JAZBEC, MATIC (author), Lavbič, Dejan (mentor)

Svetovni splet je v zadnjih letih postal eden najbolj priljubljenih medijev, preko katerega se podjetja predstavljajo in oglašujejo svoje izdelke ali storitve. Spletna predstavitev lahko prinese odločilno konkurenčno prednost, zato je pomembno, da je le-ta karseda kakovostna. Načinov za predstavitev je na spletu mnogo, od posameznih podjetij pa je odvisno, katere bodo uporabili in kako. Nekatera podjetja se odločijo za predstavitev na enem izmed spletnih portalov, specializiranih za povezavo med kupci in ponudniki storitev ali izdelkov, nekatera držijo stik s strankami preko socialnih omrežij, spet tretja postavijo svoje spletne portale in porabnikom ponudijo edinstveno izkušnjo ob stiku s podjetjem. Namen diplomske naloge je razvoj spletnega pajka, ki pridobi informacije s spletnih strani slovenskih podjetij in njihovih profilov na socialnih omrežjih, ter na omenjenih podatkih ovrednoti različne dimenzije kakovosti informacij. Rešitev je izdelana kot konzolna .NET aplikacija, ki uporablja knjižnice za pridobivanje spletnih vsebin z zahtevki HTTP in njihovo razčlenjevanje s tehnologijami, kot sta xPath in LINQ. Za shranjevanje podatkov je uporabljen strežnik Microsoft SQL Server. Na podlagi izmerjenih karakteristik spletnih strani je bila opravljena statistična analiza, kjer se izkaže, da se vrednosti atributov dimenzij kakovosti med slovenskimi podjetji statistično značilno razlikujejo glede na velikost podjetja in dejavnost, ki jo opravljajo.

• Title: Information quality dimensions analysis of Slovenian companies' websites

Abstract

Over the last decade the World Wide Web became the most popular media through which the companies introduce themselves and advertise their products or services. Web presentation can bring about the crucial competitive advantage, therefore, it is imperative that it is of the highest quality possible. There are various ways of presenting oneself on the internet and it depends on the individual companies which approach they will take. Some companies decide on the website portals' advertising specialized in the connection between the customer and provider of the service or product, others keep in contact with their clients via social media, and some create their own website portals and oer their users a unique contact experience. The purpose of this thesis is to develop a web crawler that would collect information from the websites of Slovenian companies and their proles on social networks and apply a model for evaluating the quality of information. The solution is implemented as a .NET console application that uses HTTP client to obtain web content and query languages such as xPath and LINQ, to extract the relevant data. Extracted data is stored in Microsoft SQL Server. Statistical analysis is then conducted to identify the relations between measured features and join them into common information quality dimensions. It turns out that we can nd and explain the variance in information quality among the websites of Slovenian companies based on their size and business type.
