Strong verb lemmas from a corpus of old english. Advances and issues

The aim of this article is to devise the method of lemmatisation of strong verbs from a corpus of Old English with a view to maximising the automatic search for the inflectional forms, with the corresponding minimisation of manual revision of the verbs under analysis. The search algorithm, which consists of query strings and filters, is launched on the lemmatiser Norna, a component of the lexical database of Old English Nerthus. The conclusions of the article insist on the limits of automatic lemmatisation as well as the paths of refinement of the lemmatisation method in order to accomodate less predictable forms.
