We present QAnswer, a Question Answering system which queries at the same time 3 core datasets of the Semantic Web, that are relevant for end-users. These datasets are Wikidata with Lexemes, LinkedGeodata and Musicbrainz. Additionally, it is possible to query these datasets in English, German, French, Italian, Spanish, Pourtuguese, Arabic and Chinese. Moreover, QAnswer includes a fallback option to the search engine Qwant when the answer to a question cannot be found in the datasets mentioned above. These features make QAnswer as the first prototype of a Question Answering System over a considerable part of the LOD cloud.

Abstract. The PET-BCC group is a thematic group focused on software development. Unlike conventional PET groups, thematic PETs also have the responsibility of developing activities concerning its theme, bringing expertise and contributing in a more reliable way to the students' academic formation. In this paper, we introduce projects under development, with special emphasis on the Sessional Tutoring Program (from Brazilian Portuguese: "Programa de Acompanhamento"), describing its particularities and outcomes. In addition, we discuss the group's working dynamics and organization, as well as we show the challenges, constraints, and management strategies that are currently adopted so other groups may benefit from them.Resumo. O PET-BCCé um grupo temático com o foco em desenvolvimento de software. Diferentemente de grupos PET convencionais, os temáticos possuem a responsabilidade de desenvolver atividades também voltadas ao seu tema, gerando expertise e contribuindo de forma mais pontual para a formação dos estudantes. Neste artigo apresentamos os projetos desenvolvidos, dando maiorênfase, no entanto, no projeto nomeado Programa de Acompanhamento, descrevendo suas particularidades e resultados. Discorremos também sobre a organização e a dinâmica de funcionamento do grupo além de apresentar os desafios, limitações, e estratégias de gerenciamento que são atualmente adotadas de forma que outros grupos PET possam se beneficiar. 80
