Joukolla on suuri potentiaali, mutta tuntemattomalle yleis\u00f6lle annettu ongelmanratkaisu voi olla laadunhallinnan kannalta haastavaa. T\u00e4m\u00e4n tutkielman tavoitteena oli luoda yleiskuva joukkoistamisen laadunhallinnasta: perustella laadukkuuden merkityst\u00e4 ja siihen vaikuttavia tekij\u00f6it\u00e4, sek\u00e4 esitell\u00e4 menetelmi\u00e4 laadun hallitsemiseksi. Tutkimuksen tuloksia voidaan k\u00e4ytt\u00e4\u00e4 eri menetelmien valinnan tukena. Tutkielma toteutettiin kirjallisuuskatsauksena. Tutkimuksen aikana havaittiin, ett\u00e4 laatua voivat ennustaa osallistujien profiili, kuten kuinka hyv\u00e4 maine ratkaisijalla on, tai kuinka asiantunteva h\u00e4n on. T\u00e4m\u00e4n lis\u00e4ksi teht\u00e4v\u00e4n suunnittelu vaikuttaa: kuinka hyvin teht\u00e4v\u00e4 on m\u00e4\u00e4ritelty ja jyvitetty, millainen k\u00e4ytt\u00f6liittym\u00e4 on, ja millaisia palkintoja osallistujalle tarjotaan. Negatiivisesti laatuun voivat vaikuttaa tekij\u00e4n ep\u00e4eettisyys, ep\u00e4p\u00e4tevyys, pahantahtoisuus tai kognitiivinen vinouma. Laatua voidaan hallita useilla menetelmill\u00e4, jotka on jaettu suunnittelun- ja toiminnanaikaisiin. Suunnittelunaikaiset perustuvat siihen, ett\u00e4 teht\u00e4v\u00e4 on mahdollisimman hyvin suunniteltu, tai osallistuva tekij\u00e4 on esivalittu ominaisuuksiensa mukaan.

T\u00e4llaisia keinoja ovat muun muassa asiantuntijan arvio lopputuloksesta tai tuloksen vertaaminen yleisesti tunnettuun totuuteen. Usean menetelm\u00e4n k\u00e4ytt\u00f6 voi samanaikaisesti olla tarpeen, mutta monetkaan menetelm\u00e4t eiv\u00e4t sovi kaikkiin joukkoistamistarpeisiin.

It harnesses a crowd through an open invitation to solve a task. Crowdsourcing has a great potential, but by outsourcing problem solving to an unknown crowd may result into quality challenges. The motivation of the thesis was to create an overview of quality management in crowdsourcing: why quality is important, which factors affect quality, and how to manage quality. The results of this thesis can be used to support in choosing quality management methods. This thesis was conducted as a literature review. This study shows that quality can be predicted from the profile of contributors. In addition, task design has an impact: how well the assignment is defined and granulated, what kind of user interface is used and what incentives are offered for the contributors. Risks of bad quality can be unethical behavior, incompetency, maliciousness or cognitive bias of the contributor. Quality can be managed by several methods, which can be categorized into design-time and runtime methods. Design-time methods rely on the best possible design of the task, or the contributor is pre-selected by certain criteria. Runtime methods affect the quality when the task has already been presented to the contributors. Such means include for instance expert analysis or comparing the contribution to a gold standard. Using multiple methods parallelly can be beneficial but all methods are not suitable for all crowdsourcing pursues. Other challenges in quality management can be for instance the fact that a crowd's opinion may be misleading, or the difficulty to identify maliciousness of a contributor.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-09-02T04:48:47Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-09-02T04:48:47Z (GMT).
