From isidro at CINDOC.CSIC.ES Mon Apr 2 08:24:05 2001 From: isidro at CINDOC.CSIC.ES (Isidro F. Aguillo) Date: Mon, 2 Apr 2001 14:24:05 +0200 Subject: ABS: Thomas,Webometric analysis of departments of librarianship andinformation science Message-ID: SIGMETRICS provides a valuable insight about the current bibliograpy in scientometrics and related topics, including both abstracts and cited references extracted from ISI products. The recently message about Willett`s article about "Webometric analysis of departments of librarianship and information science" published in Journal of Information Science offered the full list of references of this paper as extracted by ISI directly from the original paper. It is surprisingly that references from electronic journals only cite the URL address and the accession date not the original year of publication. There is no mention of the name of the publication and the accession date is over three years after publication date. With this behaviour it will impossible to make scientometric analysis of the ejournals impact and any intention to derive indicators from databases will be faulty. This is not the fault of ISI as I checked that original paper and ISI indexers extract the data as showed in the references. We suggest more caution in the citation of electronic material, specially when peer-reviewed journals are involved. We are also interested in obtaining information about impact factor "calculations" of ejournals and related studies published in paper oe in the web.

Card payment will be accepted for registrations on the appropriate form with the name of the cardholder, number of card, expiry date of card and cardholder -------------- next part -------------- 's signature. We will acknowledge receipt of payments once the cheque, money order or card verification process is complete. Because of the delay in getting the card payment approved, we have extended the early payment discount up to the end of May 31st. The higher (late payment) rate will now apply to those who pay on or after June 1st. Registrations are now being received. We do urge all who intend to participate in the Conference to register with us so that we have some idea of the numbers of people we must cater for. We are hoping for a good attendance of people including interested participants as well as those whose papers and posters are to be presented. The Australian Organising Committee has planned concurrent sessions for Monday, Wednesday and Thursday, and two special plenary sessions on Tuesday (journal impact measures and use) and Friday (cybermetrics/webometrics and methodology). There will also be a chance to get to know each other better, to network and to form plans for future collaborations at the various social events - for example, on Sunday during the Registration period at an Aboriginal Smoking Ceremony to welcome Conference Delegates to the UNSW campus, on Monday evening at the Derek de Solla Price Award ceremony (the Scientometric Laureates), at the formal Conference Gala Dinner (Tuesday evening), and during a twilight tour of Sydney Harbour by ferry on Wednesday. We look forward to your registrations and to meeting you all here in Sydney in July.

We also rank articles by number of citations using regressions controlling for time since publication, journal, and subject area. To summarize a few of our results: citations per year peak at 4 years after publication, and an article receives half of its expected total lifetime citations after 4.6 years; appearing first in an issue is a significant advantage; international law articles receive fewer citations; jurisprudence articles are cited more often; articles by young, female, or minority authors are more heavily cited. Articles with shorter titles, fewer footnotes per page, and without equations have significantly more citations than other articles. Total citations generally increase with an article's length, but citations per published page peak at 53 pages.

Authors (or law review editors) might think that they could increase their citations if they just publish longer articles or shift toward publishing constitutional law pieces. Such inferences are fraught with peril. The fallacy of aggregation suggests that just because long articles have tended to be cited more in the past does not mean that journals should force authors to add 10 pages of pablum to their articles in order to generate more citations. Still, with regard to an individual article, it is hard to resist thinking that affixing a shorter title might not increase the number of citations. Citations analysis also unavoidably has a gossipy and at times tawdry aspect. We are drawn to citation rankings -- reading and discussing them around the water cooler -- but we are simultaneously repulsed by them -- criticizing their meanings (especially when we are excluded). Given the endemic identification problems discussed above, extreme modesty is in order. Indeed while there is a certain ineffable value to these studies, we wonder whether this value justifies the time and journal pages devoted to the subject. APPENDIX Description of the Data Our source of citations data was the SSCI compiled by the Institute for Scientific Information. We extracted citation, self-citation, and citation by citing year counts for every piece in the Harvard, Stanford, and Yale law reviews. The electronic version of the SSCI we used covered the period from 1980 to 1997, with only partial coverage in the first and last years. We used all of this citing information but limited the scope of cited pieces to the period from 1980 to 1994-95 volume of each journal. Next we examined in hard copy each piece on the list to determine how the journal classified it. We eliminated student-written work (notes, book notes, case notes, developments in the law, and so forth) tributes, corespondence, and book reviews. The remaining pieces included all articles, essays, commentaries, Harvard forewords, and symposium pieces. In order to maintain a minimal degree of comparability among the pieces, we also eliminated all pieces with fewer than five pages and pieces shorter than 10 pages with no citations. In the end, we were left with a total sample size of 979 pieces, including 530 articles. ------------------------------------------------------------- (c) ISI, Reprinted with permission Please visit their website at www.isinet.com ------------------------------------------------------------- From gwhitney at UTK.EDU Thu Apr 12 18:03:45 2001 From: gwhitney at UTK.EDU (Gretchen Whitney) Date: Thu, 12 Apr 2001 18:03:45 -0400 Subject: ABS: Bar-Ilan, Data collection methods on the Web for informetric purposes - A review and analysis Message-ID: Author's email address: judit at cc.huji.ac.il TITLE Data collection methods on the Web for informetric purposes - A review and analysis AUTHOR Bar-Ilan J JOURNAL SCIENTOMETRICS 50 (1): 7-32 JAN 2001 Document type: Review Language: English Cited References: 73 Times Cited: 0 Abstract: We present different methods of data collection fi om the Web for informetric purposes. For each method, some studies utilizing it are reviewed, and advantages and shortcomings of each technique are discussed. The paper emphasizes that data collection must be carried out with great care. Since the Web changes constantly, the findings of any study are valid only in the time frame in which it was carried out, and are dependent on the quality of the data collection tools, which are usually not under the control of the researcher. At the current time, the quality and the reliability of most of the available search tools are not satisfactory, thus informetric analyses of the Web mainly serve as demonstrations of the applicability of informetric methods to this medium, and not as a means for obtaining definite conclusions. A possible solution is for the scientific world to develop its own search and data collection tools.

