11. What is a Document? A Terminology Issue Information object Information object –Document –Information resource –Information bearing entity –Bibliographic entity Exist in the world of recorded knowledge…

12. Information Objects, W3C W3C/IETF definition of resource is “…anything that has identity. Familiar examples include an electronic document, an image, a service (e.g., "today's weather report for Los Angeles"), and a collection of other resources. Not all resources are network "retrievable"; e.g., human beings, corporations, and bound books in a library can also be considered resources.” i.e. a resource is “anything” –physical things (books, cars, people) –digital things (Web pages, digital images) –conceptual things (colours, points in time, subjects)

13. Information Objects “Any entity, form or mode for which contextual data can be recorded” (Greenberg, 2002, 2003)

14. Information Objects Is our conception too wide, vague, ambiguous? –DCMI (Dublin Core Metadata Initiative) Type Vocabulary: Collection, Dataset, Event, Image (Still or Moving), Interactive Resource, Service, Software, Sound, Text, Physical Object

16. Our context …(inls 150, and our field) Information systems contain documents (objects)

17. What kinds things might we represent in information systems? Concrete things: books, documents, movie clip, map Persons: role, doctor, student, taxpayer Events: accident, birth date, divorce Transactions: sale of item (purchase) Other?

20. Representation Description, stand-in, surrogate --------------------------------------- Knowledge Representation: http://groups.csail.mit.edu/medg/ftp/psz/k-rep.html http://groups.csail.mit.edu/medg/ftp/psz/k-rep.html AI: http://www.aaai.org/AITopics/html/repr.html http://www.aaai.org/AITopics/html/repr.html HTML: http://www.w3.org/TR/html4/charset.htmlhttp://www.w3.org/TR/html4/charset.html

21. Representing objects in Information Systems You can recognize it as a discrete object (entity) –Even if it is a complex or compound object You can name it by applying labels (attributes and values to attributes) You can manipulate it You can describe it

22. Representation Devices and means –Icons, images, graphs, symbols, numbers, words, strings, descriptions Content (conceptual meaning) –Aboutness »Subject content Carrier (packaging) –Physical representation –Models, measurements, strings, bytes, etc.

23. Representation Terminology Element = Attribute + Value. Attribute (property of the object). –Who-what-where-when-why. Photographer (person/agency), title, place of, date. Value (content associated to the attribute). NASA Photographic Services, Shuttle Columbia, Kennedy Space Center in Florida, January, 2003.

24. What Makes a Good Representation? Captures essential elements Never the same as the thing being represented (abstraction) [surrogates] Get the abstraction right (accurate representation) Appropriate for the person / audience Appropriate for the task / function

32. Goals Process and Goals for Organizing Information in an information system Information is out there or being/will be created… Identify 3-5 steps in the information organization process. List 3-5 goals or objectives of your information systems once it’s organized.

33. Process Identify –Identify what you are going to organize –Different scenarios. Collect –Get it. Different means. Provide Access –Representation/description, indexing, etc.

34. Goals: Allow the user to Find information when it is known. Discover new information. Evaluate information as to its use. Retrieve/Locate the information
