Atlante Dialettale in rete: ALT-Web

The paper presents an on-line dialectal resource, ALT-Web, which gives access to the linguistic data of the Lexical Atlas of Tuscany or Atlante Lessicale Toscano, a specially designed linguistic atlas in which lexical data have both a diatopic and diastratic characterisation. The paper illustrates ALT-Web with particular emphasis on: 1) the dialectal data representation model; 2) the access modalities to the ALT dialectal corpus designed to produce an output tailored to the specific needs of the different classes of users (both professionals and common citizens); 3) ontology-based search. These represent three main features which differentiate ALT-Web both from the previous digitalised ALT version and, most interestingly, from other on-line dialectal resources. At the time of writing, this is the first resource of this type in Italy, and one of the few at the international level.
