Title : Semantic content negotiation for knowledge interchange among heterogeneous systems

Beginning of thesis : 2020
End of thesis : 2024

Abstract : Content negotiation on the Web allows a data consumer (client) to tell a data provider (server) what it expects in terms of format, language, encoding, security. In return, the server provides data that meets these expectations when it can, or indicates an alternative, for example, that the same information resource is available in another format. However, even when the client’s request is satisfied, this does not mean that the client is able to interpret the data correctly

In particular, in applications that rely on Semantic Web technologies, such as RDF and OWL, an application could expect graph-based data that conform to a specific ontology, or that fit a certain data shape, or that is compatible with a given entailment regime. In environments such as the Web of Things, strong constraints may impose requirements on the server or client side due to processing power, bandwidth, or memory limitations.

The main challenge is to find out how clients and servers can agree on the expected (client-side) or provided (server-side) content automatically, so without the developer of the client application having to contact the server manager, or read natural language documentation.

Keywords : Content negotiation, Semantic web, RDF, Client-Server

  • [emse-04138801] Enable Decentralised Semantic Content Negotiation through Equivalence Links
    The Web is a decentralised system where servers can serve a set of URIs that identify resources. A resource may have one or more representations [2]. This encourages Content Negotiation (CN), the mechanism by which a client can request a resource representation that satisfies some constraints [1, Section 12]. In the SemanticWeb, resources are described […]
  • [emse-03843924] A Portal for the State of the Art on Content Negotiation
    Resources on the Web are identified by Uniform Resource Identifiers (URIs), and can be accessed using web protocols such as HTTP. A resource can have several representations varying along a set of dimensions, forming a set of variants. Content negotiation (CN) is the mechanism for selecting the appropriate variant that conforms to a set of […]
  • [hal-03837655] Négociation de contenu sur le Web: un état de l’art
    L’ouverture et l’accessibilité du Web a largement contribué à son adoption à l’échelle mondiale. L’identifiant uni forme de ressource (URI) est la pierre angulaire de l’identification des ressources sur le Web. Une ressource sur le Web peut être décrite de nombreuses façons, ce qui peut rendre difficile pour un utilisateur de trouver une représentation adéquate. […]
  • [hal-03765368] Négociation de contenu sémantique pour l'échange de connaissances entre systèmes hétérogènes
    Les ressources sur le Web sont identifiées par des identificateurs uniformes de ressources (URI). Chaque ressource peut avoir plusieurs représentations la décrivant, que nous appelons variantes. Un utilisateur (client) souhaitant une représentation particulière de cette ressource fait une requête à son URI avec un ensemble de contraintes. La négociation de contenu (NC) est le processus […]
  • [emse-03656955] Content negotiation on the Web: State of the art
    The openness and accessibility of the Web has contributed greatly to its worldwide adoption. Uniform Resource Identifiers (URIs) are used for resource identification on the Web. A resource on the Web can be described in many ways, which makes it difficult for a user to find an adequate representation. This situation has motivated fruitful research […]
