Optical Character Recognition (OCR) attempts to convert large amounts of documents into electronic form for further processing. The most important stage of an OCR system is the feature extraction stage, because the recognition performance depends on the features selected at this stage. In this...

Although the basic protocol of the Next-Generation Internet (NGI) was defined as IPv6 over 10 years ago, the transition from the current IPv4-based Internet to IPv6-based NGI was still a long way to go. With the growth of Internet, it is predicted that IANA will exhaust its IPv4 address pool on 17-...

Typically, a context-aware system is able to collect vast amounts of information coming from data collected by sensors. The problem that occurs lies mainly in how this information can be integrated and used at a semantic level, without a significant reduction in system performance. In the scope of...

The quest for providing tissue characterization and functional mapping during minimally invasive surgery (MIS) has motivated the development of new surgical tools that extend the current functional capabilities of MIS. Miniaturized biophotonic probes can be inserted into the instrument channel of...

This thesis describes the brand new concept of the Prolog Adventure Implementation technique, being a method for the implementation of adventure computer games with the use of Logic Programming (Prolog). An adventure game’s environment is discrete, that is to say the player's character undertakes...

If Information Retrieval (IR) on the web is dominated by systems earning ranking functions from log data, standard ad hoc IR is largely dominated by probabilistic systems with few parameters to set, as Okapi, the language models or the Divergence from Randomness models. These latter models are...

Citizen sensor networks are open information systems in which members of the public act as information providers. The information distributed in such networks ranges from observations of events (e.g. noise measurements or monitoring of environmental parameters) to probabilistic estimates (e.g....

In a seminal paper in 1997 Lin and Reiter introduced the notion of progression for basic action theories in the situation calculus. The idea is to replace the initial knowledge base by a new set of sentences which reflect the changes due to an action. Their definition has the intended properties...

Larry S. Davis' talk will cover recent work on the acquisition and application of contextual models for object and action recognition. For object recognition, I will discuss how fine grained contextual models that capture geometric and topological relations between objects in pictures can lead to...
