Week 13 Notes

Total "Terrorism" Information Awareness (TIA):
-very interesting, scary, and informative site
-2002, Total Informtaion Awarness: intended to detect terrorists through analyzing troves of information.
- TIA purported to capture the "information signature" of people so that the government could track potential terrorists and criminals
- called for the development of "revolutionary technology for ultra-large all-source information repositories,"
- develop data-mining or knowledge discovery tools that would sort through the massive amounts of information to find patterns and associations.
- development of biometric technology to enable the identification and tracking of individuals
- September 2003, Congress eliminated funding for the controversial project and closed the Pentagon's Information Awareness Office
-site includes news items, documents, and resources

No Place to Hide site:
-“ When you go to work, stop at the store, fly in a plane, or surf the web, you are being watched. They know where you live, the value of your home, the names of your friends and family, in some cases even what you read. Where the data revolution meets the needs of national security, there is no place to hide.”
- No Place To Hide: multimedia investigation by news organizations working together across print and broadcast platforms, to make a greater impact than any one organization could alone
-Interactive site with interviews, reviews, extended learning projects, links
-seems very validated by the sources which have reviewed them

Youtube Video:
-“this video is no longer available due to a copyright claim by Viacom International Inc.”

Week 10 Muddiest Point

It seems to me that the regular Google search engine, and especially google scholar have more direct resluts than google image, is there a difference in how they sort and retrieve or is it mainly due to how people label images

Week 10 notes

David Hawking , Web Search Engines

Part 1:
-modern search engines do more than was ever believed possible
-article focus= go behind the scenes and explain how this data processing "miracle" is possible
- search engines must reject as much low-value automated content as possible, its cost effective
- Currently, the amount of Web data that search engines crawl and index is on the order of 400 terabytes
- simple crawling algorithm must be extended to address the issues of speed, politeness, excluded/duplicate/continuous content, and spam rejection
- Engineering a Web-scale crawler is not for the unskilled or fainthearted (tag, im out)

Part 2:
-focus= “reviews the algorithms and data structures required to index 400 terabytes of Web page text and deliver high-quality results in response to hundreds of millions of queries each day.”
- Search engines use an inverted file to rapidly identify indexing terms
-goes over concepts of scaling up, term lookup, compression, phrases, anchor text(kinda interesting), link popularity scores, and query-independent scores
- major problem with the simple-query processor is that it returns poor results
-technology to speed things up= skipping, early termination, assignment of document numbers, caching(something I knew of before this article, yay)
-now interested in suggestions of generating advertisements targeted to the search query and generating spelling suggestions from query logs


Current developments and future trends for the OAI protocol for metadata harvesting:

-article looks at developing trend of Open Archives Initiative protocol for metadata harvesting, initiated originally for e-print archives community, mention of Mellon Foundation, the article and development is interesting. Though I am more into paper based documents, it seems more likely every day that I will have to know and work with these types of documents and databases, as the archival community continues to shift and develop

The Deep Web: Surfacing Hidden Value:

-This article was very enjoyable, I found it easy to read, enjoyed the metaphors, graphs and charts (yay pictures). The internet is way to vast for the common person to conceptualize and this article aided in my understanding of a complex tool/resource I typically take for granted

Week 9 muddiest point

Week 9 notes

Martin Bryan. Introducing the Extensible Markup Language

-XML= not a large clothing size, but subset of the Standard Generalized Markup Language designed to make it easy to interchange structured documents over the Internet
-always clearly making beginnings and ends, ensures fall back options are available when access to certain components of the document is not currently possible over the Internet
-allows users to: bring multiple files together to form compound documents; identify where illustrations are to be incorporated into text files, and the format used to encode each illustration; provide processing control information to supporting programs, such as document validators and browsers; add editorial comments to a file
-is NOT: a predefined set of tags, of the type defined for HTML, that can be used to markup documents; a standardized template for producing particular types of documents.
-based on concept of documents
-set up to use markup tags (<…..>)
-can incorporate standard and nonstandard text elements, illustrations, tables
-contain three types of markup: processing instruction, document type declaration, and document instance

Uche Ogbuji. A survey of XML standards: Part 1. January 2004

-XML growing and difficult for beginners to navigate (probably why we have two readings and a tutorial on the subject.
-article is a summary of what the author sees “as the most important XML technologies, and discuss how they each fit into the greater scope of things in the XML world.” The author also recommends tutorials and other useful resources for evaluating and learning to use each technology which a fully clickable

Fourthought develops 4Suite, an open source platform for XML, RDF, and knowledge-management applications. Mr. Ogbuji is a computer engineer and writer born in Nigeria, living and working in Boulder, Colorado, USA.” Seems well versed and knowledgeable on the subject

Extending your Markup: a XML tutorial by Andre Bergholz

-I found this article very easy to read and liked the addition of examples to aid in the overall presentation
-an important aspect of the article was the Nonterminal element Boom example, as we are going to library school
-Article pretty much covers same material as other in this week’s readings, but in a much more concise and plan fashion.

