INTRODUCTION

dBase 111+is a powerful general purpose data base management software which can be very easily utilised for all the library activiues including bibliometric studies. The files remain very flexible.

At any time the structure of a file can be changed, by adding or deleting some fields; relation to other files can be set; two or more files can be linked or joined to combine fields or manipulate them. Re- ports can be generated in desired formats for any selective part of a file or by combining data from more than one files. Minor mathematical manipu- lations necessary for bibliometric studies like pre- paring ranked list, finding percentage, getting log values, performing correlation studies etc. can easily be done by writing short programmes in dBase 111+.The tremendous manual labour of bibliometric studies with big databases may be reduced to a great extent by using a computer, as it provides extensive flexibilities of sorting, reorganising and reranking the files in any desired

OBJECTIVES OF THE STUDY

The present study, a part of a broader one was undertaken to develop programmes for citation analysis of references used in some doctoral dissertations in mathematics and of references cited by the articles therein to determine:

a) the main bibliographic forms used;

b) the ranked list of core journals in mathemat- ics and its branches;

c) the normalised ranked list, following Sengupta's correction;

d) the scholars' choice of journals for publishing articles; and

e) the correlation study of what they refer, where they publish and who cites them.

SCOPE AND METHODOLOGY

27 doctoral dissertations on mathematics submit- ted to the University of Burdwan (West Bengal) from 1981 to 1990 and the published articles ap- pended therein, if any, and the references ap- pended to these articles were taken as the input for the study. The Science Citation Index (SCI) from the beginning to 1993 were consulted to know the citations received by these articles/the- ses. References to a single article/book or other document, used more than once, was consid- ered as one. The name of the host document, type of the document, year, number of authors, start- ing page number, self citation, if any, etc. of the total number of 2261 references appended to these theses were noted in each case. A dBaselll+

master file named THREF.DBF was created with the help of a PC-XT for analysis of the data. A five

character alpha-numeric code number (REFCODE) was allotted to each thesis and this was used as the key field in all the related files.

For example, the REFGODE for a thesis of math- ematics submitted in 1987 by Manoranjan J is m87 jm. The other fields used, were for recording document type (REFTP), year (REFYR), number of authors (NOREFRAUTH), name of the journal in case of ajournal reference (JLNAME), first page of the article ( FPAGE ), self-citation, if any (SELFCIT), source thesis year (THYR), citation number (CITNO)(this is one for each reference) and broad subject of the source thesis (SUB- JECT). A two letter character code was used to denote the subject such as, mp =Pure Mathemat- ics, ma =Applied Mathematics, ms =Statistics .The structure of the file THREF.DBF is given in the Appendix-I.

The codes used to record REFTP were, b =Book,c

=Conference/Seminar,j =Journal article,r =Report,t

=Thesis, ta= Table.se'Standard.l =Lecture notes ,un =Unpublished, and m =Others.

The journal abbreviations used in SCI [3] were followed and similar abbreviations were developed for non-SCI titles within 20 character field length.

INSDOC's National Union Catalogue of Scientific Serials in India [2] and Ulrich's International Peri- odicals Directory, 1989 [6] were used to identify any wrongly abbreviated journal title and also to determine the history, country and year of origin of the journal titles.

In studying the references used in the published articles appended to these theses,if any, a sepa- rate file named ARTREF.DBF was created with the REFCODE as the key field, article no.

(ARTNO) as the next field and article year (ARTYR) as an additional field.

A separate file named (THES.DBF) was created to note the full details of every thesis like REFCODE, accession nO.(ACCN), scholar's sur- name (SNAME) and forename (FNAME), year of

submission (THYR), thesis title (THT), name of guides (GDN), no. of pages (NPG), no. of articles (NOART)and subject. Another file named CITREF.DBF is created to npte the citations re- ceived by the articles written by the scholars. The fields included are REFCODE, ARTNO, citation . type (CITIP), citing author (AUTH), name of the

citing journal (JLNAME), citing year (REFYR), first page of the citing article (FPAGE), and year of publication of the scholar's article that has received the citation (ARTYR). The code used to record CITIP was 0 = no citation, 1 = no self citation, 2

= author self citation, 3 = guide self citation, 4 = journal self citation, 5 = author &journal self cita- tion, 6 = author &guide self citation.

