 Description

The model is a fine-tuned byT5-base Transformer model for error detection in natural language. It is tuned for sentence classification using parallel synthetic error data and real error data from the iceErrorCorpus (IceEC, http://hdl.handle.net/20.500.12537/73) and the three specialised error corpora (L2: http://hdl.handle.net/20.500.12537/131, dyslexia: http://hdl.handle.net/20.500.12537/132, child language: http://hdl.handle.net/20.500.12537/133). The synthetic error data (35M lines of parallel data) was created by filtering and then scrambling the Icelandic Gigaword Corpus (IGC, http://hdl.handle.net/20.500.12537/192) to simulate real grammatical and typographical errors. The pretrained byT5 model was trained on the synthetic data and finally fine-tuned on the real error data from IceEC. The objective was to train a grammatical error detection model that could classify whether a sentence contains an error or not. The overall F1 score is 72.8% (precision: 76.3, recall: 71.7). --- Líkanið er byT5-base Transformer-líkan þjálfað til setningaflokkunar á samhliða gervivillugögnum og raunverulegum villum úr íslensku villumálheildinni (http://hdl.handle.net/20.500.12537/73) og sérhæfðu villumálheildunum þremur (íslenska sem erlent mál: http://hdl.handle.net/20.500.12537/131, lesblinda: http://hdl.handle.net/20.500.12537/132, barnatextar: http://hdl.handle.net/20.500.12537/133). Gervivillugögnin (35 milljón línur af samhliða gögnum) voru búin til með því að sía og svo rugla íslensku Risamálheildinni (http://hdl.handle.net/20.500.12537/192) með því að nota margs konar villumynstur til að líkja eftir raunverulegum málfræði- og ritunarvillum. Forþjálfaða byT5-líkanið var þjálfað á gervivillugögnunum og svo fínþjálfað á raungögnum úr villumálheildunum. Tilgangurinn var að þjálfa líkan sem gæti sagt til um hvort líklegt væri að setning innihéldi villu eða ekki. F1 fyrir líkanið er 72,8% (nákvæmni: 76,3, heimt: 71,7).
