Scalable syntactic processing will underpin the sophisticated language technology needed for next generation information access. Companies are already using nlp tools to create web-scale question answering and “semantic search” engines. Massive amounts of parsed web data will also allow the automatic creation of semantic knowledge resources on an(More)
In this paper we introduce a novel system that comprises techniques advancing the query processing in wireless sensor networks. Our system facilitates time triggered queries that are scheduled in a distributed fashion among sensor nodes. Thus, time synchronisation is of paramount importance. Since accurate time synchronisation requires more energy, our(More)
We propose a novel self-training method for a parser which uses a lexicalised grammar and supertagger, focusing on increasing the speed of the parser rather than its accuracy. The idea is to train the supertagger on large amounts of parser output, so that the supertagger can learn to supply the supertags that the parser will eventually choose as part of the(More)
Modelling linguistic phenomena requires highly structured and complex data representations. Document representation frameworks (DRFs) provide an interface to store and retrieve multiple annotation layers over a document. Researchers face a difficult choice: using a heavy-weight DRF or implement a custom DRF. The cost is substantial, either learning a new(More)
The rapid growth of Internet usage has dramatically changed the way we interact with the outside world. Many people read news, communicate with friends and purchase goods online. These activities are usually done via web browsing, and web browsers record information about these activities. The recorded data can be used to understand web browsing behavior of(More)
The rapid growth of Internet usage has dramatically changed the way we interact with the outside world. Many people read news, communicate with friends and purchase goods online. These activities are usually done via web browsing. Understanding user web browsing behaviour is important in improving their browsing experience. For example, website usability(More)
There is an inherent redundancy in natural languages whereby certain common phrases (or n-grams) appear frequently in general sentences, and each time they appear, they have the same syntactic analysis. We investigate whether the speed of statistical parsers can be improved through the use of a “one structure per n-gram” hypothesis, used in a “one sense per(More)
