Reverse Engineering of Relational Databases to Ontologies [chapter]

Irina Astrova
2004 Lecture Notes in Computer Science  
We propose a novel approach to reverse engineering of relational databases to ontologies. Our approach is based on the idea that semantics of a relational database can be inferred, without an explicit analysis of relational schema, tuples and user queries. Rather, these semantics can be extracted by analyzing HTML forms, which are the most popular interface to communicate with relational databases for data entry and display on the Web. The semantics are supplemented with the relational schema
more » ... d user "head knowledge" to build an ontology. Our approach can be applied to migrating data-intensive Web pages, which are usually based on relational databases, to the ontologybased Semantic Web.

Web Page Personalization to Improve e-Accessibility for Visually Impaired People

Yoann Bonavero, Marianne Huchard, Michel Meynard
2014 Irina Astrova. WEB   unpublished
Today's assistive technologies aim to improve the quality of information acquisition for visually impaired persons. Screen readers and screen magnifiers are the main visual assis-tive technologies that are currently proposed. However, due to economical reasons, these technologies do not consider specific needs of visually impaired people. In this paper, we propose an approach to make Web pages more accessible for users who have specific needs. User wishes, like text color, font size, link color
more » ... or even more complex wishes including wishes about brightness or contrast are encoded as user preferences. We also encode designer graphical choices as designer preferences. From these preferences, a new Web page design is computed using a resolution algorithm. We compare two distinct approaches to make this computation: resolution algorithms from preference theory domain and an evolutionary algorithm. The comparison evaluates running time on automatically generated data and on the sign in Facebook page.
