This is the main text of a proposal submitted to the Defense Advanced Research Projects Agency in response to BAA #96-43, " High-Performance Knowledge Bases ". The funded project will run for three years, beginning May 1, 1997 and ending April 30, 2000.

Background and Objectives: Abortion is one of the main causes of maternal mortality. The lack of knowledge of physicians and midwives about the abortion laws can lead to the deficiency of presenting accurate information to pregnant women, and consequently to increase unsafe abortions. The purpose of this study was to assess the relationship of knowledge and attitude towards legal abortion laws ...

Recently, Knowledge Management (KM) has gained incredible attention in business world because of the rising importance of knowledge as a competitive power and strategic resource. However, Small and Medium Size Enterprises (SMEs) have faced some challenges about the employment of Knowledge Management (KM) practices. The principal objective of this study is to explore the regarded challenges of T...

We introduce an adversarial learning framework, which we named KBGAN, to improve the performances of a wide range of existing knowledge graph embedding models. Because knowledge graph datasets typically only contain positive facts, sampling useful negative training examples is a non-trivial task. Replacing the head or tail entity of a fact with a uniformly randomly selected entity is a conventi...

Automated question answering has been a topic of research and development since the earliest AI applications. Computing power has increased since the first such systems were developed, and the general methodology has changed from the use of hand-encoded knowledge bases about simple domains to the use of text collections as the main knowledge source over more complex domains. Still, many researc...
