Thisvolumecontainsoneinvitedand?fteensubmittedpaperspresentedatthe Tenth International Conference on Inductive Logic Programming (ILP2000). The?fteenacceptedpaperswereselectedbytheprogramcommitteefromthe 37paperssubmittedtotheconference. Eachpaperwascarefullyreviewedby threereferees. ILP2000washeldatImperialCollege,London,24-27July2000andwasin- grated with the First International Conference on Computational Logic (CL2000). With ILP's strong roots in computational logic, this was a na- ralmarriage. CL2000wasa?ve-dayextravaganza,incorporatingboththeSixth InternationalConferenceonRulesandObjectsinDatabases(DOOD2000)and theTenthInternationalWorkshoponLogic-basedProgramSynthesisandTra- formation(LOPSTR2000)andfeaturingeightinvitedspeakers,twelvetutorials, andsevena?liatedworkshops.
