As more people tweet, check-in and share pictures and videos of their daily experiences in the city, new opportunities arise to understand urban activity. When aggregated, these data can uncover invaluable local insights for local stakeholders such as journalists, first responders and city officials. To better understand the needs and requirements for this kind of aggregation tools, we perform ...

I propose a new axiom on the aggregation of individual yes/no judgments on propositions into collective judgments: each collective judgment depends only on people’s judgments on relevant propositions. This contrasts with classical independence: each collective judgment depends only on people’s judgments on the current proposition. I generalize the premise-based and sequential-priority rules to ...

The role of aggregation in natural language generation is to combine two or more linguistic structures into a single sentence. The task is crucial for generating concise and readable texts. We present an efficient algorithm for automatically learning aggregation rules from a text and its related database. The algorithm treats aggregation as a set partitioning problem and uses a global inference...

This paper targets the area of business Information System (IS) decision making, where accountable and understandable decision support is needed for all involved stakeholders. When information systems investments are evaluated based on applying different dimensions or attributes to the available alternatives the results have to be consolidated into a single ranking to provide a base for the inv...

We consider the issue of update in settings for preference aggregation under preference changes. While the traditional problem formulation of preference aggregation assumes a fixed set of preference orders and a fixed set of domain elements we investigate how an aggregated preference order has to be updated when the input orders are dynamic. Our analysis shows that for even for some simple aggr...

Endriss et al. [26] initiated the complexity-theoretic study of problems related to judgment aggregation. We extend their results for manipulating two specific judgment aggregation procedures to a whole class of such procedures, namely to uniform premise-based quota rules. In addition, we consider incomplete judgment sets and the notions of top-respecting and closeness-respecting preferences in...

BACKGROUND Health-related quality of life (HRQL) scores are used extensively to quantify the effectiveness of medical interventions. Societal preference-based HRQL scores aim to produce societal valuations of health by aggregating valuations from individuals in the general population, where each aggregation procedure embodies different ethical principles, as explained in social choice theory. ...

This article establishes that Arrow’s General Possibility Theorem has only indirect application to engineering design. Arrow’s Theorem states that there can be no consistent, equitable method for social choice. Many engineering design decisions are based on the aggregation of preferences. The foundation of many engineering decision methods is the explicit comparison of degrees of preference, a ...
