Implementing an open data system and showing its benefits

Open data refers to publishing data on the web in machine-readable formats for public access. Using open data, innovative applications can be developed to facilitate people‟s lives. In this thesis, based on the open data cases (discussed in the literature review), Open Data Lappeenranta is suggested, which publishes open data related to opening hours of shops and stores in Lappeenranta City. To prove the possibility of creating Open Data Lappeenranta, the implementation of an open data system is presented in this thesis, which publishes specific data related to shops and stores (including their opening hours) on the web in standard format (JSON). The published open data is used to develop web and mobile applications to demonstrate the benefits of open data in practice. Also, the open data system provides manual and automatic interfaces which make it possible for shops and stores to maintain their own data in the system. Finally in this thesis, the completed version of Open Data Lappeenranta is proposed, which publishes open data related to other fields and businesses in Lappeenranta beyond only stores‟ data.

A systematic mapping study on open data

This thesis presented the overview of Open Data research area, quantity of evidence and establishes the research evidence based on the Systematic Mapping Study (SMS). There are 621 such publications were identified published between years 2005 and 2014, but only 243 were selected in the review process. This thesis highlights the implications of Open Data principals’ proliferation in the emerging era of the accessibility, reusability and sustainability of data transparency. The findings of mapping study are described in quantitative and qualitative measurement based on the organization affiliation, countries, year of publications, research method, star rating and units of analysis identified. Furthermore, units of analysis were categorized by development lifecycle, linked open data, type of data, technical platforms, organizations, ontology and semantic, adoption and awareness, intermediaries, security and privacy and supply of data which are important component to provide a quality open data applications and services. The results of the mapping study help the organizations (such as academia, government and industries), re-searchers and software developers to understand the existing trend of open data, latest research development and the demand of future research. In addition, the proposed conceptual framework of Open Data research can be adopted and expanded to strengthen and improved current open data applications.

Alueverkkojen yhteisöllisyyden edistäminen, vaihtoehtojen arviointi ja yhteisöverkkoportaalin toteutus

Internetin yhteisöpalvelut ovat saavuttaneet suuren suosion. Ne mahdollistavat digitaalisten yhteisöjen ja yhteisöllisyyden tunteiden aikaansaamisen käyttäjien välille. Kehittyneet verkkoyhteydet ja sisältötekniikat ovat antaneet mahdollisuuden monipuolisten vuorovaikutustyökalujen toteuttamiseksi. Sähköinen yhteisöllisyys on nouseva trendi, joka tukee arkipäivästä todellisuutta. Verkkojen paikallinen kehitys, niin laajakaistan kuin erilaisten alueverkkojen avulla on nostanut ajatuksia luoda myös paikallista yhteisöllisyyttä globaalien yhteisöpalvelujen rinnalle. Nopeiden alueverkkojen laajentuminen ovat tuoneet edistyneet verkkoyhteydet niin lähiöihin kuin taajamienkin ulkopuolelle. Avointen alueverkkojen mallissa verkko ja palvelukerros ovat eriytetty toisistaan. Ulkopuoliset palveluntarjoajat voivat tarjota palveluitaan suoraan alueverkon käyttäjille lähempänä verkkotasoa, verrattuna perinteiseen yhden verkkooperaattorin malliin. Tämä mahdollistaa uusien innovatiivisempien palveluiden kehittelyn. Tässä diplomityössä tutkittiin mahdollisuuksia joilla voidaan edistää yhteisöllisyyttä paikallisissa alueverkoissa ja hyödyntää niiden paikallista suorituskykyä, sekä resursseja palveluiden toteutuksessa. Työssä selvitettiin ensin mistä käsitteet yhteisö ja yhteisöllisyys ovat muodostuneet. Selvityksen pohjalta tutkittiin mitä teknisiä menetelmiä on yhteisöjen ja yhteisöllisyyden tunteen aikaansaamiseksi olemassa. Selvityksen tuloksena syntyi teknologinen tiekartta tietoverkkoyhteisöllisyyteen, sekä sosiaalisten palvelualustojen luokittelukaavio, joiden tarkoitus on yhdessä kuvastaa yhteisöllisyyttä tukevia palvelumahdollisuuksia. Työn viimeisessä vaiheessa toteutettiin yhteisöllinen alueverkkopalvelu, sekä yhteisövalvontajärjestelmä – lisäarvopalvelukonsepti, jotka pyrkivät hyödyntämään paikallisen alueverkon tarjoamaa suorituskykyä ja resursseja.

Front end development for building automation systems using JavaScript Frameworks

Automation technologies are widely acclaimed to have the potential to significantly reduce energy consumption and energy-related costs in buildings. However, despite the abundance of commercially available technologies, automation in domestic environments keep on meeting commercial failures. The main reason for this is the development process that is used to build the automation applications, which tend to focus more on technical aspects rather than on the needs and limitations of the users. An instance of this problem is the complex and poorly designed home automation front-ends that deter customers from investing in a home automation product. On the other hand, developing a usable and interactive interface is a complicated task for developers due to the multidisciplinary challenges that need to be identified and solved. In this context, the current research work investigates the different design problems associated with developing a home automation interface as well as the existing design solutions that are applied to these problems. The Qualitative Data Analysis approach was used for collecting data from research papers and the open coding process was used to cluster the findings. From the analysis of the data collected, requirements for designing the interface were derived. A home energy management functionality for a Web-based home automation front-end was developed as a proof-of-concept and a user evaluation was used to assess the usability of the interface. The results of the evaluation showed that this holistic approach to designing interfaces improved its usability which increases the chances of its commercial success.

Information integration and its impacts on logistics performance - Using information technology and systems to facilitate information integration

Fast changing environment sets pressure on firms to share large amount of information with their customers and suppliers. The terms information integration and information sharing are essential for facilitating a smooth flow of information throughout the supply chain, and the terms are used interchangeably in research literature. By integrating and sharing information, firms want to improve their logistics performance. Firms share information with their suppliers and customers by using traditional communication methods (telephone, fax, Email, written and face-to-face contacts) and by using advanced or modern communication methods such as electronic data interchange (EDI), enterprise resource planning (ERP), web-based procurement systems, electronic trading systems and web portals. Adopting new ways of using IT is one important resource for staying competitive on the rapidly changing market (Saeed et al. 2005, 387), and an information system that provides people the information they need for performing their work, will support company performance (Boddy et al. 2005, 26). The purpose of this research has been to test and understand the relationship between information integration with key suppliers and/or customers and a firm’s logistics performance, especially when information technology (IT) and information systems (IS) are used for integrating information. Quantitative and qualitative research methods have been used to perform the research. Special attention has been paid to the scope, level and direction of information integration (Van Donk & van der Vaart 2005a). In addition, the four elements of integration (Jahre & Fabbe-Costes 2008) are closely tied to the frame of reference. The elements are integration of flows, integration of processes and activities, integration of information technologies and systems and integration of actors. The study found that information integration has a low positive relationship to operational performance and a medium positive relationship to strategic performance. The potential performance improvements found in this study vary from efficiency, delivery and quality improvements (operational) to profit, profitability or customer satisfaction improvements (strategic). The results indicate that although information integration has an impact on a firm’s logistics performance, all performance improvements have not been achieved. This study also found that the use of IT and IS have a mediocre positive relationship to information integration. Almost all case companies agreed on that the use of IT and IS could facilitate information integration and improve their logistics performance. The case companies felt that an implementation of a web portal or a data bank would benefit them - enhance their performance and increase information integration.
