  1. LIS618 lecture 0 Thomas Krichel 2003-01-22

  2. Organization • homepage http://wotan.liu.edu/home/krichel/lis618p03s • Contents to be discussed today. • Send mail to krichel@openlib.org • Your name • Your secret word for grades delivery • Interrupt me with as many questions as possible! • Ask for breaks!

  3. Proposed Organization • Normal lecture • Quiz at the beginning of every lecture • Remove two worst performances • Average to form 50% • No quiz next week! • Search exercise 50% • Formal syllabus to be made early next week!

  4. Enlargement of hours • I would like to make the sessions longer • To compensate, some weeks would not have class • Such weeks would be concentrated at the end of the term • Advantages for students • Saves students time to travel • Improves grades because of worst performance discount. • I will not be there some weeks, may have to add extra out-of-class work.

  5. Search exercise • find victim of an information need • conduct interview about an information need experienced by the victim, write down expectations • search in Dialog and on web • discuss results with the victim • write essay, no longer than 7 pages.

  6. About me • Born 1965, in Völklingen (Germany) • Studied economics and social sciences at the Universities of Toulouse, Paris, Exeter and Leiceister. • PhD in theoretical macroeconomics • Lecturer in Economics at the University of Surrey 1993 and 2001 • Since 2001 assistant professor at the Palmer School

  7. Why? • During research assistantship period, (1990 to 1993) I was constantly frustrated with difficult access to scientific literature. • At the same time, I discovered easy access to freely downloadable software over the Internet. • I decided to work towards downloadable scientific documents. This lead to my library career (eventually).

  8. Steps taken I • 1993 founded the NetEc project at http://netec.mcc.ac.uk, later available at http://netec.ier.hit-u.ac.jp as well as at http://netec.wustl.edu. • These are networking projects targeted to the economics community. The bulk is • Information about working papers • Downloadable working papers • Journal articles were added later

  9. Steps taken II • Set up RePEc, a digital library for economics research. Catalogs • Research documents • Collections of research documents • Researchers themselves • Organizations that are important to the research process • Decentralized collection, model for the open archives initiative

  10. Steps taken III • Co-founder of Open Archives Initiative • Work on the Academic Metadata Format • Co-founded rclis, a RePEc clone for (Research in Computing, Library and Information Science)

  11. Interest in databases • From my point of view I have two interests in database searching • As a provider, I must understand how people search in order to provide some data that they can use and will use. • As an economist, I have a strong interest in information as a commodity. The database market is an important market place.

  12. Database searching (DS) • subset of the subject of information retrieval (IR) • DS mainly thought as applicable to the set of large structured databases as opposed to do web searching • for those, a general knowledge of what databases are seems useful • Concentrate on textual databases

  13. traditional social model • user goes to a library • describes problem to the librarian • librarian does the search • without the user present • with the user present • hands over the result to the user • user fetches full-text or asks a librarian to fetch the full text.

  14. economic rational for traditional model • In olden days the cost of telecommunication was high. • database use costs • cost of communication • cost of access time to the database • the traditional model controls an upper bound on costs

  15. disintermediation • with access cost time gone, the traditional model is under threat • there is disintermediation where the librarian looses her role • but that may not be good news for information retrieval results • user knows subject matter best • librarian knows searching best

  16. Web searching • IR has received a lot of impetus through the web, which poses unprecedented search challenges. • with more and more data appearing on the web DS may be a subject in decline • it is primarily concerned with non-web databases • There is more and more web-based methods of searching