Another file named THART.DBF was made to record full bibliographic details of the articles re- ferred to in the theses. In addition to the biblio- graphic information, there are some fields like AUTHNO (= number of authors of the article), PAGENO (number of pages) and REFNO (=no of references in the article). The structures of the da- tabases are given in the Appendix-I.

ANALYSIS OF DATA

The softwares developed to analyse various as- pects of the study are given as Appendix II. The operational aspects of the software are provided inAppendix III.This software may be used for simi- lar bibliometric studies.

Subject-wise Distribution of Theses

The subject wise distribution of the theses, av- erage references per thesis (ART) and average reference per page of thesis (ARP) are shown in Table 1. The ART of all the theses is 83.7. ART of pure mathematics is only 44.1. It is 100.8 for ap- plied mathematics and 117.33 for statistics. The ARP is 0.5016 for all the theses. It is 0.34 for pure mathematics, 0.55 for applied mathematics and 0.61 for statistics.

Bibliographic Forms was used in pure mathematics. Journals are used more in pure mathematics whereas, more books are used in statistics (17.33%). It was found that journal articles accounted for 80.01 % of the total literature whereas, books were 14.86%.

Variation in the use of bibliographic forms of lit- erature in pure and applied mathematics and sta- tistics is evident from Table 2. No report literature

When the articles' references are counted con- sidering one thesis as an unit and counting one reference appearing in several articles of one the- sis as one (whereas two articles may relate to two Chapters of a thesis and a reference appearing at

the end of two chapters are taken as one only), there are 81.7% journal references and 16.52%

books. Conference and thesis are used very little in article references accounting for 0.45% each (Table 3).

However, when the study is made taking individual ' articles as units and same reference appearing in two articles are counted twice ( as it is always done in case of citation analysis of journal articles), it is observed that 15.56% books and 82.22% jour- nal references are used.

The study with references of the few selective theses to which articles are appended ( for which we studied under artref ), showed 78.58 % refer- ences for journal articles and 16.31 % for books (Table 3).

Vol43 No 3 September 1996

Thus, the result of any thesis study will differ from that of journal articles' study due to

i) selective use of references in journal articles for want of space; and

ii) appearance of several articles based on a the- sis , many references of which may be given in more than one article but they may appear only once in the thesis, particularly when the list of references is given at the end of the thesis.

Ranked List for References back upto 1961 the quantum of published literature in the new pe- riodicals is limited by the period for which they have been in existance." To reduce the gain of long run titles for their very old issues, a short list of references was considered back upto 1961 only (20 years from the earliest year of source docu- ment - 1981) (Table 8).

According to Sengupta [4], "in ranking list based on total number of citations irrespective of chro- nology, the ranking of the newly established peri- odicals may not be an accurate index of demand or usefulness to the research workers because

In comparing the two lists (Table 4 & 8), it is ob- served that there is minor change in rank position for most of the journals. New journals have gained in position and the old ones have lost.

Some major changes as revealed in the study are:

P ROY SOC A has gone down to rank posi- tion 19 from 6,

P LOND MATH has gone down to rank posi- tion 22 from 10,

ANN MATH-.STAT has gone down to rank po- sition 24 from 13.

PHI T ROY A is no more in the list that had 25th rank position with 11 citations.

Sengupta's Weightage Formula

Sengupta [4] has provided the weitage formula as

(1)

n n

for correcting citations (to avoid the problem of newly emerged important journals getting less ci- tations only because of their short age). He has shown while explaining his formula

"Y2-Y1 = 1970-1946 = 25 and Y2-Y3=1970-1968=3"

where Y1=1946,Y2=1970and Y3=1968.lt is implied that, these will be Y2-(Y1-1} and Y2-(Y3-1}.

