  1. 21. Text feature mining using pre-trained word embeddings

    University essay from KTH/Matematisk statistik

    Author : Henrik Sjökvist; [2018]
    Keywords : Word embeddings; Feature engineering; Unsupervised learning; Deep learning; fast Text; Operational risk; Ordvektorer; Attributgenerering; Oövervakat lärande; Djupinlärning; fastText; Operativ risk;

    Abstract : This thesis explores a machine learning task where the data contains not only numerical features but also free-text features. In order to employ a supervised classifier and make predictions, the free-text features must be converted into numerical features.  In this thesis, an algorithm is developed to perform that conversion.

  3. 22. Semantic Text Matching Using Convolutional Neural Networks

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Run Fen Wang; [2018]
    Keywords : Text matching; CNN; TF-IDF; Word embedding; Word2vec; NLP;

    Abstract : Semantic text matching is a fundamental task for many applications in NaturalLanguage Processing (NLP). Traditional methods using term frequencyinversedocument frequency (TF-IDF) to match exact words in documentshave one strong drawback which is TF-IDF is unable to capture semanticrelations between closely-related words which will lead to a disappointingmatching result.

  5. 24. Topic discovery and document similarity via pre-trained word embeddings

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simin Chen; [2018]
    Keywords : Document similarity; document representation; word embedding; natural language processing; topic modeling; ;

    Abstract : Throughout the history, humans continue to generate an ever-growing volume of documents about a wide range of topics. We now rely on computer programs to automatically process these vast collections of documents in various applications. Many applications require a quantitative measure of the document similarity.

  6. 25. Natural Language Processing in Artificial Neural Networks: Sentence analysis in medical papers

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Konstantin-Klemens Lurz; [2018]
    Keywords : Machine Learning; Natural Language Processing; Medical Papers; Convolutional Neural Networks; Word2Vec; Physics and Astronomy;

    Abstract : Convolutional Neural Networks (CNNs) and pre-trained word embeddings have revolutionized the field of Natural Language Processing (NLP) during the last years. In this project, CNNs are used on top of the Word2Vec word representation for a sentence classification task on medical research articles. READ MORE
