  3. Keyword is : GAS How important is CONTEXT?

  4. Why is CONTEXT important? • As information architect Peter Morville stated in his User Experience Design article years ago,”…we must strike a unique balance on each project between business goals and CONTEXT, user needs and behavior, and the available mix of content.”

  5. The KWIC System • Key Word In Context: The index is formed by sorting and aligning words within a sentence. This allows each word to be searchable alphabetically in the index. • Input: An ordered set of lines • Method: Any line is circularly shifted (repeatedly remove the first word and append it to the end) • Output: All circular shifts of the line in alphabetically ascending order

  6. Functional Requirements • Accept an ordered set of lines. • Output all circular shifts in a sorted manner. • Allow users to select the mode of search (AND/OR/NOT).

  7. FR 1: Accept an ordered set of lines Define Delimiter Use Return Key

  8. FR 2: Output all circular shifts in a sorted manner Random Order Alphabetical Order Based on Frequency

  9. FR 3: Allow user to select mode of search (AND/OR/NOT) Radio Buttons Individual Textboxes Enter Keywords (+/-/!)

  10. Non Functional Requirements Understandability Enhance-able Portability

  11. NF 1: Understandability Understandability Any user can easily navigate and use the system. Resolution: Buttons and other UI items are properly labeled. In addition, proper instructions are included on the web page.

  12. NF 2: Enhance-able Enhance-able: Enhance-able can lead to mean the system is modularized and independent Resolution: The system is developed using OO concepts. Addition of new features doesn’t affect other modules.

  13. NF 3: Portability Portability: This feature enables the codebase to be reused instead of rewriting the code when moved to a new environment Resolution: Used Object Oriented Style which allows modifiability and adaptability without affecting the other modules

  14. Architecture Specification • Available Options: • Shared Data Architecture • Implicit Invocation Architecture • Pipe & Filter Architecture • Abstract Data Type Architecture • Our choice: Abstract Data Type (ADT) Architecture

  15. Shared Data Architecture • Data is communicated between the components through shared storage Advantages- • Performance, space and time • Efficient data representation as same storage is shared • No copying of data Disadvantages- • Modifiability • Enhanceability • Reusability

  16. Implicit Invocation • Component integration based on shared data • Interface to the data is more abstract than in shared data (like in ADT) • Computations are invoked implicitly as data is modified based on active data model Drawback- Difficult to control the order of processing

  17. Pipe and Filter • Each filter processes the input data and output data • Each filter can run whenever it has data on which to compute • Data sharing between filters is strictly limited to that transmitted on pipes Drawback- Difficult to support on interactive system

  18. Why ADT? • Complex systems can be built as a collection of small autonomous interacting agents • More flexible for changes

  19. Why ADT? • Changes to the data can be easily accommodated (the object using that data maintains the same input and output formats) • Supports the reusability of existing classes and objects

  20. Disadvantages of ADT • Objects should know the identity of other objects • It is difficult to control the exact ordering of modules called internally by these objects • When the identity of the object changes it is necessary to modify all objects that invokes it • Advantages > Disadvantages = Optimal Solution

  21. Why did we still choose ADT? • The style is suited for cases where the data representation is likely to change during the lifetime of the system • Class concept allows us to relate similar objects and reuse code through the inheritance mechanism

  23. Traceability Matrix

  24. Traceability Matrix

  25. Our Future Enchantments (- Why we are better) Depending on context of time and resources we may choose to implement the following: • Sorting based on user relevance (Example IMDB), • Method 1: Specifying the rules in the program (hard-coded),          • Method 2: Specifying the rules in a Dashboard. • Update our website to a better design

  26. Dashboard Feature

  27. Example: IMDB
