Mahsulot tavsifi

Ushbu mahsulot aspekt darajasidagi sentiment tahlilini amalga oshirish uchun ikkita konvolyutsion neyron tarmog‘idan (CNN) iborat yangi modelni taklif qiladi. Birinchi CNN maqsadli aspekt uchun aspekt xaritasini (aspect map) aniqlaydi, ikkinchisi esa ushbu xarita asosida aspektdagi ijobiy yoki salbiy fikrni klassifikatsiya qiladi. Model aspekt ifodalari va ularning atrofidagi sentiment ifodalarining joylashuviga xalok bo‘lgan pozitsion axborotni o‘zlashtirishda yordam beradi, shu bilan ABSA uchun an’anaviy hisoblangan e’tibor mexanizmlarining muammolarini bartaraf etadi. Shuningdek, model noaniq (weakly supervised) o‘rganish sharoitida ham samarali ishlaydi, chunki so‘z darajasidagi annotatsiyalar bo‘lmagan holatlarda ham foydalanish imkonini beradi.
