#Term transformation

#############################################################

This file includes exact definitions of term transformations:

*******************************************************

*Transformation: 1

*Parameters: none

*Purpose: delete subfield's signs from the term

*******************************************************

*Transformation: 2

*Parameters: special chars

*Purpose: replace all special chars (occurred in Parameters) by spaces

*Example: term before transformation: (aaa, bbb-ccc)

* parameters: (-,)

* term after transformation = (aaa bbb ccc)

*******************************************************

*Transformation: 3

*Parameters: none

*Purpose: insert logical 'AND' between each two non logical words

* ( logical words are - 'and', 'or', 'andnot')

*Example: term before transformation: (aaa or bbb ccc)

* term after transformation: (aaa or bbb AND ccc)

*Note: the transformation is not case sensitive, so for example,

* if it sees 'or', 'OR', 'oR', 'Or' in the term, it thinks that it's logical 'or'

*******************************************************

*Transformation: 4

*Parameters: none

*Purpose: delete logical 'and', 'or', 'andnot'

*Example: term before transformation: (aaa and bbb or ccc)

* term after transformation: (aaa bbb ccc)

*Note: the transformation is not case sensitive, so for example,

* if it sees 'or', 'OR', 'oR', 'Or' in the term, it thinks that it's logical 'or'

*******************************************************

*Transformation: 5

*Parameters: number

*Purpose: delete short words from the term -

* maximal length of word to be deleted is in Parameters

*Example: term before transformation: (aaaaa xxx y bbbb)

* parameters: (3)

* term after transformation: (aaaaa bbbb)

*Note: if the term contains single word it's left unchanged

*******************************************************

*Transformation: 6

*Parameters: char 'L' or char 'U'

*Purpose: if Parameters is 'U' - put the string to upper case

* if Parameters is 'L' - put the string to lower case

*Example: the term before transformation: (aBcDe oPrs)

* parameters: (U)

* the term after transformation: (ABCDE OPRS)

*******************************************************

*Transformation: 7

*Parameters: special chars

*Purpose: remove part of the term starting from any special

* char from Parameters

*Example: the term before transformation: (Givat Ram [1999])

* parameters: ([(<)

* the term after transformation: (Givat Ram)

*Note: if the term starts from a special char it's left unchanged

*******************************************************

*Transformation: 8

*Parameters: number

*Purpose: delete part of the term after a word number x, where x is in Parameters

*Example: the term before transformation: (aa bb cc dd ee)

* parameters: (3)

* the term after transformation: (aa bb cc)

*******************************************************

*Transformation: 9

*Parameters: empty

*Purpose: leave only first char of the last word of the term;

* leave other words of the term unchanged

* (useful to transform the Author to form understandable by SilverPlatter target)

*Example: the term before transformation (Elliot Thomas)

* the term after transformation(Elliot T)

*Note: do nothing if the term contains single word;

* do nothing it the term contains logical sign 'and', 'or', 'andnot' (not case sensitive)

*******************************************************

*Transformation: 10

*Parameters: char - 'L' or 'R'

*Purpose: if parameters is 'L' add '?' (truncation) to the left end of the term

* if parameters is 'R' add '?' (truncation) to the right end of the term

*Example: the term before transformation: (Elliot T)

* parameter: 'R'

* the term after transformation: (Elliot T?)

*******************************************************

*Transformation: 1

*Parameters: string pattern

*Purpose: Delete all words from the term starting from

* string pattern from Parameters

*Example: the term before transformation: (<The> present state of the jews)

* parameters: (<)

* the term after parameters: (present state of the jews)

*Note: if the term contains single word it's left unchanged;

*******************************************************

*Transformation: 12

*Parameters: empty

*Purpose: Insert coma after first word in the term.

