Towards a Data Warehouse Contextualized with Web Opinions
October 22-October 24
ISBN: 978-0-7695-3395-7
In this work we consider the web forums where the users give their opinion about the products or services that some organizations offer. The OLAP tools of the traditional data warehouse systems, mainly designed to analyse structured data, cannot be directly applied to take advantage of these on-line text documents. This paper describes the objectives of our new project on so-called contextualized warehouses to exploit these opinion documents. In the analysis cubes of a contextualized warehouse, each fact is linked to a document list. These documents provide information related to the fact (i.e., they describe its context). The opinions in the web posts are typically expressed as small text fragments that sometimes include incomplete sentences. In this paper, we propose to extend the contextualized warehouse infrastructure with new opinion retrieval techniques conceived to classify and search for opinions in document collections with these characteristics. Since the project is still in its early stages, the paper mainly studies the requirements, reviews the main technologies that will be involved in the development of the project and discusses our current/future work.
