Aggregated search: From information nuggets to aggregated documents
نویسنده
چکیده
The aggregated search assembles in one interface information from different sources. It deals with different types of content (text, video, image, etc) and granularities of retrieval. It aims to assemble the retrieved content forming an aggregated result. This is in contrast with the common approach which provides a list of documents as the search result. Today we are able to retrieve content of different types and granularities, but little work has been done for their aggregation. Being a new area of research formalization of aggregated search is still missing. This paper treats the problem in a high level of abstraction. It presents the state of the art and decomposes the problem, listing issues and providing examples and formalization. This work aims to be a base of reflection and a reference for future work. RÉSUMÉ. Le but de la recherche agregée est de rassembler des informations provenant de plusieurs sources en une seule interface. Elle doit ainsi gérer des problématiques liées aux différents types de contenu (texte, vidéo, image, etc) ainsi qu’à la granularité des résultats. La formation d’un contenu agrégé à partir de différents types de contenus retrouvés contraste avec l’approche commune en RI consistant à renvoyer à l’utilisateur une liste ordonnée de résultats. Si nous sommes aujourd’hui capables de retrouver de l’information de différents types et de différente granularité, très peu de travaux existent concernant leur agrégation. La recherche agrégée étant un domaine de recherche récent, elle manque encore de formalisation. Ce papier se propose de traiter la recherche agrégée à un niveau d’abstraction élevé. Il présente tout d’abord l’état de l’art, puis décompose le problème en listant et formalisant les différentes problématiques. Ce travail doit servir de base de réflexion et de référence pour de futurs travaux sur le domaine.

Approaches to implement and evaluate aggregated search
Aggregated search or aggregated retrieval can be seen as a third paradigm for information retrieval following the boolean retrieval paradigm and the ranked retrieval paradigm. In the first two, we are returned respectively sets and ranked lists of search results. It is up to the time-poor user to scroll this set/list, scan within different documents and assemble his/her information need. Altern...
متن کاملUne approche de recherche d'attributs pertinents pour l'agrégation d'information
Given a query, aggregated search aims at aggregating information nuggets retrieved from differents sources. The aggregated result is a coherent answer that can be seen as an alternative to the traditional ranked list of documents. We focus in this paper on relational aggregated search where information nuggets are mainly classes, instances and attributes. We present a result aggregation approac...

متن کاملFederated Aggregated Search
Federated Aggregated Search by Andrés Marenco Zúñiga The traditional search engine paradigm has changed from retrieving simple text documents, to selecting a broader combination of diverse document types (i.e. images, videos, maps...) that could satisfy the user’s information need. Each type of document, stored in specialized databases known as ‘verticals’, and found in either local or federate...
متن کاملA Task-Based Evaluation of an Aggregated Search Interface
This paper presents a user study that evaluated the effectiveness of an aggregated search interface in the context of non-navigational search tasks. An experimental system was developed to present search results aggregated from multiple information sources, and compared to a conventional tabbed interface. Sixteen participants were recruited to evaluate the performance of the two interfaces. Our...