* Useful to transform Author to form understable

* by OE_BRANDEN target

*Example: the term before transformation: (Jackson Michael)

* the term after transformation: (Jackson, Michael)

*Note: if the term contains single word - it's left unchanged

* if the term already contains coma - it's left unchanged

*******************************************************

*Transformation: 13

*Parameters: start string pattern, 'a', end string pattern

*Purpose: Delete all from the term starting from

* start string pattern from parameters and ending by

* end string pattern from parameters

*Example: the term before transformation: (Linden, R <van den>)

* parameters: (<a>)

* the term after transformation: (Linden, R)

*Note: if the term starts from start string pattern and

* ends by end string pattern it's left unchanged

*******************************************************

*Transformation: 14

*Parameters: string

*Purpose: Delete from the term words equal to string from parameters

*Example: the term before transformation: (art - literature)

* parameters: (-)

* the term after transformation: (art literature)

*Note: if the term contains single word it's left unchanged

*******************************************************

******************************************************

*Transformation:15

* Parameters: string

*Purpose: For each word in the term , if the word ends by

* string pattern from parameters, delete this string pattern from the word

*Example: the term before transformation: (modern art-)

* parameters: (-)

* the term after transformation: (modern art)

*******************************************************

*Transformation:PROC16

* Parameters:string

*Purpose: add to the end of term string pattern from parameters;

* do nothing if the term is single word

*Example: the term before transformation (Elliot T)

* parameters: (?)

* the term after transformation (Elliot T?)

*******************************************************

*Transformation:PROC17

*Parameters: empty

*Purpose: If number of words in the term is not equal to 2 – the term left unchanged

* If length of the second word is greater than 2, leave only

* first char of the second word and add '?' to the end of the second word.

* Connect the words by '-'

*Example 1: the term before transformation:(Eliot TS)

* the term after transformation: (Elliot-TS)

*Example 2: the term before transformation: (Eliot Thomas)

* the term after transformation: (Eliot-T?)

*******************************************************

*Transformation:PROC18

*Parameters: string

*Purpose: append to each word of the term (except logical operators ‘and’, ‘or’, ‘andnot’)

* the string from parameters

*Example: the term before transformation: (israel AND history)

* parameters: ([TITL])

* the term after transformation: (israel[TITL] AND history[TITL])

*******************************************************

*Transformation:PROC19

*Parameters: string

*Purpose: append the string from the parameters to the end of the term

* parameters: ([AUTH])

* the term after transformation: (Smith John[AUTH])

*******************************************************

*Transformation:PROC20

*Parameters: empty

*Purpose: remove from the term all words listed in table

* /aleph/a50_5/alephe/utf_files/aleph/a50_5/vir00/tab/tab03

*Example: the term before transformation: (History of medicine)

* parameters: contains word ‘of’

* the term after transformation: (History medicine)

*******************************************************

*Transformation:PROC21

*Parameters: number

*Purpose: cut the term so that it’s length will be no more than number defined in Parameters

* Only complete words are left. If the term is logical expression the result is

* valid logical expression

*Example: the term before transformation: (history AND of AND the AND art)

* parameters: (20)

* the term after transformation: (history AND of)

*******************************************************

*Transformation:PROC22

*Parameters: number1_number2

*Purpose: delete string of characters starting from position number1 in the term

* containing number2 characters, where number1 and number2 are

* defined in Parameters

*Example: the term before transformation: ($$axxxhistory AND art)

* Parameters: (4_3)

* the term after transformation: ($aahistory AND art)

*******************************************************

*Transformation:PROC23

*Parameters: string

*Purpose: if the term contains exactly one word, add the string from parameters

* to the end of the term.

*Example: the term before transformation: (gilbert)

* Parameters: (-?)

* the term after transformation: (gilbert)

*******************************************************

*Transformation:PROC24

*Parameters: string

*Purpose: add the sring from parameters to the beginning of the term

*Example: the term before transformation: (smith john)

* Parameters: ([AUTH])

* the term after transformation: ([AUTH]smith john)

*******************************************************

*Transformation:PROC25

*Purpose: concatenate the words in the term using the string from parameters

* do nothing if:

* - the term contains single word;

* - the term contains logical expression;

*Example: the term before transformation: (reed dorothy)
