Feeds as Query Result Serializations

Many Web-based data sources and services are available as feeds, a model that provides consumers with a loosely coupled way of interacting with providers. The current feed model is limited in its capabilities, however. Though it is simple to implement and scales well, it cannot be transferred to a wider range of application scenarios. This paper conceptualizes feeds as a way to serialize query results, describes the current hardcoded query semantics of such a perspective, and surveys the ways in which extensions of this hardcoded model have been proposed or implemented. Our generalized view of feeds as query result serializations has implications for the applicability of feeds as a generic Web service for any collection that is providing access to individual information items. As one interesting and compelling class of applications, we describe a simple way in which a query-based approach to feeds can be used to support location-based services

Fairness of Exposure in Rankings

Rankings are ubiquitous in the online world today. As we have transitioned from finding books in libraries to ranking products, jobs, job applicants, opinions and potential romantic partners, there is a substantial precedent that ranking systems have a responsibility not only to their users but also to the items being ranked. To address these often conflicting responsibilities, we propose a conceptual and computational framework that allows the formulation of fairness constraints on rankings in terms of exposure allocation. As part of this framework, we develop efficient algorithms for finding rankings that maximize the utility for the user while provably satisfying a specifiable notion of fairness. Since fairness goals can be application specific, we show how a broad range of fairness constraints can be implemented using our framework, including forms of demographic parity, disparate treatment, and disparate impact constraints. We illustrate the effect of these constraints by providing empirical results on two ranking problems.Comment: In Proceedings of the 24th ACM SIGKDD International Conference on Knowledge Discovery and Data Mining, London, UK, 201

DESIGN AND IMPLEMENTATION OF MOBILE NEWS SERVICES: SUPPORTING SOCIAL NETWORKING FEATURES

This paper discusses and implements features both for a mobile Web and for a mobile native application, capable to provide news services enriched with indicative social networking elements. The objective was to facilitate the involvement of mobile users to produce and upload new content on the News Website and to facilitate their participation in the promotion and evaluation of the existing content. A significant addition was the implementation of an application for the automatic storing of articles derived from external sources, such as RSS/Atom feeds and emails. The results of our work are primarily related with the investigation and understanding of serious technical challenges, as well as the eventual development of proper solutions regarding the support of the ‘participative relation’ of mobile users with news-oriented Web content

Experiences with Implementing a Spatial Decision Support System for Planning Snow Removal Operations

This paper discusses the development of a Web-based Intelligent Spatial Decision Support system that helps efficiently plan snow removal operations. The system is designed to integrate Web and geospatial analytical techniques for asset management, routing procedures and weather information to assist effective snow removal procedures. The system includes the knowledge from snow removal experts from Blackhawk County in Iowa and the cities of Cedar Falls and Waterloo, Iowa. It manages various resources efficiently by providing expert advice to assist complex decision making for efficient routing, optimal resource allocation, while monitoring live weather information. The system has been developed as a Web-based system to facilitate ubiquitous access and ease of use

Trigeiawriter: A content management system

The purpose of this project was to design and implement a Content Management System (CSM). TrigeiaWriter is a Content Management System for Trigeia.com, a web based magazine site. Since TrigeiaWriter is used for a web based magazine, it incorperates different roles for the users and these roles are authors, editors, and administrators
