Acquisition of Noncontiguous Class Attributes from Web Search Queries
نویسنده
چکیده
Previous methods for extracting attributes (e.g., capital, population) of classes (Empires) from Web documents or search queries assume that relevant attributes occur verbatim in the source text. The extracted attributes are short phrases that correspond to quantifiable properties of various instances (ottoman empire, roman empire, mughal empire) of the class. This paper explores the extraction of noncontiguous class attributes (manner (it) claimed legitimacy of rule), from factseeking and explanation-seeking queries. The attributes cover properties that are not always likely to be extracted as short phrases from inherently-noisy queries.

متن کاملAttribute Extraction from Synthetic Web Search Queries
The accuracy and coverage of existing methods for extracting attributes of instances from text in general, and Web search queries in particular, are limited by two main factors: availability of input textual data to which the methods can be applied, and inherent limitations of the underlying assumptions and algorithms being used. This paper proposes a weakly-supervised approach for the acquisit...

The role of Web search queries has been demonstrated in the extraction of attributes of instances and classes, or of sets of related instances and their class labels. This paper explores the acquisition of opendomain commonsense knowledge, usually available as factual knowledge, from Web search queries. Similarly to previous work in open-domain information extraction, knowledge extracted from t...
متن کاملTurning Web Text and Search Queries into Factual Knowledge: Hierarchical Class Attribute Extraction
A seed-based framework for textual information extraction allows for weakly supervised acquisition of open-domain class attributes over conceptual hierarchies, from a combination of Web documents and query logs. Automaticallyextracted labeled classes, consisting of a label (e.g., painkillers) and an associated set of instances (e.g., vicodin, oxycontin), are linked under existing conceptual hie...
