   Nyckelord :mild cognitive impairment; sibjective cognitive impairment; natural language processing; support vector machine; neural networks;

   Sammanfattning : Introduction Mild Cognitive Impairment (MCI) is a neurological condition characterized by cognitive decline greater than expected for an individual's age and education level. Subjective Cognitive Impairment (SCI) is a selfreported decline in cognitive abilities but not clinically identified as MCI. LÄS MER

3. 12. CLASSIFYING TWITTER BOTSA comparasion of methods for classifying whethert weets are written by humans or bots

   Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :Simon Västerbo; [2020]
   Nyckelord :;

   Sammanfattning : The use of bots to inuence public debate, spread disinformation and spam, creates a need for efficient methods for detecting the usage of bots. This study will compare different machine learning methods in the task of classifying if the author of a tweet is a bot or a human, using tweet level features. LÄS MER
