Answer Retrieval From Extracted Tables
Question answering (QA) on table data, which contains densely packed information in two-dimensional form, is a challenging information retrieval task. Data can be placed at a distance from the metadata describing it. The metadata itself can be difficult to identify given the layout of a particular table. This paper describes a QA system for tables created with both machine learning and heuristi...

متن کاملSemi-Supervised Answer Extraction from Discussion Forums
Mining online discussions to extract answers is an important research problem. Methods proposed in the past used supervised classifiers trained on labeled data. But, collecting training data for each target forum is labor intensive and time consuming, thus limiting their deployment. A recent approach had proposed to extract answers in an unsupervised manner, by taking cues from their repetition...
متن کاملLearning to Answer Questions from Wikipedia Infoboxes
A natural language interface to answers on the Web can help us access information more efficiently. We start with an interesting source of information—infoboxes in Wikipedia that summarize factoid knowledge—and develop a comprehensive approach to answering questions with high precision. We first build a system to access data in infoboxes in a structured manner. We use our system to construct a ...
متن کاملLanguage Independent Answer Prediction from the Web
This work presents a strategy that aims to extract and rank predicted answers from the web based on the eigenvalues of a specially designed matrix. This matrix models the strength of the syntactic relations between words by means of the frequency of their relative positions in sentences extracted from web snippets. We assess the rank of predicted answers by extracting answer candidates for thre...
