TTLab at Daleel 2026: STAR-Ar, Sequence Tagging for Argument Recognition in Arabic
Bhuvanesh Verma, Ali Abusaleh, Alexander Mehler
Argument Mining (AM) is a critical NLP task that remains significantly under-resourced in Arabic. This paper presents $\testtt{STAR-Ar}$, a BERT-BiLSTM-CRF architecture for argumen…
TTLab at StanceEval-2026: A Cloze-Style Prompting Approach for Arabic-Language Stance Detection (CLASP-Ar)
Bhuvanesh Verma, Ali Abusaleh, Alexander Mehler
Arabic-language stance detection remains challenging, and previous shared-task systems have largely relied on multitask learning and ensembles. While these systems achieve state-of…
TTLab at AlexandriaX-2026: A Fine-Tuned Surface Tagger for Arabic Machine-Translation Error-Span Detection and Classification
Ali Abusaleh, Bhuvanesh Verma, Alexander Mehler
We present TTLab's submission to the AlexandriaX-2026 Subtask~3 on Arabic MT error span detection and classification. Our system frames the task as token-level classification over…
From Retrieval to Weights: Parametric Individualization of Small Language Models with Individual Text Corpora
Christoph Wigbels, Ali Abusaleh, Markus T. Jansen +2
We approach a cognitive simulation perspective on episodic and semantic memory in multiple-choice question answering by incorporating text from individual text corpora (ITC) into r…
Individual Text Corpora Predict User-Specific Knowledge: Benchmarks of Individualized Knowledge Simulation
Christoph Wigbels, Ali Abusaleh, Markus T. Jansen +3
This study examines whether individual text corpora (ICs) from search histories can be used to simulate individual knowledge. We collected ICs from 316 adults, who answered 36 mult…
Learning to Detect Cross-Modal Negation: An Analysis of Latent Representations and an Attention-Based Solution
Ali AbuSaleh, Leon Hammerla, Alexander Mehler
Detecting high-level semantic concepts like negation across modalities remains a challenge for current multimodal systems. We analyze this as a fundamental representation learning…
MMTM: Tri-Modal Topic Modeling for Long-Form Video via Similarity-Gated Fusion
Ali Abusaleh, Bhuvanesh Verma, Alexander Mehler
We introduce MMTM, a modular pipeline for topic discovery in long-form video that integrates speech recognition, audio and visual embeddings, and BERTopic clustering through a dete…
Extending a Parliamentary Corpus with MPs' Tweets: Automatic Annotation and Evaluation Using MultiParTweet
Mevlüt Bagci, Ali Abusaleh, Daniel Baumartz +3
Social media serves as a critical medium in modern politics because it both reflects politicians' ideologies and facilitates communication with younger generations. We present Mult…
A Multitask VAE for Time Series Preprocessing and Prediction of Blood Glucose Level
Ali AbuSaleh, Mehdi Rahim
Data preprocessing is a critical part of time series data analysis. Data from connected medical devices often have missing or abnormal values during acquisition. Handling such situ…
