Mūsdienās tiek ģenerēts un glabāts ārkārtīgi liels daudzums datu – sensoru dati, transakcijas, sociālo tīklu dati, audio, video ieraksti u.c. Šajos datos slēpjas noderīga informācija, ko var iegūt ar lielo datu analītikas palīdzību. Viens no svarīgākajiem rīkiem lielo datu analītikā ir datu vizualizēšana, kas ļauj efektīvāk aptvert lielu datu apjomu vizuāli un palīdz atklāt datos dažādas jaunas likumsakarības. Šajā darbā ir aplūkotas lielākās lielo datu vizualizēšanas problēmas kā arī to izplatītākie risinājumi, apskatīts Tableau datu vizualizāciju izveides rīks, izveidota Hadoop tehnoloģiju vide, kā arī iegūti un vizualizēti Twitter dati.
Osallistu, keskustele, vaikuta! – Näkökulmia sosiaaliseen televisioon ja livetviittaamiseen
2017
Tässä artikkelissa tarkastellaan nykymedialle tyypillistä yleisön osallistamisen, aktivoinnin ja vuorovaikutuksellisuuden pyrkimystä sosiaalisen television ja livetviittaamisen näkökulmasta. Käsitteet kietoutuvat virallisen hashtagin ympärille, jonka kautta televisio-ohjelmien tai muiden livetapahtumien yleisöt linkittävät itsensä osaksi tilapäistä hashtag-yhteisöä ja laajaa julkista keskustelua. Artikkelissa esitellään Twitterin live-käyttöä mediatapahtumaan osallistumisessa ja pohditaan, millaisia käyttömahdollisuuksia livetviittaamiseen ja sosiaaliseen televisioon liittyvät käytännöt voisivat tarjota opetusmetodeina. nonPeerReviewed

The Issue Arena of a Corporate Social Responsibility Crisis : The Volkswagen Case in Twitter

The focus is on capturing the issue as it evolved over time, the actors and sentiments expressed, and the responses of the organization.

Female unemployment in an emerging economy : A study of online social support as a coping strategy
2021
The increased use of social media has resulted in active participation of women on social media platforms, specifically Facebook, Twitter, and Instagram. However, very little research has been carried out, specifically, on how women cope with the challenges of unemployment using social media networks. Thus, many women resort to different means as a coping strategy during their unemployment. In the face of rapid diffusion of social platforms, it is unclear how women personality traits influence their use of the social media. Similarly, it is also unclear how women’s experiences with these social networks, as a medium of online social support, serve as a coping strategy in the period of unemp…

Towards a typology of negative engagement behavior in social media
2022
Extant literature on consumer engagement has focused on positive manifestations of the construct, rather than on its negative dimension. Yet, many brand interactions are negative in nature. The purpose of this conceptual study is to develop a typology of negative engagement behavior in social media by using the multi-grounded theory (MGT) approach on a sample of 12,429 tweets extracted from Twitter. The analysis shows that negative engagement behavior with a brand or service provider as the object focus or target can be categorized according to (a) the manifestation of the negative engagement and (b) the emotional intensity of the negative engagement. Four categories of negative engagement …
Neironu tīklu metodes kriptovalūtu vērtību prognozēšanai
2018
Kriptovalūtu tirgus nestabilitātes dēļ, pašam prognozēt, kā notiks vērtību svārstības ir gandrīz neiespējami. Tāpēc šajā darbā tiks apskatītas vairākas metodes, ar kuru palīdzību prognozēs dažādu kriptovalūtu vērtību tuvākajā nākotnē, izmantojot mākslīgos neironu tīklus. Darba mērķis ir salīdzināt dažādas metodes, kā analizēt kriptovalūtu datus un noteikt to vērtību tuvākajā nākotnē, balstoties gan uz dažādu kriptovalūtu vēsturisko informāciju, gan uz sociālā tīkla Twitter ierakstiem. Trenējot neironu tīklus, kuram tiek padoti sociālo tīklu dati apvienojumā ar kriptovalūtu informāciju, tika sasniegts pat 10%-15% pieaugums prognozēšanas precizitātei, salīdzinot ar parastu kriptovalūtu vēstur…
