U okviru predlo\u017eenog formalizma definirat \u0107emo skup pristupa koji omogu\u0107avaju kvantitativnu i kvalitativnu analizu tekstualnih podataka prikupljenih iz dru\u0161tvenih medija. Cilj takve analize je da se identificiraju zna\u010dajke prema kojima mo\u017eemo razlikovati razli\u010dite obrasce \u0161irenja informacija. To je prvi korak prema definiciji algoritama za automatsku klasifikaciju informacija.[\/vc_column_text][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][vc_row height_ratio=”50″ padding_top_multiplier=”2x” rc_bg_type=”image” rc_bg_image=”6292″ rc_bg_image_type=”horizontal-parallax-rl” rc_bg_image_size=”full” rc_bg_parallax_threshold=”0.5″][vc_column vertical_content_position=”bottom” text_align=”center”][vc_row_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][\/vc_row_inner]

U istra\u017eivanju \u0107emo primijeniti skup metoda i tehnika koje se zasnivaju na neuronskim mre\u017eama i dubokom u\u010denju (R. Collobert et al., 2011; Q. Le & t. Mikolov, 2013; LeCun, Bengio & Hinton, 2015). Tako\u0111er, koristit \u0107emo i neke klasi\u010dne pristupe iz podru\u010dja ra\u010dunalne analize prirodnog jezika (C. Manning & H. Sch\u00fctze, 1999). Primijenit \u0107emo postupke izlu\u010divanja klju\u010dnih rije\u010di, klasifikacije tekstova, analize sentimenta, idr.<\/p>\n

Analiza na razini konteksta (context-based analysis) podrazumijeva analizu \u0161irenja informacija na dru\u0161tvenim mre\u017eama uzimaju\u0107i u obzir globalnu sredi\u0161nju i lokalnu razinu mre\u017ee (A. R\u00e9ka & A. Barab\u00e1si, 2002; S. Boccaletti et al., 2006). Dodatno, analiza obuhva\u0107a razli\u010dite slojeve \u0161irenja poruke s ciljem objedinjavanja razli\u010ditih aspekata \u0161irenja poruke (npr. tweet, retweet, quote, mention) na razli\u010ditim platformama. Tako je mogu\u0107e u analizu uklju\u010diti veze unutar jednog sloja (inter-layer connections) i veze izme\u0111u slojeva (intra-layer connections).<\/p>\n

Analiza na razini dinamike (dynamic-based analysis) bavit \u0107e se kaskadnom dinamikom mre\u017ee \u0161irenja poruka (J. Mahdi & M. Perc, 2017; D. Brien et al., 2019). Analiza dinamike zapravo obuhva\u0107a temporalni aspekt odvijana korisni\u010dkih aktivnosti oko \u0161irenja poruke kao \u0161to su dijeljenje sadr\u017eaja, komentiranje sadr\u017eaja, \u201elajkanje\u201c sadr\u017eaja.[\/vc_column_text][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
