INTRODUCTION:
|
|
|
|
With the plethora of on-line databases in the public and private sectors,
|
|
I feel it is becoming increasingly important to penetrate and maintain access
|
|
to these databases. The databases in question contain data pertaining to our
|
|
personal lives and to our environment, not to mention the tetrabytes of useful
|
|
information that can be directed toward research and personal education.
|
|
|
|
|
|
Who or What is DIALOG?
|
|
|
|
The DIALOG Information Network is a service that links various public and
|
|
commercial databases together for convenience. In the past, when one wanted to
|
|
access LEGAL RESOURCE INDEX, for instance, one would have to dial direct. With
|
|
DIALOG, hundreds of databases are connected via X.25 networks (Tymnet,
|
|
Sprintnet, Uninet, Dialnet) eliminating frustrating searching and outrageous
|
|
long distance telephone bills (before the AT&T divestiture).
|
|
|
|
Further, within this file is a PARTIAL list of databases found on-line.
|
|
Some of the databases are nothing more than periodicals and abstract sources,
|
|
while others provide FullText articles and books. There are over 2500
|
|
periodicals, newspapers, newsletters and newswires on-line in FullText.
|
|
|
|
Here are a few of my favorites:
|
|
|
|
McGraw-Hill Publications On-Line (File624)
|
|
|
|
- Services offer FullText of their Newsletters serving the world-wide
|
|
aerospace and defense industry. Complete text from 30 newsletters such as
|
|
AeroSpace Daily, BYTE, Aviation Week and Space Technology, Data Communications,
|
|
ENR, among others. For more info on the database, when in DIALOG type Help
|
|
News624.
|
|
|
|
PR NEWSWIRE (File613)
|
|
|
|
- PR Newswire records contain the complete text of news releases prepared
|
|
by: companies; public relations agencies; trade associations; city, state,
|
|
federal and non-US Government agencies; and other sources covering the entire
|
|
spectrum of news. The complete text of a news release typically contains
|
|
details or background information that is not published in newspapers. More
|
|
than 8500 companies contribute news for PR Newswire. PR NEWSWIRE is a known
|
|
agent of Corporate Intelligence.
|
|
|
|
DMS/FI MARKET INTELLIGENCE REPORTS (File589)
|
|
|
|
- FullText of World AeroSpace Weekly, covers all aspects of both civil and
|
|
military aerospace activities worldwide.
|
|
- World Weapons Review, very high degree of technical detail and
|
|
perspective. As such, it has special appeal to military professionals
|
|
and users of weapons.
|
|
|
|
Note: The database treats the newsletters as separate Binders. For example,
|
|
to access the World Weapons Review, after connecting to the database,
|
|
type:
|
|
|
|
SELECT BN=WORLD WEAPONS REVIEW
|
|
or whichever newsletter you wish to search.
|
|
|
|
FINE CHEMICALS DATABASE (File360)
|
|
|
|
- The focus of this database is on sources for laboratory, specialty, and
|
|
unusual chemicals used in scientific research and new product development.
|
|
Fine chemicals are relatively pure chemicals typically produced in small
|
|
quantities. The database will provide you with manufacturers and/or
|
|
distributors.
|
|
|
|
DUN'S ELECTRONIC YELLOW PAGES (File515)
|
|
|
|
- Largest database of U.S. businesses available on DIALOG, providing
|
|
information on a total of 8.5 million establishments. Corporate intelligence:
|
|
you can quickly verify the existence of a business. Then you can obtain
|
|
address, telephone number, employee size, Standard Industrial Classification
|
|
(SIC) and other basic information.
|
|
|
|
CURRENT CONTENTS SEARCH (File440)
|
|
|
|
- FullText articles from over 8000+ worldwide journals dealing with
|
|
science and technology.
|
|
|
|
BOOKS IN PRINT (File470)
|
|
|
|
- Access to in-print and out-of-print books since 1979, BIP lets you
|
|
retrieve bibliographic data on virtually every book published or distributed in
|
|
the United States. Plus FullText reviews on the book(s) you have selected.
|
|
See next.
|
|
|
|
PUBLISHERS DISTRIBUTORS AND WHOLESALERS ON-LINE (File450)
|
|
|
|
- PDW on-line will locate virtually any book, audio cassette, software
|
|
publisher, distributor, or wholesaler in the U.S.
|
|
|
|
You now should have an idea of the power and scope of the Dialog
|
|
Information Network.
|
|
|
|
NOTE: Most of DIALOG's Services are now available to certain Research
|
|
facilities, public and private, on CD-ROM. Check your local public and
|
|
university libraries for this service. Of course, MANY of the more
|
|
interesting databases are not available on CD-ROM and must still be
|
|
accessed through the DIALOG network.
|
|
|
|
|
|
Access to DIALOG Services
|
|
|
|
The following on-line services are available from DIALOG Information
|
|
Services:
|
|
|
|
DIALOG
|
|
DIALOG Business (DBC)
|
|
DIALOG Medical Connection (DMC)
|
|
DIALMAIL
|
|
KNOWLEDGE INDEX
|
|
|
|
The logon procedures for the first four are identical and use the same
|
|
service address; procedures for KNOWLEDGE INDEX differ only in the use of the
|
|
KI service address, as illustrated throughout this file.
|
|
|
|
The most common method of access to DIALOG services uses local phone
|
|
numbers for three telecommunication networks: DIALOG's DIALNET, BT Tymnet,
|
|
TYMNET, and SprintNet. For those who live in an area that lacks a local dialup
|
|
for those three networks, you may use the 800 link into the DIALNET for access
|
|
to all DIALOG services except KNOWLEDGE INDEX. This access is not free, but it
|
|
may cost less than dialing long-distance to reach a network node if you live in
|
|
a region without local access. Access is also available through gateways from
|
|
other on-line systems.
|
|
|
|
Access to many DIALOG services is available from countries throughout the
|
|
world and may be accessed from their own Public Data Networks.
|
|
|
|
Dialnet 800-Number Access
|
|
|
|
The two DIALNET 800 numbers are available for connecting to Dialog services
|
|
from anywhere in the 48 contiguous states. Access through these numbers is not
|
|
free.
|
|
|
|
(800)DIALNET 300, 1200, and 2400 b. (w/MNP error checking)
|
|
(800)342-5638
|
|
|
|
(800)847-1620 VADIC 3400 series modems (1200 baud)
|
|
BELL 103 modems (300 baud)
|
|
BELL 212 modems (1200 baud)
|
|
|
|
Note: I have excluded all the dialup numbers for Tymnet and Sprintnet. If you
|
|
don't know how to find those, obtain a file on X.25 nets and I'm sure
|
|
they will be listed somewhere in them.

