The general topic of the thesis is web search. It focused on how to leverage the data semantics for exploratory search. Exploratory search refers to cognitive consuming search tasks that are open-ended, multi-faceted, and iterative like learning or topic investigation. Semantic data and linked data in particular offer new possibilities to solve...

Two strong tendencies in social networks today are their growing multidimensionality and the key role of social objects around which they crystallize. We define OCSO as semantic web schema to describe finely these social objects and their afferent social activity. Then we defend the use of spreading activation algorithms to perform complex...

Le concept d'objet social est structurant pour le web à l'heure où le découplage entre plateformes de contenus et plateformes sociales s'accentue. Nous étudions dans cet article la notion d'objet social au travers d'un faisceau d'évolutions technologiques qui lui sont favorables. Premièrement les technologies du web sémantique et leur...

This paper makes a focus on social objects and stresses the importance of object-centered sociality in emerging technological context. Actual digital object centered sociality limits and related challenges are reviewed. We propose to foster social interactions through advanced social objects recommendations. In this context the Object Centered...

Web Science is an interdisciplinary arena. Motivated by the unforeseen scale and impact of the web, it addresses web-related research questions in a holistic manner, incorporating perspectives from a broad set of disciplines. There has been ongoing discussion about which disciplines are more or less present in the community, and about defining...

Exploratory search systems help users learn or investigate a topic. The richness of the linked open data can be used to assist this task. We present a method that selects and ranks linked data resources that are semantically related to the user's interest. The objective is to focus the user's attention on a meaningful subset of highly...

Exploratory search systems are built specifically to help the user in his cognitive consuming search tasks like learning or topic investigation. Some of these systems are built on the top of linked data and use semantics to provide cognitively-optimized search experiences. Thanks to their richness and to their connected nature linked data...

A promising scenario for combining linked data and search is exploratory search. During exploratory search, the search objective is ill-defined and favorable to discovery. A common limit of the existing linked data based exploratory search systems is that they constrain the exploration through single results selection and ranking schemes. The...
