Discard ban and balanced harvest: a contradiction?

Balanced Packet Discard for Improving TCP Performance in ATM Networks

TCP suffers from low performance over Asynchronous Transfer Mode (ATM) networks. This is mainly because during phases of congestion, ATM drops cells without taking into account the effect this has on the upper layer protocols. Two main algorithms, called PPD and EPD, were proposed in the past for improving TCP performance. However, they address one aspect of the problem, that has only small eff...

Contradiction Detection with Contradiction-Specific Word Embedding

Contradiction detection is a task to recognize contradiction relations between a pair of sentences. Despite the effectiveness of traditional context-based word embedding learning algorithms in many natural language processing tasks, such algorithms are not powerful enough for contradiction detection. Contrasting words such as “overfull” and “empty” are mostly mapped into close vectors in such e...

Teleteaching and Teamwork – a Contradiction?

Conjunction and Contradiction

The Law of Non-Contradiction (hereafter: LNC) says that no contradiction can be true. But what is a contradiction? And what does it take for a contradiction to be true? As Patrick Grim [5] has pointed out, a quick look at the literature will reveal a large menagerie of different interpretations of the basic terms and, consequently, of LNC. Grim actually identifies as many as 240 different optio...

A Contradiction Management System

In most existing systems that give expert advice, efforts are made to ensure that the rules in the knowledge base do not give rise to contradictions. This is partly to avoid confusing the user, and partly for fear that a logical system that generates even a single contradiction must collapse. We argue that not only can contradictions be tolerated, but they can even be useful. In a legal context...
