Objectives: To identify ontology concepts from text documents for the construction of work process ontology. Methods: This study proposes a methodology to identify terms representing a work process ontology concept from a document. The methodology encompasses several key steps: document collecting, text pre-processing, term weighting and analysis, terms mapping, and domain expert relevance judgments.

Abstract:
In similarity-based constrained clustering, there have been various approaches on how to define the similarity between documents to guide the grouping of similar documents together. This paper presents an approach to use term-distribution statistics extracted from a small number of cue instances with their known classes, for term weightings as indirect distance constraint. As for distribution-based term weighting, three types of term-oriented standard deviations are exploited: distribution of a term in a collection (SD), average distribution of a term in a class (ACSD), and average distributio

Abstract:
Knowledge graphs (KGs) are widely used in the education domain to offer learners a semantic representation of domain concepts from educational content and their relations, termed as educational knowledge graphs (EduKGs). Previous studies on EduKGs have incorporated concept extraction and weighting modules. However, these studies face limitations in terms of accuracy and performance. To address these challenges, this work aims to improve the concept extraction and weighting mechanisms by leveraging state-of-the-art word and sentence embedding techniques.

This chapter discusses the concept of credit risk. Of all the risks that banks are exposed to, credit risk is the most important and the most intuitively obvious. It is important to remember that credit means more than simply loans. At the heart of financial transactions are credit exposures. For an economist, the function of a bank is maturity transformation and intertemporal transfers of resources. But in a world where debts were always repaid, these functions would be as mechanical as the transmission of water or electricity. It is the unpredictability of credit that differentiates banking

Weaknesses are exposed in all these arguments. For many of the arguments, it is shown that there is an equally strong parity argument for an opposite conclusion.

Abstract:
NUMO has adopted a volunteering approach to siting a geological repository for high-level radioactive waste (HLW). It is important for this process that the pros and cons of volunteers can be assessed from literature data in a clear and transparent manner, prior to the very careful selection of those sites that will be carried forward for more detailed characterisation. For this purpose, multi-attribute analysis (MAA) methodology has been developed that allows the technical assessment of criteria to be represented as scoring models. The trickier job of weighting different criteria involves exp

Abstract:
An objective evaluation of different propulsion concepts for naval frigates has been demonstrated. Based on an assumed operation profile and weighting of criteria stated herein, hybrid-propulsion arrangements incorporating electric drives have been observed to optimally meeting the specified requirements commonly observed across most navies. The demonstrated evaluation shows that the resultant propulsion plant configurations may not fully achieve all defined requirements, which are often conflicting, but represent a good compromise to best meet the operation requirements based on defined prior

Abstract:
Crowdsourced evaluation is a promising method for evaluating attributes of design concepts that require human input. One factor in obtaining good evaluations is the ratio of high-ability to low-ability participants within the crowd. In this paper we introduce a Bayesian network model capable of finding participants with high design evaluation ability, so that their evaluations may be weighted more than those of the rest of the crowd. The Bayesian network model also estimates a score of how well each design concept performs with respect to a design attribute without knowledge of the true scores

Abstract:
This paper focuses on the active vibration control of flexible rotors by piezo actuators located at the bearings. At first general relations are derived, that allow to specify the required power and dimensions of the actuators from the balance quality factor of the rotor and the stiffness of the system. Second, two control concepts, integral force feedback and robust control, are compared. The design procedure of the robust µ-synthesis controller including uncertainty modelling and selection of weighting functions is described. Experimental results obtained from a simple test rig are shown. Fi

Abstract:
Partial MaxSAT (PMS) generalizes SAT and MaxSAT by introducing hard clauses and soft clauses. PMS and Weighted PMS (WPMS) have many important real world applications. Local search is one popular method for solving (W)PMS. Recent studies on specialized local search for (W)PMS have led to significant improvements. But such specialized algorithms are complicated with the concepts tailored for hard and soft clauses. In this work, we propose a dynamic local search algorithm, which exploits the structure of (W)PMS by a carefully designed clause weighting scheme. Our solver SATLike adopts a local sea

Abstract:
Abstract For the Performance Contract philosophy, evaluating performance is an essential part of aligning interests in contracted relationships. Furthermore, it allows for assessing the effectiveness of contracted initiatives, enhancing efficiency by fostering competitiveness and autonomy. In the offshore drilling industry, NPT (Non-Productive Time) is commonly used as a metric for evaluating asset management performance. However, this indicator has many limitations that impact a robust evaluation of contractor and manufacturer management. To increase the consistency of performance evaluation

Abstract:
This comprehensive 3-day workshop focuses on refining statistical modeling and regression analysis skills by integrating advanced AI tools like ChatGPT with traditional software such as Stata. Participants will gain practical competencies in various regression techniques, including interaction effects (or 'moderation'), logistic regression, missing data, scale construction, transformations, weighting, and how to deal with regression assumptions, along with AI-powered assistance from ChatGPT to clarify concepts and troubleshoot commands.

Abstract:
In a real-world data set there is always the possibility, rather high in our opinion, that different features may have different degrees of relevance. Most machine learning algorithms deal with this fact by either selecting or deselecting features in the data preprocessing phase. However, we maintain that even among relevant features there may be different degrees of relevance, and this should be taken into account during the clustering process. With over 50 years of history, K-Means is arguably the most popular partitional clustering algorithm there is. The first K-Means based clustering algo

Abstract:
This project concerns the impacts of food hypersensitivity on people’s quality of life and the monetary value people assign to the removal of those impacts. Food hypersensitivities (FHS) are, in this report, defined as comprising food allergy, coeliac disease and food intolerance. Estimates of the economic value of removal of food hypersensitivity were generated from a stated preference (SP) survey in which people completed a discrete choice experiment (DCE). The DCE comprised of choices between (i) no change in respondents’ food hypersensitivity and (ii) the condition being removed for a spec
