The document discusses a novel collaborative filtering-based web service recommender system aimed at assisting users in selecting optimal web services based on quality-of-service (QoS) and location information. It highlights the challenges posed by the increasing number of available web services and the potential issues that arise from improper selections. The proposed system demonstrates significant improvements in recommendation accuracy through extensive experiments involving over 1.5 million QoS records.

Web Service Recommendation via Exploiting Location
and QoS Information
Abstract
Web services are integrated software components for the support of interoperable machine-to-
machine interaction over a network. Web services have been widely employed for
building service-oriented applications in both industry and academia in recent years. The
number of publicly available Web services is steadily increasing on the Internet. However,
this proliferation makes it hard for a user to select a proper Web service among a large
amount of service candidates. An inappropriate service selection may cause many
problems (e.g., ill-suited performance) to the resulting applications. In this paper, we
propose a novel collaborative filtering-based Web service recommender system to help
users select services with optimal Quality-of-Service (QoS) performance. Our recommender
system employs the location information and QoS values to cluster users and services, and
makes personalized service recommendation for users based on the clustering results.
Compared with existing service recommendation methods, our approach achieves
considerable improvement on the recommendation accuracy. Comprehensive experiments
are conducted involving more than 1.5 million QoS records of real-world Web services to
demonstrate the effectiveness of our approach.
