Many organizations and most Internet service providers need to keep the history of web accesses in the form of proxy logs. Such logs would be later used for web usage as well as for investigating abnormal activities including an abuse, a misuse or fraud. This paper classifies web proxy logs into normal, non- burst and burst. To filter out normal logs, we use Apriori algorithm in Weka mining tool to...
Logs are typically used for performing post mortem for abnormal activities. Most Internet service providers keep the history of users' web accesses in terms of proxy logs for investigating a misuse or fraud. However, the majority of the logs represent normal behavior, and no thorough analysis of such logs is usually performed, keeping them on storage would consume very big space. This paper analyzes...
Sentiment analysis is an interesting application in natural language processing, aiming at identifying emotional expressions attached to speeches or texts. In this paper, simple yet effective strategies to extract feature-based segments and combine sentiment scores were studied. The strategies exploit textual structures to improve the segmentation quality. Each relevant set of segmented texts is subsequently...
We present principles for an integrated neuroinformatics framework which makes explicit how models are grounded on empirical evidence, explain (or not) existing empirical results and make testable predictions. The new ontological framework makes explicit how models bring together structural, functional, and related empirical observations. We emphasize schematics of the model’s operation linked to...
