Deduction over Mixed-Level Logic Representations for Text Passage Retrieval

A system is described that uses a mixed-level representation of (part of) meaning of natural language documents (based on standard Horn Clause Logic) and a variable-depth search strategy that distinguishes between the different levels of abstraction in the knowledge representation to locate specific passages in the documents. Mixed-level representations as well as variable-depth search strategies are applicable in fields outside that of NLP.Comment: 8 pages, Proceedings of the Eighth International Conference on Tools with Artificial Intelligence (TAI'96), Los Alamitos C

Concrete utopianism in integrated assessment models: Discovering the philosophy of the shared socioeconomic pathways

The Shared Socioeconomic Pathways (SSPs) are at the forefront of climate change science today. As an influential methodology and method, the SSPs guide the framing of numerous climate change research questions and how these are investigated. Although the SSPs were developed by an interdisciplinary group of scientists in a well-documented process, there is no apparent consensus in the literature that answers the question, "What is the philosophy of science behind the SSPs?" To investigate, the paper applies a systematic thematic qualitative content analysis to the dataset of published papers that establish the rules and expectations for using the SSPs. The research determines that there is no obvious and concise statement on the epistemological and ontological foundation of the SSPs. However, based on the evidence identified in the dataset, SSPs are implicitly, though not explicitly, consistent with a critical realist and concrete utopian philosophy as coined by Roy Bhaskar. This is the first paper to discuss the philosophical underpinning of the SSPs

Physical processes, their life and their history

Here, I lay the foundations of a high-level ontology of particulars whose structuring principles differ radically from the 'continuant' vs. 'occurrent' distinction traditionally adopted in applied ontology. These principles are derived from a new analysis of the ontology of “occurring” or “happening” entities. Firstly, my analysis integrates recent work on the ontology of processes, which brings them closer to objects in their mode of existence and persistence by assimilating them to continuant particulars. Secondly, my analysis distinguishes clearly between processes and events, in order to make the latter abstract objects of thought (alongside propositions). Lastly, I open my ontological inventory to properties and facts, the existence of which is commonly admitted. By giving specific roles to these primitives, the framework allows one to account for static and dynamic aspects of the physical world and for the way that subjects conceive its history: facts account for the life of substances (physical objects and processes), whereas events enable cognitive subjects to account for the life story of substances

Contextualizing phenomenology in event management research: Deciphering the meaning of event experiences

Purpose - Although the core phenomenon of events is the experiences and the meanings attached to them, there is limited management research on the experiential, existential and ontological dimensions of events. Phenomenology provides a sound philosophical framework for studying the multifaceted dimensions of experiences and associated meanings of events. However, quite surprisingly, phenomenology has not yet been systematically applied on the event management field. This conceptual paper aims to introduce phenomenology to the study of events, demonstrate its value for the field and encourage as well as guide its application on event management research. Design/methodology/approach - A review and synthesis of the main phenomenological streams of thought was undertaken in order to develop a research paradigm for the application of phenomenology on the event management field. Findings - The paper explains why phenomenology is needed in the study of events and their management, its conceptual underpinnings and streams of thought and finally suggests a research framework for conducting phenomenological studies in event management. Research limitations/implications - The consequences of the phenomenological perspective are delineated for explaining how the study of event meanings and experiences can be undertaken from this perspective. The limitations of phenomenology are noted such as the emphasis on ‘lifeworld’ subjectivity and subsequent difficulty to claim the generalizability of research findings. Practical implications - The suggested research framework can guide future event management research on how to apply phenomenology to the study of event experiences and meanings. On this basis, practitioners can get insight regarding how to develop and design events that optimize the perceived experiences of attendees. Originality/value - While the experiential paradigm and the phenomenological turn have been spread across many disciplines emphasizing the essence of lived experiences in a variety of human interactions and exchanges, the event management field lags behind. This is unfortunate and has to be addressed as the experiences and meanings shape the essence of events. Therefore, this conceptual paper hopes to inspire, encourage and guide event management researchers to embrace and apply the phenomenological perspective on their future research endeavors, which can profitably complement and expand the predominant research paradigms in the field
