Caution: In CA/HCA/CAplus/HCAplus/ZCA/ZCAplus the charges for each SELECT are considerable (for fields from
both patent or non-patent documents). Consider preferring ANALYZE.
Note: To create patent statistics including graphical representations the ANALYZE PLUS function of STN Express is
most useful.
26.5 Displaying a results table TABULATE
By using the TABULATE command the data from two fields of an ANALYZE result can be displayed in a tabular
format (this goes also for an already edited result). This way it is possible to see e.g. a list of patent assignees and the
number of their applications over time.
When entering a TABULATE command it has to be specified whether the result is to be displayed in a tabular format
or as a delimited list (for later processing by a spreadsheet or presentation program, e.g. Excel). It is not possible to
get both types of display by just one TABULATE command.
Tabular format:
=> TABULATE L2 PA PRY
Delimited format:
=> TABULATE L2 PA PRY DELIMITED
For the tabular format again there are two options:
Default format
GRID
format displays a two-dimensional table, displaying the terms of the primary display code in rows and the terms of
the secondary code in columns. The number of documents for each combination of terms is displayed in the
respective intersection.
=> TABULATE L2
DISPLAY AS GRID FORMAT (N), Y, OR ?:Y
ENTER PRIMARY DISPLAY CODE OR (?):PA
ENTER SECONDARY DISPLAY CODE OR (?):PRY
DISPLAY PRIMARY (TOP 10), ENTIRE OR ?:.
PRIMARY SORT ORDER (CURRENT), DOC, ALPHA, OR ?:DOC
