Abstract

LongEval-Retrieval is a Web document retrieval benchmark that focuses on continuous retrieval evaluation. This test collection is intended to be used to study the temporal persistence of Information Retrieval systems and will be used as the test collection in the Longitudinal Evaluation of Model Performance Track (LongEval) at CLEF 2023. This benchmark simulates an evolving information system environment - such as the one a Web search engine operates in - where the document collection, the query distribution, and relevance all move continuously, while following the Cranfield paradigm for offline evaluation. To do that, we introduce the concept of a dynamic test collection that is composed of successive sub-collections each representing the state of an information system at a given time step. In LongEval-Retrieval, each sub-collection contains a set of queries, documents, and soft relevance assessments built from click models. The data comes from Qwant, a privacy-preserving Web search engine that primarily focuses on the French market. LongEval-Retrieval also provides a 'mirror' collection: it is initially constructed in the French language to benefit from the majority of Qwant's traffic, before being translated to English. This paper presents the creation process of LongEval-Retrieval and provides baseline runs and analysis.

Abstract

We describe here an experimental framework and the results obtained on microblogs retrieval. We study the contribution one popular approach, i.e., words embeddings, and investigate the impact of the training set on the learned embedding. We focus on query expansion for the retrieval of tweets on the CLEF CMC 2016 corpus. Our results show that using embeddings trained on a corpus in the same domain as the indexed documents did not necessarily lead to better retrieval results., Comment: 23 pages. in French

13. Toward Word Embedding for Personalized Information Retrieval

Abstract

This paper presents preliminary works on using Word Embedding (word2vec) for query expansion in the context of Personalized Information Retrieval. Traditionally, word embeddings are learned on a general corpus, like Wikipedia. In this work we try to personalize the word embeddings learning, by achieving the learning on the user's profile. The word embeddings are then in the same context than the user interests. Our proposal is evaluated on the CLEF Social Book Search 2016 collection. The results obtained show that some efforts should be made in the way to apply Word Embedding in the context of Personalized Information Retrieval.

Abstract

International audience; Classical evaluations of Information Retrieval systems, under the Cranfield Paradigm, compare several systems within one evaluation environment, defined by its settings (document collection, topics, assessments and evaluation measures). In this paper, we propose a framework to handle the comparison of systems across several evaluation environments. To achieve this goal, we investigate the use of pivot systems, allowing an indirect comparison of systems across evaluation environments by computing Result Deltas, i.e. the differences between their evaluation measures values. We detail the proposed pivot-based methodology, define a pivot characteristics and present experiments to validate our proposal (and in particular the pivot characteristics). We create altered environments that differ from their topic sets using the 2018 and 2020 CLEF eHealth evaluation campaigns (Goeuriot et al., 2020). We explore the behaviour of the metrics and pivots measuring the correlation between the result deltas, and the ranking of systems through the pivots compared to the official ranking of the systems. Our experiment show that correlations can greatly vary according to the chosen pivot and metric. We show that some pivot/metric pairs achieve high correlation values across the altered environments, with a ranking of systems similar to the official ranking.

Abstract

International audience; Focused retrieval retrieves and ranks sub-parts of documents according to their estimated relevance to a query. Many approaches akin to Structured Document retrieval exploit documents structure to effectively retrieve logic elements (titles, sections, etc...). Other approaches like Passage Retrieval aim at retrieving arbitrary length text unit (passages), considering the document as a unstructured flat text. In this work, we use the best of the two worlds. We want to (1) retrieve passages to find the best text units to retrieve ; (2) exploit the document's structure to more effectively estimate the passages' relevance. Previous work has shown that leveraging on the passage context was efficient for passage ranking. We believe that the information given by a document's structure can be used to estimate its passages' context. Firstly, we propose several ways to represent and integrate a document's structure and its sub-structures elements (sections) in the estimation of its passages' context. Secondly, we integrate these passage contexts in a state-of-the-art passage retrieval model. We evaluate our approach on two passage retrieval tasks on structured documents: CLEF IP2012 and CLEF IP2013. Our results show that using a document's structure to estimate its passages' contexts improves retrieval performances.

Abstract

International audience; This paper describes the work done by the LIG of Grenoble for the Adhoc and the Spoken Consumer Health search. Our focus for this participation is to study the effectiveness of simple query expansions for health related retrieval. We focused on several query expansions, using knowledge-based or embedding-based techniques, with and without weighting of expansions, with and without Pseudo Relevance Feedback. The results obtained for Adhoc queries show that our baseline run out-performs the query expansions proposed. The results obtained for spoken queries show that several speakers lead to very different results, and that merging the results from several users improve the quality of the system.
