NLP applications in all domains require more than a formal grammar to process the input in a practical way, because natural language contains phenomena that a formal grammar is usually not able to describe. Such phenomena are typically disfluencies and ext ...
Grammar-based compression means to find a small grammar that generates a given object. Such a grammar reveals the structure of the object (according to the grammar formalism used); the main advantage of this compression method is that the resulting grammar ...
Electrochromic displays based on porous nanostructured films, "elec.-paint displays", are promising for electronic-paper applications due to their prominent paint-on-paper qualities. The authors investigated the charge-discharge kinetics of elec.-paint dis ...
We show that the finite-length scaling parameters for irregular LDPC codes when used over the binary erasure channel can be computed without resorting to ``covariance evolution''. We provide simple expressions that can be evaluated using solely the degree ...
The expression problem is fundamental for the development of extensible software. Many (partial) solutions to this important problem have been proposed in the past. None of these approaches solves the problem of using different, independent extensions jo ...
We discuss the limitations of conventional closed loop power control (CLPC). We derive a closed-form expression for the control error. We then propose two algorithms that reduce this error. Simulations show a reduced power error compared to current CLPC te ...
For-comprehensions, an operator to apply expressions on selected elements of sets or lists, can replace most of SQL as a query language. I present my current and future work on integrating for-comprehensions for database access in general-purpose programmi ...
This document gives information on parsing experiments applied to the standard Wall Street Journal corpus (``Standard'' means that this corpus has been widely used for exhibiting parsing tests of various models). The tested syntactic models are : standard ...
Pattern matching combined with regular expressions has many applications including text and XML processing, lexical analysis, classification of DNA segments and content-based routing. Patterns contain variables to refer to parts of the matching input. But ...
This thesis is at the crossroad between Natural Language Processing (NLP) and digital circuit design. It aims at delivering a custom hardware coprocessor for accelerating natural language parsing. The coprocessor has to parse real-life natural language and ...
