Compania IBM a lansat ini\u021biativa CodeNet, care vizeaz\u0103 furnizarea cercet\u0103torilor a unui set de date pentru a experimenta utilizarea metodelor de \u00eenv\u0103\u021bare automat\u0103 \u00een crearea translatorilor \u00eentre diferite limbaje de programare, precum \u0219i generatoare \u0219i analizatori de cod. CodeNet include o colec\u021bie de 14 milioane de exemple de cod care rezolv\u0103 4053 de probleme tipice de programare. \u00cen total, colec\u021bia con\u021bine aproximativ 500 de milioane de linii de cod \u0219i acoper\u0103 55 de limbaje de programare, inclusiv limbaje moderne precum C++, Java, Python \u0219i Go, dar \u0219i limbaje \u00eenvechite, precum COBOL, Pascal \u0219i FORTRAN. Lucr\u0103rile proiectului sunt distribuite sub licen\u021ba Apache 2.0, iar seturile de date urmeaz\u0103 s\u0103 fie distribuite ca domeniu public. <\/p>\n
Exemplele sunt \u00eenso\u021bite de anota\u021bii \u0219i implementeaz\u0103 algoritmi identici \u00een diferite limbaje de programare. Se presupune c\u0103 setul propus va ajuta la instruirea sistemelor de \u00eenv\u0103\u021bare automat\u0103 \u0219i la dezvoltarea inova\u021biilor \u00een domeniul traducerii \u0219i analizei automate a codului, similar cu modul \u00een care baza de date cu imagini annotate ImageNet a sprijinit dezvoltarea sistemelor de recunoa\u0219tere a imaginilor \u0219i a viziunii artificiale. Ca una dintre sursele cheie ale form\u0103rii colec\u021biei sunt men\u021bionate diverse competi\u021bii de programare. <\/p>\n
Spre deosebire de translatorii tradi\u021bionali, implementa\u021bi pe baza regulilor de transformare, sistemele de \u00eenv\u0103\u021bare automat\u0103 pot captura \u0219i lua \u00een considerare contextul utiliz\u0103rii codului. Atunci c\u00e2nd se transform\u0103 un limbaj de programare \u00een altul, contextul este la fel de important ca \u0219i atunci c\u00e2nd se traduce dintr-o limb\u0103 uman\u0103 \u00een alta. Tocmai absen\u021ba lu\u0103rii \u00een considerare a contextului \u00eempiedic\u0103 transformarea codului din limbaje vechi, cum ar fi COBOL. <\/p>\n
Disponibilitatea unei baze mari de implement\u0103ri de algoritmi \u00een diverse limbaje va sprijini crearea de sisteme universale de \u00eenv\u0103\u021bare automat\u0103, care, \u00een loc de o traducere direct\u0103 \u00eentre limbajele specifice, manipuleaz\u0103 o reprezentare mai abstract\u0103 a codului, independent\u0103 de limbajele de programare specifice. Un asemenea sistem ar putea fi folosit ca translator, translat\u00e2nd codul furnizat \u00eentr-o reprezentare intern\u0103 abstract\u0103, din care ar putea fi generat apoi cod \u00een multiple limbaje. <\/p>\n
Sistemul va putea, de asemenea, s\u0103 efectueze conversii bidirec\u021bionale. De exemplu, \u00een b\u0103nci \u0219i institu\u021bii guvernamentale continu\u0103 s\u0103 fie utilizate proiecte scrise \u00een limbajul \u00eenvechit COBOL. Un traduc\u0103tor bazat pe un sistem de \u00eenv\u0103\u021bare automat\u0103 va putea transforma codul \u00een COBOL \u00eentr-o reprezentare \u00een Java, iar, dac\u0103 este necesar, s\u0103 converteasc\u0103 un fragment din Java \u00eenapoi \u00een codul COBOL. <\/p>\n
Pe l\u00e2ng\u0103 traducerea \u00eentre limbaje, domeniile de aplicare men\u021bionate pentru CodeNet includ crearea de sisteme inteligente de c\u0103utare a codului \u0219i automatizarea identific\u0103rii clonelor, precum \u0219i dezvoltarea de optimizatoare \u0219i sisteme de corectare automat\u0103 a codului. \u00cen special, exemplele prezentate \u00een CodeNet sunt \u00eenso\u021bite de metadate care descriu rezultatele test\u0103rii performan\u021bei, dimensiunea programului rezultat, consumul de memorie \u0219i starea care permite diferen\u021bierea codului corect de cel cu erori (pentru a distinge codul corect de cel incorect, \u00een colec\u021bie sunt incluse \u00een mod special exemple cu erori, ponderea lor fiind de 29,5%). Sistemul de \u00eenv\u0103\u021bare automat\u0103 poate \u021bine cont de aceste metadate pentru a genera cel mai optim cod sau pentru a identifica regresiile \u00een codul analizat (sistemul poate \u00een\u021belege c\u0103 algoritmul implementat \u00een codul transmis nu este optim sau con\u021bine erori). \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f IBM \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u0438\u043b\u0430 \u0438\u043d\u0438\u0446\u0438\u0430\u0442\u0438\u0432\u0443 CodeNet, \u043d\u0430\u0446\u0435\u043b\u0435\u043d\u043d\u0443\u044e \u043d\u0430 \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u0435\u043d\u0438\u0435 \u0438\u0441\u0441\u043b\u0435\u0434\u043e\u0432\u0430\u0442\u0435\u043b\u044f\u043c \u043d\u0430\u0431\u043e\u0440\u0430 \u0434\u0430\u043d\u043d\u044b\u0445, \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0438\u0445 \u044d\u043a\u0441\u043f\u0435\u0440\u0438\u043c\u0435\u043d\u0442\u0438\u0440\u043e\u0432\u0430\u0442\u044c \u0441 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u0435\u043c \u043c\u0435\u0442\u043e\u0434\u043e\u0432 \u043c\u0430\u0448\u0438\u043d\u043d\u043e\u0433\u043e \u043e\u0431\u0443\u0447\u0435\u043d\u0438\u044f \u0434\u043b\u044f \u0441\u043e\u0437\u0434\u0430\u043d\u0438\u044f \u0442\u0440\u0430\u043d\u0441\u043b\u044f\u0442\u043e\u0440\u043e\u0432 \u0438\u0437 \u043e\u0434\u043d\u043e\u0433\u043e \u044f\u0437\u044b\u043a\u0430 \u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u0432 \u0434\u0440\u0443\u0433\u043e\u0439, \u0430 \u0442\u0430\u043a\u0436\u0435 \u0433\u0435\u043d\u0435\u0440\u0430\u0442\u043e\u0440\u043e\u0432 \u0438 \u0430\u043d\u0430\u043b\u0438\u0437\u0430\u0442\u043e\u0440\u043e\u0432 \u043a\u043e\u0434\u0430.