Then the formula will be :

C1= C. (2)

n n

Where, C = number of citations enumerated C1 = corrected (We would say

Normalised) no. of citations Y1 = the begining year for which the ci-

tations are taken into consideration (1961 in this study).

the year upto which the source documents are consulted for counting <;itations (1990), the begining year of the source documents from which counting of citations started (1981)},

n = the number of years during the period Y1to Y2 (1961 t01990) for which the journal had been in existence, and

n, = the number of years during the period Y3to Y2(1981 to 1990) for which the journal had been in existence.

Y3

=

In this study,{Y2-(Y1-1}} = {1990-(1961-1} = 1990- 1960 = 30,

and

{Y2-(Y3-1}} = {1990-(1981-1} = 1990- 1980::: 10.

30 10

Hence, C1=--.--

n n

The factor ~ corrects the smaller quantum of literature available from journals starting publica- tion after 1961 and the factor ~ for the shorter period covered by enumeration in' respect of jour- nals starting publication after 1981.

The accumulation of pre -1961 literature is omit- ted in case of long established journals by setting the cut-off year to 1961 as stated earlier.

The normalised ranked list is given in Table 9 (a short list upto normalised citation no.8 is given here for want of space). The journal'Appl Sci Res A' having enumerated citation nO.8 (sl no.40 in Table 8) get normalised citation 48.00 and has come to (sl nO.5 in Table 9).

CITATION ANAL YSIS

OF

The correlation co-efficient of the journals of re- lated thesis references and the journals where Surdwan University (S.U) scholars published their articles is fdund to be 0.2794 . It is strange enough to note that the correlation co-eficient of the ar- ticles' references and the journals where the ar- ticles are published is only 0.0095. This again shows that the theses references give more real picture of scholar's choice of journals. The corre- lation co-efficient of the theses references and the journals that cite the articles of S.U. scholars is found to be only 0.0858.

Journals Where B.U. Scholars Published Their Articles

A ranked list of journals where mathematics ar-

ticles are published by B.U. scholars is given in Table 11. Tables 12, 13 and 14 give the list of jour- nals where articles of pure mathematics, applied mathematics and statistics are published.

On checking the 20 journals where at least two articles have been published, it is found that 9 are of Indian origin. Thirty one out of sixty four articles are published in Indian journals. On comparing Table 1~ with Table 4 it was found that most of the journals where articles have been published were also covered in the reference. However, more than ten journals of Table 11 have got less than 5 refer- ences each in Table 4. Many articles are published in low cited journals, may be to get a quick media for easy publlcation.

Who Cites the Articles of B.U. Mathematics Scholars

majority of the journals are of foreign origin. The obvious reason is that the study is based on Sci- ence Citation Index, where the Indian journals are very poorly represented. A majority.of the citations from Phys. Rev. A are actually received by only one author for an article published in Phys. Rev.

itself.

Table 15 shows the ranked list of journals that cite the articles of S.U. mathematics scholars. In comparing the journals that cite the articles pub- lished by the S.U. physics scholars, it is found that

CONCLUSION

The work of oitation analysis, namely determining the main bibliographic forms used in any litera- ture, ranking of journals, normalised ranking based on corrected citation number according to Sengupta's formula, and correlation study of dif- ferent lists etc. can be done with great ease with the help of the given programmes based on dBASE 111+.The results of citation study based on the- sesreferences differs from that based on journal articles' references. References given in the the- ses represent more exhaustive picture of schol- ars' journal requirements.

Average reference per page of thesis is found to be lowest in pure mathematics (0.34), more in applied mathematics (0.55) and highest in statis- tics (0.61). Journal articles constitute 80% of total literature used in mathematics. To satisfy 80% of journal requirements, 29 journals in statistics, 38 journals in pure mathematics and 64 journals in case of applied mathematics are needed.

APPENDIX 111

SOFTWARE DETAILS &HANDLING/INVOKING THE SOFTWARE

The software is to be invoked by the command .00 BIBLIO (See Prog.1)

This will ask to enter the data base name on which towork.

On typing the data base name THREF, amenu with seven alternative choices will appear on the screen. Pressing the number attached against the choice will invoke the relevant programme. Required files should be present on the default disk.

