Welcome to the Questionnaire survey for Service Utilization Ranking

This survey aims to find out what you think of as suitable measures for ranking API's

The Service Utilization Rank (serviut rank) measure is inspired by the PageRank approach for ranking Web pages. Central to the PageRank approach are the incoming links to a page and the PageRank of the source of the links. The Mashups that use a given API are analogous to the incoming links and their rating is analogous to the PageRank of the source of the links. More the number of highly rated Mashups that use a given API, higher is the serviut rank of the API

To compute the serviut rank, we first compute the serviut score for each API. The serviut score of an API depends on the following five factors:

1. The set of mashups that use the API (Ma)
2. The set of mashups in the category (Mc)
3. User assigned popularity of the mashups in Ma (P(Ma)) and Mc (P(Mc))
4. User assigned popularity of the mashups in Mc
5. Popularity of the mashups based on Web traffic

The serviut score has two components. The first component, user popularity score, is the derived using the number of Mashups and their user assigned popularity. The second component, traffic popularity, is derived using the Alexa rankings.

You will be asked five questions and asked to rate how suitable the measure is. When you are ready please press the start button.
