2 Agenda User searching on the Web  observation, difficulties and frustration A software proposition to help users  Individual assistance  Web services as basic component  The four Information access phases and involved components  Different H uman M achine I nterface for different users  Sequence diagram Phase 2 and 3 samples  Assessment Conclusion

10 The four Information Access Phases 1. Building query 2. Pickup in the heap 3. Just for me 4. As I want it, to save it and work on it

11 Phase 1: Building query The goal is: Creating a valid query Choosing determinant keywords Being in the right semantic space … Components could: Propose semantic spaces Translate acronyms to/from S mall M essage S ervice Propose synonyms of keywords Propose lists of icons to replace words Translate keywords in other languages, and so on.

12 Phase 2: Pick up in heap The goal is: Finding the relevant information in the proposed list Components could: Place information-bubbles to explain URL Place information-bubbles to give an abstract of the page Add a specific icon to explain contents, semantic space, sources of information and its’ nature Display results via a specific metaphor Translate text in a specific language, and so on.

13 Phase 3: Just for me The goal is: Getting information in the right format for a specific User Components could: Ajust display or adapt colors (for people affected by color-blindness) and/or adapt font size Colorize keywords Transform text into audio file or prepare to be printed in Braille Filter pornographic, violent images Adapt to specific hardware (phone, PDA…) Place information-bubbles giving a definition of “complex” word;

14 Phase 4: As I want it now The goal is: Transforming information in the right format to be manipulate, stored and shared Components could: Transform and save file in multiple formats (Word to PDF, PDF to XML, images to text using OCR, extract score from midi file …) Compare contents with other ones Fax, iPrint or mail the document Analyze document (count word, ontological classification, …) Summarize document content Search other documents having a similar content

18 Assessment Observations in coherence with the previous studies Key words Universality of the difficulties … Modeling the user Helping before qualifying Emergence of dynamic communities Modeling the components Components could be combined to help user in an infinity number of ways Open/shared space
