Clinical psychologists currently struggle to organize information about patients during a cognitive behavioral therapy (CBT) treatment. During a CBT treatment, the patients will have to fill in paper forms between therapy sessions. These forms contain information about how the patients are feeling and the different tasks that they have been assigned as homework. Some problems with the paper forms are that they can easily be forgotten, lost, destroyed, etc. Before this project, Zeeds App could be used instead of the paper forms but the psychologists could not review the homework results from the app. Our solution to this problem is a web portal that is connected to Zeeds App where psychologists can oversee their patient's homework results. Since psychologists can review the answers to the forms before therapy sessions the sessions can be more focused. / Psykologer har för tillfället problem med att organisera information om deras patienter under en kognitiv beteendeterapi. Under en kognitiv beteendeterapi kommer patienten behöva fylla i pappersformulär mellan möten med sin psykolog. Dessa formulär innehåller information om hur patienterna mår och de olika uppgifter som de har fått att utföra som hemläxa. Några problem med dessa pappersformulär är att de är lätt att glömma bort formulären, tappa bort formulären, eller att formulären blir förstörda osv. Innan det här projektet kunde Zeeds App användas istället för pappersformulären men det fanns ingen möjlighet för psykologer att se resultaten från appen. Våran lösning till det här problemet är en webbportal som är kopplad till Zeeds App där psykologer kan se deras patienters resultat för hemläxan. Eftersom psykologer kan se resultaten från hemläxan innan möten kan mötena bli mer fokuserade.

This thesis is examining the best known internet service -- WWW, it's history and current trends. Following part deals conception of Web 2.0, which is currently subject of intensive discussions it's supporters and opponents. Theoretical knowledge is than applied in analysis of services of new developed web portal koli.cz, which I personally consider the goal of thesis. There are mentioned both of particular sections of web-portal and their interconnection within the whole system. In connection with practical part of thesis are described the most important web portals in world's and Czech Republic's internet market and their biggest source of income, internet advertisement. Own contribution of this thesis is mainly in it's practical part, which is intended to be applied for following analysis and development of koli.cz.

Ontology, an explicit specification of a shared conceptualisation, captures knowledge about a specific domain of interest. The realisation of ontologies, revolutionised the way data stored in relational databases is accessed and manipulated through ontology and database integration. When integrating ontologies with relational databases, several choices exist regarding aspects such as database implementation, ontology language features, and mappings. However, it is unclear which aspects are relevant and when they affect specific choices. This imposes difficulties in deciding which choices to make and their implications on ontology and database integration solutions. Within this study, a decision-making tool that guides users when selecting a technology and developing a solution that integrates ontologies with relational databases is developed. A theory analysis is conducted to determine current status of technologies that integrate ontologies with databases. Furthermore, a theoretical study is conducted to determine important features affecting ontology and database integration, ontology language features, and choices that one needs to make given each technology. Based on the building blocks stated above, an artifact-building approach is used to develop the decision-making tool, and this tool is verified through a proof-of-concept to prove the usefulness thereof. Key terms: Ontology, semantics, relational database, ontology and database integration, mapping, Web information portal. / Information Science / M. Sc. (Information Systems)

Web portals are one of the rapidly growing applications, providing a single interface to access different sources (providers). The results from the providers are typically obtained by each provider querying a database and returning an HTML or XML document. Performance and in particular providing fast response time is one of the critical issues in such applications. Dissatisfaction of users dramatically increases with increasing response time, resulting in abandonment of Web sites, which in turn could result in loss of revenue by the providers and the portal. Caching is one of the key techniques that address the performance of such applications. In this work we focus on improving the performance of portal applications via caching. We discuss the limitations of existing caching solutions in such applications and introduce a caching strategy based on collaboration between the portal and its providers. Providers trace their logs, extract information to identify good candidates for caching and notify the portal. Caching at the portal is decided based on scores calculated by providers and associated with objects. We evaluate the performance of the collaborative caching strategy using simulation data. We show how providers can trace their logs and calculate cache-worthiness scores for their objects and notify the portal. We also address the issue of heterogeneous scoring policies by different providers and introduce mechanisms to regulate caching scores. We also show how portal and providers can synchronize their meta-data in order to minimize the overhead associated with collaboration for caching.

