If you are interested in the mechanisms behind appaazar and our recommender system, we would like to call your attention the 2nd Workshop on Context-aware Recommender Systems that will take place at the 4th ACM Conference on Recommender Systems. We will present a paper there about the design space of context-aware recommender systems that suggest mobile applications. If you are interested, please drop us a mail to receive a copy. The abstract is as follows.

Abstract: Current technology development in mobile computing and upcoming application stores enable an easy development and distribution of mobile applications. This leads to an increasing number of available applications and to the user’s problem of content discovery. Recommender systems aim at guiding users to relevant items. Currently, recommender systems for mobile applications neglect that the usage of mobile devices is characterized by perpetual changes of a user’s context. In this paper, we give rise to the context-aware recommendation of mobile applications. We explore the design space of recommender systems for mobile applications and describe the different dimensions and techniques for capturing the users, the items, the contexts and the corresponding relevances. For proof of concept we present the prototype of a recommender system that combines the design options in a hitherto unexplored way.

You will find the approach described in the paper and some other ideas that came up and have been reported to us in the last weeks within the next version of appazaar. It will mainly improve our recommender system and fix some bugs of the Android app.
