Outline for the session Google vs Google Scholar Five things you need to know about Google Advanced search techniques for research information Google Scholar Other specialist tools Homework! Top 10 Tips 25/02/2013 www.rba.co.uk 2

PowerPoint 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 25/02/2013 www.rba.co.uk 3

Five things you need to know about Google :

Five things you need to know about Google 1. Google personalises your search 25/02/2013 www.rba.co.uk 4 Non-personalised search Personalised search

Five 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 25/02/2013 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 25/02/2013 www.rba.co.uk 6

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 25/02/2013 www.rba.co.uk 7

Google Verbatim:

Google Verbatim Run your search On the results page select Search tools, All results, Verbatim 25/02/2013 www.rba.co.uk 8

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 25/02/2013 www.rba.co.uk 9

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 25/02/2013 www.rba.co.uk 10

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/ 25/02/2013 www.rba.co.uk 11

PowerPoint 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? 25/02/2013 www.rba.co.uk 12

Google 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 25/02/2013 www.rba.co.uk 13

Google 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 25/02/2013 www.rba.co.uk 14

Google 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 25/02/2013 www.rba.co.uk 15

Google 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 25/02/2013 www.rba.co.uk 16

Google 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” 25/02/2013 www.rba.co.uk 17

Google 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 25/02/2013 www.rba.co.uk 18

Google 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 25/02/2013 www.rba.co.uk 19

Google 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 25/02/2013 www.rba.co.uk 21

Google 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 25/02/2013 www.rba.co.uk 22

Google 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 25/02/2013 www.rba.co.uk 23

Google Scholar:

Google Scholar 25/02/2013 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 wrong

Google advanced search:

Google advanced search Use advanced search screen or commands as follows: + sign before a search term to force an exact match, for example + norne “....” around phrases for example “environmental remediation” intitle : to search for a single word in the title, for example intitle:zeolites environmental remediation allintitle : to search for all of your terms in the title, for example allintitle:zeolites environmental remediation author: to search on an author’s name, for example zeolites environmental remediation author:rhodes site: to limit your search to specific institution for example marcellus shale site:psu.edu Commands can be combined for a precise search, for example allintitle:marcellus shale author:wolford site:psu.edu 25/02/2013 www.rba.co.uk 28

h-Index:

h-Index h-index developed in 2005 by Jorge Hirsch, University of California in San Diego Attempts to quantify productivity and apparent scientific impact of a scientist. “A scientist has index h if h of his/her Np papers have at least h citations each, and the other ( Np − h) papers have no more than h citations each”. 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 25/02/2013 www.rba.co.uk 29

g-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 25/02/2013 www.rba.co.uk 30

Other 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 25/02/2013 www.rba.co.uk 31
