Expert Search

(October 10, 2000)

What is Engineering Village 2?

 

Engineering Village2 provides instant access to the latest engineering research on the desktop. A powerful way to search across multiple databases, including Compendex (over 5 million engineering literature abstracts), engineering web-site abstracts, patents, engineering handbooks, and industry specs and standards.

 

What is Expert Search?

Expert search was designed for searchers who have been trained in information retrieval and are familiar with Boolean and proximity operators, nested logic, field searching, truncation, and stemming of search terms.  Expert Search was designed for flexibility, precision and control of the search process.

 

Getting Started

Go to http://www.ei.org/engineeringvillage2

 

Institutional Login

If your institution has ID/Password access enter the Ei Engineering Village2 user name and password.  Institutions with IP domain access will enter Engineering Village 2 directly.

 

Reference Services

Ei Village 2 provides a variety of reference services to assist users, "Click on the Reference Services" button.  The following reference services are available:

 

Ask an Engineer

Post questions to a Senior Village Engineer whenever you can't find needed technical information.  Ten senior engineers have agreed to be a resource for users of Ei Village 2.  They are specialists in a variety of engineering disciplines, including manufacturing, materials, electrical engineering, industrial engineering, automation, fluids, TQM, and computer science.  They will respond to questions e-mailed to them usually within 24 hours.  Senior Village engineers will provide information that may include websites, e-mail addresses, or even phone numbers that point to companies, consultants, research institutes, or other information resources.

 

Ask a Librarian

Ei's technical librarians provide search assistance over the phone or via e-mail for Compendex and other Ei Village 2 databases.  They will point to the best reference resources available in the Village or, if possible, locate the piece of information required.

Search questions on engineering topics may also be referred to the Reference staff of Linda Hall Library, an outstanding science and engineering library in the United States. Questions should be sent via e-mail.  Replies will be sent within 24 hours.

 

Network of Experts

The Network of Experts is a searchable database of over 15,000 North American experts in areas of engineering, technology, and applied physics.  The Community of Science produces the database.  It allows searchers to identify experts.  Records in the database provide name and address information, e-mail and telephone addresses and includes a description of expertise and research interests, memberships, qualifications, honors and awards, previous positions, patents, and publications.

Searching Compendex

 

Expert Search for Compendex

Expert Search provides a search box for searching within either single or multiple fields, constructing Boolean or Proximity searches, using truncation and stemming, browsing in indexes for search terms that can be pasted into the search box, When the search strategy is complete click on the Search button.

 

Boolean Operators

Boolean Operators
Operator

                Examples

Use Boolean operators to refine, expand or limit your search.  Use the Boolean operator AND to refine your search, the OR operator to expand your search, and the NOT operator to limit your search.  The NOT operator excludes all records that mention the term.

AND

 

OR

 

NOT

digital signal processing AND impedance

 

boron OR cadmium petroleum

 

transportation NOT motor transportation

 

Note: Multiple terms or phrases from indexes such as Ei Subject Terms, Author, and Publication Title Index may be pasted into the search box.  The search system will place the Boolean operator ”OR” between the terms or phrases.  This default Boolean operator “OR” can then be manually edited to “AND” or “NOT”

 

Proximity Operators

NEAR

 

Proximity Operators
 
Examples

The NEAR operator finds records in which the chosen search terms are close to each other.  Order of relationship is not specified.  Records where the terms are closest will be at the top of the result list if sorting by relevance is chosen.

NEAR

Bridge NEAR piling*

 

The NEAR operator calculates a score for records that contain search terms based on how close they are to each other.  Search terms are AND’ed together within a parameter of 100 words. If the terms are not within 100 words of one another in a given record, that record will not be retrieved.  This proximity operator is designed to make use of the relevance ranking sorting option.  If you choose the relevance ranking option, the records in which the terms are closest will be closer to the top of your results list.  If you choose the Publication Year sorting option, the exact same search will be performed, but your results list will be sorted by year.

 

Note:  When the NEAR operator is chosen, the search system does not look for frequency of terms in a given record.

 

Nesting

 

Nested Logic
 
Examples

To avoid unintended results, use parenthesis to specify the order of Boolean operation.

WN=within

(  )

graph languages AND ((Aalbersberg , I* WN AU) OR (Engelfriet, J* WN AU))

 

Operator Precedence

Nesting allows control of multiple steps of searches by nesting logical grouping of search terms and Boolean operators.  In order to specify the precedence of operators in your search string, use parentheses ().  The systems will process the most deeply nested statement first, and will work its way out.  If search statements are not nested, the system may return unintended results.  In the above example search results would contain either of the authors “Aalberberg, Ijsbrand or Engelfriet, J.  The author search will be executed first and then ANDed with the term  “relevance.”

Truncation and Stemming

 

Note: The Expert Search system does not apply autostemming.  If truncation symbols are not used, the system will interpret the search term exactly as entered.

 

Truncation
 
Examples

The asterisk “*” at the end of a search term is a truncation or wildcard symbol, that allows searching of terms with a variety of endings

à

optic*

(will retrieve such terms as optic, optics, optical, etc).

 

Stemming
 
Examples

The dollar sign “$”, inserted at the beginning of a search term, is used to search for words that have the same linguistic root as the term

$

$compute

(will retrieve compute, computer, computing).

 

Note:  Stemming expands terms only in a very limited manner. For a higher level of control over your search term expansion, use the truncation symbol “*”.