Week 7 Notes

How Internet Infrastructure Works:

-NOBODY owns the internet
-mainly connection of networks, (fun, simple, colourful image)
-beginnings=1969, "grown from four host computer systems to tens of millions"
-not owned but nonprofit group formed in 1992 defines how we use and interact with the Internet.
-Every computer connected to the internet is setup to a network; in each region, a company has a Point of Presence (POP)- place for local users to access the company's network, there is no overall controlling network but several high-level networks connecting to each other through Network Access Points (NAPs).
-Provides example of network and its connections; "The routers determine where to send information from one computer to another. Routers are specialized computers that send your messages and those of every other Internet user speeding to their destinations along thousands of pathways." (fun image of router, switches, and internet)
-Internet Backbone- first one created 1987 by National Science Foundation, basically fiber optic truck lines for transmission of information
- IP Address= unique id number, really in binary but set up decimal number for humans
-1983, the University of Wisconsin created the Domain Name System (DNS), which maps text names to IP addresses automatically
-Top-level domain names, also called first-level domain names, include .COM, .ORG, .NET, .EDU and .GOV
-Networks, routers, NAPs, ISPs, DNS and powerful servers all make the Internet possible
-simple to use, thankfully, the internet can provide information around the world in a matter of milliseconds
-contains links to related articles, naturally from howstuffworks

Dismantling Integrated Library Systems:

Article is about the transition from traditional ILS system to that of a digital form. While the internet may create a better form in time, the transition is proving to be difficult and messy, causing some to be concerned with the loss of information. There are issues of what to choose, vendors, formats, competition, costs. "Some of the best ideas in online library services have come not from vendors but from librarians themselves." This is not surprising since it is the librarian that most work with the system and the patron. Mentions the concept of chicken vs. egg in that no one knows who caused the proliferation of new library automation modules. While these advancements are beneficial to the library and patron seeking information and networked communication and the technology is of a much better quality now than when this article was written, I still have a problem with some resources, such as BlackBoard (courseweb) and their overuse.

Sergey Brin and Larry Page: Inside the Google machine:

-“ Google co-founders Larry Page and Sergey Brin offer a peek inside the Google machine”
-filmed 4/2004, twenty minutes long
-the answer is boxers, haha…- assume joke perhaps based on Clinton campaign interview on MTV where the question was boxers or briefs, haha
-revolving glowing globe display, show data connections
-Las Ketchup in 2002 popularity example
-the Google foundation
-Orkut
-Googlette
-according to comment, Google answer no longer exists
-cult picture funny, I want to work for Google for the sky trip!
-its crazy to think of all the services Google provides, including the phone product that will soon be released

Muddies Point Week 6

Who is in charge of the registration and organization of IP addresses and domain names, once one site goes down or "disappears" can another site take that name?

Week Six Comments

This week I have made comments on the blogs of Rachel, https://www.blogger.com/comment.g?blogID=4331968769876525173&postID=12663501897547687&page=1, and Lindsay, https://www.blogger.com/comment.g?blogID=7943070653086840690&postID=6784704202412259513&page=1

Week 6 Notes

Local Area Network:

-very short account
-Local Area Network (LAN)- " computer network covering a small geographic area, like a home, office, or group of buildings e.g. a school."
-began in late 60s, early 70s by Universities as need for large networks and high-speed interconnections increased
-early systems include: Cambridge University's Cambridge Rings, Ethernet developed at Xeros PARC, and ARCNET was developed by Datapoint Corporation
-transition to personal computers, LAN business
- Smaller LANs- "consist of a one or more switches linked to each other , often with one connected to a router, cable/DSL modem"
Larger LANs- "characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service, and to segregate traffic. Larger LANS also contain a wide variety of network devices such as switches, firewalls, routers, load balancers, sensors and so on"

Computer network:

-Computer network- "group of interconnected computers. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of some types and categories and presents the basic components of a network."
- classified as Local Area Network, Wide Area Network, Metropolitan Area Network based on scale
-can also be classified by connection method
-can be further classified according to the functional relationships which exist among the elements of the network, i.e Active Networking, Client-server, Peer-to-Peer
- may be classified according to the network topology upon which the network is based, such as Bus, Star, Ring, Mesh, Star-Bus, tree or Hierarchical network,
-types: Personal Network Area (PAN), Local Area Network (LAN), Campus Area Network (CAN), Metropolitan Area Network (MAN), Wide Area Network (WAN), Global Area Network (GAN), intranet, extranet, internet
-hardware components: network interface cords, repeaters, hubs, bridges Switches, routers.


Common Types of Computer Networks-Youtube

-Frank Klein, common types of networks
-most common, PAN
-next, LAN, technology advancing quickly
-then WAN, “the how of that is the design of the network”
-MANs usually very big……duh
-I do not have any questions, very general info video
