El jurat en destaca la cura "exquisida" del catàleg, la qualitat dels llibres i el "respecte" pels lectors. ACN Madrid.-L\\\\'editorial valenciana Media Vaca ha obtingut el Premi Nacional a la Millor Labor Editorial Cultural corresponent a l\\\\'any 2018 que atorga el Ministeri de Cultura i Esports. El guardó pretén distingir la tasca editorial d\\\\'una persona física o jurídica que hagi destacat per l\\\\'aportació a la vida cultural espanyola. El premi és de caràcter honorífic i no té dotació econòmica. En el cas de Media Vaca, fundada pel valencià Vicente Ferrer i la bilbaïna Begoña Lobo, el jurat n\\\\'ha destacat la cura "exquisida" del catàleg, la qualitat dels llibres i el "respecte" pels lectors i per la resta d\\\\'agents de la cadena del llibre. Media Vaca va publicar els primers llibres el desembre del 1998. El catàleg actual el componen 64 títols dividits en sis col·leccions, que barregen ficció i no ficció. Des del Ministeri de Cultura es destaca que la il·lustració té un pes "fonamental" als productes de l\\\\'editorial i que la majoria de projectes solen partir de propostes literàries i textos preexistents. L\\\\'editorial ha rebut quatre vegades el Bologna Ragazzi Award. És l\\\\'única editorial estatal que ha aconseguit el guardó que atorga la Fira del Llibre per a Nens de Bolonya, la més important del sector.',

Dataset Creation

Methodology

We crawled 219.586 articles from the Catalan News Agency (www.acn.cat) newswire archive, the latest from October 11, 2020. We used the "subsection" category as a classification label, after excluding territorial labels (see territorial_labels.txt file) and labels with less than 2000 occurrences. With this criteria compiled a total of 153.265 articles for this text classification dataset.

Curation Rationale

We used the "subsection" category as a classification label, after excluding territorial labels (see territorial_labels.txt file) and labels with less than 2000 occurrences.

Source Data

Initial Data Collection and Normalization

The source data are crawled articles from ACN (Catalan News Agency) site: www.acn.cat

Who are the source language producers?

The Catalan News Agency (CNA, in Catalan: Agència Catalana de Notícies (ACN)) is a news agency owned by the Catalan government via the public corporation Intracatalònia, SA. It is one of the first digital news agencies created in Europe and has been operating since 1999 (source: [https://en.wikipedia.org/wiki/Catalan_News_Agency])

Who are the annotators?

Editorial staff classified the articles under the different thematic sections, and we extracted these from metadata.
