Template Induction over Unstructured Email Corpora

Julia Proskurnia, Marc-Allen Cartright, Lluis Garcia-Pueyo, Ivo Krka, James B. Wendt, Tobias Kaufmann, Balint Miklos
2017 Proceedings of the 26th International Conference on World Wide Web - WWW '17  
Unsupervised template induction over email data is a central component in applications such as information extraction, document classification, and auto-reply.  ...  However much less work has been done in performing the same task over unstructured email data.  ...  Given this setting, the primary task becomes one of establishing that template induction can be effective for the unstructured content.  ...

Survey of Stages of Developing the Information Extraction Systems from the Web

Asmaa Ahmed Hamed Khalil Elsaeidy
2015 International Journal Of Mechanical Engineering And Information Technology  
The traditional information extraction systems are focused on satisfying precise, narrow and pre-specified requests from small homogenous corpora.  ...  Wrapper induction is a special group of methods based on the fact that most web pages are generated by templates.  ...  Today's enterprises are generating and consuming rapidly increasing quantities of unstructured textual data like emails, web pages, news articles, blog posts, online reviews and comments and call centre  ...

Ontology-based information extraction: An introduction and a survey of current approaches

Daya C. Wimalasuriya, Dejing Dou
2010 Journal of information science  
However, since no such conferences or standard text corpora currently exist for OBIE, most researchers have compiled their own corpora for OBIE systems.  ...  As such, it can be expected that having standard text corpora and well defined tasks will have a similar positive impact on the development of ontology based information extraction.  ...  They can be either unstructured (e.g., text files) or semi-structured (e.g., web pages using a particular template such as pages from Wikipedia).  ...
