description: The subject of the graduate qualification work is âNamed entity recognition in textâ. Named entity recognition is one of the main natural language processing tasks with wide range of possible application in various fields. The essence of the task is extracting from text of special kind of information - named entities. Different artificial intelligence methods of dealing with this problem were reviewed during the work. Neural network based on LSTM and CRF was defined as an optimal approach for the task. Different model variations were considered during the implementation process. Implemented neural networks were tested on the same dataset and compared with each other. BiLSTM-CRF neural network showed best results on different main classification metrics, such as precision, recall and f1-score, and they were comparable with existing solutions.
