Top 10 Tips 03/03/2013 www.rba.co.uk 2PowerPoint Presentation: Google Anything it can find on the web Web sites, blogs, images, videos, podcasts, PDFs, spreadsheets, presentations, discussions Sometimes includes articles from Scholar at the top of the results Author self archived repositories (may NOT be included in Scholar) Google Scholar Research information, patents, legislation (US) from known publishers Open access Institutional repositories Anything that is structured like an academic paper Separate from main Google 03/03/2013 www.rba.co.uk 3Five things you need to know about Google : Five things you need to know about Google 1. Google personalises your search 03/03/2013 www.rba.co.uk 4 Non-personalised search Personalised searchFive things you need to know about Google : Five things you need to know about Google Personalises search based on location past search history past browsing activity activity in other areas of Google e.g. YouTube, Google Reader content from contacts in your personal networks may be given priority what you and others have ‘liked’, g+1 03/03/2013 www.rba.co.uk 5“Un-personalise” your search: “Un-personalise” your search Chrome - New incognito window FireFox - Tools, Start Private Browsing Internet Explorer – Tools, InPrivate Browsing Switch off web/search history Log out of your Google account Clear cookies 03/03/2013 www.rba.co.uk 6Five things you need to know about Google: Five things you need to know about Google 2. Google automatically looks for variations on your terms and omits terms To force an exact match and inclusion of a term in a search prefix it with ‘ intext :’ UK public transport intext:biodiesel statistics “..” around terms does not always work Verbatim – runs your search exactly as you have typed it in Google Scholar – does not drop terms Google Scholar – can still use ‘+’ before a term to force an exact match 03/03/2013 www.rba.co.uk 7Google Verbatim: Google Verbatim Run your search On the results page select Search tools, All results, Verbatim 03/03/2013 www.rba.co.uk 8Five things you need to know about Google: Five things you need to know about Google 3. Google web search does not search everything Two indexes: main, default index and the supplemental index (lower “quality” material) Supplemental index may contain less popular, unusual, specialist material Supplemental index comes into play when Google thinks your search has returned too few results Using advanced search commands and Verbatim seems to trigger a search in the supplemental index 03/03/2013 www.rba.co.uk 9Five things you need to know about Google: Five things you need to know about Google 4. Google changes its algorithms several hundred times a year Some changes are minor and barely noticeable, others are more significant e.g. dropping search terms How Google makes improvements to its search algorithm - YouTube http://youtu.be/J5RZOU6vK4Q 03/03/2013 www.rba.co.uk 10Five things you need to know about Google: Five things you need to know about Google 5. We are all Google’s lab rats Google constantly tests changes on users in “live experiments” Just Testing: Google Users May See Up To A Dozen Experiments : http://searchengineland.com/just-testing-google-searchers-may-see-up-to-a-dozen-experiments-141570 Mostly minor effects on search but sometimes totally bizarre results Google decides that coots are really lions http://www.rba.co.uk/wordpress/2011/02/12/google-decides-that-coots-are-really-lions/ Update on coots vs. lions http://www.rba.co.uk/wordpress/2011/02/21/update-on-coots-vs-lions/ 03/03/2013 www.rba.co.uk 11PowerPoint Presentation: What I see on my screen will not be what you see on your screen, will not be what your colleagues see on theirs, will not be what your users see. Google Scholar more consistent? 03/03/2013 www.rba.co.uk 12Google commands: Google commands Speech marks around phrases or titles of articles “Geochemical evaluation of flowback brine from Marcellus gas wells” Note: if Google finds no documents containing your phrase it will ignore the speech marks Verbatim – runs your search exactly as you have typed it Search tools, All results, Verbatim (see earlier slide) intext: before your term – term must be present and exactly as you have typed it UK public transport intext:biodiesel statistics 03/03/2013 www.rba.co.uk 13Google commands: Google commands Think file format PDF for research documents, government reports, industry papers ppt or pptx for presentations, tracking down an expert on a topic xls or xlsx for