Investigating serendipity in recommender systems based on real user feedback
2018
Over the past several years, research in recommender systems has emphasized the importance of serendipity, but there is still no consensus on the definition of this concept and whether serendipitous items should be recommended is still not a well-addressed question. According to the most common definition, serendipity consists of three components: relevance, novelty and unexpectedness, where each component has multiple variations. In this paper, we looked at eight different definitions of serendipity and asked users how they perceived them in the context of movie recommendations. We surveyed 475 users of the movie recommender system, MovieLens regarding 2146 movies in total and compared tho…
Guidelines for improving the contextual relevance of field surveys: the case of information security policy violations
2014
The information systems (IS) field continues to debate the relative importance of rigor and relevance in its research. While the pursuit of rigor in research is important, we argue that further effort is needed to improve practical relevance, not only in terms of topics, but also by ensuring contextual relevance. While content validity is often performed rigorously, validated survey instruments may still lack contextual relevance and be out of touch with practice. We argue that IS behavioral research can improve its practical relevance without loss of rigor by carefully addressing a number of contextual issues in instrumentation design. In this opinion article, we outline five guidelines – …
A two-step, user-centered approach to personalized tourist recommendations
2017
Geo-localized, mobile applications can simplify a tourist visit, making the relevant Point of Interests more easily and promptly discernible to users. At the same time, such solutions must avoid creating unfitting or rigid user profiles that impoverish the users' options instead of refining them. Currently, user profiles in recommender systems rely on dimensions whose relevance to the user is more often presumed than empirically defined. To avoid this drawback, we build our recommendation system in a two-step process, where profile parameters are evaluated preliminarily and separately from the recommendations themselves. We describe this two-step evaluation process including an initial surv…
Recommending Serendipitous Items using Transfer Learning
2018
Most recommender algorithms are designed to suggest relevant items, but suggesting these items does not always result in user satisfaction. Therefore, the efforts in recommender systems recently shifted towards serendipity, but generating serendipitous recommendations is difficult due to the lack of training data. To the best of our knowledge, there are many large datasets containing relevance scores (relevance oriented) and only one publicly available dataset containing a relatively small number of serendipity scores (serendipity oriented). This limits the learning capabilities of serendipity oriented algorithms. Therefore, in the absence of any known deep learning algorithms for recommend…
Emerging and Traditional Donors in the ‘Post-Busan’ Context: Assessing Brazil’s and Finland’s Cooperation Practices in Mozambique
2015
At the same time as the ‘emerging donors’ have gained relevance in the development cooperation system, they have also challenged established principles of aid. This article compares Brazil's and Finland's development cooperation practices in the light of recent global tendencies in the aid architecture. Based on empirical research carried out in Mozambique, Brazil, and Finland, the article gives a detailed review of the institutional and historical settings of each bilateral cooperation. The authors then analyse how two central concepts reinforced during the Busan High Level Forum have been put into practice by a ‘new emerging’ and a ‘traditional Nordic’ donor. For ‘development effectivenes…
La aplicación del derecho extranjero en iberoamérica y la unión europea: : paralelismos desde la diferencia
2021
The potential application of a foreign law constitutes the logical outcome of any Private International Law? system. However, and despite its relevance, this issue lacks a common answer in the EU. In contrast to this, the analysis of the solutions drafted in Latin America as regards this issue grants a novel dimension to the European situation on this issue as well as highlights a meritorious reality that shows a high and very relevant degree of harmonization
Kehittämishankkeet korkeakoulutuksen työelämärelevanssin edistäjänä
2020
Tiivistelmä Muuttuvan työelämän tarpeet ohjaavat entistä painokkaammin kehittämään yhteistyötä korkeakoulutuksen ja työelämän välillä sekä vahvistamaan jatkuvan oppimisen kulttuuria. Yksilötasolla paremmat yleiset työelämätaidot avaavat uusia työllistymismahdollisuuksia ja tukevat opiskelijaa opitun soveltamisessa. Yhteiskunnan tasolla korkeakoulujen työelämäyhteyksien kehitystyöllä varmistetaan työvoiman saatavuutta ja nopeutetaan työllistymistä. Tässä tutkimuksessa tarkastellaan käynnissä olevia ja jo päättyneitä korkeakoulutuksen ja työelämän väliseen yhteistyöhön liittyviä kehittämishankkeita (n=12), niissä tunnistettavia erilaisia työelämäyhteyksien kehittämiseen liittyviä malleja sekä…
Goodwill impairments and the value relevance of goodwill of the small listed companies in Finland
2016
Tutkimuksen tavoitteena on tarkastella, miten liikearvon arvo määräytyy ja onko liikearvo arvorelevanttia. Kohdeyritysten taloudellisten tietojen ja niiden analysoinnin pohjalta on tarkoituksena selvittää, onko liikearvon ja yrityksen markkina-arvon välillä yhteys sekä miten liikearvon määrä on vaihdellut kohdeyritysten taseissa vuosina 2007-2014. Tavoitteena on myös selvittää, miten markkinat suhtautuvat liikearvon arvonalentumiskirjauksiin. Tutkimusmenetelmä on kvantitatiivinen tutkimus, jossa on myös ominaispiirteitä field-tutkimuksesta. Tutkimusaineisto koostuu kirjallisuuden lisäksi kohdeyritysten tilinpäätöstiedoista sekä muusta taloudellisesta informaatiosta, kuten pörssikurssitiedoi…
Complex Authority Network Interactions in the Common Information Sharing Environment
2019
European authorities collaborate as a community toward a coherent approach of situational understanding and open trust base information sharing. Innovation in multi-stakeholder collaboration networks involve complex collaboration between user community members, providing cross-sector, cross-border and cross-authority interaction and information sharing for collaborative situation awareness, and cooperation to increase safety and security. This study analyses data consisting of elements of use cases, collected from EU funded innovation projects. These were placed in a table based on similarity, difference and relevance to produce a classification. The results of this study indicate that use …
Teenage Violence Toward Parents – in Search of the Theoretical Bases of a Research Tool
2020
The article contains an analysis of results of the available research on the phenomenon of children’s violence toward their parents. The main purpose of this interpretation is to search for the theoretical structure of a prepared research tool, initially called the Teen Violence Scale Toward Parents (TVSTP). The subject of the analyzes were works and research reports as well as police statistics containing information on the phenomenon of domestic violence, including teenage violence toward parents. As a result of the analysis, the theoretical function of the proposed research tool was distinguished, referring to types of violence possible to diagnose within this area. The proposed tool was…
