Denna rapport beskriver utvecklingen av en Instant Messaging klient som implementerats som en språkwrapper. Klienten använder ett känt öppen källkods-bibliotek vid namn libGaim för att få tillgång till Instant Messaging tjänster. Klienten fungerar som en språkwrapper till detta bibliotek, och låter andra applikationer nyttja biblioteket genom ett databasgränssnitt. Arbetet har utförts åt och hos Evolve i Karlstad. Systemet som utvecklats klarar att hantera vanliga Instant Messaging-funktioner så som uppkoppling av konto, nedkoppling, ändring av status, visa kompisikoner, och hämtning av information angående kompisar. I beskrivandet av arbetet med detta system ges bakgrundsinformation angående wrappers och Instant Messaging, och dessutom angående de verktyg och metoder som använts likt byggverktyget SCons och utvecklingsmetoden eXtreme Programming. Valet av lösning och design presenteras. Som en del av arbetet undersöks språkwrappers med hjälp av av ett antal tester. Dessa tester visade på vilka skillnader som kan väntas beroende på valet av språkwrapper. En språkgenerisk språkwrapper (som skapar ett gränssnitt mot flera språk) behöver inte utgöra någon större prestandaoverhead jämfört med en språkstatisk språkwrapper (som skapar ett gränssnitt mot ett språk). Resultatet av arbetet blev ett system som Evolve blev nöjda med och som uppfyllde alla krav som ställdes, antingen fullständigt eller delvis. / This report describes the development of an Instant Messaging client that is implemented as a language wrapper. The client uses a well known open source library, known as libGaim, to access Instant Messaging services. The client works as a language wrapper for this library, and allows other applications to use the library by means of a database interface. The work has been carried out at and for Evolve in Karlstad. The system that has been developed can handle common Instant Messaging operations such as connecting a user account, disconnecting, changing an accounts status, showing buddy icons, and collecting information regarding buddies. In the description of the work with this system, background information is given regarding wrappers and Instant Messaging, and also regarding the tools and methods used, such as the build tool SCons and the development method eXtreme Programming. The choice of solution and design is presented. As a part of the work, language wrappers are evaluated using a number of tests. These tests show the differences that can be expected depending on the choice of language wrapper. A language generic language wrapper (which creates an interface for several languages) need not imply any significant performance overhead compared to a language static language wrapper (which creates an interface towards one language). The result of the work we have done was a system that Evolve was pleased with and that satisfies all the requirements, either completely or partially.

Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits from new services. With the rapidly growing trend toward LBS, there is a need for standard LBS protocols. This thesis started with introducing the Internet Engineering Task Force GEOPRIV working group, which endeavors to provide standard LBS protocols capable of transferring geographic location information for diverse location-aware applications. Through careful observation, it was found that Session Initiation Protocol (SIP) is well suited to the GEOPRIV requirements. The aim of this research was therefore to explore the possibility of the integration of LBS and the SIP protocol and, to some extent fulfill the GEOPRIV requirements.

The introduction of the Internet and computers into the work environment have changed the news industry. New models of revenues for spreading the news, and the reachability and accessibility of the news has grown tremendously. These implications have influenced the way media company’s employees have to work, from multi-skilling to communicating with each other efficiently. This research seeks to investigate the current state of the internal communication flow in a Swedish media company called Hallpressen AB and to find opportunities for improving the internal communication flow inside the company. In order to fully understand the existing situation in the company, the authors observed nine of the company’s departments, held 14 interviews with managers and executive committee members, and conducted two focus groups. Based on the data collection, the authors created a communication channel model of the existing communication inside the media company, and performed a qualitative content analysis to summarize the findings from the observations and interviews. The focus groups were performed in order to examine an existing communication tool called “Slack”, and to understand the general perception that the company’s employees held of it. From the findings, the authors suggested possible improvements for the company’s internal communication flows. First, what could be improved in the management of communication inside the company, such as opening of a communication department or hiring an internal communicator. Second, what could be improved in already existing communication channels, such as creation of special part on the intranet for every department and etc.

