Remedies against the Vocabulary Gap in Information Retrieval
Christophe Van Gysel
Search engines rely heavily on term-based approaches that represent queries and documents as bags of words. Text---a document or a query---is represented by a bag of its words that…
Reply With: Proactive Recommendation of Email Attachments
Christophe Van Gysel, Bhaskar Mitra, Matteo Venanzi +4
Email responses often contain items-such as a file or a hyperlink to an external document-that are attached to or included inline in the body of the message. Analysis of an enterpr…
Neural Vector Spaces for Unsupervised Information Retrieval
Christophe Van Gysel, Maarten de Rijke, Evangelos Kanoulas
We propose the Neural Vector Space Model (NVSM), a method that learns representations of documents in an unsupervised manner for news article retrieval. In the NVSM paradigm, we le…
Structural Regularities in Text-based Entity Vector Spaces
Christophe Van Gysel, Maarten de Rijke, Evangelos Kanoulas
Entity retrieval is the task of finding entities such as people or products in response to a query, based solely on the textual documents they are associated with. Recent semantic…
Semantic Entity Retrieval Toolkit
Christophe Van Gysel, Maarten de Rijke, Evangelos Kanoulas
Unsupervised learning of low-dimensional, semantic representations of words and entities has recently gained attention. In this paper we describe the Semantic Entity Retrieval Tool…
Neural Networks for Information Retrieval
Tom Kenter, Alexey Borisov, Christophe Van Gysel +3
Machine learning plays a role in many aspects of modern IR systems, and deep learning is applied in all of them. The fast pace of modern-day research has given rise to many differe…
Pyndri: a Python Interface to the Indri Search Engine
Christophe Van Gysel, Evangelos Kanoulas, Maarten de Rijke
We introduce pyndri, a Python interface to the Indri search engine. Pyndri allows to access Indri indexes from Python at two levels: (1) dictionary and tokenized document collectio…