Logging in to DIALOG or KNOWLEDGE INDEX (KI)
|
|
|
|
After dialing the appropriate number and establishing the connection, you
|
|
must allow a 10-second delay and then enter the letter A (or a carriage return
|
|
or another terminal identifier from the table below) before any further
|
|
response will occur. Then, follow the remainder of the procedures show below.
|

|
|
|
|
|
|
NOTE: I have researched the method of user number and password distribution
|
|
and all user numbers and passwords are generated by Dialog, BUT upon
|
|
receiving a password from DIALOG you may opt to change it. The
|
|
passwords issued from DIALOG are 8 digits long, consisting of random
|
|
alpha-numeric characters.
|
|
|
|
Once you are connected to your default service or file in DIALOG, you can then
|
|
BEGIN one of the other services; for example, to access DIALMAIL, BEGIN MAIL.

- For access in half duplex, enter a < CTRL H > after the "Enter Service:"
|
|
prompt and before entering the word "dialog" or "ki."
|
|
|
|
- Don't hit backspace if you make an error in typing "dialog" or "ki." The
|
|
result will be toggling your duplex, reason being your backspace is usually
|
|
configured to send a < CTRL H > to delete to the left of the cursor one
|
|
space.

Navigating in DIALOG
|
|
|
|
|
|
To begin a search, one would enter:
|
|
|
|
BEGIN xxxx
|
|
|
|
xxxx would be the database file number. All databases found on DIALOG are
|
|
assigned file numbers. The searching protocol used to manipulate DIALOG seems
|
|
at times to be a language in itself, but it can be easily learned and mastered.
|
|
|
|
|
|
DIALOG HOMEBASE
|
|
|
|
I would advise the first-timer to jump into the DIALOG Homebase Menu,
|
|
which provides information, help, file of the month, database info and rates,
|
|
the DIALINDEX, DIALOG Training, and announcements. DIALOG also provides
|
|
subscribers with special services which include dialouts for certain area
|
|
codes. You can begin the DIALOG HOMBASE by typing:
|
|
|
|
BEGIN HOME

Before I continue describing the various methods of searching, DIALOG has
|
|
an on-line master index to the DIALOG databases, DIALINDEX (file 411). It is a
|
|
collection of the file indexes of most DIALOG databases (menu-driven databases
|
|
cannot be searched in DIALINDEX). DIALINDEX can be used to determine the
|
|
number of relevant records for a single query in a collection of files. The
|
|
query can be a single term, a multiple-word phrase, a prefix-coded field, or a
|
|
full logical expression of up to 240 characters. Nested terminology, proximity
|
|
operators, and truncated terms may also be used.
|
|
|
|
You can set the files you want searched by using the SET FILE command.
|
|
Like this:
|
|
|
|
BEGIN 411 (return)
|
|
|
|
SET FILE ALLNEWS (if you want the latest news on
|
|
or hack/phreak busts)
|
|

|
|
|
|
|
Once you have selected a database you can now SELECT the search keyword.
|
|
You set the flag by:
|
|
|
|
SELECT term - Retrieves a set of records containing the term.
|
|
May be used with words, prefix or suffix codes, EXPAND, or
|
|
set numbers.
|
|
|
|
