For research and development of an approach for automatically answering why-questions (why-QA) a data collection was created. The data set was obtained by way of elicitation and comprises a total of 395 why-questions. For each question, the data set includes the source document and one or two user-formulated answers. In addition, for a subset of the questions, user-formulated paraphrases are av...

Audiences have most likely always been subject to distraction and drift during all varieties of presentation. While these activities were often confined to solitary activities since inter-person distractions were limited by their visibility to the speaker (ever been caught passing notes in class?), in the current networked-enabled presentation room, multi-person off-task "distractions" are now ...

In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...

Helping behavior is a significant part of social learning process in online games. One type of such a behavior is answering questions in a chat. We provide a method to detect if the question asked in a chat was answered and by whom. Proposed method is based on topic modeling for chat messages and comparison of a detected topic of question with a topic of possible reply. We show its efficiency o...

High energy muon colliders, such as the TeV-scale conceptual designs now being considered, are found to produce enough high energy neutrinos to constitute a potentially serious off-site radiation hazard in the neighbourhood of the accelerator site. A general characterization of this radiation hazard is given, followed by an order-of-magnitude calculation for the off-site annual radiation dose a...

Although simple additive weighting method (SAW) is the most popular approach for classical multiple attribute decision making (MADM), it is not practical any more if information is fuzzy. The existing methods of Fuzzy Simple Additive Weighting method (FSAW) apply defuzzification which distorts fuzzy numbers. Furthermore, most of the methods usually require lengthy and laborious manipulations. I...

Providing support for distributed agile teams as they conduct planning meetings is tricky. In distributed settings, the use of paper index cards for planning isn’t convenient, as some of the team members do not have access to the physical cards. We present the results of an observational study where a distributed card based planning tool was evaluated against planning with physical cards. The f...

Given the highly political nature of abortion in the United States, the provision of medical abortion with mifepristone (Mifeprex®) and misoprostol has always occurred under a unique set of circumstances. The Food and Drug Administration-approved regimen requires clinicians to administer the mifepristone in the office and also requires women to return to the office for the misoprostol. In the U...

With the increase of online customer opinions in specialised websites and social networks, the necessity of automatic systems to help to organise and classify customer reviews by domain-specific aspect/categories and sentiment polarity is more important than ever. Supervised approaches for Aspect Based Sentiment Analysis obtain good results for the domain/language they are trained on, but havin...

The present research investigated younger and older adults’ communicative goals and their effects on off-topic speech for autobiographical narratives. Participants indicated their communicative goals by rating preferences among paired goals, e.g., focus-fascinating, one of which was designated as an expressive goal, appropriate for producing elaborative speech, and one which was an objective go...
