Personalized knowledge organization and access for the web

Journal of Research and Practice in Information Technology, 2012

This paper proposes a retrieval architecture based on clustering techniques to search the web for resources that are potentially useful for educational purposes. This architecture makes use of Formal Concept Analysis to search the web as a sort of learning object repository and returns a clustering of results based on pedagogical criteria that can help providing a rich environment for content authoring, enhancing the possibilities of traditional search based on metadata. The retrieval system is designed to be seamlessly embedded ...

Classifier for the Internet Resource Discovery (ACIRD), which uses machine learning techniques to organize and retrieve Internet documents. ACIRD consists of a knowledge acquisition process, document classifier and two-phase search engine. T he knowledge acquisition process of ACIRD automatically learns classification knowledge from classified Internet documents. The document classifier applies learned classification knowledge to classify newly collected Internet documents into one or more classes.

In the access to the unstructured information, the representation of the relevant concepts is a fundamental issue for the sharing of the knowledge between indexers and users. The browsing of the concepts can play an important role in the user interface. We present an implementation of an interface that will give the possibility of interacting with a conceptual structure of the documents, and of making a graphical navigation on the thesauri available on the different fields.

I am deeply grateful to my advisor James Allan for his support and guidance through all my work. To paraphrase a Russian proverb, he helped me to see the forest behind the trees -he helped me to stay aware and appreciate the bigger picture behind the small details of the everyday research problems.

This paper discusses an integrated approach to information handling and knowledge management in web-based open-ended learning environments. It supports both learners and instructors in information structuring and taskoriented processing and usage. AIMS, a web-based intelligent tool for task-based information and performance support is implemented to exemplify the theoretical assumptions of this approach. AIMS focuses on three important aspects of the information handling process -information structuring, information visualization, and user centered approach. We employ concept maps (CM) to build a subject domain ontology and use it as a basis for defining course structures. The domain CM is also used for attractive non-linear visualization and conceptual graphical navigation of the subject domain and the search results, thus allowing for more efficient information searches. In order to provide appropriate adaptation to the individual information needs and preferences of the learners AIMS models their behavior.

This paper presents an ongoing study of the development of a customizable web browser information organization and management system, which the author has named Lexicon Sextant (LS). LS is a user friendly, graphical web based add-on to the latest generation of web browsers, such as Google Chrome, making it easier and more intuitive to store and retrieve favorites (bookmarks) since it only uses two levels (six main headings & 12 sub-headings). A total of 98 participants completed the task of categorizing 18 thumbnails from specific websites, together with 18 thumbnails from random websites, under six main LS headings, i.e. Work, Lifestyle, Travel, Health, Education, and Money. This was followed by a recall exercise of 12 randomly generated websites. The results showed that the participants had a better correction rate in Money and Lifestyle, but a worse correction rate in Work and Education among the overall correction rate, appointed correction rate, and self-chosen correction rate, in terms of each category task performance.

Abstract: We redesign the user interface of an online library catalog, leveraging current web technologies that allow dynamic and fine-grained user interaction. Over the course of our iterative design and test cycle, we identified four key areas where such dynamic web technologies can be used to improve the support for typical information seeking strategies, namely: 1) the user of overview+ details, 2) a tabular data display, 3) using tabs as a history mechanism and 4) embedding a suggestion bar.
