Three important questions...
What information do you need?
Where should you look for it?
How can you get hold of it?

Search techniqueshttp://www.flickr.com/photos/thomasclaveirole/454394799/
Anatomy of a literature search
Identify resources that cover your study topic
Create a search strategy
Conduct a search using search operators (i.e. AND, OR and NOT)
Check results for relevance
Changes to search strategy needed? From library resources, obtain the items to read
Devise 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
Information from the Library

What are databases and why you need them

Where to look!
The best sources aren’t free!
Key research is published in academic journals, conferences, etc.
search for this material in subscription-only databases
See your subject page for databases
http://www.southampton.ac.uk/library/subjects/ecs/
Access through subject pages:

Key to unlocking the Resources (3)
Key databases
ISI Web of ScienceGeneral science
databaseCitation searching
INSPEC
Compendex
Specialist Computingand Engineering
databases
How to search the databases
Topic search– keywords or phrases– controlled indexing (thesaurus)
terms
Author/title search
Citation searching (Web of Science)
Searching skills
Boolean logic AND, OR, NOT
Symbols varye.g. electron*
Enclose in quotes “black body radiation”
Truncation and wildcards
Phrase searching
Truncation and wildcards
•To find words with a common stem (normally * symbol)
• Aero* will find:
• Aeroplane• Aeroplanes
• Aerospace
To replace a letter in the middle of a word (normally ? symbol)
• Wom?n will find:• Woman• Women
• Colo?r will find:• Colour• Color
Use ‘Select a database’ tab for full details of the databases available on the Web of Knowledge Platform
Or for areas outside ‘Science’
Search Compendex
Click on the drop down boxes to access search options
Time for you to do some work!
In Inspec or compendex, search for:
‘Ontology-based similarity measures developed with regard to the semantic web’
How many results do you get?
20
Repeat the search inputting your query in the following format:
semantic web and ontolog*
How many results do you get now?
20
21
Carry out a new search using the terms ‘web ontology language OR OWL’
Then COMBINE this search with the results of the previous search (TIP: use search history)
What number of results does this retrieve?
21
22
Exercise 2 – Search results
Try the TDNet link for any Item from the last set of results
Try both the TDNet and the ‘Full Text’ link for item displaying both options. What do you notice?
Try both links for item 9
Mark 5 items you think are interesting
Select the ‘Marked list’ and look at the export options
Look at your ‘Search history’ 22
23
Exercise 4 – Searching by author
Search for articles by Harold Chong using the format given on the search screen (Chong H*)
Number of results
Repeat the search limiting the results to those with Southampton in the address (Hint: select address from the drop down menu of one of the search boxes)
Number of results
This last set of results are probably all papers by the Harold Chong we are interested in.

So where else ..?
The Library Website which links to..
WebCat- the library catalogue, for searching for books and journal titles
Electronic journals via TDNet
More resources via the Subject Pages…
Full text & other sources
IEEEXplore
LNCS – Lecture Notes in Computer Science
ACM Digital Library
E-journals and e-books
ECS E-prints and other e-print servers

Internet search engines
There are some good search engines –useful for finding free information
Google Scholar (general academic)
Scirus (scientific information)
ArXiv
Review slide: 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
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
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
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

Not in the library?
