HONto: A Bottom-Up Knowledge Base from Textbooks for Recommending Contextually Relevant Documents

Abstract Discarding is considered by many as an important problem in world fisheries. In many regions, data collection onboard commercial vessels has intensified, and the understanding of both human and ecological drivers of discards is improving quickly. Discarding patterns vary widely across regions, fisheries, gears, and species. Fishers' responses to regulations and markets explain these complex patterns, on top of resource availability partly driven by environmental fluctuations. This expanded knowledge base provides an appropriate basis for discussing the discard mitigation measures proposed in various settings. In September 2012, a theme session was convened at the ICES Annual Science Conference in Bergen, Norway, to discuss these issues. This themed set of articles includes several of the studies presented at the theme session. Owing to the wide diversity of drivers and reasons for discarding, no single management measure or even framework is expected to address the issue. Rather, discard mitigation measures need to be tailored to each particular fishery, or even species within a fishery, and the effectiveness of solutions is greatest when they are used in combination with other approaches. Bottom-up approaches to bycatch and discard management, which involve incentive-based solutions to bycatch problems, were agreed to be the most promising.

The present study describes the preliminary findings of a research project aiming at creating a knowledge-base for the protection of caves heritage at Rio Vermelho preservation area in the central Brazilian highlands. A GIS-based relief compartment mapping was conducted using readily available data (e.g., satellite images, geological, and cave location maps). Four resultant geomorphological domains were identified, including (i) lowlands (282 km2) with a baselevel in silicates and carbonates, (ii) the karst terrains (994 km2) which were developed in carbonates trapped by siltstone lenses, (iii) the talus (1483 km2) having colluvial and alluvial units deposited by the escarpment retreat (Urucuia Formation) and (iv) the highlands (1143.7 km2) developed over the sandstone of the Urucuia Group. The intersection of landform and geological maps resulted in delineating two abrupt contacts, the first between lowland and karst terrains and the second between the talus and highlands that formed canyon escarpment. For sustainability perspective, this study proposed two types of cave systems in the region as superior/vadose (top-bottom) that collect floods from hillslopes and deep Epigene fluvial-karst (bottom-up).

Text Version

This paper presents a exible bottom-up process to incrementally generate several versions of the same text, building up the core text from its kernel version into other versions varying of the levels of details. We devise a method for identifying the question/answer relations holding between the propositions of a text, we give rules for characterizing the kernel version of a text, and we provide a procedure, based on causal and temporal expansions of sentences, which distinguishes semantically these levels of details according to their importance. This is based on the assumption that we have a stock of information from the interpreter's knowledge base available. The sentence expansion operation is formally defined according to three principles: (1) the kernel principle ensures to obtain the gist information; (2) the expansion principle defines an incremental augmentation of a text; and (3) the subsume principle defines an importance-based order among the possible details of the information. The system developed allows users to generate in a follow-up way their own text version which meets their expectations and their demands expressed as questions about the text under consideration.

PurposeThe purpose of this paper is to explore the provision and reported outcomes of Experiential Entrepreneurship Education (EEE), from learner, educator and university perspectives, in order to reflect upon the progress of the Entrepreneurial University. It proposes a conceptual framework for integrating the multiple stakeholder perspectives for an “education led” and student-focused Entrepreneurial University, something yet to be identified from existing research and, consequentially, future research.Design/methodology/approachA reflective literature review explores the depth and breadth of EEE provision in Universities, noting: what is taking place, who is involved, where EEE is situated (within the university context), and how the knowledge base is informed. From these reflections, a conceptual framework is proposed as a means of exploring and categorizing progress towards a student-focused Entrepreneurial University through education experiences.FindingsThe literature review is largely informed by case studies developed by educators reflecting on student learner experiences for the purpose of course enhancement. These case exemplars provide the resource for emergent, bottom-up strategy that could support the Entrepreneurial University. However, the role of the University is less researched, in terms of providing context and external strategic relationships to resource EEE and deliver a more planned approach to the Entrepreneurial University. The Entrepreneurial University and EEE are mainstream agendas and the development of both must consider the role and contribution of the University in terms of strategy formulation and implementation.Originality/valueThis study takes a holistic view, seeing EEE and the Entrepreneurial University as connected agendas. The student-focused Entrepreneurial University cannot result from emergent, bottom-up strategy alone and thus there is a need to address the role of top-down resource-based University strategy in creating real progress. The paper provides a conceptualization, for the purpose of analysing and informing the relationship between EEE and the Entrepreneurial University that places the University as a key stakeholder, and in doing so asks that scholars and educators build the knowledge base not only from cases of good practice but also from the review of strategic management within Universities.
