Major ILS disciplines What does iSchools like SILS study? Information, Technology, People

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

Representation Structure, how do we represent Scholarly literatures Genomic Databases Students suggest…

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

Storage What physical form does information have? Where do we put it? How do we organize it? Ontology will analyze the most general and abstract concepts or distinctions that unlderly every more specific description of any phenomenon in the world e.g. time, space, matter, process, cause and effect, system

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

Information Storage/Exchange Data centric Databases Document centric markup languages (XML) Web based, large scale heterogeneous data sets Big Data analytics (noSQL)

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

Tools that help Finding Uses information representation structures (indexing, classification) Present via dynamic interface (show UNC library catalog example). Why is Google search effective Fast Comprehensive Direct connection to results

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

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

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

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

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