TRSYN

For a given mono-lingual thesaurus, this function returns the foreign equivalent of a phrase, synonyms of the phrase, and foreign equivalent of the synonyms as recorded in the specified thesaurus.

Note: Foreign language translation is not part of the ISO-2788 or ANSI Z39.19 thesaural standards. The behavior of TRSYN is specific to Oracle Text.

Syntax 1: Table Result

CTX_THES.TRSYN(restab IN OUT NOCOPY EXP_TAB,
               phrase IN VARCHAR2,
               lang   IN VARCHAR2 DEFAULT NULL,
               tname  IN VARCHAR2 DEFAULT 'DEFAULT');

Syntax 2: String Result

CTX_THES.TRSYN(phrase IN VARCHAR2,
            lang   IN VARCHAR2 DEFAULT NULL,
            tname  IN VARCHAR2 DEFAULT 'DEFAULT')
RETURN VARCHAR2;

restab

Optionally, specify the name of the expansion table to store the results. This table must be of type EXP_TAB which the system defines as follows:

type exp_rec is record (
    xrel varchar2(12),
    xlevel number,
    xphrase varchar2(256)
);
type exp_tab is table of exp_rec index by binary_integer;

See Also: “CTX_THES Result Tables and Data Types” in Oracle Text Result Tables for more information about EXP_TAB.

phrase

Specify a phrase to lookup in thesaurus.

lang

Specify the foreign language. Specify 'ALL' for all translations of phrase.

tname

Specify the thesaurus name. If not specified, system default thesaurus is used.

Returns

This function returns a string of foreign terms in the form:

{ft1}|{ft2}|{ft3} ...

Example

Consider a thesaurus MY_THES with the following entries for cat:

cat
  SPANISH: gato
  FRENCH:  chat
  SYN lion
    SPANISH: leon

To look up the translation and synonyms for cat, enter the following statements:

declare
  synonyms   varchar2(2000);
  span_syn   varchar2(2000);
begin
  synonyms := ctx_thes.trsyn('CAT','ALL','MY_THES');
  span_syn := ctx_thes.trsyn('CAT','SPANISH','MY_THES')
  dbms_output.put_line('all synonyms for CAT are: '||synonyms);
  dbms_output.put_line('the Spanish synonyms for CAT are: '||span_syn);
end;

This codes produces the following output:

all synonyms for CAT are: {CAT}|{CHAT}|{GATO}|{LION}|{LEON}
the Spanish synonyms for CAT are: {CAT}|{GATO}|{LION}|{LEON}