A quality control procedure (article in Spanish, English abstract) Message-ID: TITLE: Bibliographic reference errors in NEFROLOGIA 1981-95. A quality control procedure (Article, Spanish) AUTHOR: Garcia, AP SOURCE: NEFROLOGIA 20 (SUPPL). 2000. p.23-28 SOC ESPANOLA NEFROLOGIA DR RAFAEL MATESANZ, MADRID Document type: Article Language: Spanish Cited References: 14 Times Cited: 0 ABSTRACT: The accuracy of the reference list is considered an essential factor in determining the quality of a scientific publication, and has been reviewed and published in several medical journals. The rate of citation errors in NEFROLOGIA has not been published before. The aim of this study has been to examine the accuracy of the references citation in the numbers of the journal published for a period of 15 years, from the first issue in 1981 to the last one on 1995. Material and methods: In this period 68 ordinary issues of the journal were published, with 520 original articles that constituted the data base, 87 articles were selected applying a fable of random numbers with 5 references of each article selected to be reviewed with a total of 435. The accuracy of the name of the authors, title of the article, volume, initial and last page and year of publication were evaluated, accordingly with the NEFROLOGIA normative. Citation errors were considered major or minor depending on whether they prevented or not the immediate retrieval of the article listed. Results: Of the 435 citations examined, 433 could be located, being impossible in 2 with the data supplied. In 189 (43,45%) 237 errors were detected, with 13,50% of them being considered major and 86,50% minor, with the greatest percentage of errors occurring in the data about the authors of the articles referenced 96 (40,50%). Conclusions: The issues of NEFROLOGIA published in this period present a high number of bibliographic reference errors, being the rate similar to other evaluated scientific periodical journals. This fact should be improved, and authors and reviewers should thoroughly check their references in order. to avoid these mistakes, as they affect the quality standard of the publication.

This factor can be of interest to authors, journal editors, and policy makers, but they should keep in mind the complexity of the determinants of impact factors while using them in coming to their particular kinds of decisions. A clearer picture of the influence a journal may have in its own scientific field rather than among all scientific journals could come from a variant of the impact factor, "the scope-adjusted impact factor". The calculation of this variant impact factor is described. A table presents some sample data horn this calculation and shows how the relative positions of some major journals shift when they are ranked by this factor rather than the unadjusted impact factor.

Benn: crb at ing.iaces TITLE Scientific impact of large telescopes AUTHOR Benn CR, Sanchez SF JOURNAL PUBLICATIONS OF THE ASTRONOMICAL SOCIETY OF THE PACIFIC 113 (781): 385-396 MAR 2001 Document type: Article Language: English Cited References: 31 Times Cited: 0 Abstract: The scientific impacts of telescopes worldwide have been compared on the basis of their contributions to (a) the 1000 most-cited astronomy papers published 1991-1998 (125 from each year) and (b) the 452 astronomy papers published in Nature during 1989-1998. Ground-based telescopes of the 1 and 2 m class account for approximate to5% of the citations to the top-cited papers; 4 m telescopes, 10%; Keck I/II, 4%; submillimeter and radio telescopes, 4%; HST, 8%; and other space telescopes, 23%. The remaining citations are mainly to theoretical and review papers. The strong showing by 1 and 2 m telescopes in the 1990s augurs well for the continued scientific impact of 4 m telescopes in the era of 8 m telescopes. The impact of individual ground-based optical telescopes is proportional to collecting area (and approximately proportional to capital cost). The impacts of the various 4 m telescopes are similar, with the CFHT leading in citation counts and WHT in Nature papers. HST has about 15 times the citation impact of a 4 m ground-based telescope but costs more than 100 times as much. Citation counts are proportional to counts of papers published in Nature, but for radio telescopes the ratio is a factor of similar to3 smaller than for optical telescopes, highlighting the danger of using either metric alone to compare the impacts of different types of telescope. Breakdowns of citation counts by subject (52% extragalactic) and journal (ApJ 44%, Nature 11%, MNRAS 9%, A&A 6%) are also presented.

Science Citation Index has since established itself as the gold standard for scientific information retrieval. It has also become the database of choice for citation analysts and evaluative bibliometricians worldwide. As scientific publication moves to the web, and novel approaches to scholarly communication and peer review establish themselves, new methods of citation and link analysis will emerge to capture often liminal expressions of peer esteem, influence and approbation. The web thus affords bibliometricians rich opportunities to apply and adapt their techniques to new contexts and content: the age of 'bibliometric spectroscopy' [2] is dawning.
