Generally community us to seek information for our queries and doubts. It enables the community members to post questions and answers to that. However, existing community question answering forums usually provide only textual answers, which are not informative enough for many questions. To improve the understanding and provide additional information we propose a novel scheme which allows commun...

This paper describes a full data-driven system for question answering. The system uses pattern matching and statistical techniques to identify the relevant passages as well as the candidate answers for factoid and definition questions. Since it does not consider any sophisticated linguistic analysis of questions and answers, it can be applied to different languages without requiring major adapt...

A heat pump is an electrically-ponered refrigerationcycle device which is capable ofproviding both heating and cooling to a residence. In the sumrrcr, it operates like an air conditioner by "moving" heat from inside the house to the outside. In the winter, the refrigerant flow is reversed, "moving" heat into the house by further chilling the already cold outside air and transferring the heat ga...

The audience for this toolkit is World Bank Task Managers and their counterparts in other organizations—those who, in response to requests, go to countries, assess the problems, design projects to address these problems, and implement or supervise these projects. Most World Bank staff are already overloaded with work and do not have the time to read material that is impractical or researchorien...

Without measurement, forward progress would not be possible in educational or other research contexts. Measurement, the process by which a variable is operationalized for the purpose of describing that variable in a quantitative manner (Hills, 1981; Kane, 2001), serves as the link between questions and answers. While the process of measurement bridges the gap between research objectives/questio...

This paper uses data from two online shopping platforms to investigate the economic implications of the Q&A system. This research problem becomes increasingly important as many websites start to adopt the Q&A system. Yet, its economic implications have not been discussed in the previous literature. We employ the difference-in-differences analysis to examine the effect of Q&A elements on product...

Today’s business press questions the link—by no means automatic—between individual and organizational success. Top performers or mavericks (“straight shooters”) display idiosyncratic behaviour that, while it brings innovation, puts organizational success at risk. The study reveals that individual success is a social construct that is part of the process of strategy formation and stems from a co...

The purpose of this manuscript is to describe the implementation of an action research project in a fifth grade resource classroom. Students with mild disabilities were taught how to conduct surveys using three data collection methods, display the data collected in tables and graphs, and use the data to answer survey questions.

In the paper, we present the results of an experiment with comparing the effectiveness of real text parsers of Czech language based on completely different approaches – stochastic parsers that provide dependency trees as their outputs and a meta-grammar parser that generates a resulting chart structure representing a packed forest of phrasal derivation trees. We describe and formulate main ques...
