Rule Learning for Feature Values Extraction from HTML Product Information Sheets
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
The paper presents a technique for learning extraction rules of product information from such product information sheets. ...
In this paper we assume that product information is represented as a set of feature-value pairs contained in an HTML product information sheet that is usually formatted using HTML tables. ...
Experimental Results We ran a series of experiments of rule learning for IE from the Hewlett Packard's Web site. The task was to extract the printers feature values from their information sheets. ...

We also define a convenient way for mapping L-wrappers to XSLT for efficient processing using available XSLT processing engines. ...
The developed Logic wrappers (L-wrapper) have declarative semantics, and therefore: (i) their specification is decoupled from their implementation and (ii) they can be generated using inductive logic programming ...
Consider the Hewlett Packard's site of electronic products 3 and the task of IE from a product information sheet for printers. ...

ACE is an unsupervised method that looks at both text and HTML tags. We upgrade ACE into Improved Concept Extractor (ICE) with significant improvements. KEA is a supervised learning system. ...
Concept extraction is a nice solution for this purpose. In this paper, we investigate two concept extraction methods: Automatic Concept Extractor (ACE) and Automatic Keyphrase Extraction (KEA). ...
For each candidate, two feature values, TFIDF and first occurrence, are calculated. ...

The mapping actually shows how the theory can be applied to obtain efficient wrappers for information extraction from HTML. ...
Recently it was shown that existing general-purpose inductive logic programming systems are useful for learning wrappers (known as L-wrappers) to extract data from HTML documents. ...
Rule bodies check various token features like: length, position in the text fragment, if they are numeric or capitalized, a.o. SRV has been adapted to learn information extraction rules from HTML. ...
