Mining the Web for Lexical Knowledge to Improve Keyphrase Extraction: Learning from Labeled and Unlabeled Data [article]

Peter D. Turney
2002 arXiv   pre-print
The task of automatic keyphrase extraction is to select keyphrases from within the text of a given document.  ...  In this paper, I introduce new features that are derived by mining lexical knowledge from a very large collection of unlabeled data, consisting of approximately 350 million Web pages without manually assigned  ...  Thanks to my colleague Alain Désilets for suggesting, by example, the idea of using a Web search engine as a source of input for an algorithm.  ...

Knowledge extraction from web-based application source code: An approach to database reverse engineering for ontology development

Shuxin Zhao, Elizabeth Chang, Tharam Dillon
2008 2008 IEEE International Conference on Information Reuse and Integration  
This paper presents a novel approach for extracting knowledge from web-based application source code in supplementing and assisting ontology development from database schemas.  ...  A knowledge processing and integration model for extracting and integrating the knowledge embedded in the source code for ontology development is then proposed.  ...  The extraction processes are described as the following: 1. All the pairs of Data Label and Data Carrier are extracted from each of the source code files based on the Data Label Extraction Rules. 2.  ...

2009 ACM Transactions on Database Systems  
Data extraction, which is important for many applications, extracts the records from the HTML files automatically.  ...  We present a novel data extraction method, ODE (Ontology-assisted Data Extraction), which automatically extracts the query result records from the HTML pages.  ...  from the same Web site, there may still be some data that cannot be labeled.  ...

Simultaneous record detection and attribute labeling in web data extraction

Jun Zhu, Zaiqing Nie, Ji-Rong Wen, Bo Zhang, Wei-Ying Ma
2006 Proceedings of the 12th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '06  
Recent work has shown the feasibility and promise of templateindependent Web data extraction.  ...  In our approach, record detection can benefit from the availability of semantics required in attribute labeling and, at the same time, the accuracy of attribute labeling can be improved when data records  ...  studies show that mutual enhancement of record detection and attribute labeling can be achieved in our joint approach, and HCRFs can perform very well on both list and detail Web pages.  ...

Reverse method for labeling the information from semi-structured web pages [article]

Z. Akbar, L.T. Handoko
2009 arXiv   pre-print
We propose a new technique to infer the structure and extract the tokens of data from the semi-structured web sources which are generated using a consistent template or layout with some implicit regularities  ...  The attributes are extracted and labeled reversely from the region of interest of targeted contents. This is in contrast with the existing techniques which always generate the trees from the root.  ...  THE REVERSE MECHANISM No matter the method used to extract and to label the tokens from a web template or layout, correct initial setup is crucial for further data extraction.  ...

Information Extraction from Web Pages Using Presentation Regularities and Domain Knowledge

Srinivas Vadrevu, Fatih Gelgi, Hasan Davulcu
2007 World wide web (Bussum)  
World Wide Web is transforming itself into the largest information resource making the process of information extraction (IE) from Web an important and challenging problem.  ...  The resulting documents are weakly annotated in the sense that they might contain many incorrect annotations and missing labels.  ...  ExAlg [3] is another system that can extract data from template generated Web pages.  ...

Automatic annotation of data extracted from large Web sites

Luigi Arlotta, Valter Crescenzi, Giansalvatore Mecca, Paolo Merialdo
2003 International Workshop on the Web and Databases  
Data extraction from web pages is performed by software modules called wrappers. Recently, some systems for the automatic generation of wrappers have been proposed in the literature.  ...  However, due to the automatic nature of the approach, the data extracted by these wrappers have anonymous names.  ...  We have then used these wrappers to extract data from the input pages. Finally, we have run Labeller to annotate the extracted data with a label extracted from the input pages.  ...
