The aim of this paper is to present a new tool to do dialectometry. The program, called "DiaTech", has been incorporated features of previous programs, and especially by the VDM program created under the direction of H. Goebl, researcher of the Salzburg University. The main goal of the new tool is to motivate Dialectology studies and dialectologists, putting in their hands a comfortable and efficient tool.

V prispevku so predstavljeni prvi rezultati Socio-in geolingvistič-nega atlasa baskovskega jezika -EAS. Raziskovalni projekt je bil predstavljen na 5. konferenci SIDG, ki je bila v Bragi. Predstavljamo nekatere podatke, zbrane na isti lokaciji pri informatorjih različnih generacij (starejša, srednja, mlajša). Raziskujemo jezikovne razlike, ki se pojavljajo med govorci teh generacij, in analiziramo, ali so medgeneracijske razlike enake na vseh lokacijah ali pa se med njimi pojavljajo kakšne posebnosti. Prikazujemo tudi različne tipe geolingvističnih variacij med generacijami.In this contribution, we show the first results of the "Socio-geolinguistic atlas of the Basque language-EAS". This research project was presented at the Vth Congress of Dialectology and Geolinguistics held in Braga. On the one hand, we present some data collected in the same locality from informants of different generations (the elderly, adults and young people). We examine the linguistic differences that we found among people of these generations and we analyse whether the difference among generations is similar in all localities or not, or whether some of them have peculiar characteristics. On the other hand, we show different types of geolinguistic variation: variation among elderly people, adults or among young people.Ključne besede: sociolingvistična variacija, geolingvistična variacija, jezikovni korpus, baskovska dialektologija

The lack of homogeneous data recorded by similar methodologies has been a handicap to the development of more advanced studies on the dialectal variation of Basque. Now that the first five volumes of the Linguistic Atlas of the Basque Language have been published, researchers have access to a great amount of data and the possibility to use more sophisticated procedures to analyze the variation of the Basque language from a geolinguistic point of view.In this contribution, we use data taken from the fifth volume of this atlas, which is devoted to noun morphology. First, these data will be analyzed linguistically, and instead of using the phonetic representation, we will use the phonological or underlying representation. In order to do this, we will analyze the inventory of the morphological suffixes used in nominal inflexion cases and the phonological rules which appear in these cases (mainly assimilation, dissimilation, insertion and deletion), using the classical view of generative phonology.As far as the cartography of the data is concerned, we will use the recently created

In dialectology we often encounter irreducible variation in its data, i.e., multiple responses to its probes about the form of a word or phrase. Dialectometry seeks to measure the differences between dialects and has developed several ways to measure the difference between responses when one or both of them is non-unique. We introduce here BILBAO DISTANCE, where the cardinality of response is unimportant, which may be combined with various weighting functions such as edit distance or inverse frequency weighting, and which yields intuitively appealing measures, e.g., when applied to a singleton set {a} and a set with the same element plus a second, yields d({a},{a,b}) = 0.5. It overcomes flaws in earlier proposals and is conceptually simpler and computationally more efficient to apply than earlier measures. We suspect that its results satisfy the metric axioms, as it is certainly symmetric and measures the difference between identical sets as zero.
