Blogosphere is the collective term encompassing all blogs as a community or social network. According to David Sifry of Technorati, over 57 million blogs were being tracked by Technorati in October 2006; on average, a new weblog is created every second [19]. Because of the huge volume of existing blog posts and their free format nature, the information in the blogosphere is rather random and chaotic; effective access and retrieval techniques are needed to improve the searching quality. The business world has experienced significant influence by the blogosphere.

This paper proposes a new fuzzy time-series model for promoting the stock price forecasting, which provides two refined approaches, a frequencyweighted method, and the concept of Fibonacci sequence in forecasting processes.

The next part of the equation calculates the entropy value for the ratio of interesting documents to documents which contain the term, scaled by the ratio of documents which contain the term. The last part of the equation calculates the entropy value for the ratio of uninteresting documents to documents which contain the term, scaled by the ratio of documents which don’t contain the term. 20 C.
