Social-media monitoring for cold-start recommendations

Generating personalized movie recommendations to users is a problem that most commonly relies on user-movie ratings. These ratings are generally used either to understand the user preferences or to recommend movies that users with similar rating patterns have rated highly. However, movie recommenders are often subject to the Cold-Start problem: new movies have not been rated by anyone, so, they will not be recommended to anyone; likewise, the preferences of new users who have not rated any movie cannot be learned. In parallel, Social-Media platforms, such as Twitter, collect great amounts of user feedback on movies, as these are very popular nowadays. This thesis proposes to explore feedback shared on Twitter to predict the popularity of new movies and show how it can be used to tackle the Cold-Start problem. It also proposes, at a finer grain, to explore the reputation of directors and actors on IMDb to tackle the Cold-Start problem. To assess these aspects, a Reputation-enhanced Recommendation Algorithm is implemented and evaluated on a crawled IMDb dataset with previous user ratings of old movies,together with Twitter data crawled from January 2014 to March 2014, to recommend 60 movies affected by the Cold-Start problem. Twitter revealed to be a strong reputation predictor, and the Reputation-enhanced Recommendation Algorithm improved over several baseline methods. Additionally, the algorithm also proved to be useful when recommending movies in an extreme Cold-Start scenario, where both new movies and users are affected by the Cold-Start problem.

Asiakastyytyväisyyteen vaikuttavien tekijöiden tunnistaminen sosiaalisen median seurantapalvelun ja kriittisten tapausten tekniikan avulla

Tutkimuksen tavoitteena on muodostaa liikkeenjohdon päätöksentekoa tukeva toimintatapa, jonka avulla pystytään keräämään ja suodattamaan sosiaalisesta mediasta olennainen asiakastyytyväisyyden muodostumiseen vaikuttava informaatio. Tavoitteena on myös täsmentää sosiaalisen median viestien tarkastelutapaa ja tarjota liikkeenjohdolle käytännönläheinen ja vaihtoehtoinen tiedonkeruumenetelmä perinteisten asiakastyytyväisyyskyselyiden rinnalle. Tutkimuksen case-yrityksenä käytetään Fox International Channels Oy:tä, joka alkuvuodesta 2012 hankki SuomiTV:n ja lanseerasi tämän tilalle uuden FOX-kanavan. Sosiaalisen median viestit kerätään sosiaalisen median seurannan avulla ja kerättyä aineistoa tarkastellaan kriittisten tapausten tekniikan avulla.Tämän tutkimuksen perusteella voidaan todeta, että on olemassa valtava määrä käsittelemätöntä tietoa, jota keräämällä, suodattamalla ja analysoimalla voidaan kerätä tavoitteita tukevaa relevanttia informaatiota. Tutkimuksessa tulee ilmi, että viestit sisältävät paljon ironiaa, slangia, sarkasmia ja metaforia, minkä takia automaattinen hakusanoihin perustuva seuranta- ja analysointipalvelu ei riitä syvällisen ymmärryksen luomiseen. Yrityksen ulkopuolinen tieto ja sosiaalisen median viestit ovat puhtaimmillaan hyvin tärkeää ulkoista informaatiota yrityksille, mitä hyväksikäyttämällä voidaan luoda kilpailuetua pidemmällä aikavälillä.

Business modeling in turbulent environments

This study presents an agile tool set for the business modeling in companies, entering the turbulent environment. The study’s aim is to explore business modeling techniques and their tooling by utilizing a case study of a Finnish media monitoring company, expanding to the Russian market. This work proposes a tailored “two-approach” of business modeling development that analyzes both the past and future conditions of two key factors of business modeling for companies – internal and external environments. The study explores a case company by investigating the benefits and disadvantages of firm’s present business modeling tools, developing a new tooling and applying it to the case company. Among primary data utilization, such as interviews with media monitoring industry analysts and representatives of the competing companies, and academic experts, study leans up on the comprehensive analysis of Russian media monitoring niche and its players. This study benefits the business modeling research area and combines traditional analysis tools, such as market, PESTLE and competitor analyses, in a systemic manner, with the business modeling techniques. This transformation proceeds through applying of the integrated scenario, heat map and critical design issues’ analyses in the societal, industrial and competitive context of turbulent environments. The practical outcome of this approach is the development of agile business modeling tool set, customizable by company’s requirements.

Los efectos de la participación política ciudadana en Colombia: la revocatoria de mandato en Boyacá

La revocatoria de mandato es una herramienta de participación política ciudadana en Colombia establecida hace ya más de veinte años. Sin embargo, y a pesar de que ha sido implementada en 146 casos, ningún gobernante ha sido revocado o ratificado por este medio en el país. Este hecho ha motivado varias investigaciones que se han centrado en los problemas operativos, normativos y las dificultades en la implementación de la herramienta. Este trabajo busca ir más allá y centrarse en los efectos políticos y sociales que afectan, de manera positiva o negativa, esta herramienta de participación política ciudadana. Siendo una herramienta que involucra directamente a los ciudadanos con la política local, las acciones que se lleven a cabo durante todo el proceso pueden afectar a la población. Esto se puede afirmar si se tiene en cuenta que la historia política colombiana ha estado permeada por el autoritarismo y el clientelismo, donde actores poderosos a nivel local, pertenecientes a oligopolios políticos, se encuentran legitimados por características históricas para adelantar acciones que afectan la seguridad, tranquilidad e integridad de la población. El análisis involucra tres procesos de revocatoria de mandato en el departamento de Boyacá durante el periodo 2008-2011: Tunja, Samacá y Somondoco; resaltando el papel que cada actor juega en el respectivo proceso de revocatoria, así como sus motivaciones para ser parte de él y las acciones que adelanten para asegurar el éxito o fracaso de esta herramienta. Para ello se utilizó una metodología cualitativa, consistente en monitoreo de medios y entrevistas semiestructuradas a los diferentes actores de los procesos, lo cual permite reconstruir los casos de estudio.

Virtual Celebrator Machine

There has been a huge growth of social network in the recent years. This trend does not only allow us to get connected and share the information in an efficient way, but also reveals some potential beneficial in dealing with several social issues, such as earthquake detection, social spam detection, flu pandemic tracking, media monitoring, etc. In this paper, we propose a new way of utilizing social network. By implementing what is called a Virtual Celebrator Machine (VCM), we are able to let everyone who has connection with this machine in term of social networking be able to share their cultural experience and points of view about certain social events locally or globally. In that way, we provide a way to reinforce the relationship and connection between people virtually, which, we believe, would help to flourish cultural heritage preservation.
