چکیده

Grammar errors and context-sensitive spelling errors in texts written by second language learners are hard to detect automatically. We have used three different approaches for grammar checking: manually constructed error detection rules, statistical differences between correct and incorrect texts, and machine learning of specific error types. The three approaches have been evaluated using a corpus of second language learner Swedish. We found that the three methods detect different errors and therefore complement each other. Svensk sammanfattning Grammatikfel och kontextberoende stavfel (felstavningar som bildar riktiga ord) i texter skrivna av andraspråksinlärare är svårt att detektera automatiskt. Vi har använt tre olika angreppssätt för granskningen: manuellt konstruerade feldetekteringsregler, statistiska skillnader mellan korrekt och felaktig text, samt maskininlärning av specifika feltyper. De tre metoderna har vi utvärderat på en korpus bestående av svenska uppsatser av andraspråksinlärare. Vi fann att metoderna upptäcker olika fel och därför kompletterar varandra väl.
