Abstract

In the scientific digital libraries, some papers from different research communities can be described by community-dependent keywords even if they share a semantically similar topic. Articles that are not tagged with enough keyword variations are poorly indexed in any information retrieval system which limits potentially fruitful exchanges between scientific disciplines. In this paper, we introduce a novel experimentally designed pipeline for multi-label semantic-based tagging developed for open-access metadata digital libraries. The approach starts by learning from a standard scientific categorization and a sample of topic tagged articles to find semantically relevant articles and enrich its metadata accordingly. Our proposed pipeline aims to enable researchers reaching articles from various disciplines that tend to use different terminologies. It allows retrieving semantically relevant articles given a limited known variation of search terms. In addition to achieving an accuracy that is higher than an expanded query based method using a topic synonym set extracted from a semantic network, our experiments also show a higher computational scalability versus other comparable techniques. We created a new benchmark extracted from the open-access metadata of a scientific digital library and published it along with the experiment code to allow further research in the topic.

Abstract

In scientific text corpus, some articles from different research communities are not tagged by the same keywords even if they share the same topic. This causes issues in information retrieval systems using limited number of tag variations and thus, lower chances of interdisciplinary exploration. Our approach automatically assigns a topic tag to articles by learning a classifier for each topic based on the semantics representation of the title and the abstract of already tagged articles. The approach requires much less computation power than using topic modeling on millions of documents. In our proposed model, we use topic sysnomyns to retrieve more semantically similar articles and merge them to the articles obtained by the topic classifier. The experiments show higher recall against two variations of the model, one only uses the synonyms set, and another one only uses the semantic representation of the text., Dans les corpus de textes scientifiques, certains articles issus de communautés de chercheurs différentes peuvent ne pas être décrits par les mêmes mots-clés alors qu'ils partagent la même thématique. Ce phénomène cause des problèmes dans la recherche d'information, ces articles étant mal indexés, et limite les échanges potentiellement fructueux entre disciplines scientifiques. Notre modèle permet d'attribuer automatiquement une étiquette thématique aux articles au moyen d'un apprentissage des représentations sémantiques d'articles du corpus déjà étiquetés. Passant bien à l'échelle, cette méthode a pu être testée sur une bibliothèque numérique d'articles scientifiques comportant des millions de documents. Nous utilisons un réseau sémantique de synonymes pour extraire davantage d'articles sémantiquement similaires et nous les fusionnons avec ceux obtenus par un modèle de classement thématique. Cette méthode combinée présente de meilleurs taux de rappel que les versions utilisant soit le réseau sémantique seul, soit la seule représentation sémantique des textes.
