Kompozit indeks (metrika)

Kompozit indeks yoki kompozit koʻrsatkich (qisqacha: c-score deb yuritiladi))[1][2] — olim qaysi ilm-fan sohasida faoliyat koʻrsatishidan qatʼi nazar, uning ilmiy nashrlari sifatini baholaydigan raqamli koʻrsatkich[3][4][5].

Ushbu koʻrsatkich dastlab 2016-yilda Stenford universiteti qoshidagi grek-amerikan metailm tadqiqotchisi John Ioannidis tomonidan taklif etilgan[6]. 2019-yilda unga yanada takomillashtirilgan oʻzgartirishlar kiritildi[7].

C-score barcha ilmiy tadqiqot sohalarini birlashtiruvchi hamda Scopus maʼlumotlar bazasidagi barcha yoʻnalishlar, hattoki iqtibos keltirish salmogʻi past boʻlgan sohalar boʻyicha ham tadqiqotlarni darajalarga ajratuvchi algoritm yordamida hisoblanadi[8]. Bu usul tadqiqotchilarga har bir ilmiy yoʻnalishni yagona tizim asosida qamrab olgan holda, dunyodagi eng nufuzli olimlarning kuchli 2 foizlik (TOP-2%) roʻyxatini aniqlash imkonini berdi[9][10].

Tadqiqotchining c-score koʻrsatkichini belgilovchi parametrlar quyidagilardir:

  • olingan iqtiboslarning umumiy soni;
  • olingan iqtiboslar uchun Xirsh indeksi;
  • olingan iqtiboslar uchun Shrayber hammualliflik hisobga olingan tuzatilgan Hm indeksi;
  • olim yagona muallif boʻlgan maqolalarga berilgan iqtiboslarning umumiy soni;
  • olim yagona yoki birinchi muallif boʻlgan maqolalarga berilgan iqtiboslarning umumiy soni;
  • olim yagona, birinchi yoki oxirgi muallif boʻlgan maqolalarga berilgan iqtiboslarning umumiy soni.