As the change of external environment and internal resources, web portals have transformed their business models from online advertisement model into others, such as electronic commerce model, online game model and short message service model. Different external environment, as well as diverse resources of the main web portals of Taiwan and Mainland China , leads the different transformation process across the Taiwan Strait. Generally, the main web portals in Taiwan like Yahoo! Kimo, PC home and Yam, have chosen online advertisement and electronic commerce model as their main business. On the contrary, Sina, Sohu and NetEase, the main web portals in China, which have transformed their business model into online game and short message service model. This research explores some factors which may influence the transformation of web portals in Taiwan and China, and constructs the internal and external conditions which could successfully transform the web portals to their business models by secondary data analysis and case analysis. There are several factors which influence the web portals to adopt certain business to run their business models.

Vienas iš esminių semantinio tinklo komponentų yra ontologijos. Ontologija yra tam tikros dalykinės srities sąvokų visumos specifikavimas išreikštu pavidalu. Semantiniai interneto portalai naudoja ontologijas kaip žinių bazę. Tačiau ontologijų kūrimas nėra toks paprastas, todėl reikia metodikos, kaip aprašyti dalykinę sritį ontologijų kalba, kad ji būtų realizuojama interneto portale, atitiktų vartotojų poreikius ir ontologijų kokybės kriterijus. Šio magistrinio darbo tikslas yra padidinti semantinių portalų kūrimo galimybes sudarant ir praktiškai išbandant metodiką, pagal kurią portalų kūrėjai galėtų kurti semantinius portalus, panaudodami dalykinės srities ontologiją. Darbe aprašyta ontologija grindžiamo portalo kūrimo metodika, kuri glaudžiai susijusi su dalykinės srities ontologijos sudarymo procesu; panaudotos ontologijos modelio saugojimo reliacinėje duomenų bazėje galimybės, atliktas ontologijos savybių rodiklių skaičiavimas. / Web portals collects the information scattered on the internet and organizes it for easy search and access. Current Web technologies employed to build up these portals present serious limitations regarding information search, access, extraction, interpretation and processing. The Semantic Web provides a common framework that allows data to be shared, reused and processed directly and indirectly by machines. To facilitate this process, OWL have been developed as standard formats for the sharing and integration of data in the form of rich conceptual schemas called ontologies. An ontology defines a common vocabulary for researchers who need to share information in a specific domain. There are several methods for facilitating development of ontologies. Although, neither describes how to build a Semantic Web portals step by step, using the latest Web portals development tools and technologies. The main goal of this work is to propose a development methodology for building Semantic Web portals from the scratch.

The Energy Industry utilizes Energy Management Information Systems (EMIS) smart meters to monitor utility consumers’ energy consumption, communicate energy consumption information to consumers, and to collect a plethora of energy consumption data about consumer usage. The EMIS energy consumption information is typically presented to utility consumers via a smart meter web portal. The hope is that EMIS web portal use will aid utility consumers in managing their energy consumption by helping them make effective decisions regarding their energy usage. However, little research exists that evaluates the effectiveness or success of an EMIS smart meter web portal from a utility consumer perspective. The research goal was to measure EMIS smart meter web portal success based on the DeLone and McLean Information Success Model. The objective of the study was to investigate the success constructs system quality, information quality, service quality, use, and user satisfaction, and determine their contribution to EMIS success, which was measured as net benefits. The research model used in this study employed Structural Equation Modeling (SEM) based on Partial Least Squares (PLS) to determine the validity and reliability of the measurement model and to evaluate the hypothetical relationships in the structural model. The significant validity and reliability measures obtained in this study indicate that the DeLone and McLean Information Success Model (2003) has the potential for use in future EMIS studies. The determinants responsible for explaining the variance in net benefits were EMIS use and user satisfaction. Based on the research findings, several implications and future research are stated and proposed.
