TOPIC: Figuring out and translating the correct terminology you should use in a search is always a challenge. You can become familiar with technical terminology by using a database thesaurus, which is a list of recommended terms. They may be available in print form, in electronic form online, or both. There are a number of thesauri available in the science and technology databases on Dialog. You can retrieve a list of databases on Dialog that have thesaurii using the command: HELP THESAURI.
To determine whether a word or phrase is appropriate as a search term, start by using EXPAND. EXPAND results in an alphabetical listing of the database index roughly beginning at the word or phrase you entered. Look at the RELATED TERMS (RT) column. The word or phrase may have related terms—words or phrases that may represent the same concept, but may not be alphabetically close to the term you entered. To view the related terms EXPAND again, referencing the appropriate R number. At any point, you can select appropriate reference numbers to create sets of the terms.
In this example we want to find current information on algorithms used in “garbage collection,” a technique in computer science to optimize storage drives. We'll use Inspec® (File 2), a comprehensive scientific and technical database.
COMMAND SUMMARY
BEGIN 2
EXPAND GARBAGE COLLECTION
EXPAND E4
EXPAND R2
SELECT R10
SELECT S1 AND ALGORITHM?/TI
TYPE S2/8/1-2
HOW TO...
1. BEGIN File 2, Inspec, which deals with technical and computer-related subjects.
2. EXPAND the keyword(s) to get a listing of all terms with garbage collection and any related terms.
The RT column contains Related Terms with one related term appearing for “garbage collection (computers). |

3. EXPAND the E number with Related terms (E4).
"U" in the Type column means USE (e.g., the preferred term).
The EXPAND on E4 results in a list of RELATED TERMS with “R” numbers.
4. EXPAND R2 to view a more detailed list of available terms.
EXPANDing the Related Terms resulted in finding a classification code covering most of the terms. |
