Short Time

Fresh information is important for real business. In order to realize fresh information retrieval, we need not only to collect documents in a short time, but also to rank the results in the suitable order. However, conventional ranking methods are not suited for fresh information retrieval because they ignore temporal value of information. So, we have proposed the novel ranking method FTF·IDF for fresh information retrieval. FTF·IDF extends TF·IDF by means of using FTF (Fresh Term Frequency) instead of TF (Term Frequency). FTF differs from TF because FTF decreases as time goes. The speed of decreasing FTF is determined by the dumping factor. The dumping factor is sensitive against small changes of documents. So, we use a threshold to ignore such small changes. In some papers we published, we detect the optimal threshold manually. In this paper, we proposed an adaptive calculating method in order to detect threshold automatically. In this method, the optimal value is determined by iterating to test generated thresholds. In this paper, we describe our method and its evaluation.

In many respects, the least important part of the 1999 elections were the elections themselves. From the beginning of General Abdusalam Abubakar’s transition program in mid-1998, most Nigerians who were not part of the wealthy “political class” of elites—which is to say, most Nigerians— adopted their usual politically savvy perspective of siddon look (sit and look). They waited with cautious optimism to see what sort of new arrangement the military would allow the civilian politicians to struggle over, and what in turn the civilians would offer the public. No one had any illusions that anything but high-stakes bargaining within the military and the political class would determine the structures of power in the civilian government. Elections would influence this process to the extent that the crowd influences a soccer match.
