Collaborative Information Retrieval: Concepts, Models and Evaluation
Recent work have shown the potential of collaboration for solving complex or exploratory search tasks allowing to achieve synergic effects with respect to individual search, which is the prevalent information retrieval (IR) setting this last decade. This interactive multi-user context gives rise to several challenges in IR. One main challenge relies on the adaptation of IR techniques or models ...
متن کاملAn Evaluation of Term Dependence Models in Information Retrieval
In practical retrieval environments the assumption is normally made that the terms assigned to the documents of a collection occur independently of each other. The term independence assnmption is unrealistic in many cases, but its use leads to a simple retrieval algorithm. More realistic retrieval systems take into account dependencies between certain term pairs and possibly between term triple...
متن کاملEvaluation of Vector Space Models for Medical Disorders Information Retrieval
Nowadays, consumers often search online to seek medical and health care information that they need. To improve this access, the ShARe/CLEF eHealth Evaluation Lab (SHEL) organized a shared task on information retrieval for Medical Disorders in 2013. This paper describes our participation in this task. In order to detect latent semantic relevance between queries and webpages about disorders, a se...
متن کاملInformation Retrieval Models
Many applications that handle information on the internet would be completely inadequate without the support of information retrieval technology. How would we find information on the world wide web if there were no web search engines? How would we manage our email without spam filtering? Much of the development of information retrieval technology, such as web search engines and spam filters, re...
متن کاملModels in Information Retrieval
Retrieval models form the theoretical basis for computing the answer to a query. They differ not only in the syntax and expressiveness of the query language, but also in the representation of the documents. Following Rijsbergen’s approach of regarding IR as uncertain inference, we can distinguish models according to the expressiveness of the underlying logic and the way uncertainty is handled. ...
