REDIT: A Tool and Dataset for Extraction of Personal Data in Documents of the Public Administration Domain

New regulations on transparency and the recent policy for privacy force the public administration (PA) to make their documents available, but also to limit the diffusion of personal data. The present work displays a first approach to the extraction of sensitive data from PA documents in terms of named entities and semantic relations among them, speeding up the process of extraction of these personal data in order to easily select those which need to be hidden. We also present the process of collection and annotation of the dataset

KIND: an Italian Multi-Domain Dataset for Named Entity Recognition

In this paper we present KIND, an Italian dataset for Named-entity recognition. It contains more than one million tokens with annotation covering three classes: person, location, and organization. The dataset (around 600K tokens) mostly contains manual gold annotations in three different domains (news, literature, and political discourses) and a semi-automatically annotated part. The multi-domain feature is the main strength of the present work, offering a resource which covers different styles and language uses, as well as the largest Italian NER dataset with manual gold annotations. It represents an important resource for the training of NER systems in Italian. Texts and annotations are freely downloadable from the Github repository

NERMuD at EVALITA 2023: Overview of the Named-Entities Recognition on Multi-Domain Documents Task

In this paper, we describe NERMuD, a Named-Entities Recognition (NER) shared task presented at the EVALITA 2023 evaluation campaign. NERMuD is organized into two different sub-tasks: a domain-agnostic classification and a domainspecific one. We display the evaluation of the system presented by the only task participant, ExtremITA. ExtremITA proposes a unified approach for all the tasks of EVALITA 2023, and it addresses in our case only the domain-agnostic sub-task. We present an updated version of KIND, the dataset distributed for the training of the system. We then provide the baselines proposed, the results of the evaluation, and a brief discussion

It Is MarkIT That Is New: An Italian Treebank of Marked Constructions

In this paper we present MarkIT, a treebank of marked constructions in Italian, containing around 800 sentences with dependency annotation. We detail the process to extract the sentences and manually correct them. The resource covers seven types of marked constructions plus some ambiguous sentences, whose syntax can be wrongly classified as marked. We also present a preliminary evaluation of parsing performance, comparing a model trained on existing Italian treebanks with the model obtained by adding MarkIT to the training set

Scent Mining: Extracting Olfactory Events, Smell Sources and Qualities

Olfaction is a rather understudied sense compared to the other senses. In NLP, however, there have been recent attempts to develop taxonomies and benchmarks specifically designed to capture smell-related information. In this work, we further extend this research line by presenting a supervised system for olfactory information extraction in English. We cast this problem as a token classification task and build a system that identifies smell words, smell sources and qualities. The classifier is then applied to a set of English historical corpora, covering different domains and written in a time period between the 15th and the 20th Century. A qualitative analysis of the extracted data shows that they can be used to infer interesting information about smelly items such as tea and tobacco from a diachronical perspective, supporting historical investigation with corpus-based evidence

Building a Multilingual Taxonomy of Olfactory Terms with Timestamps

Olfactory references play a crucial role in our memory and, more generally, in our experiences, since researchers have shown that smell is the sense that is most directly connected with emotions. Nevertheless, only few works in NLP have tried to capture this sensory dimension from a computational perspective. One of the main challenges is the lack of a systematic and consistent taxonomy of olfactory information, where concepts are organised also in a multi-lingual perspective. WordNet represents a valuable starting point in this direction, which can be semi-automatically extended taking advantage of Google n-grams and of existing language models. In this work we describe the process that has led to the semi-automatic development of a taxonomy for olfactory information in four languages (English, French, German and Italian), detailing the different steps and the intermediate evaluations. Along with being multi-lingual, the taxonomy also encloses temporal marks for olfactory terms thus making it a valuable resource for historical content analysis. The resource has been released and is freely available

Multimodal and Multilingual Understanding of Smells using VilBERT and mUNITER

We evaluate state-of-the-art multimodal models to detect common olfactory references in multilingual text and images in the scope of the Multimodal Understanding of Smells in Texts and Images (MUSTI) at Mediaeval’22. The goal of the MUSTI Subtask 1 is to classify paired text and images as to whether they refer to the same smell source or not. We approach this task as a Visual Entailment problem and evaluate the performance of the English model ViLBERT and the multilingual model mUNITER on MUSTI Subtask 1. Although base VilBERT and mUNITER models perform worse than a dummy baseline, fine-tuning these models improve performance significantly in almost all scenarios. We find that fine-tuning mUNITER with SNLI-VE and MUSTI train data performs better than other configurations we implemented. Our experiments demonstrate that the task presents some challenges, but it is by no means impossible. Our code is available on https://github. com/Odeuropa/musti-eval-baselines

MUSTI-Multimodal Understanding of Smells in Texts and Images at MediaEval 2022

MUSTI aims to collect information about smell from digital text and image collections from the 17th to 20th century in a multilingual setting. More precisely, MUSTI studies the relatedness of evocation of smells (smell sources being identified, objects being detected, gestures being mentioned or recognized) between texts and images. The main task is a binary classification task and entails identifying whether a pair of image and a text snippet contains the same smell source independent of what is the smell source. An optional sub-task is the determination of the smell sources that make the respective pair related

A Multilingual Benchmark to Capture Olfactory Situations over Time

We present a benchmark in six European languages containing manually annotated information about olfactory situations and events following a FrameNet-like approach. The documents selection covers ten domains of interest to cultural historians in the olfactory domain and includes texts published between 1620 to 1920, allowing a diachronic analysis of smell descriptions. With this work, we aim to foster the development of olfactory information extraction approaches as well as the analysis of changes in smell descriptions over time
