ALEE: Any-Language Evaluation of Embeddings via English-Centric Minimal Pairs

Andrianos Michail, Stylianos Psychias, Michelle Wastl +3

Text embeddings are standard for semantic similarity tasks, yet their evaluation remains an open challenge. Current benchmarks are static, cover only a limited set of languages, ar…

ICDAR 2026 HIPE-OCRepair Competition on LLM-Assisted OCR Post-Correction for Historical Documents

Maud Ehrmann, Emanuela Boros, Juri Opitz +3

We present the results of HIPE-OCRepair-2026, an ICDAR competition on LLM-assisted OCR post-correction of historical documents. OCR post-correction remains a long-standing challeng…

Overview of HIPE-2026: Person-Place Relation Extraction from Multilingual Historical Texts

Juri Opitz, Maud Ehrmann, Corina Raclé +3

Was this person ever at that place, and if so, when? Answering such questions from noisy, multilingual historical documents is the central challenge of HIPE-2026, the third edition…

Attention Calibration for Position-Fair Dense Retrieval

Andrianos Michail, Elias Schuhmacher, Juri Opitz +2

Dense retrieval compresses a passage into a single vector, but this compression is positionally skewed: early content dominates the embedding, and retrieval degrades when the relev…

CLEF HIPE-2026: Evaluating Accurate and Efficient Person-Place Relation Extraction from Multilingual Historical Texts

Juri Opitz, Corina Raclé, Emanuela Boros +4

HIPE-2026 is a CLEF evaluation lab dedicated to person-place relation extraction from noisy, multilingual historical texts. Building on the HIPE-2020 and HIPE-2022 campaigns, it ex…

Information Representation Fairness in Long-Document Embeddings: The Peculiar Interaction of Positional and Language Bias

Elias Schuhmacher, Andrianos Michail, Juri Opitz +2

To be discoverable in an embedding-based search process, each part of a document should be reflected in its embedding representation. To quantify any potential reflection biases, w…

Adapting Multilingual Embedding Models to Historical Luxembourgish

Andrianos Michail, Corina Julia Raclé, Juri Opitz +1

The growing volume of digitized historical texts requires effective semantic search using text embeddings. However, pre-trained multilingual models face challenges with historical…

Interpretable Text Embeddings and Text Similarity Explanation: A Survey

Juri Opitz, Lucas Möller, Andrianos Michail +2

Text embeddings are a fundamental component in many NLP tasks, including classification, regression, clustering, and semantic search. However, despite their ubiquitous application,…

Sentence Smith: Controllable Edits for Evaluating Text Embeddings

Hongji Li, Andrianos Michail, Reto Gubelmann +2

Controllable and transparent text generation has been a long-standing goal in NLP. Almost as long-standing is a general idea for addressing this challenge: Parsing text to a symbol…

MMTEB: Massive Multilingual Text Embedding Benchmark

Kenneth Enevoldsen, Isaac Chung, Imene Kerboua +83

Text embeddings are typically evaluated on a limited set of tasks, which are constrained by language, domain, and task diversity. To address these limitations and provide a more co…

Examining Multilingual Embedding Models Cross-Lingually Through LLM-Generated Adversarial Examples

Andrianos Michail, Simon Clematide, Rico Sennrich

The evaluation of cross-lingual semantic search models is often limited to existing datasets from tasks such as information retrieval and semantic textual similarity. We introduce…

PARAPHRASUS : A Comprehensive Benchmark for Evaluating Paraphrase Detection Models

Andrianos Michail, Simon Clematide, Juri Opitz

The task of determining whether two texts are paraphrases has long been a challenge in NLP. However, the prevailing notion of paraphrase is often quite simplistic, offering only a…

Automatic Generation and Evaluation of Reading Comprehension Test Items with Large Language Models

Andreas Säuberli, Simon Clematide

Reading comprehension tests are used in a variety of applications, reaching from education to assessing the comprehensibility of simplified texts. However, creating such tests manu…
