Notebook paper: TNO instance search submission 2011

The TNO instance search submission to TRECVID 2011 consisted of three different runs: one is using an exhaustive keypoint search, one is using a bag-of-visual-words approach and one is using open-source face-recognition software. Our run approaches: Briefly, what approach or combination of approaches did you test in each of your submitted runs?...

A multi-dimensional model for search intent.

The interaction of users with search engines is part of goal driven behaviour involving an underlying information need. Information needs range from simple lookups to complex long-term desk studies. This paper proposes a new multi-dimensional model for search intent, which can be used for the description of search sessions. Using examples from...

Transparency about net neutrality: A translation of the new European rules into a multi-stakeholder model

The new European framework directive contains a number of policy objectives in the area of net neutrality. In support of these objectives, the universal service directive includes a transparency obligation for ISPs. This paper proposes a multi-stakeholder model for the implementation of this transparency obligation. The model is a multi...

Ethernet Operation Administration and Maintenance ; Opportunities for the NREN community

Ethernet started its life as a Local Area Network technology and initially did not have Operations, Administration and Maintenance (OAM) features like IP Ping, IP Traceroute and SDH Loss of Frame. Monitoring and management was mainly done on the IP level. In the case of delivery of Ethernet connections or services IP OAM traffic could follow a...

Learning to rank for why-question answering

In this paper, we evaluate a number of machine learning techniques for the task of ranking answers to why-questions. We use TF-IDF together with a set of 36 linguistically motivated features that characterize questions and answers. We experiment with a number of machine learning techniques (among which several classifiers and regression...

WebM een alternatief voor H.264?: Onderzoek naar het gebruik van open source software en open standaarden

WebM is een nieuw videoformaat en wordt gepositioneerd als een open en vrij te gebruiken alternatief voor de videostandaard H.264.

A cross-lingual framework for monolingual biomedical information retrieval

An important challenge for biomedical information retrieval (IR) is dealing with the complex, inconsistent and ambiguous biomedical terminology. Frequently, a concept-based representation defined in terms of a domain-specific terminological resource is employed to deal with this challenge. In this paper, we approach the incorporation of a...
