"More and more companies are discovering the possibilities that social media sites such as Facebook and YouTube hold for maintaining a conversation with their customers, as well as keeping their brand(s) top-of-mind for the consumer in an extremely cost-effective way. The PR 2.0 proposal addresses the need for European SMEs to take advantage of the benefits of using social media to increase their competitiveness by offering an affordable, cost-effective centralised web tool for management of marketing campaigns using popular social media tools such as social networks and microblogging platforms. In addition, PR 2.0 will allow companies large and small to easily monitor user-generated content about their business or brands, allowing them to easily manage their online reputation, be alerted to possible public relations crises and take immediate actions. A cloud computing model for the exploitation of the project results will ensure that the PR2.0 project is accessible to SMEs and a user-centered user interface will ensure that the system is in line with their skill set and needs. Opinion Mining techniques and advanced web design and development methodologies and a user-centered design perspective will be used in this project with the aim of achieving the objective of developing a novel tool in a fast-paced, ever changing environment like social media and with a potential impact not only in the PR and marketing sector but in almost any business activity. The commercialisation of the PR2.0 tool will result in economic benefits for the consortium, savings and improvement of competitiveness for the PR 2.0 users, and, by the generation of training material and guidelines, the PR2.0 will also educate on and encourage the use of Web 2.0 tools among the European SMEs."
