Unit 14 notes

the readying of this week talks about information retrieving services.

Paepcke, Andreas. (1996). Digital libraries: Searching is not enough. D-Lib Magazine, May. http://www.dlib.org/dlib/may96/stanford/05paepcke.html
It talks about digital library
"The main research problems derivable from this starting point are scaling and information finding: If only we can provide good performance for the standard information retrieval metrics of recall and precision when accessing very large collections, we will have a Digital Library.

3. Block, Marylaine (2002). "My Rules of Information." Searcher (10) 1: 61-67. (Available online at http://www.infotoday.com/searcher/jan02/block.htm)

this article talks about how Librarians know how to alocate information ."People assume that librarians must know all the answers, but what we really know is how to ask good questions. We know how to slide up and down that continuum from general to narrow until we find the exact set of parameters that work."

Notes: Unite13

I could not access the articles but I learn some information about it by readying article talks about Intelligent Information Retrieval. It is a very good article because it gives you an introduction about Intelligent Information Retrieval. Susan Gauch says “Technological advances have led to new problems and new solutions. The number, size, and contents of online databases has grown. Finding relevant information is truly a “needle in a haystack” proposition. In one study of inexperienced searchers, one-quarter of the subjects were unable to pass a benchmark test of minimum searching skill and This led people need the Intelligent information retrieval.

Unit 12: Retrieving information on the World Wide Web

1.Sullivan, Danny. (2003). Search Engine Watch. Review 2 short pieces: “How Do Search Engines Work?” at http://searchenginewatch.com/webmasters/article.php/2168031 and “How Search Engines Rank Web Pages” at http://searchenginewatch.com/webmasters/article.php/2167961>. (Date accessed: 8/19/2005)

- This website talks about how the search engine works.
- There are two types of search engine which are crawler-based search engines and human-powered directories

- crawler-based search engines: such as Google, create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found.
- Human-Powered Directories: A human-powered directory, such as the Open Directory, depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search looks for matches only in the descriptions submitted.


- Also it talks about how Search Engines Rank Web Pages: the search engine will sort through the millions of pages it knows about and present you with ones that match your topic. The matches will even be ranked, so that the most relevant ones come first.

Unit 11

Unit 11: Retrieving information in Digital Libraries:

1.Subject-based Information Retrieval within Digital Libraries Employing LCSHs

"In this article, an effort is made to exploit the explicit and implicit semantic expressiveness of subject headings conforming to the LCSH guidelines, in favor of more efficient subject-based, information retrieval modules within digital libraries."

Notes for unite # 8

Philip Greenspun. SQL for Web Nerds, chapter 3 “simple queries” and W3school. SQL tutorial

These two websites provide us with information about SQL and how we can start using it and how we can write queries. Moreover, they provide us with examples and tutorial which can teach us how to use SQL to access and manipulate data in.

Muddiest points for week # 7

Is assignment #2 depend on assignment # 1 ( is it continuation for
