Finding Tours for a Set of Interests
2018
This paper addresses a novel tour discovery problem in the domain of travel search. We create a ranking of tours for a set of travel interests, where a tour is a group of city documents and a travel interest is a query. While generating and ranking tours, it is aimed that each interest (from the interest set) is satisfied by at least one city in a tour and the distance traveled to cover the tour is not too large. Firstly, we generate tours for the interest set, by utilizing the available ranking of cities for the individual interests and the distances between the cities. Then, in absence of existing methods directly related to our problem, we devise our novel techniques to calculate ranking…
Building Composite Indicators With Unweighted-TOPSIS
2023
Composite indicators have been widely used in a large number of fields, including innovation and entrepreneurship as a useful tool for conveying summary information about overall performance in a relatively simple way. The construction of composite indicators implies several stages concerning collection of data, selection of criteria and individual indicators, normalization and weighting of criteria and indicators, aggregation, and comparison of overall performance of the alternatives or options. This article aims at contributing to the construction of synthetic indicators by showing with a real example, how the proposed methodology can overcome the problem of the establisment of the decisi…
An empirical approach for ranking environmental and energy saving measures in the hotel sector
2009
The energy demand of the hotel sector of an Italian region is here utilized for hierarchizing, by means of an empirical method, efficient measures devoted to energy saving and reduction of CO2 emissions. Due to the large number of consumers present in the selected territorial area and the lack in detailed data, the energy demand assessment is here carried out by the analysis of a sample of representative consumers. A short set of indexes, referring to energy and environmental performances, are defined and calculated for different clusters of hotels, grouped on the basis of site characteristics, opening periods, number of beds, and building age. Such indexes are utilized to establish lists o…
Visual Re-Ranking for Multi-Aspect Information Retrieval
2017
We present visual re-ranking, an interactive visualization technique for multi-aspect information retrieval. In multi-aspect search, the information need of the user consists of more than one aspect or query simultaneously. While visualization and interactive search user interface techniques for improving user interpretation of search results have been proposed, the current research lacks understanding on how useful these are for the user: whether they lead to quantifiable benefits in perceiving the result space and allow faster, and more precise retrieval. Our technique visualizes relevance and document density on a two-dimensional map with respect to the query phrases. Pointing to a locat…
Superposing significant interaction rules (SSIR) method: a simple procedure for rapid ranking of congeneric compounds
2020
The Superposing Significant Interaction Rules (SSIR) method is revised and implemented. The method is a simple combinatorial procedure, which deals with in situ generated rules among a dichotomized congeneric molecular family, selecting the most probabilistically relevant ones. The mere counting of the number of relevant rules attached to new compounds generates a molecular ranking useful for database filtering, refinement and prediction. The algorithm only needs for a symbolic molecular representation and this allows for mining the database in a confidential manner. Third parties will not know the real compounds that are on the way to be worked out. The procedure is tested for a complete s…
Ranking-based Ties Social Networks : an illustration based on a system of Fashion Capital Cities in the world.
2012
Our paper aims to apply a non-conventional Social Network Analysis to a network generated from an initial sorting of data with mere order. The aim is to test whether and how one relationship set 'conveniently' generated by the ranking is able to provide a coherent system of interactions with possible practical and theoretical utility. We consider a system of city distributions where we focus on ¿Ranking-Based Ties¿ social networks, considering a system of 'objects' of the same class that would be able to interact. The objects in question are ordered according to their 'performance' in a particular ranking. According to a survey developed by Global Langu…
How do journals of different rank instruct peer reviewers? Reviewer guidelines in the field of management
2020
Current knowledge on peer review consists of general formulations of its goals and micro level accounts of its practice, while journals’ attempts to guide and shape peer review have hardly been investigated so far. This article addresses this gap by studying the content of the reviewer guidelines (RG) of 46 journals in the field of management, as editors may use guidelines to nudge reviewers considering all relevant criteria, properly, and consistently with the needs of the journal. The analysis reveals remarkable differences between the instructions for reviewers of journals of different rank. Average and low rank journals mostly use evaluation forms, they emphasize the empirical contribut…
RANKING DECISION MAKING UNITS BY MEANS OF SOFT COMPUTING DEA MODELS
2011
This paper presents a method for ranking a set of decision making units according to their level of efficiency and which takes into account uncertainty in the data. Efficiency is analysed using fuzzy DEA techniques and the ranking is based on the statistical analysis of cases that include representative situations. The method enables the removal of the sometimes unrealistic hypothesis of a perfect trade-off between increased inputs and outputs. This model is compared with other DEA models that work with imprecise or fuzzy data. As an illustration, we apply our ranking method to the evaluation of a group of Spanish seaports, as well as teams playing in the Spanish football league. We compar…
CLUSTER OF COUNTRIES ANALYSIS BY RESPONSIBLE COMPETITIVENESS, NATIONAL COMPETITIVENESS AND CORRUPTION
2008
The Global Competitiveness Report, the State of Responsible Competitiveness and the Global Corruption Barometer elaborate annually a countries ranking that emphasize the progress or regress of each country. Using this reports the paper try to make a clusters analysis of world country by responsible competitiveness, national competitiveness and corruption. The main idea of this paper is to split the countries in three categories of clusters - innovators, asserters and beginners - in relation between responsible competitiveness and national competitiveness - and - stars, asserters and beginners - in relation between corruption and national competitiveness. Within the three clusters, countries…
Expert-based versus citation-based ranking of scholarly and scientific publication channels
2016
Abstract The Finnish publication channel quality ranking system was established in 2010. The system is expert-based, where separate panels decide and update the rankings of a set of publications channels allocated to them. The aggregated rankings have a notable role in the allocation of public resources into universities. The purpose of this article is to analyze this national ranking system. The analysis is mainly based on two publicly available databases containing the publication source information and the actual national publication activity information. Using citation-based indicators and other available information with association rule mining, decision trees, and confusion matrices, …