<p>There are few empirical studies about instant messaging, and the measurements used are somewhat diverse. The main purpose of this study was to investigate if depression and loneliness differed in relation to instant message habits among young adolescents. Special focus was also on motivation behind, and time spent on instantmessaging. The study was conducted using a self report questionnaire,using 3 factors for motivation and 8 items to measure time. The 365 participants were between ages 12 and 16. The study found that depression and loneliness differed in many ways depending on what measurement compared with. The conclusion drawn is that future studies have to use more precise measurements.</p> / <p>Det finns få empiriska studier om chattande och de mått som används varierar.

Studien genomfördes med ensjälvrapports frågeformulär och använde tre faktorer för motivation och 8 <em>items </em>för att mäta tid. De 365 deltagarna var mellan åldrarna 12till 16. Studien fann att depression och ensamhet skiljde sig på mångasätt beroende på vad för mått man jämförde med. Slutsatsen som drasär att framtida studier måste använda mer precisa mått.</p>

Currently SMS is the most popular one for text messaging market, and the traffic of SMS was 5.9 trillion messages in 2011 which occupies 64.1% of the global text market. According to the research from Informa, the market share of SMS will down to 42.1% in 2016. At the same time, global mobile instant messaging traffic will increase from 1.6 trillion messages in 2011 to 7.7 trillion messages in 2016, doubling its share of global messaging traffic from 17.1% in 2011 to 34.6% in 2016. The number of IM users in 2011 reaches 2.6 billion and there are various kinds of instant messaging application available in market already. Each IM application tries to focus on the different features to differentiate from other competitors. Some IM applications are focusing on the computer users like MSN or Skype and others are focusing on the mobile device users like Whatsapp or Line. ChatInn provides a new way to help people to keep communication between different platforms. Whatsapp, one of the major competitors of IM service provider, after reaching 1m users by the end of 2009, Whatsapp’s downloads increased tenfold during 2010. The company does not reveal its current user numbers but analysts assume it is in the tens of millions. ChatInn is a web base instant messaging service which can work on the computers and the mobile devices. ChatInn’s goal is to provide a quick, simple and a safe way for person who wants a quick short meeting or chatting. Not like other IM applications, ChatInn doesn’t require the installation or the complicated registration to be able to use this service. For the new user, the only required information is the username and password, no other personal information is needed. To host or start a short meeting or chatting, the user only needs to send out the meeting url link which is generated by ChatInn to the target contact. The target contact could just simply click on the link from the computer or mobile device to enter the meeting or chatting. ChatInn also provides the app for mobile device users which allow the user could be always contacted online just like other IM apps. ChatInn is expected to reach 100K users in 6 months and more than 1 million users in the 3rd year of operation. Advertising will be the major profit center, and it highly depends on the size of user base. There will be net profit in the end of 2nd year and will generate net profit of 5.29M. When the active users keep growing steadily, ChatInn would start global marketing promotion as well in order to keep expending the business scale.

Nowadays, the internet is an unseperatable part of human life and instant messaging software becomes an important role of communication channel. There are 40 million global IM registration popularity who use IM and billions of messages are sent everyday. In Taiwan, there are 6.5 million registration popularity and IM is the third important internet appilication, besides WWW and e-mail. As IM has become more and more important, there was few academic researchs published. We investigated consumer IM adoption behavior by focus group interview and structural equation model analysis. After holding a focus group interview, some antecedent of adopting IM was found out. Then we integrated technology acceptance model with media richness, computer self-efficacy and subjective norm as the antecedents of perceived usefulness(PU) and perceived ease of use(PEU) and analysised this structural equation model with LISREL. We found that subjective norm is an antecedent of PU, media richness and computer self-efficacy are PEU¡¦s antecedents. Finally, we made some suggestion for practice and other researchers base on the result.
