Data Extraction using Content-Based Handles

In this paper, we present an approach and a visual tool, called HWrap (Handle Based Wrapper), for creating web wrappers to extract data records from web pages. In our approach, we mainly rely on the visible page content to identify data regions on a web page. In our extraction algorithm, we inspired by the way a human user scans the page content for specific data. In particular, we use text fea...

Hybrid Adaptive Educational Hypermedia ‎Recommender Accommodating User’s Learning ‎Style and Web Page Features‎

Personalized recommenders have proved to be of use as a solution to reduce the information overload ‎problem. Especially in Adaptive Hypermedia System, a recommender is the main module that delivers ‎suitable learning objects to learners. Recommenders suffer from the cold-start and the sparsity problems. ‎Furthermore, obtaining learner’s preferences is cumbersome. Most studies have only focused...

Effects of cognitively designed home pages with readers' prior knowledge on the web

The purpose of our ongoing efforts is to investigate the influence of web page design based on text-structure and user prior knowledge for information retrieval on the basis of navigation accuracy, speed, quality and memorization. We hypothesized that cognitively designed web home page may help low prior knowledge students organize their representation of text contents of web page. Two types of...
