  1. Electronics and Computer Science Information Resources October 2012 Fiona Nichols

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

  3. Where do you look for information? • Google only • Google, some Wikipedia • WebCat • Library Website & WebCat • Specialist Databases

  4. 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

  5. Which are examples of full-text databases? • LNCS – Lecture Notes in Computer Science • Web of Science • TD-Net • IEEEXplore • ACM Digital Library • Compendex

  6. Examples of Full text sources • IEEEXplore • LNCS – Lecture Notes in Computer Science • ACM Digital Library • E-journals and e-books • ECS E-prints and other e-print servers • Patents • Standards

  7. PLAN IN ADVANCE

  8. 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

  9. Searching skills Truncation and wildcards Phrase searching Boolean logic Symbols vary e.g. electron* AND, OR, NOT Enclose in quotes “black body radiation”

  10. Anatomy of a literature search Check results for relevance Identify relevant databases Create a search strategy Conduct a search Obtain the items from library resources Changes to search strategy needed?

  11. Literature searching basics – ScHARR Library Sheffield • www.youtube.com/watch?v=QlgWG10RMgg&feature=youtube_gdata_player • What is this telling us? ……. • PLAN IN ADVANCE 3 3

  12. Is this an example of a good or bad “search strategy”? 9 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

  13. 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 6

  14. Information from the Library (1)

  15. http://www.southampton.ac.uk/library/subjects/ecs/ Access through subject pages:

  16. Access the Resources via Databases 7 (3)

  17. Why would you use specialist databases? Because .. • Google didn’t work • Need a comprehensive survey of all the literature that has been published worldwide • Require full text i.e. actual articles • Need to find out about new research the minute is has been published • Want to use resources available by just one publisher 10

  18. How to search the databases • Topic search • keywords or phrases • controlled indexing (thesaurus) terms • Author/title search • Citation searching (Web of Science)

  19. Key databases ISI Web of Science INSPEC Compendex Specialist Computing and Engineering databases General science database Citation searching

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

  21. Or for areas outside ‘Science’

  22. Click on the drop down boxes to access search options Search Compendex 25

  23. 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?

  24. 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 27

  25. Searching Compendex - results Use the search history to determine results and combine searches together Note the difference in the number of results when using OR and “” 25

  26. Searching Web of Science - results

  27. Searching Inspec - results

  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 28

  29. 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

  30. 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! 29 29

  31. So where else ..? Check the Library Website for links to.. • WebCat- the library catalogue, for searching for books and journal titles • Electronic journals via TDNet • More resources via the Subject Pages…

  32. What is TD-Net? • The Library Catalogue • Full-text article database • Can find articles of electronic journals we subscribe to • Gives coverage of UofS Libraries print journals • Gives coverage of electronic journals held by UofS Libraries 9

  34. Internet search engines There are some good search engines –useful for finding free information • Google Scholar (general academic) • Scirus (scientific information) • ArXiv

  35. 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

  36. 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

  37. Recording references • Record the full details of the reference • Record how you found it

  38. Recording your results Mark relevant references in your search results Then: • export to reference software • e-mail results to yourself • save to a file

  39. 60

  40. ECS allowance Not in the library? • Request an Inter Library Loan (ILL)

  41. Other search features

  42. Citation Searching Earlier articles More recent articles

  43. Exercise 3 – Citation searching Taken from the annotated bibliography - choose a paper and search the Cited Reference Search in the Web of Science e.g. Shadbolt, Nigel; Berners-Lee, Tim; Hall, Wendy; (2006) The semantic web revisited. IEEE Intelligent Systems, 21 (3), 96-101 Conole, Grainne, de Laat, Maarten, Dillon, Theresa & Darby, Jonathan (2008) Disruptive technologies, pedagogical innovation: What’s new? …. Computers & Education, 50, 511-524 30 30

  44. How many times has this paper been cited by others? • How many papers does the Author cite? • How many related references are there? • Look to see how relevant they are.
