Muddiest Point Unit 12

• I've never been clear on what an RSS feed is visually until this unit, but I don't understand how it's beneficial. It looks like code to me...Whenever I'd click on the RSS option on a site, I thought I was always doing something wrong because it looked just like code, but then on slide 37 an example is shown of RSS feed....I don't know, I just don't really get what it is.

• I really like wiki's. And I'll admit it, I REALLY like wikipedia too! I believe they will always be around and grow in relevance. I believe many are intimidated by this instrument, but what about an encyclopedia, can't information in there be a mistake? Or a scholarly journal, "facts" can be found inaccurate after further study...

Muddiest Point Week 11

Can't all databases be called DL's? While they each have different end goals, at the essence of what they are and how they function seemt he same.

I don't understand the comparison of DL's with search engines....

Muddiest Point Week 10

Bag of word representation does not seem like a very effective method to organize a document in order for it to be found. Unless the single search query were highly specified, I don't see many relevant results being returned. Is there any type of statistical "hit" rate for this method?

It doesn't seem as though all search engines utilize Boolean operators in there basic search field. How is the average searcher supposed to know?

Can you show some examples of a good index and a bad index?

Muddiest Point Week 10

Bag of word representation seems like a bad method. How often is a query submitted that is just looking for a word? Unless the searcher has no idea where to begin and is just jumping in with one specific word, I can't imagine a great deal of benefit in this style of organization.

If you're an average searcher, what's the best clue to tell them if the search system/engine/whatever that they're using utilizes boolean operators because not all do.

Reading Response Unit 10

Web Search Engines Part 1 & Part 2

• interesting that this article calls wikipedia.org a high quality web site. Do they mean fo rthe URL's or info content?
• What is a "hashing function"? How does it enable a crawler to recognize which URL's it's responsible for?
• Crawlers get spammed too, good to know!
• Does a human indexer oversee the indexer?
• When the article gives "the Onion" example as a search query, unless the searcher adds the word satire and or newspaper or something else in that neighborhood, I don't see how the user could be fault the search engine for not returning the desired result.

The Deep Web: Surfacing Hidden Value

• what's the difference between the search engine and a search directory?
• what causes there to be a deep web and a surface web? Is it a choice or a consequent of the content?

Muddiest Point Week 9

• These webpages, I feel like they'll just be taking up space on the web. I don't plan on using mine for anything other then this assignment, what will happen to them?
• It would be very helpful if when you use XML language in the slides you also include what the user would see as a result of the XML language.
