In this work we build the first BI-RADS parser for Portuguese free texts, modeled after existing approaches to extract BI-RADS features from English medical records. Our concept finder uses a semantic grammar based on the BI-RADS lexicon and on iterative transferred expert knowledge. We compare the performance of our algorithm to manual annotation by a specialist in mammography. Our results show that our parser's performance is comparable to the manual method.

In recent years there is a rapid increase of traffic to a given web server within a short time as the number of Internet users increases, and such a phenomenon is called a flash crowd. Once flash crowds occur in the web server, a response rate decreases or the web server may crash as the load increases. We propose a load reduction system, which prevents excessive accesses and stably delivers content without enhancing the performance of the web server even when flash crowds occur. In the proposed system, a proxy server detects flash crowds by monitoring the number of requests and changes a content delivery system. To limit accesses to the web server, the proxy server redirects a request to another client that holds the content in the cache when flash crowds occur. We also propose a content delivery system that uses a tree construction to reduce the client load. Moreover, its efficacy is shown through simulations.

Knowledge management is becoming one of key success factors for organizations in global economic environment. Knowledge management in the scope of computer science is widely understood as a process that supports and facilitates knowledge creation, access, modification and reuse. In the scope of this paper we investigate different approaches for deploying knowledge management. We are especially oriented towards mid-sized organizations with limited budget and limited resources with knowledge engineering capabilities. We propose an ontology based knowledge management system and present the core architecture as well as a development method for such a system.
This paper considers the estimation of reliability and availability of intrusion-tolerant systems subject to non-detectable intrusions. Our motivation comes from the observation that typical techniques of intrusion to...
