A Supervised Visual Wrapper Generator for Web-Data Extraction
Extracting data from Web pages using wrappers is a fundamental problem arising in a large variety of applications of vast practical interest. In this paper, we propose a novel schema-guided approach to wrapper generation. We provide a user-friendly interface that allows users to define the schema of the data to be extracted, and specifies mappings from a HTML page to the target schema. Based on...
متن کاملSelf-Supervised Synonym Extraction from the Web
Current synonym extraction methods work in a “closed” way. Given the problem word and set of target words, researchers have to choose words synonymous with the problem word using features such as lexical patterns and distributional similarities. This paper tries to discover synonyms in an “open” way and presents a synonym extraction framework based on self-supervised learning. We first analysis...
متن کاملWeb Data Knowledge Extraction
A constantly growing amount of information is available through the web. Unfortunately, extracting useful content from this massive amount of data still remains an open issue. The lack of standard data models and structures forces developers to create adhoc solutions from the scratch. The figure of the expert is still needed in many situations where developers do not have the correct background...
متن کاملOLERA: A Semi-supervised Approach for Web Data Extraction with Visual Support
Information extraction (IE) from semi-structured Web documents plays an important role for a variety of information agents. Over the past few years, researchers have developed a rich family of generic IE techniques based on supervised approaches which learn extraction rules from user-labelled training examples. However, annotating training data can be expensive when thousands of data sources ne...
متن کاملSeed Selection for Distantly Supervised Web-Based Relation Extraction
In this paper we consider the problem of distant supervision to extract relations (e.g. origin(musical artist, location)) for entities (e.g. ‘The Beatles’) of certain classes (e.g. musical artist) from Web pages by using background information from the Linking Open Data cloud to automatically label Web documents which are then used as training data for relation classifiers. Distant supervision ...