When defining what you are searching for you can use logical operators
|
|
such as:
|
|
|
|
OR - puts the retrieval of all search terms into one set, eliminating
|
|
duplicate records.
|
|
|
|
AND - retrieves the intersection, or overlap, of the search terms: all
|
|
terms must be in each record retrieved.
|
|
|
|
NOT - eliminates search term (or group of search terms) following it from
|
|
other search term(s).
|
|
|
|
Note: Always enter a space on either side of a logical operator.
|
|
|
|
SELECT Examples:
|
|
|
|
SELECT (BICMOS OR CMOS) AND SRAM
|
|
or
|
|
S (BICMOS OR CMOS) AND SRAM
|
|
|
|
- This would generate something like this:
|
|
138 BICMOS <- records containing BICMOS only
|
|
1378 CMOS <- records containing CMOS only
|
|
681 SRAM <- records containing SRAM only
|
|
S1 203 (BICMOS OR CMOS) AND SRAM <- this is what you
|
|
^^ wanted.
|
|
|| DIALOG names your select topic S1, S2... respectively as search its
|
|
databases to make it easier to type. The contents of S1 are 203
|
|
found records containing the keywords BICMOS, CMOS, and SRAM.
|
|
Sometimes S1 is referred to as S(tep) 1
|
|
|
|
PROXIMITY OPERATORS (Select command)
|
|
|
|
(W) Requests terms be adjacent to each other and in order
|
|
specified. -> S SOLAR(W)ENERGY
|
|
(nW) Requests terms be within (n) words of each other and in order
|
|
specified. -> S SOLAR(3W)ENERGY
|
|
(N) Requests terms be adjacent but in any order. Useful for
|
|
retrieving identical terms. -> S SOLAR(N)ENERGY
|
|
(nN) Requests terms be within (n) words of each other and in any
|
|
order. -> S SOLAR(3N)ENERGY
|
|
(F) Requests terms be in same field of same record, in any order.
|
|
-> S SOLAR(F)ENERGY
|
|
(L) Requests terms be in same descriptor unit as defined by
|
|
database. -> S SOLAR(L)ENERGY
|
|
(S) Requests terms be in same Subfield unit as defined by
|
|
database. -> S SOLAR(S)ENERGY
|
|
(C) Equivalent to logic operator AND.
|
|
-> S SOLAR(C)ENERGY
|
|
|
|
PRIORITY OF EXECUTION
|
|
|
|
Proximity operator, NOT, AND, OR
|
|
|
|
Use parentheses to specify different order of execution, e.g. SELECT (SOLAR OR
|
|
SUN) AND (ENERGY OR HEAT). Terms within parentheses are executed first.
|
|
|
|
STOP WORDS (predefined)
|
|
|
|
The following words may not be SELECTed as individual terms. The computer will
|
|
retrieve a set with zero results. They may only be replaced with proximity
|
|
operators, e.g. S GONE(2W)WIND
|
|
|
|
AN FOR THE
|
|
AND FROM TO
|
|
BY OF WITH
|
|
|
|
RESERVED WORDS AND SYMBOLS
|
|
|
|
The following words and symbols must be enclosed in quotation marks whenever
|
|
they are SELECTed as or within search terms, e.g., SELECT "OR"(W)GATE?
|
|
|
|
AND =
|
|
FROM *
|
|
NOT +
|
|
OR :
|
|
STEPS /
|
|
|
|
TRUNCATION
|
|
|
|
OPEN: any number of characters following stem.
|
|
SS EMPLOY?
|
|
RESTRICTED: only one additional character following stem.
|
|
SS HORSE? ?
|
|
RESTRICTED: maximum number of additional characters equal to
|
|
number of question marks entered. SS UNIVERS??
|
|
|
|
INTERNAL: allows character replaced by question mark to vary. One
|
|
character per question mark. SS WOM?N
|
|
|
|
|
|
BASIC INDEX FIELD SPECIFICATION (SUFFIX CODES)
|

