Proceedings of the 3rd Open Source Geospatial Research & Education Symposium OGRS 2014

The third Open Source Geospatial Research & Education Symposium (OGRS) was held in Helsinki, Finland, on 10 to 13 June 2014. The symposium was hosted and organized by the Department of Civil and Environmental Engineering, Aalto University School of Engineering, in partnership with the OGRS Community, on the Espoo campus of Aalto University. These proceedings contain the 20 papers presented at the symposium. OGRS is a meeting dedicated to exchanging ideas in and results from the development and use of open source geospatial software in both research and education.  The symposium offers several opportunities for discussing, learning, and presenting results, principles, methods and practices while supporting a primary theme: how to carry out research and educate academic students using, contributing to, and launching open source geospatial initiatives. Participating in open source initiatives can potentially boost innovation as a value creating process requiring joint collaborations between academia, foundations, associations, developer communities and industry. Additionally, open source software can improve the efficiency and impact of university education by introducing open and freely usable tools and research results to students, and encouraging them to get involved in projects. This may eventually lead to new community projects and businesses. The symposium contributes to the validation of the open source model in research and education in geoinformatics

NATIONAL INNOVATION SYSTEM AND MACROECONOMIC POLICIES: BRAZIL AND INDIA IN COMPARATIVE PERSPECTIVE

Efforts towards economic development in Brazil and India share some common aspects. From the beginning of the 1950s to the end of the 1980s, both countries adopted import substitution policies including high tariffs and non-tariff barriers. Since the beginning of the 1990s, liberalizing economic reforms have been implemented by the respective Governments. If we compare the reach of the Brazilian reform to that of India, one could easily conclude that the former was more extensive and profound than the latter; and in conventional indicators of innovative effort such as research and development expenditures, education coverage, average years of education and literacy rate, Brazil’s results are a little bit better than those of India. However, since the beginning of the 1980s, India has been showing better general economic performance than Brazil. This paper argues and gives some empirical evidence to show that India’s performance is explained by its institutional capacity for coordinating conventional macroeconomic policies with other policies related to its National Innovation System.

Digital 3D Technologies for Humanities Research and Education: An Overview

Digital 3D modelling and visualization technologies have been widely applied to support research in the humanities since the 1980s. Since technological backgrounds, project opportunities, and methodological considerations for application are widely discussed in the literature, one of the next tasks is to validate these techniques within a wider scientific community and establish them in the culture of academic disciplines. This article resulted from a postdoctoral thesis and is intended to provide a comprehensive overview on the use of digital 3D technologies in the humanities with regards to (1) scenarios, user communities, and epistemic challenges; (2) technologies, UX design, and workflows; and (3) framework conditions as legislation, infrastructures, and teaching programs. Although the results are of relevance for 3D modelling in all humanities disciplines, the focus of our studies is on modelling of past architectural and cultural landscape objects via interpretative 3D reconstruction methods

Abschlussbericht für die Jahre 1996 - 2007 mit Berichtsband für die Jahre 2005 - 2007 [mit CD]

Sonderforschungsbereich 461 "Starkbeben : Von geowissenschaftlichen Grundlagen zu Ingenieurmaßnahmen" von Juli 1996 bis Dezember 2007 an der Universität Karlsruhe. Forschungsfeld des SFB 461 waren Starkbeben mit einem regionalen Fokus auf den Vrancea-Ereignissen in Rumänien, wo sie immer wieder starke Schäden verursachten. Diese Risiken und die Gewissheit, dass Rumänien und seine Städte wieder von einem Starkbeben betroffen werden, bildeten die Motivation der Arbeit, erkennend, dass Schadensminderung mit moderner Wissenschaft und Technik sowie mit konsequenter Implementierung des Wissens möglich und aussichtsreich ist