spreadsheets containing data Use the advanced search screen or the filetype : command zeolites environmental remediation filetype:pdf nasa dark energy dark matter filetype:ppt nasa dark energy dark matter filetype:pptx annual average global temperature 1960..2012 filetype:xls annual average global temperature 1960..2012 filetype:xlsx 03/03/2013 www.rba.co.uk 14Google commands: Google commands Site search For searching single large sites, or groups of sites by type for example academic, government Use advanced search screen or site: command marcellus gas wells hydraulic fracturing site:psu.edu marcellus gas wells hydraulic fracturing site:edu shale gas hydraulic fracturing earthquakes site:ac.uk shale gas hydraulic fracturing site:gov.uk 03/03/2013 www.rba.co.uk 15Google commands: Google commands Numeric range search Anything to do with numbers and quantities: years, temperatures, weights, distances, prices etc Use the advanced search screen or type in your two numbers separated by two full stops as part of your search world oil demand forecasts 2015..2030 world oil demand forecasts 80..100 mb/d 2015..2030 toblerone 1..5 kg 03/03/2013 www.rba.co.uk 16Google commands: Google commands Words in the title – can be single words or phrases Ensures subject is the main focus of the article Use advanced search screen or intitle: intitle:”diabetic retinopathy” Words in the URL – can be single words or phrases Use advanced search screen or inurl: inurl:”diabetic retinopathy” 03/03/2013 www.rba.co.uk 17Google search options: Google search options Date Restrict your results to information that has been published within the last hour, day, week, month, year or your own date range Search tools , Any time and select an option 03/03/2013 www.rba.co.uk 18Google search options: Google search options Reading level Changes the type of material that is returned Run the search and from the menu above the results select Search tools , All results and then Reading level 03/03/2013 www.rba.co.uk 19Google search options: Google search options 03/03/2013 www.rba.co.uk 20Google Scholar : Google Scholar http://scholar.google.com/ “Google Scholar provides a simple way to broadly search for scholarly literature. From one place, you can search across many disciplines and sources: articles, theses, books, abstracts and court opinions, from academic publishers, professional societies, online repositories, universities and other web sites. Google Scholar helps you find relevant work across the world of scholarly research”. Search all scholarly literature from one convenient place Explore related works, citations, authors, and publications Locate the complete document through your library or on the web Keep up with recent developments in any area of research Check who's citing your publications, create a public author profile 03/03/2013 www.rba.co.uk 21Google Scholar: Google Scholar Does not cover all key journals in all subjects – no source list Top publications for subjects and languages under Metrics link on home page or http://scholar.google.co.uk/citations?view_op=top_venues&hl=en Scholar indexes the full text but you may have to pay to view the whole article Groups different versions of an article together 03/03/2013 www.rba.co.uk 22Google Scholar: Google Scholar Includes open access material, pre-prints, institutional repositories (but not necessarily author self archived repositories) Includes material that is NOT peer reviewed but is structured and looks like an academic article (title in large font, authors, affiliations, abstract, keywords, citations) Pre-prints and IR copies may differ from final published version – charts and images may be redacted because of copyright restrictions 03/03/2013 www.rba.co.uk 23Google Scholar: Google Scholar 03/03/2013 www.rba.co.uk 24 Does NOT use the publishers’ metadata Date and author search looks in the area of the document where those elements are usually found Page numbers, part of an address, data item may be mistaken for publication year Sometimes gets the author wrongCommunicating with postgraduate research students: some themes from the library literature http://www.chuukaku.com/blog/2013/01/communication-with-pgr.html : Communicating with postgraduate research students: some themes from the library literature http://www.chuukaku.com/blog/2013/01/communication-with-pgr.html 03/03/2013 www.rba.co.uk 25PowerPoint Presentation: Jacsó, Péter . “Metadata mega mess in Google Scholar.” Online Information Review 34.1 (2010): 175-191.

