1 Information Science Overview n Representation of Information (Knowledge) n Storage of Information n Finding/Re-Finding Information n Exchange/Sharing of Information n Using Information

2 Representation n Structure, how do we represent –Scholarly literatures –Databases –Students suggest…

3 Storage n What physical form does information have? n Where do we put it? n How do we organize it?

Storage over time… n Or how technology changes everything –Oral exchange (memorizing the Iliad). –Printing press: books –Computers: electronic materials –Web, world wide sharing, publishing 4

Finding & Re-finding n Searching out information –How did a researcher search for information 500 years ago? –50 years ago? –Today? 5

Tools that help Finding n Indexing n Classification n We will discuss both in more depth later 6

Exchange/Sharing n How is information shared or exchanged n (500 years ago/ 50 years/ today) n What are some technologies used today for sharing/exchange? 7

Advantages of Sharing n How does sharing/exchange help with finding? n Student suggestions? (hint, what are some of the things that shopping sites like Amazon do, or social networks like delicious?) 8

Using Information n observers read, view, listen to information to help them make decisions, come to conclusions. n What are the ways we interact with information? (paper, electronic) n For electronic the interaction can be dynamic (HCI/CHI, Human Computer Interaction). n Visualization, dynamic interfaces 9

How is technology changing everything? n Storage, transmission, display, use are all primarily electronic. n No longer one single copy but infinitely available, 24/7/365. Everyone has access. Human Genome project. 10

Changes, cont’d n Interactive instead of Static Displays n Collaborative Work n Dynamic interfaces n Machine processing (indexing, classification, decision making) 11

Major ILS disciplines n What does SILS at UNC study? n Information, Technology, People 12

n Information Structure –Classification –Indexing –Metadata –Structured representations of knowledge (controlled vocabularies, thesauri, taxonomies, ontologies) 13

n Information Storage/Exchange –Databases –Markup languages (XML) –Web 14

n Information Interactions –Seeking/Search –Sharing –Interaction –Visualization 15
