We extend this concept to language families which results in families [Formula: see text]. For [Formula: see text] and [Formula: see text] be the families of finite, regular, context-free, context-sensitive or recursively enumerable language, respectively, we determine the hierarchy of the families [Formula: see text] and compare these families with those of the Chomsky hierarchy. Furthermore, we present the status of decidability of the membership problem, emptiness problem and finiteness problem for the families [Formula: see text].<\/jats:p>","DOI":"10.1142\/s0129054105003212","type":"journal-article","created":{"date-parts":[[2005,7,5]],"date-time":"2005-07-05T14:52:13Z","timestamp":1120575133000},"page":"645-662","source":"Crossref","is-referenced-by-count":7,"title":["LANGUAGE FAMILIES DEFINED BY A CILIATE BIO-OPERATION: HIERARCHIES AND DECISION PROBLEMS"],"prefix":"10.1142","volume":"16","author":[{"given":"J\u00dcRGEN","family":"DASSOW","sequence":"first","affiliation":[{"name":"Otto-van-Guericke-Universi\u00e4t Magdeburg, Fakult\u00e4t f\u00fcr Informatik, PSF 4120, D\u201339016 Magdeburg, Germany"}]},{"given":"MARKUS","family":"HOLZER","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Informatik, Technische Universit\u00e4t M\u00fcnchen, Boltzmannstr. 3, D\u201385748 Garching bei M\u00fcnchen, Germany"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-45005-X_10"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3975(03)00139-7"},{"key":"rf3","first-page":"477","volume":"8","author":"Daley M.","journal-title":"J.
