Organizations require mechanisms to efficiently distribute knowledge such as news releases, seminar announcements, and memos. While the machinery for information storage, manipulation. and retrieval exists, research dealing directly with knowledge distribution in an organizntiunal context is scarce. In this paper, we address this need by first examining the pros and cons of the conventional "ma...

This paper studies the implications for the long-run world income distribution (WID) of two possible knowledge spillovers structures: appropriate technology and backward knowledge spillovers. In an appropriate technology framework, where total factor intensity is an index of the technological level of an economy, countries will grab useful knowledge only from their technological neighborhood, t...

Knowing the correct distribution of senses within a corpus can potentially boost the performance of Word Sense Disambiguation (WSD) systems by many points. We present two fully automatic and language-independent methods for computing the distribution of senses given a raw corpus of sentences. Intrinsic and extrinsic evaluations show that our methods outperform the current state of the art in se...

Since Logic Programming (LP) and Description Logics (DLs) are based on different assumptions (the closed and the open world assumption, respectively), combining them provides higher expressiveness in applications that require both assumptions. Several proposals have been made to combine LP and DLs. An especially successful line of research is the one based on Lifschitz’s logic of Minimal Knowle...

KNOWLEDGE by ASMITA RAHMAN (Under the Direction of Ismailcem Budak Arpinar) ABSTRACT In the fast growing world of information, the amount of medical knowledge is growing at an exponential level. It has now become a very difficult task for a regular person to keep up with all the new discoveries and updates in this domain. This thesis describes an approach to semantically retrieve and distribute...

A telecommunication or computer network today consist of a number of network elements (NEs) manufactured by different vendors. NEs differ significantly since classes if elements are tailored to provide specific services. Interconnecting networks is important for network providers to make them capable of offering the required level of service to their users/customers. The total number of NEs com...

Background knowledge is an important factor in privacy preserving data publishing. Distribution-based background knowledge is one of the well studied background knowledge. However, to the best of our knowledge, there is no existing work considering the distribution-based background knowledge in the worst case scenario, by which we mean that the adversary has accurate knowledge about the distrib...

The management of multimedia documents, which includes storage, indexing, query optimization, and distribution, requires very strong frameworks and policies in order to ensure its efficiency and reliability. There has been much work done in the fields of databases, information retrieval, relevance evaluation, and transaction processing for any kind of data; but these four domains are too often ...

Matching information requirements with available information is an important problem for large organizations. The most commonly used mechanisms to match users and information are information retrieval techniques and information filtering techniques. Information retrieval techniques proposed in literature focus primarily on modeling the content and do not personalize the results to the user. Inf...

Product piracy poses an existential threat to many companies. Juristic property rights, which are currently dominantly put to practice, do not suffice to combat this threat. The rise in cases of piracy and the increasing professionalism of the counterfeiter, give grounds for effective methods of prevention. Based on the gap of existing approaches identified we evaluate how knowledge modeling co...
