abstract = {We address the automatic extraction from publications of two key concepts for representing research processes: the concept of research activity and the sequence relation between successive activities. These representations are driven by the Scholarly Ontology, specifically conceived for documenting research processes. Unlike usual named entity recognition and relation extrac- tion tasks, we are facing textual descriptions of activities of widely variable length, while pairs of successive activities often span multiple sentences. We developed and experimented with several sliding window classifiers using Logistic Regression, SVMs, and Random Forests, as well as a two-stage pipeline classifier. Our classifiers employ task-specific features, as well as word, part-of-speech and dependency embeddings, engineered to exploit distinctive traits of research publications written in English. The extracted activities and sequences are associated with other relevant information from publication metadata and stored as RDF triples in a knowledge base. Evaluation on datasets from three disciplines, Digital Humanities, Bioinformatics, and Medicine, shows very promising performance.},

abstract = {Extraction of information from a research article, association with other sources and inference of new knowledge is a challenging task that has not yet been entirely addressed. We present Research Spotlight, a system that leverages existing information from DBpedia, retrieves articles from repositories, extracts and interrelates various kinds of named and non-named entities by exploiting article metadata, the structure of text as well as syntactic, lexical and semantic constraints, and populates a knowledge base in the form of RDF triples. An ontology designed to represent scholarly practices is driving the whole process. The system is evaluated through two experiments that measure the overall accuracy in terms of token- and entity- based precision, recall and F1 scores, as well as entity boundary detection, with promising results.},

abstract = {Archaeology and material cultural heritage enjoys a particular status as a form of heritage that, capturing the public imagination, has become the locus for the expression and negotiation of regional, national, and intra-national cultural identities. One important question is: why and how do contemporary people engage with archaeological heritage objects, artefacts, information or knowledge outside the realm of an professional, academically-based archaeology? This question is investigated here from the perspective of theoretical considerations based on Yuri Lotman’s semiosphere theory, which helps to describe the connections between the centre and peripheries of professional archaeology as sign structures. The centre may be defined according to prevalent scientific paradigms, while periphery in the space of creolisation in which, through interactions with other culturally more distant sign structures, archaeology-related nonprofessional communities emerge. On the basis of these considerations, we use collocation analysis on representative English language corpora to outline the structure of the field of archaeology-related nonprofessional communities, identify salient creolised peripheral spaces and archaeology-related practices, and develop a framework for further investigation of archaeological knowledge production and reuse in the context of global archaeology.},