Software Process Modeling with Eclipse Process Framework

The software development industry is constantly evolving. The rise of the agile methodologies in the late 1990s, and new development tools and technologies require growing attention for everybody working within this industry. The organizations have, however, had a mixture of various processes and different process languages since a standard software development process language has not been available. A promising process meta-model called Software & Systems Process Engineering Meta- Model (SPEM) 2.0 has been released recently. This is applied by tools such as Eclipse Process Framework Composer, which is designed for implementing and maintaining processes and method content. Its aim is to support a broad variety of project types and development styles. This thesis presents the concepts of software processes, models, traditional and agile approaches, method engineering, and software process improvement. Some of the most well-known methodologies (RUP, OpenUP, OpenMethod, XP and Scrum) are also introduced with a comparison provided between them. The main focus is on the Eclipse Process Framework and SPEM 2.0, their capabilities, usage and modeling. As a proof of concept, I present a case study of modeling OpenMethod with EPF Composer and SPEM 2.0. The results show that the new meta-model and tool have made it possible to easily manage method content, publish versions with customized content, and connect project tools (such as MS Project) with the process content. The software process modeling also acts as a process improvement activity.Ohjelmistoprosessin mallinnus Eclipse Process Frameworkilla ja SPEM 2.0 metamallilla Ohjelmistot ja ohjelmistoteollisuus kehittyvät jatkuvasti. Ketterien menetelmien tulo 1990-luvun loppupuolella, uudet kehitystyökalut ja teknologiat vaativat yhä enemmän huomiota alalla työskenteleviltä ihmisiltä. Organisaatioilla on kuitenkin ollut sekalainen kirjo prosesseja ja erilaisia prosessikuvauskieliä, koska standardia kuvauskieltä ei ole ollut saatavilla. Prosessimetamalli SPEM 2.0 julkaistiin hiljattain. Tätä mallia hyödyntää mm. Eclipse Process Framework Composer (EPFC) –työkalu, joka on suunniteltu prosessien ja menetelmäsisällön kehittämiseen ja ylläpitoon. Työkalun tavoitteena on tukea useita erilaisia projektityyppejä ja kehitystyylejä. Tässä työssä esitellään seuraavat aiheet ja käsitteet: ohjelmistoprosessit, mallit, perinteiset ja ketterät lähestymistavat, metoditekniikkaa sekä prosessien kehittäminen. Lisäksi tutustutaan muutamiin tunnetuimmista metodologioista (RUP, OpenUP, OpenMethod, XP ja Scrum) ja vertaillaan näitä. Työssä tutkitaan tarkemmin Eclipse Process Framework Composer –työkalua, SPEM 2.0 metamallia, näiden ominaisuuksia, käyttöä sekä mallintamista. Esitän tutkimustulokset ja tutkimuksenkulun OpenMethodin mallintamisesta EPFC –työkalulla sekä SPEM 2.0 -metamallilla. Tulokset osoittavat, että uusi metamalli ja työkalu helpottavat prosessin ja menetelmäsisällön hallintaa, mahdollistavat räätälöityjen julkaisujen teon sisällöstä, sekä yhdistävät prosessin projektityökaluihin kuten MS Projectiin. Mallinnus voidaan lisäksi ymmärtää osana prosessin kehittämistä.Siirretty Doriast

A Systematic Literature Review on Cyberbullying in Social Media: Taxonomy, Detection Approaches, Datasets, And Future Research Directions

In the area of Natural Language Processing, sentiment analysis, also called opinion mining, aims to extract human thoughts, beliefs, and perceptions from unstructured texts. In the light of social media's rapid growth and the influx of individual comments, reviews and feedback, it has evolved as an attractive, challenging research area. It is one of the most common problems in social media to find toxic textual content.  Anonymity and concealment of identity are common on the Internet for people coming from a wide range of diversity of cultures and beliefs. Having freedom of speech, anonymity, and inadequate social media regulations make cyber toxic environment and cyberbullying significant issues, which require a system of automatic detection and prevention. As far as this is concerned, diverse research is taking place based on different approaches and languages, but a comprehensive analysis to examine them from all angles is lacking. This systematic literature review is therefore conducted with the aim of surveying the research and studies done to date on classification of  cyberbullying based in textual modality by the research community. It states the definition, , taxonomy, properties, outcome of cyberbullying, roles in cyberbullying  along with other forms of bullying and different offensive behavior in social media. This article also shows the latest popular benchmark datasets on cyberbullying, along with their number of classes (Binary/Multiple), reviewing the state-of-the-art methods to detect cyberbullying and abusive content on social media and discuss the factors that drive offenders to indulge in offensive activity, preventive actions to avoid online toxicity, and various cyber laws in different countries. Finally, we identify and discuss the challenges, solutions, additionally future research directions that serve as a reference to overcome cyberbullying in social media
