efforts to produce their own content: Netflix has created a database of American cinematic predilections.
“Yellin said that the genres were limited by three main factors: 1) they only want to display 50 characters for various UI reasons, which eliminates most long genres; 2) there had to be a "critical mass" of content that fit the description of the genre, at least in Netflix's extended DVD catalog; and 3) they only wanted genres that made syntactic sense.” This kind of categorization is actually very good and is based on hybrid organizational scheme.
They didn’t just let end-users tag movies like Flickr or YouTube allow because
Netflix had decided to "go beyond the 5 stars," which is where the personalized genres come in and made this a whole new experience.
