Abstract
Cilj ovog diplomskog rada je razvoj modela visoke točnosti za prepoznavanje imenovanih entiteta adresa. Izazovi uključuju raznolikost, dvosmislenost i kompleksnost entiteta adrese. Različite arhitekture modela korištene za treniranje klasifikatora su jednostavniji modeli logističke regresije i algoritam slučajnih šuma te složeniji model temeljen na dvosmjernoj povratnoj neuronskoj mreži s dodatnim slojem koji sadrži uvjetovana slučajna polja (BiLSTM-CRF) i implementiran je pomoću Flair knjižnice. Sva testiranja provedena su na dva skupa podataka koji se razlikuju po načinu označavanja temeljenom na granularnosti imenavanog entiteta: adresa kao cjelina i adresa sastavljena od podelemenata. Za oba skupa podataka najbolje rezultate postiže model temeljen na BiLSTM-CRF arhitekturi s jednim RNN slojem te treniran ili samo na BERT-u ili na kombinaciji BERT i GloVe embedding-a.
Abstract (english)
This thesis focuses on developing a high-performing named entity recognition model for addresses. Challenges including diversity, ambiguity and complexity of the address entity are introduced as well as the different model architectures used for training the classifier. These include the simpler logistic regression and random forest models as well as the more complex bidirectional LSTM network with a conditional random field layer (BiLSTM-CRF) implemented using Flair framework. Experiments are conducted using variously configured models on two sets of corpora tagged differently based on address entity granularity: entire address and address consisting of subparts. For both corpora, the best results are achieved on a BiLSTM-CRF architecture model with a single RNN layer trained on either standalone BERT embeddings or a stacked combination of BERT and GloVe.
