We present a new freely available dictionary of paraphrases of Czech complex predicates with light verbs, ParaDi. Candidates for single predicative paraphrases of selected complex predicates have been extracted automatically from large monolingual data using word2vec. They have been manually verified and further refined. We demonstrate one of many possible applications of ParaDi in an experimen...

In Question Answering a major challenge is the fact that similar meaning is very often expressed with different surface realizations in questions and in sentences containing the answer. In this paper we propose an enriched syntax-based representation which helps deal with this widespread variability and provides a degree of generalization. We encode uncertainty about the syntactic structure of ...

In this research, we extract paraphrases from Japanese Web news articles that are long and aimed at displaying on personal computer screens and mobile news articles that are short and compact and aimed at mobile terminals’ small screens. We have collected them for more than two years, and aligned them at article level and then at sentence level. As the result, we got more than 88,000 pairs of a...

We present an approach to the new task of opinion holder and target extraction on opinion compounds. Opinion compounds (e.g. user rating or victim support) are noun compounds whose head is an opinion noun. We do not only examine features known to be effective for noun compound analysis, such as paraphrases and semantic classes of heads and modifiers, but also propose novel features tailored to ...

This position paper looks critically at a number of aspects of current research into spoken language translation (SLT) in the medical domain. We first discuss the user profile for medical SLT, criticizing designs which assume that the doctor will necessarily need or want to control the technology. If patients are to be users on an equal standing, more attention must be paid to usability issues....

In this paper, we describe SemEval-2013 Task 4: the definition, the data, the evaluation and the results. The task is to capture some of the meaning of English noun compounds via paraphrasing. Given a two-word noun compound, the participating system is asked to produce an explicitly ranked list of its free-form paraphrases. The list is automatically compared and evaluated against a similarly ra...

Architecture is not only a complex including materials and methods to provide a shelter for human beings, but also it is an expression of the society, which created that. Its form will be the reflection of values and religious orientation besides social maturity of the related society and its structure will narrate the nature, power and different dimensions of mythical and psychological aspects...

Question answering (QA) systems are sensitive to the many different ways natural language expresses the same information need. In this paper we turn to paraphrases as a means of capturing this knowledge and present a general framework which learns felicitous paraphrases for various QA tasks. Our method is trained end-toend using question-answer pairs as a supervision signal. A question and its ...