Bibliographic Forms

For grouping the references according to their bibliographic forms, '3' is to be pressed from the opening menu. The DOCTYPE.PRG programme (Appendix 11.2)is used for the purpose. It gives the total number and percentage of the distribution of references of different bibliographic forms used. The programme is made flexible by using the macro variable '&filename'. On running the programme, it will ask for the' data base name? 'to be processed.

On typing the database name 'THREF' and pressing 'Enter' Key it will work on that file and give the output on the screen and also in a text file named thref.txt .This .txt file may be further edited through any word processor like Word Star.Jt desired. In case, a direct print out is desired, after making the printer ready, 'y'is to be pressed when the screen displays 'IS PRINT OUT NEEDED? (Y/N)-'

For making the study with subject groups like pure and applied mathematics and statistics, and also period groups of theses (1981-85 and 1986- 90),the THREF.OBF file was divided into subject wise parts ofMAREF.DBF,MPREF.DBF and MSREF.OBF having references of applied and pure mathematics and statistics with the help of commands like. USE THREF or COpy TO MAREF FOR SUBJECT ='ma' etc.

The references were also divided into groups of year of submission (thyr) of theses from 1981 - 1985 and 1986 - 1990 in THREF85.0BF and THREF90.0BF with the commands:

.USE THREF

.COPY TO THREF85 FOR THYR<1986 .COPY TO THREF90 FOR THYR>1985

Ranking of Journals

For preparing ranked list of journals used in the references '4' is to be pressed from the opening menu. The RANKING.PRG programme (Appendix 11.3) is used for the purpose. Two blank data base structures TEST.OBF and RJLlST.OBF as shown in the Appendix are to be in default disk while running the programme. On running the programme, it will ask for the data base name to wrok with. On typing the data base name, say 'thref', it will process the THREF.DBF file and prepare another data base named THREFR.DBF giving the ranked list of journals with columns like SLNO RANKNO JLNAME CITNO CUMUL_NO PERCENT CUM_PERCEN.

A print out of this ranked listcan be taken with the command:

.USE THREFR.OBF .LIST OFF TO PRINT

One may have a better list with the help of a predefined REPORT FORM with headings etc.through the commands .USE THREFR

.CREA REPO JLLlST

and then defining the desired output format andsubsequently, running the command like .USE THREFR .REPORT FORM JLLlST TO PRINT One may have a disk copy of this list as a text file also to merge it with some text or to edit it , by REPORT FORM JLUST TO THREFR. Ranked List for References Back up to "i61

A short list of references back upto 1961 was prepared with the help of the command

.USE THREF .COPY TO THREF61 FOR REFYR>=1961.

Then, using the ranking programme, the ranked list THREF61 R was prepared for journals back upto 1961.

Sengupta's weightage fprmula and its programme

For getting the' normalised ranked list of journals with corrected citation number of each journal, 5 is to be pressed from the opening menu. The NORMCIT.PRG programme (Appendix 11.4) is used for the purpose. Year of starting (SYR), and year of closing (EYR) of each journal were noted in a file JUST.DBF (Appendix) consulting Ref 2 and 6.When, the NORMCIT.PRG programme (Appendix 11.4)is run on a file to get a ranked list of journals according to their normalised citation numbers, the JUST.OBF file andthe blank structure of NJUST.OBF (Appendix) should be present in the default disk.

The normalised citation number is named 'ncitno' to distinguish It from 'citno'. The programme was run on THREF,OBF file, CORRELATION STUOYThe correlation analysis was made based on the formula mentioned in the text

For doing correlation study between any two journal lists, '6'is to be pressed from the opening mem"',e ~(jHn.pn.:;(Appendix 11.5) programme is used for the purpose, A blank file named COR.OBF as shown in Appendix should beI."~.;ent in the working disk while running the programme, The CITNOs of the first journal list will be renamed as CIT2 and those ofthe 2nd jou,'1al list will remain as CITNO. Then, the correlation coefficient of CfTNO and CIT2 (number ofoccurrance of the titles inIn:,h·yO listo; references) is calculated. with the help of the

CORR.PRG programme •
