Holidog, a marketplace that provides services related to pets, needs to solve this challenge using an autonomous approach. In these pages, you will find the analysis and solution designed for them: A filter based on the content of the messages to filter away the ones that go against the terms and conditions of the platform, with good enough results for production use.51 p.application/pdfspamemòria: cc-by-sa (c) Eudald Arranz Tresserra, 2019http://creativecommons.org/licenses/by-sa/3.0/es/Sistemes classificadors (Intel·ligència artificial)Tractament del llenguatge natural (Informàtica)ProgramariTreballs de fi de grauXarxes socials en líniaXats (Internet)Learning classifier systemsNatural language processing (Computer science)Computer softwareOnline social networksOnline chat grupsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
