    arxiv:0707.4577 Vliyanie samocitirovaniya na Eggovskii indeks g (The influence of self-citation corrections on Egghe's g index)
    Authors: Michael Schreiber
    Comments: 9 pages, 2 figures, submitted to Scientometrics

    Posle znamenitoi stat'i Hirsha, v kotoroi byl vveden h-indeks, poyavilos' mnozhestvo popytok modificirovat' etot pokazatel' ili vvesti svoi. Napomnyu, chto h-indeks pokazyvaet chislo statei s citiruemost'yu bol'she h (t.e. indeks, ravnyi 12, pokazyvaet, chto u uchenogo est' 12 statei s citiruemost'yu vyshe 12). Indeks Hirsha ochevidno niveliruet nalichie u uchenogo neskol'kih supercitiruemyh statei (k primeru, esli vy napisali superrabotu s citiruemost'yu 10000, a potom delali srednie dobrotnye raboty, kazhdaya iz kotoryh poluchala citiruemost' 10, to do indeksa Hirsha 12 vy nikgoda ne doberetes', hotya za superrabotu vam mozhet uzhe nobelevku vruchili). Sobstvenno, indeks Hirsha dlya etogo i ne prednaznachen. On pokazyvaet produktivnost'. Mozhno ispol'zovat' ego vmeste s tradicionnym polnym citirovaniem, i togda vse budet neploho (vazhno tol'ko kak-to uchityvat' dinamiku nabora indeksov). Tem ne menee, Egg (Egghe) predlozhil svoi indeks - g - kotoryi pytaetsya odnim chislom opisat' i h-index, i vklad nebol'shogo chisla superstatei. Etot indeks pokazyvaet chislo statei, kotorye pozvolyayut nabrat' citiruemost' g2. Esli est' uchenyi, u kotorogo est' odna stat'ya s citiruemost'yu 10000, i 99 statei s nulevoi, ego indeks g budet raven 100, t.e. budet ochen' vysokim. Ego takzhe mozhno nabrat', naprimer, imeya 100 statei, kazhdaya iz kotoryh imeet citiruemost' 100. Esli raspredelenie statei po citiruemosti dostatochno gladkoe, to dva indeksa (h i g) budut dostatochno blizki drug k drugu (skazhem, po dannym NASA ADS u menya h=11, g=15 pri polnoi citiruemosti chut' za 300 i samoi citiruemoi rabote s rezul'tatom 32, vse eto s uchetom samocitiruemosti).

    V dannoi stat'e avtor rassmatrivaet, kak uchet samocitirovaniya vliyaet na indeks g. Vliyanie sil'nee, chem na hirshevskii indeks (eto yasno, t.k. v sluchae h-indeksa samocitirovanie vliyaet tol'ko vblizi kriticheskogo znacheniya, a dlya g-indeksa vliyanie vazhno "vsyu dorogu", t.k. indeks integral'nyi). Avtor polagaet, chto eto pokazyvaet preimushestvo g-indeksa. Eto tak, no tol'ko posle vychisheniya samocitirovaniya. Mne kazhetsya, chto verno i utverzhdenie o tom, chto nevychishennyi h-indeks luchshe nevychishennogo g-indeksa.
