Three important questions...



What information do you need?


Where should you look for it?


How can you get hold of it?

Where do you look for information?

1.
Google only

2.
Google, some Wikipedia

3.
WebCat

4.
Library Website & WebCat

5.
Specialist Databases

Full
-
text databases


What are they?


Why are they useful?


Which databases are the most useful to ECS?


Still important but limited to Societies and
Publishers own publications


need to find out
what else is being published

4

Which are examples of full
-
text
databases?

5

1.
LNCS


Lecture
Notes in Computer
Science

2.
Web of Science

3.

-
Net

4.

Create a search strategy

Look at your own ‘search statement’ or project topic and
devise a
search strategy

by selecting relevant
keywords or concepts


Break down topic into components


Identify keywords, synonyms, alternative spellings &
related terms


List relevant headings

Then

…put the search strategy into practice in the
different databases and compare the results

Searching skills

Boolean logic

AND, OR, NOT

Symbols vary

e.g. electron*

Enclose in quotes


“black body radiation”

Truncation


and wildcards

Phrase searching

Anatomy of a literature search

Create a search strategy

Identify relevant databases

Conduct a search

Check results for relevance

Changes to search strategy

What is this telling us? …….


PLAN IN ADVANCE

3



Is this an example of a good or bad “search
strategy”?


Semantic web AND (web
ontology language OR OWL)
AND “similarity measure*”



No


It has no truncation and
boolean


Yes


boolean and truncation have
been used


Yes


it has allowed for variants in
terminology; used boolean and
truncation


No


it is too complicated

Where to look!

The best sources aren’t free!


Key research is published in academic
journals, conferences, etc.

Library

Why would you use specialist
databases?

Because ..

1.
Google didn’t work

2.
Need a comprehensive survey
of all the literature that has been
published worldwide

3.
Require full text i.e. actual
articles

4.
Need to find out about new
research the minute is has been
published

5.
Want to use resources available
by just one publisher

How to search the databases


Topic search


keywords or phrases


controlled indexing (thesaurus) terms


Author/title search


Citation searching (Web of Science)

Key databases

ISI Web of Science

General science


database

Citation searching

INSPEC

Compendex

Specialist Computing

and Engineering

databases

Use ‘Select a database’ tab for full
details of the databases available on
the Web of Knowledge Platform

Or for areas outside ‘Science’

boxes to access search
options

Search Compendex

Time for you to do some work!



In Inspec or compendex, search for:


“Examine how teenagers use
social networking sites for
intimacy, privacy and self
-
expression”


How many results do you get?

27

DO the SAME search in Inspec,
Compendex and Web of Science..

…. using these KEY concepts:


social networking sites or SNS


“social networking sites” or SNS


teenager* or youth or young people or
adolescent*


How many results do you get now?

27

25

Note the difference in the
number of results when
using OR and “”

Searching Compendex
-

results

Use the search history to
determine results and
combine searches together

Searching Web of Science

28

Searching Inspec
-

results

29

28


Carry out a new search using any or all of
the following terms

privacy, intimacy or
self
-
expression’


Then COMBINE these terms with the results
of the previous search (TIP: use search
history)


What number of results does this retrieve?

28

Keep reviewing your search by:


improving your search strategy


identify the concepts of your query


List alternative phrases and keywords


Include both narrow and broad terms


Controlled vocabulary


Use truncation/wildcards


Use boolean operators


Identify any key periods of research


Identify any key authors in the field

29

Exercise 2


Search results


Can you
access ALL of these results?


Follow the
TDNet

links to the PDF (where available) for
items from the results of Exercise 1


Try both the
TDNet

and the ‘Full Text’ link for an item
displaying both options. What do you notice?


Mark 5 items you think are interesting


Select the ‘Marked list’ and look at the export options


Look at your ‘Search history’

TIP: We have subscriptions to many journals &
conferences


TD
-
Net will link you to them if available!

books and journal titles

Internet search engines

There are some good search engines

useful
for finding free information




Google Scholar (general academic)



Scirus (scientific information)



ArXiv



Finding the full text


If there is a full
-
text link or TDNet link try it


If not search

WebCat


Journal articles

by the journal title



(use full title not abbreviations)


Conference papers

by the conference title


(for IET/IEEE use IEEEXplore)


Reports

by author and title

If it’s ….


In the library



note the ‘call number’.. Per Q



find the item on the shelves



or follow through the electronic link if there
is one

Recording references



Record the full details of the reference



Record how you found it

Recording your results

Mark relevant references in your search results

Then:


export to reference software


e
-
mail results to yourself


save to a file
