Probing BERT for Ranking Abilities
No full textContextual models like BERT are highly effective in numerous text-ranking tasks. However, it is still unclear as to whether contextual models understand well-established notions of relevance that are central to IR. In this paper, we use probing, a recent approach used to analyze language models, to investigate the ranking abilities of BERT-based rankers. Most of the probing literature has focussed on linguistic and knowledge-aware capabilities of models or axiomatic analysis of ranking models. In this paper, we fill an important gap in the information retrieval literature by conducting a layer-wise probing analysis using four probes based on lexical matching, semantic similarity as well as linguistic properties like coreference resolution and named entity recognition. Our experiments show an interesting trend that BERT-rankers better encode ranking abilities at intermediate layers. Based on our observations, we train a ranking model by augmenting the ranking data with the probe data to show initial yet consistent performance improvements (The code is available at https://github.com/yolomeus/probing-search/ ).Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Web Information System
BERT Rankers are Brittle: A Study using Adversarial Document Perturbations
No full textContextual ranking models based on BERT are now well established for a wide range of passage and document ranking tasks. However, the robustness of BERT-based ranking models under adversarial inputs is under-explored. In this paper, we argue that BERT-rankers are not immune to adversarial attacks targeting retrieved documents given a query. Firstly, we propose algorithms for adversarial perturbation of both highly relevant and non-relevant documents using gradient-based optimization methods. The aim of our algorithms is to add/replace a small number of tokens to a highly relevant or non-relevant document to cause a large rank demotion or promotion. Our experiments show that a small number of tokens can already result in a large change in the rank of a document. Moreover, we find that BERT-rankers heavily rely on the document start/head for relevance prediction, making the initial part of the document more susceptible to adversarial attacks. More interestingly, we find a small set of recurring adversarial words that when added to documents result in successful rank demotion/promotion of any relevant/non-relevant document respectively. Finally, our adversarial tokens also show particular topic preferences within and across datasets, exposing potential biases from BERT pre-training or downstream datasets.

Análise filogeográfica entre populações de Araucaria angustifolia (Bert.) O. Kuntze em sua área de distribuição natural
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias. Programa de Pós-Graduação em Recursos Genéticos VegetaisO Pinheiro Brasileiro (Araucaria angustifolia (Bert.) O. Kuntze), é uma das quatro coníferas nativas do Brasil, e a mais ameaçada após décadas de exploração massiva. Estudos filogeográficos ajudam a esclarecer aspectos espaciais e temporais da dispersão pós-glacial de diversas espécies vegetais. Neste trabalho foram caracterizadas as relações filogeográficas utilizando a variação nas sequências de DNA cloroplastidial (cpDNA) de três espaçadores intergênicos (trnD-trnT, psbC-trnS e trnS-trnfM) em 510 indivíduos de 34 populações de Araucaria angustifolia com ocorrência nos estados de São Paulo, Minas Gerais, Paraná, Santa Catarina, Rio Grande do Sul e no município de San Pedro, Argentina. Dezesseis haplótipos foram detectados na análise de 2.508 pb das sequências não codificantes. Os índices de diversidade genética foram h=0,823 e ?=0,00068. Foi encontrada média diferenciação genética dentro da maioria das populações (Fst 0,269) e alta diferenciação genética entre as populações mais distanciadas geograficamente (Fst 0,431). A rede de haplótipos e a distribuição geográfica dos haplótipos mostraram a formação de três grupos filogeográficos (GS- Grupo Sul, GC- Grupo Centro e GN- Grupo norte), sugerindo preliminarmente a existência passada de três refúgios glaciais. Entre os grupos GS e GC foi observada a existência de uma zona secundária de mistura. O padrão encontrado de divergência genética se encaixa na categoria filogeográfica I de Avise, na qual a separação espacial provocou uma descontinuidade na distribuição dos haplótipos. Estes resultados preliminares sugerem que a partir do Holoceno mediano (4.320 A.P.), as populações de Araucaria angustifolia se expandiram dos possíveis refúgios até os limites geográficos atualmente conhecidos. Portanto, estas informações fornecerão subsídios para o planejamento mais adequado das ações para a conservação desta espécie
Forged-GAN-BERT: Authorship Attribution for LLM-Generated Forged Novels
No full textThe advancement of generative Large Language Models (LLMs), capable of producing human-like texts, introduces challenges related to the authenticity of the text documents. This requires exploring potential forgery scenarios within the context of authorship attribution, especially in the literary domain. Particularly, two aspects of doubted authorship may arise in novels, as a novel may be imposed by a renowned author or include a copied writing style of a well-known novel. To address these concerns, we introduce Forged-GAN-BERT, a modified GAN-BERT-based model to improve the classification of forged novels in two data-augmentation aspects: via the Forged Novels Generator (i.e., ChatGPT) and the generator in GAN. Compared to other transformer-based models, the proposed Forged-GAN-BERT model demonstrates an improved performance with F1 scores of 0.97 and 0.71 for identifying forged novels in single-author and multi-author classification settings. Additionally, we explore different prompt categories for generating the forged novels to analyse the quality of the generated texts using different similarity distance measures , including ROUGE-1, Jaccard Similarity, Overlap Confident, and Cosine Similarity

In de voetsporen van de voorouders: steen na steen. Karma, trangenerationele overdracht en zingeving bij familieopstellingen
No full textIn deze scriptie onderzoekt Christel Jansen hoe het begrip karma wordt gebruikt in theorieën over transgenerationele overdracht (in de vorm van familietrauma’s). Zij bekijkt hoe het idee over karma zich door de tijd heen ontwikkelde: vanaf het hindoeïsme, boeddhisme en jaïnisme tot aan de oprichtster van de theosofische beweging, madame Blavatsky. Laatstgenoemde introduceerde het begrip familiekarma. Een term die een eigen leven is gaan leiden en in huidige spirituele bewegingen wordt gehanteerd. Hoe worden termen als karma en familiekarma gebruikt binnen deze groeperingen? Jansen onderzoekt dit aan de hand van een casestudie – familieopstellingen volgens de methode van Bert Hellinger – en bekijkt of karma een zingevende factor kan zijn bij het omgaan met overgedragen familietrauma’s
