1. Internet Search
When you search information on Internet,
keep the following in mind.
A lot of online information is not trustworthy.
→
Information found by Internet search is not everything.
→
Do not rely on only top 10 items in Google search.
Example 1.1:
What is the origin of the word "news"?
Many people circulate a groundless rumor such that "news" is an acronym of
the phrase "north, east, west, south"
because news is information from all over the land.
Even some people who are native English speakers post this false information on Internet.
If that were true, then the order of the 4 directions should be
either north, east, south, west
or north, south, east, west
that derive "nesw" or "nsew" instead of "news".
The ordering of north, east, west, south
does not logically sound right.
Remark 1.1:
When you look up an autheticated dictionary,
you find that the origin of the word "news" is
a plural form of the word "new" which came from Greek.
You may wonder why the adjective "new" has a plural form.
In English, nouns have plurals, but adjectives do not.
However, in some Romance languages such as Greek,
adjectives do have plurals.
Example 1.2:
When you try to find information about the following,
it is not easy to find what you really expected
in a reasonable amount of time.
Assume that you has chosen a research topic for your Bachelor thesis
to be a method of freezing & thawing organs for transplants.
It will be a breakthrough in medicine
once iPS (induced Pluripotent Stem) cell technology
will enable regeneration of vital organs
(such as a heart, liver and lung).
Review 1.1:
Determine whether information of the following URL is trustworthy.
http://www.improbable.com/airchives/classical/cat/cat.html
Review 1.2:
Look for information about programming X-ray beams of a
CyberKnife.
Search Engines Used in English-Speaking Countries
Google is so dominant that people tend to consider the following though,
you must keep in mind that such a tendency is sometimes a misconception.
Information highly ranked by Google is trustworthy.
Anything not ranked in a few dozens of top items by Google is disregarded.
Anything not found by Google does not exist.
To locate information that you are seeking for,
you need to learn how to express a query with keywords and phrases.
e.g., a dash "-" followed by a keyword excludes web pages including the keyword from search results
and "site:" followed by a domain name or a website narrows search to the specified domain or website.
The following provide informative tips on composition of queries on Internet.
Review 1.3:
Related to
Example 1.2
above,
compose a query for searching information on iPS.
2. Screening for Trustworthy Information
As was mentioned in the
above section,
there are a number of websites and Web pages that are fallcies and/or misleading.
The others are malicious such as frauds and misleading attempts.
To select true and accurate information from websites and/or Web pages
found by Internet search,
we need to acquire a skill for evaluating them.
The following are informative tips on evaluation of online information
and deciding which are trustworthy.
Example 2.1:
Content farms such as
examiner.com
and websites containing user-generated content
such as
Demand Media
are not necessarily trustworthy.
Example 2.2:
Many websites try to gain revenues from advertisements.
Review 2.1:
Assume that you need to write a research paper on the affects of alcohol on verbal skills.
Search with keywords "alcohol," "verbal skills," and "drinking" on Internet.
Then, identify trustworthy and useful sources of information.
3. Publishing Online Documents
CS major students should be familiar with publishing information via Internet
in the following forms.
- Web Pages
- Blog
- LinkedIn
- Facebook
- Twitter
etc.
There are two critical factors that decide the quality of online documents.
- Technical Writing
- Organization of Content
They will be discussed in the next topic "Written Communication."
Remark 3.1:
Do not overuse programming techniques in creation of online content.
Avoid latest technology (often buzz) to
show off technical skills and make what techies think is cool.
For example, carousel slides were once popular in creation of Web pages
whereas they are now perceived poorly from a viewpoint of UX (User Experience) design.
