  • We propose a method to generate large-scale encyclopedic knowledge, which is valuable for much NLP research, based on the Web. We first search the Web for pages containing a term in question. Then we use linguistic patterns and HTML structures to extract text fragments describing the term. Finally, we organize extracted term descriptions based on word senses and domains. In addition, we apply an automatically generated encyclopedia to a question answering system targeting the Japanese InformationTechnology Engineers Examination. ...

  • Semantic relations between text concepts denote the core elements of lexical semantics. This paper presents a model for the automatic detection of INTENTION semantic relation. Our approach first identifies the syntactic patterns that encode intentions, then we select syntactic and semantic features for a SVM learning classifier. In conclusion, we discuss the application of INTENTION relations to Q&A.

  • A complex relation is any n-ary relation in which some of the arguments may be be unspecified. We present here a simple two-stage method for extracting complex relations between named entities in text. The first stage creates a graph from pairs of entities that are likely to be related, and the second stage scores maximal cliques in that graph as potential complex relation instances. We evaluate the new method against a standard baseline for extracting genomic variation relations from biomedical text. ing named entities.

  • QA-by-Dossier-with-Constraints is a new approach to Question Answering whereby candidate answers’ confidences are adjusted by asking auxiliary questions whose answers constrain the original answers. These constraints emerge naturally from the domain of interest, and enable application of real-world knowledge to QA. We show that our approach significantly improves system performance (75% relative improvement in F-measure on select question types) and can create a “dossier” of information about the subject matter in the original question. ...

  • This paper describes F ERRET, an interactive question-answering (Q/A) system designed to address the challenges of integrating automatic Q/A applications into real-world environments. F ERRET utilizes a novel approach to Q/A – known as predictive questioning – which attempts to identify the questions (and answers) that users need by analyzing how a user interacts with a system while gathering information related to a particular scenario.

  • Even though the question answering (QA) field appeared only in recent years, there are systems for English which obtain good results for opendomain questions. The situation is very different for other languages, mainly due to the lack of NLP resources which are normally used by QA systems. In this paper, we present a project which develops a QA system for Romanian. The challenges we face and decisions we have to make are discussed.

  • Question answering research has only recently started to spread from short factoid questions to more complex ones. One significant challenge is the evaluation: manual evaluation is a difficult, time-consuming process and not applicable within efficient development of systems. Automatic evaluation requires a corpus of questions and answers, a definition of what is a correct answer, and a way to compare the correct answers to automatic answers produced by a system.
