ments [2,5,6]. TEPs provide simplified representations of actual processes based on cardinal attributes. These attributes are developed using measured and/or estimated data in models that focus on factors judged to be crucial. The Human Toxicity Potential (HTP) is a quantitative TEP that was introduced by Guinée and Heijungs [1] to reflect the potential harm of a unit quantity of chemicals rele...

There has been a growing interest in mining frequent itemsets in relational data with multiple attributes. A key step in this approach is to select a set of attributes that group data into transactions and a separate set of attributes that labels data into items. Unsupervised and unrestricted mining, however, is stymied by the combinatorial complexity and the quantity of patterns as the number ...

The success of distributed and semantic-enabled systems relies on the use of up-to-date ontologies and mappings between them. However, the size, quantity and dynamics of existing ontologies demand a huge maintenance effort pushing towards the development of automatic tools supporting this laborious task. This article proposes a novel method, investigating different types of similarity measures,...

Modern embedding methods focus only on the words in the text. The word or sentence embeddings are trained to represent the semantic meaning of the raw texts. However, many quantified attributes associated with the text, such as numeric attributes associated with Yelp review text, are ignored in the vector representation learning process. Those quantified numeric attributes can provide important...

A hedonic price function for wine is estimated using Swedish data, 1989-91. Implicit prices for quality attributes are determined not from a regression of variety price on a vector of quality attributes, but rather from a regression of quantity sold (adjusted for weeks of availability) on price and quality attributes. Such a ‘reduced form’ is justified by the assumption that prices and attribut...

Quantity discount pricing is a common practice used by business-to-business and business-toconsumer companies. A key characteristic of quantity discount pricing is that the marginal price declines with higher purchase quantities. In this paper, we propose a choice-based conjoint model for estimating consumer-level willingness-to-pay (WTP) for varying quantities of a product and for designing op...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

In this paper we propose a methodology to measure the characteristics and composition of intermediate products using productivity indicators based on directional distance functions. We evaluate how quality attributes interact with the quantity level in grapes production, and find evidence of a trade-off between quantity and aggregate quality for Chardonnay. ∗Dipartimento di Scienze Economiche —...

Decision analysis evaluates options in terms of their expected utility, the expected amount of good. Many regulatory decisions require estimates of utility, which is not the same as monetary outcomes or other objectively measurable quantities. I review some of the problems of utility measurement for consequences (hence “utilitarian”) and suggest possible solutions. Contingent valuation (CV), a ...