A colon is used to indicate a range of sequential entries to be retrieved in a
|
|
logical OR relationship.
|
|
|
|
Examples:
|
|
|
|
SELECT CC=64072:64078
|
|
SELECT ZP=662521:62526
|
|
|
|
|
|
LIMIT QUALIFIERS
|
|
|
|
Limit qualifiers are used in SELECT statements to limit search terms or sets to
|
|
given criteria. Specific qualifiers vary according to database.
|
|
|
|
English language documents /ENG
|
|
Major descriptor /MAJ
|
|
Patents /PAT
|
|

|
SELECT (STRESS OR TENSION)/234567-999999
|
|
|
|
Well that's it for basic searching. Now, how to view the record you have
|
|
selected.
|
|
|
|
Note: Indexes (prefix codes) often differ from database to
|
|
database, often resulting in futile searches. One way to avoid this
|
|
is to make a trip to the local Public or University Library and look
|
|
up the blue sheets for the database you wish to query. Blue sheets
|
|
are issued by dialog as a service to their users. Blue Sheets often
|
|
contain helpful searching techniques ere to the database you are
|
|
interested in. They will also contain a list of Indexes (prefix
|
|
codes) unique to that database only.
|
|
|
|
|
|
VIEWING SEARCH RESULTS
|
|
|
|
|
|

|
|
|
|
|
|
DISPLAY Provides display of results one screen at a time. Use
|
|
D PAGE for subsequent screens.
|
|
Specify set/format/range of items. If range not specified, use
|
|
D to view next record. May also be used with specific
|
|
accession number.

|
|
|
Examples: D 11/6/1-44 <- set/format/range
|
|
D 9/5 <- set/format
|
|
D 7 <- view next.(7 in this case)
|
|
D 637372/7 <- view record 637372/format 7
|
|
|
|
|
|
PRINT Requests that results be printed offline and mailed. Specify
|
|
set/format/range of items. If item range not specified up to
|
|
50 records will be printed. Use PR to print another 50.

Enjoy the DIALOG Information Network. I've found it most interesting.
|
|
This service is a MUST if you are in college or if you just love to learn as
|
|
uch as time permits. It is a proven research tool used by R&D and university
|
|
facilities around the world, as well as a refined corporate intelligence
|
|
information gathering tool kept hidden from the general public by sheer expense
|
|
and "pseudo-complexity." With on-line databases like DIALOG available, there
|
|
is no excuse (besides lack of time) for self-education.
