Neague, P.M. (author), Gregoriadis, M.I. (author), Pouwelse, J.A. (author)This study introduces De-DSI, a novel framework that fuses large language models (LLMs) with genuine decentralization for information retrieval, particularly employing the differentiable search index (DSI) concept in a decentralized setting. Focused on efficiently connecting novel user queries with document identifiers without direct document...conference paper 2024

Pera, M.S. (author), Cena, Federica (author), Huibers, Theo (author), Landoni, Monica (author), Mauro, Noemi (author), Murgia, Emiliana (author)Information Retrieval (IR) remains an active, fast-paced area of research. However, most advances in IR have predominantly benefited the so-called “classical” users, e.g., English-speaking adults. We envision IR4U2as a forum to spotlight efforts that, while sparse, consider diverse, and often understudied, user groups when designing,...conference paper 2024

Zhu, P. (author), Wang, Zhen (author), Okumura, Manabu (author), Yang, J. (author)Textbook question answering is challenging as it aims to automatically answer various questions on textbook lessons with long text and complex diagrams, requiring reasoning across modalities. In this work, we propose MRHF, a novel framework that incorporates dense passage re-ranking and the mixture-of-experts architecture for TQA. MRHF...conference paper 2024

Landoni, Monica (author), Murgia, Emiliana (author), Huibers, Theo (author), Pera, M.S. (author)Informed by existing literature, in addition to lessons learned from ongoing research work pertaining to online information seeking, in this contribution, we discuss our view of how information pollution affects a critical yet understudied user group: children. We first highlight the need to take into account the unique characteristics of...journal article 2023

Panichella, A. (author), De Lucia, Andrea (author), Zaidman, A.E. (author)Trace ability recovery allows software engineers to understand the interconnections among software artefacts and, thus, it provides an important support to software maintenance activities. In the last decade, Information Retrieval (IR) has been widely adopted as core technology of semi-automatic tools to extract trace ability links between...conference paper 2015

Tao, K. (author)In the past decade, the Social Web has evolved into both an essential channel for people to exchange information and a new type of mass media. The immense amount of data produced presents new possibilities and challenges: algorithms and technologies need to be developed to extract and infer useful information from the Social Web. One of the main...doctoral thesis 2014

Eickhoff, C. (author)Information retrieval systems centrally build upon the concept of relevance in order to rank documents in response to a user's query. Assessing relevance is a non-trivial operation that can be influenced by a multitude of factors that go beyond mere topical overlap with the query. This thesis argues that relevance depends on personal (Chapter 2)...doctoral thesis 2014

Lormans, M. (author), Van Deursen, A. (author)Managing traceability data is an important aspect of the software development process. In this paper we define a methodology, consisting of six steps, for reconstructing requirements views using traceability data. One of the steps concerns the reconstruction of the traceability data. We investigate to what extent Latent Semantic Indexing (LSI),...report 2007
