The History of IDF and its Influences on IR and Other Fields

The History of IDF and its Influences on IR and Other Fields

The surprisingly simple IDF measure developed in 1972 by Karen Sparck Jones has continued to dominate the term weighting metrics used in information retrieval, despite several efforts to develop more complex measures of term distribution. It has been

Electromagnetic Signatures of WLAN Cards and Network Security

Electromagnetic Signatures of WLAN Cards and Network Security

The proliferation of wireless devices and the availability of new wireless applications and services raise new privacy and security concerns. Although network-layer anonymity protects the identities of the communication endpoints, the physical layer of

Electromagnetic Signatures of Wireless Local Area Network Cards: Implementation Issues and Detection in the Presence of Interferers

This work investigates a measurement method for detecting the radio-frequency electromagnetic characteristics of an individual 802.11b wireless local-area network (WLAN) card--its electromagnetic signature--in the presence of an interfering signal. The

The Role of Semantic Roles in Disambiguating Verb Senses

The Role of Semantic Roles in Disambiguating Verb Senses

We describe an automatic Word Sense Disambiguation (WSD) system that disambiguates verb senses using syntactic and semantic features that encode information about predicate arguments and semantic classes. Our system performs better than the best published

HL7 Experimental Registry

HL7 Experimental Registry

Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that
