Unified Financial Portfolio is a financial application that applies concepts of information retrieval and Web 2.0 to provide a better understanding of the market trends taking into account the users information needs. It integrates and retrieves non-structured content related to the financial domain, from social networks, Stock Exchange and newspapers. The main contributions of this work are the software architecture, the content based semantic search model and the use of Big Data technology. The model is based on the vector-space model, including a retrieval weighting algorithm using domain specific considerations. This paper presents the application evaluation, using a large amount of unstructured content from dynamic and social web content sources.