For example, an h-index of 20 means that the researcher has 20 papers each of which has been cited 20 or more times Calculated by Scopus, WoS , Google Scholar, Microsoft Academic Search (?) but only for those papers within the database 03/03/2013 www.rba.co.uk 29g-Index: g-Index g-index - distribution of citations received by a given researcher's publications Devised by Leo Egghe in 2006 “Given a set of articles ranked in decreasing order of the number of citations that they received, the g-index is the (unique) largest number such that the top g articles received (together) at least g 2 citations.” g-index - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/G-index 03/03/2013 www.rba.co.uk 30Other indices: Other indices i10 Index i10-index is the number of publications with at least 10 citations e-Index PLOS ONE: The e-Index, Complementing the h-Index for Excess Citations http://www.plosone.org/article/info:doi%2F10.1371%2Fjournal.pone.0005429 03/03/2013 www.rba.co.uk 31Google Scholar h-index: Google Scholar h-index 03/03/2013 www.rba.co.uk 32 Author creates a profile and claims papersGoogle Scholar h-index: Google Scholar h-index 03/03/2013 www.rba.co.uk 33 ScholarHIndexCalculator - mWiki https://www.mat.unical.it/ianni/wiki/ScholarHIndexCalculator Add-on for Chrome (development of new features stopped for Firefox)Google Scholar - Scholarometer : Google Scholar - Scholarometer 03/03/2013 www.rba.co.uk 34 Scholarometer: Browser Extension and Web Service for Academic Impact Analysis http://scholarometer.indiana.edu/ Firefox and ChromeGoogle Scholar - Scholarometer: Google Scholar - Scholarometer 03/03/2013 www.rba.co.uk 35Google Scholar – Publish or Perish: Google Scholar – Publish or Perish 03/03/2013 www.rba.co.uk 36 Publish or Perish - Anne-Wil Harzing http://www.harzing.com/pop.htm Desktop applicationMicrosoft Academic Search: Microsoft Academic Search http://academic.research.microsoft.com/ Journal articles, pre-prints, post-prints, conference proceedings, reports and white papers Free to use but the full text of some papers can only be viewed on payment of a fee to the original journal publisher Automatically computes author g and h index Author may have several different profiles and articles may be assigned to wrong author 03/03/2013 www.rba.co.uk 37Microsoft Academic Search: Microsoft Academic Search 03/03/2013 www.rba.co.uk 38 Note: G and H index have now disappeared – uncertain as to whether they’ll returnMicrosoft Academic Search: Microsoft Academic Search 03/03/2013 www.rba.co.uk 39Institutional repositories: Institutional repositories BASE - Bielefeld Academic Search Engine http://www.base-search.net/ CORE ( COnnecting Repositories) http://core.kmi.open.ac.uk/search DART-Europe E-theses Portal http://www.dart-europe.eu/basic-search.php Institutional Repository Search (IRS) http://irs.mimas.ac.uk/ Open DOAR http://opendoar.org/ RIAN - Pathways to Irish Research http://rian.ie ROAR - Registry of Open Access Repositories http://roar.eprints.org/ 03/03/2013 www.rba.co.uk 40Specialist search tools for research information: Specialist search tools for research information ArXiv http://arxiv.org/ BioMed Central http://www.biomedcentral.com/ Chemistry Central http://www.chemistrycentral.com/ ChemSpider http://www.chemspider.com/ Deep Web Technologies Mednar http://mednar.com/ Science.gov http://www.science.gov/ Science Research http://scienceresearch.com/ WorldWideScience http://worldwidescience.org/ 03/03/2013 www.rba.co.uk 41Specialist search tools for research information: Specialist search tools for research information Europe PubMed Central http://europepmc.org/ Mendeley http://www.mendeley.com/ Open Biology http://rsob.royalsocietypublishing.org/ PhilPapers : Online Research in Philosophy http://philpapers.org/ PubMed Central http://www.ncbi.nlm.nih.gov/pmc/ Scirus http://www.scirus.com/ TechXtra http://www.techxtra.ac.uk/ 03/03/2013 www.rba.co.uk 42 You do not have the permission to view this presentation.
