In this paper we present an application of information extraction technologies to data mining. The system has the goal of producing reliable reports on opinions that customers express about companies and/or products. Information extraction is regarded as an enabling technology by which structured databases can be populated from unstructured texts available(More)
The identification of biological markers of Alzheimer's disease (AD) can be extremely useful to improve diagnostic accuracy and/or to monitor the efficacy of putative therapies. In this regard, peripheral cells may be of great importance, because of their easy accessibility. After subjects were grouped according to diagnosis, the expression of(More)
In this paper, a distributed power control mechanism for ad hoc networks is proposed and investigated. This mechanism, acting at different layers, reduces the power consumption maintaining similar behavior, in terms of delay and throughput, as classic schemes. In the proposed strategy, the generic sender uses an appropriate power level to transmit its(More)

The DepAuDE project wants to develop a design framework to evaluate which techniques, tools and methodologies are best suited to obtain dependability for embedded applications that are distributed on multiple levels. In a second step, it will develop and evaluate elements (both intra-site and inter-site) of an architecture to make these applications more(More)
This paper describes CELI's participation to the EVALITA 2009 dependency evaluation task, which was based on a symbolic dependency grammar for Italian. The discussion on the results achieved by such a grammar emphasizes the fact that they are obtained by linearizing the CoNLL input and parsing it from scratch, thus generating extra errors due to lexicon(More)
Glioblastoma (GBL) is the most malignant brain tumour in adults, causing the death of most patients within 9-12 months of diagnosis. Treatment is based on a combination of surgery, radiation therapy, and chemotherapy. With these treatment modalities, however, responses are extremely poor, so identification of novel treatment strategies is highly warranted.(More)
Markers of oxidative and nitrosative stress have been found in spinal cord, cortex, cerebrospinal fluid and plasma of patients affected by amyotrophic lateral sclerosis (ALS), a fatal disorder characterised by progressive motor neuron degeneration. In this study, we investigated the effect of the NO-releasing agent, diethylamine NONOate (NONO), on(More)
Recently there has been a growing interest in infrastructures for sharing NLP tools and resources. This paper presents SiSSA, a project that aims at developing an infrastructure for prototyping, editing and validation of NLP application architectures. The system will provide the user with a graphical environment for (1) selecting the NLP activities relevant(More)
We will present a new model of grammar documentation which exploits the potentialities of an hypertextual representation of lingware. As we will show this model insures the following benefits: • Constant coherence between the documentation and the various pieces of linguistic information. • Valuable organization of the linguistic knowledge, in order to(More)
In recent years there has been a growing interest in the commercial deployment of NLP technologies. This paper presents SiSSA, a project whose main aim is that of developing an infrastructure for prototyping, editing and validation of NLP application architectures. The system will provide the user with a graphical environment for (1) selecting the NLP(More)
