Generation Challenge Program : Follow-Up on Executive Council and Science Council Inquiries

This report was prepared for the autumn 2004 meetings of ExCo and the Science Council. It was later discussed during the CGIAR Business Meeting at AGM 2004. The report is a detailed response to inquiries made by the Executive Council and the Science Council regarding the challenge program's goals and added values

Generation Brexit officially launches in six new languages

Today Generation Brexit officially launches in six new languages - German, French, Italian, Spanish, Polish and Greek. With our new language sections, the Generation Brexit project becomes the only pan-European Brexit project of its type. We want to hear from YOU, in your language. After you set up an account (top right side of the page), you can either come ..

Temporal uncertainty in raw data can impede the inference of temporal and causal relationships between events and compromise the output of data-to-text NLG systems. In this paper, we introduce a framework to reason with and represent temporal uncertainty from the raw data to the generated text, in order to provide a faithful picture to the user of a particular situation. The model is grounded in experimental data from multiple languages, shedding light on the generality of the approach.peer-reviewe

SimpleNLG : a realisation engine for practical applications

This paper describes SimpleNLG, a realisation engine for English which aims to provide simple and robust interfaces to generate syntactic structures and linearise them. The library is also flexible in allowing the use of mixed (canned and noncanned) representations.peer-reviewe

Trashing IMSI catchers in mobile networks

We address the decades-old privacy problem of disclosure of the permanent subscriber identity (IMSI) that makes IMSI catchers a real threat to all generations of mobile networks. A number of possible modifications to existing protocols have been proposed to address the problem; however, most require significant changes to existing deployed infrastructures. We propose a novel authentication approach for 3G and 4G systems that does not affect intermediate entities, notably the serving network and mobile equipment. It prevents disclosure of the subscriber's IMSI by using a dynamic pseudo-IMSI that is only identifiable by the home network for the USIM. A major challenge in using dynamic pseudo-IMSIs is possible loss of identity synchronisation between USIM and home network, an issue that has not been adequately addressed in previous work. We present an approach for identity recovery to be used in the event of pseudo-IMSI desynchronisation. The scheme requires changes to the home network and the USIM, but not to the serving network, mobile phone or other internal network protocols, enabling simple, transparent and evolutionary migration. We provide a detailed analysis of the scheme, and verify its correctness and security properties using ProVerif