 

Forcing Terms and Characters to Appear in Your Search

Stopwords, operators, and special characters may be stripped out of the search, or interpreted as operators by the system.  In order to force the system to include these characters or words as search terms, you can enclose a phrase in brackets {}.

For example:  {$250}

{High-voltage}

Note:  By using brackets { }, terms are searched exactly as inputted, in the exact order specified.

 

Field Searching

A field is a particular part of a record, such as Ei Subject Term, Title, Abstract, etc.  To search specific field(s) use:

·         WN (within) operator and the field codes listed below. The field codes are listed to the left of the search box.

·          If no field code is specified for the Compendex database, the entire record will be searched.  This contrasts with a Keyword search, which searches the title, abstract and controlled vocabulary fields (Ei Subject Terms).  A Keyword search also includes Identifiers (free language terms assigned by Ei Indexers).

·         The search system does not apply autostemming.

·         If truncation symbols are not used, the system will interpret the search term exactly as entered.

Using Indexes of Terms

 

Use of indexes is strongly recommended to increase the quality of retrieval.  Click on Index of Terms; select the Index, find the term, highlight it; then use Ctrl/c and Ctrl/v to paste it into the search box.

There are five searchable Indexes of Terms within Compendex.  The five indexes are Authors, Author Affiliation, Publication Titles, Publisher Names, and Ei Subject Terms.

 

·         Authors  – An alphabetical list of authors.  An author's name is listed exactly as it appears in the document, although in inverted form.  The author John A. Smith may appear in several variations (Smith, J. A.; Smith, John A.; Smith, John Arnold etc.).  Author names vary due to different practices of journal publishers.

 

·         Author Affiliation – An alphabetical list of author affiliations.  Author affiliation is the institution to which the first author is or was affiliated at the time of publication.  It is recommended to use the Author Affiliation index to browse the index for correct spelling and possible variations of institution names, and to select all variations for the search.

 

·         Publication Title – An alphabetical list of Compendex Journal or Publication Titles.  During the 1970's and 1980's, Engineering Information Inc. used abbreviated publication titles.  For example, the journal IEEE Transactions on Communications was abbreviated as IEEE Trans Commun.  To search by serial title from the 1970's and/or 1980's, select and paste the abbreviated publication title from the index of Publication Titles.  In the 1990's, Ei uses full publication titles.  Alternatively, truncate words in the serial title with an asterisk (trans* AND comm*).

·         Publisher Name – An alphabetical list of publishers.  It is recommended to use the Publisher Name index to browse the index for correct spelling and possible variations.

 

·         Ei Subject Terms – Ei Subject Terms are arranged alphabetically, “Automobile windshields” precedes “Automobiles”.

Note: When records are displayed, Ei Subject Terms are hyper-linked.  By clicking on an Ei Subject Term the system will retrieve records on that subject.

 

Note: The Ei Subject Terms index is also very useful to identify Ei Subject Terms that have changed over time.  In 1993, Ei introduced a new Ei Thesaurus with the following changes.

·         Inverted subject terms were replaced with subject terms in natural word order.

 Old: Robots, Industrial, New: Industrial Robots.

·         Heading/Subheading combinations were dropped.  Instead two subject terms were assigned, requiring the Boolean AND to combine the terms.

Old: Plastics – Applications, New: Plastics AND Application.

·         In some cases, Heading/Subheading combinations were changed to a single term.

Old: Light – Coherent, New: Coherent Light.

·         For comprehensive searches it is strongly recommended that both the old and new Ei Subject terms be used.

 

Sorting

 

Prior to searching, a user may decide on the sorting of search results.  They may be sorted by Relevance or by Publication Date.  The default sorting is by relevance.  If sorting by publication date is wanted, click on the radio button for sorting by date, and search results will show the most recently added records first.

 

Limiting Search by Year

To limit a search by year or range of years use the pull-down menus  “Search From:” to specify the year(s) limit. If a specific year is chosen use the same year in both year boxes.  If a range of years is wanted, enter the starting year in the left column and the ending year in the right column. 1990 to 2000 is the default range of years.

 

Search history

The search history for the current session is displayed below the search box.  The last three searches are displayed.  Click on Expand to see the entire search history.  Click on Contract to display only the last three searches.  When the browser is closed, the search history is deleted.

 

Clearing a Search

After finishing a search on a topic, and before beginning work on a different topic, click on reset to clear a previous search so nothing remains to affect the new search.

Viewing, Saving, Printing and E-mailing Records

 

Search results will be displayed to the right of the search query boxes.  Records are displayed in a short format.

 

From a search results list, one can:

·         Change sorting of retrieved records, if desired, from sorting by relevance to sorting by publication date (the most recently added records will be displayed first.

·         Change record range  (1-25, 26-50, etc.) by clicking on the record range pull-down menu at the top or bottom of each search results page.

 

Viewing Records

·         See individual abstracts or tagged format by clicking on the Abstract link or Tagged Format link under the short record.  A tagged record lists each field separately.  Each field is identified by a two-letter code

·         To change the Viewing format use the pull-down menu "Selected Results:" at the top of the results list.

·         Select the records wanted by checking the box next to the desired records or click on the hyperlink Select All Shown (which selects records currently displayed).  If additional records need to be viewed use the record range pull-down menu to view and select additional records.

·         Use the View pull-down menu and select the desired viewing format: Citation, Abstract, Tagged format.

Click on "View" to see the records in the chosen format.

 

Note: When records are displayed, both authors and Ei Subject Terms are hyperlinked.  By clicking on an author's name, the system will retrieve records by that author.  By clicking on an Ei Subject Term, the system will retrieve records on that subject
