Abstract
Število mobilnih aplikacij se je v zadnjem času izredno povečalo. V največji trgovini z aplikacijami za mobilni operacijski sistem AndroidTM Google Play je število aplikacij že preseglo dva milijona. V tako veliki množici se aplikacije težko prebijejo v ospredje, saj je vidnost posamezne aplikacije majhna. Zato ni presenetljivo, da ima večina aplikacij zelo majhno število prenosov oz. uporabnikov. Za pridobivanje novih uporabnikov je (med drugim) pomembna vidnost aplikacije na lestvicah najbolj priljubljenih aplikacij. Zato je eden od ciljev razvijalcev aplikacij uvrstitev svoje na lestvice najbolj priljubljenih. Osnovni cilj magistrskega dela je bil ugotoviti, katere tehnične (velikost in dovoljenja) in druge (ocena, število ocen, število dni od zadnje posodobitve ...) značilnosti aplikacij pomembno vplivajo na njihovo uspešnost. Uspešnost določimo z uporabo treh meril: mesta aplikacije na lestvici najbolj priljubljenih, števila prenosov ter podane ocene uporabnikov. Za dosego tega cilja smo zajeli in analizirali podatke o najbolj priljubljenih aplikacijah na Google Playu glede na tri tipe aplikacij (Aplikacije, Igre in Družina). Tipe aplikacij smo proučevali še podrobneje glede na to, ali so brezplačne, plačljive, nove brezplačne ter nove plačljive. Tako smo dobili 12 skupin aplikacij, ki smo jih poimenovali zvrsti. Lestvice najbolj priljubljenih aplikacij smo proučevali na primeru države ZDA, ki je največji in najzanimivejši trg. Podatke smo zajeli s pomočjo spletnega luščilca podatkov. Nad zbranimi podatki smo izvedli statistične teste, s katerimi smo ugotovili vpliv tehničnih in drugih značilnosti aplikacij na njihovo uspešnost za vsako zvrst posebej. Izkazalo se je, da se posamezne zvrsti aplikacij po eni strani razlikujejo med seboj glede vpliva nekaterih značilnosti na merila uspešnosti, po drugi strani pa smo zaznali tudi nekaj lastnosti, ki bolj ali manj veljajo za vse zvrsti. Tako se večja velikost pri večini zvrsti ni pokazala kot izrazito negativna značilnost, kot je tipično izpostavljena na straneh za razvijalce. Aplikacije, ki so posodobljene v zadnjem času in niso nove, so na splošno više na lestvici in imajo boljšo oceno od drugih. Aplikacije z večjim številom ocen so prav tako više na lestvici, imajo pa tudi večje število prenosov in pri večini zvrsti boljšo oceno. Aplikacije više na lestvici in z večjim številom prenosov večinoma uporabljajo več dovoljenj, kar pomeni tudi, da ponujajo več funkcionalnosti. Čeprav Google priporoča omejevanje števila dovoljenj, se to ni izkazalo za ključno, ampak je, kot kaže, pomembnejše število podprtih funkcionalnosti.

Title:
Evaluating the impact of technical and other characteristics of mobile applications on their performance
Abstract:
In recent years the number of mobile applications has increased considerably. For instance the number of applications in the largest app store for AndroidTM mobile operating system - Google Play has exceeded two millions. As the visibility of individual applications is low it is not surprising that the majority of applications have only a very small number of downloads or users. One of the important factors in attracting new users is application’s visibility on the charts of the most popular applications (top charts). Therefore, one of the objectives of the application developers it to position their applications on the top charts. The main goal of the master thesis was to determine what technical (size and permissions) and other (user ratings, number of ratings, the number of days since the last update, number of screenshots ...) characteristics of the applications have a significant impact on their performance. Performance is determined by using the three criteria: the position of application on the top charts, the number of the application downloads and user ratings of the application. To achieve this goal we captured and analysed data of the most popular apps on Google Play in the three main types (Applications, Games and Family). We studied these categories in further detail considering whether the applications are free, paid, new free and new paid. All together we got 12 different groups of applications that we name genres. United states top charts were selected for the study as they represent the largest and most interesting market. The data was collected by using web scrapper. Statistical tests were performed on the collected data separately for each genre to determine the impact of technical and other characteristics of the applications on their performance. The results showed both similarities and differences between genres. While some characteristics are specific only for certain genres, others are valid for all or most genres. For instance, larger size of applications in contrast to assertions of many developer web pages did not prove to be a very negative feature. Applications that have been updated recently and are not new, are generally higher on the charts and have higher user ratings than others. Applications with a large number of user ratings are also higher on the chart, have larger number of downloads and in most genres a higher user ratings. Most apps that are higher on the chart and have a higher number of downloads use more permissions. Consequentially this means that they also offer more functionality. Despite the fact Google recommends limiting the number of permissions this does not seem to be a decisive factor especially in comparison to the number of supported functionalities.
