User session level diverse reranking of search results
2018
Most Web search diversity approaches can be categorized as Document Level Diversification (DocLD), Topic Level Diversification (TopicLD) or Term Level Diversification (TermLD). DocLD selects the relevant documents with minimal content overlap to each other. It does not take the coverage of query subtopics into account. TopicLD solves this by modeling query subtopics explicitly. However, the automatic mining of query subtopics is difficult. TermLD tries to cover as many query topic terms as possible, which reduces the task of finding a query's subtopics into finding a set of representative topic terms. In this paper, we propose a novel User Session Level Diversification (UserLD) approach bas…
Listwise Collaborative Filtering
2015
Recently, ranking-oriented collaborative filtering (CF) algorithms have achieved great success in recommender systems. They obtained state-of-the-art performances by estimating a preference ranking of items for each user rather than estimating the absolute ratings on unrated items (as conventional rating-oriented CF algorithms do). In this paper, we propose a new ranking-oriented CF algorithm, called ListCF. Following the memory-based CF framework, ListCF directly predicts a total order of items for each user based on similar users' probability distributions over permutations of the items, and thus differs from previous ranking-oriented memory-based CF algorithms that focus on predicting th…
ISSUES ON THE POSITION OF EUROPEAN EASTERN COUNTRIES IN WORLD RANKINGS INCLUDING ELEMENTS OF TAXATION
2012
Taxation is an essential component of any nation. Taxation, with its economic and social implications, is taken into account when the world rankings are made. The level of fiscal pressure, the design of the tax system, the number of taxes, the relationship between taxpayers with the fiscal administration, the principles of taxation, the existence of a real partnership between the taxpayer and the state are a part of fiscal elements that determine attractiveness or rejection from a particular country. Without claiming an exhaustive approach, our work presents some fiscal aspects from Eastern European countries found in world rankings, by emphasizing the influence of these factors on the posi…
Sensory testing in new product development: working with children
2015
Abstract This chapter aims at briefly reviewing applications of sensory descriptive testing methods with children, as well as their limits in relation to the cognitive development of children. Children’s sensory perceptions and preferences may differ from those of adults, which may make working directly with children a must for successful product development, at least at some stages of product development. However, most reported studies with children have characterized their preferences. Some studies have used discrimination tests and ranking tasks to gain knowledge about differences among products, or about sensory abilities development. A much smaller number of studies have involved child…
Can we automate expert-based journal rankings? Analysis of the Finnish publication indicator
2020
The publication indicator of the Finnish research funding system is based on a manual ranking of scholarly publication channels. These ranks, which represent the evaluated quality of the channels, are continuously kept up to date and thoroughly reevaluated every four years by groups of nominated scholars belonging to different disciplinary panels. This expert-based decision-making process is informed by available citation-based metrics and other relevant metadata characterizing the publication channels. The purpose of this paper is to introduce various approaches that can explain the basis and evolution of the quality of publication channels, i.e., ranks. This is important for the academic …
Weighted and unweighted distances based decision tree for ranking data
2018
Preference data represent a particular type of ranking data (widely used in sports, web search, social sciences), where a group of people gives their preferences over a set of alternatives. Within this framework, distance-based decision trees represent a non-parametric tool for identifying the profiles of subjects giving a similar ranking. This paper aims at detecting, in the framework of (complete and incomplete) ranking data, the impact of the differently structured weighted distances for building decision trees. The traditional metrics between rankings don’t take into account the importance of swapping elements similar among them (element weights) or elements belonging to the top (or to …
Yhteiskuntakuvaus Ian Rankinin romaanissa Black and Blue
2011
Tutkin työssäni Ian Rankinin dekkarin Black and Blue yhteiskuntakuvausta, jossa menetelmällisenä pohjana käytän kulttuurintutkimuksen eri teorioita. Tutkin miten yhteiskunta ja sen instituutiot näyttäytyvät romaanin luomassa maailmassa. Esittelen kirjan representoiman yhteiskunnan tyypillisiä edustajia sekä yksilöinä että ryhminä. Tutkin kirjan yhteiskuntakuvausta myös dekkarin konventionaalisten osien ilmenemisen mukaan, kuten rikos tapahtumana, uhri ja syyllinen henkilöinä ja tutkiva poliisi tapahtumien analysoijana. Black and Blue on modernin yhteiskuntakriittisen dekkarin edustaja, ja sen yhteiskuntakuvaus nousee dekkarin konventionaalisia osia tärkeämmäksi. Kertomuksen pääosassa ei enä…
Organisational Legitimation Strategies in Social Media : How Business Schools Address Declining Ranking
2023
Public relations scholarship has drawn on organisational legitimacy theory to show how organisations appeal to stakeholders’ acceptance of their existence and importance in society. Studies have shown how different types of organisations utilise communication strategies in social media to gain legitimacy. This chapter contributes to public relations research by examining how a sample of business schools implemented legitimation strategies in their social media posts when their legitimacy was threatened. The findings show that when ten world-class European business schools faced declining institutional rankings between 2016 and 2019, they made use of four legitimation strategies—authorisatio…
«Cité ou oublié» : les supports de la notoriété des professeurs en sciences de gestion vus à travers Google Scholar
2011
Standards for the evaluation of management scholars lead more and more to exclude forms of scientific production other than the articles published in international scientific journals. The aim of this paper is to test the validity of these norms by analyzing the production of all university professors in management science, based on the «influen- tial» publications in Google Scholar. The articles published in internation- al journals represent only 35 % of in- fluential publications and collect only 40.2 % of citations. Books still repre- sent a very important part and the in- fluence of the different media varies widely across sub-disciplinary fields (finance, marketing, etc.). This articl…
