This paper proposes and evaluates the use of linguistic information in the pre-processing phase of text mining tasks. We present several experiments comparing our proposal for selection of terms based on linguistic knowledge with usual techniques applied in the field. The results show that part of speech information is useful for the pre-processing phase of text categorization and clustering, a...

Abstract. This paper deals with the clustering task for Russian texts obtained using automatic speech recognition (ASR). The input for processing are recognition result for phone call recordings and manual text transcripts for these calls. We present a comparative analysis of clustering results for recognition texts and manual text transcripts, make an evaluation of how recognition quality affe...

OBJECTIVE To track national population indices of recall and response among smokers and recent quitters to an ongoing national televised anti-smoking campaign in Australia. METHOD National cross sectional population telephone surveys of adults. MAIN OUTCOME MEASURES Unprompted recall of advertising; recognition of advertising; campaign attributed encouragement to quit or stay quit; unprompt...

Although most smokers want to quit, the long-term success rate of quit attempts remains low; research is needed to understand the policy and environmental influences that can increase the success of cessation efforts. This paper uses regression methods to investigate self-reported exposure to policy and environmental influences on quit attempts, maintenance of a quit attempt for at least 6 mont...

BACKGROUND Smoking prevalence differs significantly across Europe. In addition, there are considerable differences in tobacco control activities across European countries. The relationship between prevalence and policy is under-researched. The present analysis examines the motivation to change smoking behaviour across 5 different European countries that differ considerably in their tobacco cont...

On the surface, the recent mobilization of opposition to the Stop Online Piracy Act (SOPA) over the internet appears to be yet another cyberactivism success. Yet, the antiSOPA movement should have been doomed to failure for two reasons. First, the issue was too abstract to mobilize local kinship and friendship groups. Second, because mass media interests were served by the bill, mass media was ...

Glutamate-inserting ochre suppressors have been identified among late-arising, spontaneous revertants of a hisG428 mutant of Salmonella typhimurium and an argE3 mutant of Escherichia coli. The S. typhimurium suppressors mapped in the tRNA2(Glu) gene gltU at 82 min; those in E. coli were found to be in tRNA2(Glu) genes gltW at 56 min, gltU at 85 min, and gltT at 90 min.

We present the tool UFIT (Uppaal Fault Injector for Timed automata). In UFIT, we model five types of faults, namely, message loss, transient, byzantine, stuck-at, and fail-stop faults. Given the fault-free timed automata model and the selection of a type of fault, UFIT models the faults and generates the fault-affected timed automata model automatically. As a result, the designer can analyze th...
