Leveraging Lexical Resources and Constraint Grammar for Rule-Based Part-of-Speech Tagging in Welsh (L18-1)
Copied to clipboard
| Challenge: | POS tags are based on pre-annotated text, but there is not enough data to train a statistical POS tagger in lesser-resourced languages such as Welsh. |
| Approach: | They propose a rule-based POS tagger for Welsh based on the VISL Constraint Grammar parser and extract a list of possible POS tags for each word token in a running text. |
| Outcome: | The proposed approach is particularly useful in dealing with some of the specific intricacies of Welsh, such as morphological changes and word mutations. |

| Challenge: | Automatic semantic annotation of natural language data is an important task in Natural Language Processing. |
| Approach: | They develop a Welsh semantic annotation tool that can be used to analyze Welsh text . it uses Lancaster's USAS semantic classification scheme to tag words with semantic tags . |
| Outcome: | The proposed tool can cover up to 91.78% of words in Welsh text. |

| Challenge: | Using annotation variation principles, Part-of-Speech tagging performance degrades when applied to test sentences that depart from training data. |
| Approach: | They propose to use the annotation variation principle to identify inconsistencies between annotations . they also evaluate their impact on prediction performance . |
| Outcome: | The proposed method can detect errors in gold standard annotations and improve prediction performance. |
Distant Supervision from Disparate Sources for Low-Resource Part-of-Speech Tagging (D18-1)
Copied to clipboard
| Challenge: | Low-resource languages lack manual annotated data to learn basic models such as part-of-speech (POS) taggers. |
| Approach: | They propose a cross-lingual neural part-of-speech tagger that learns from disparate sources of distant supervision in a uniform framework. |
| Outcome: | The proposed model scales to hundreds of low-resource languages without access to gold annotated data. |
Machine Learning and Deep Neural Network-Based Lemmatization and Morphosyntactic Tagging for Serbian (2020.lrec-1)
Copied to clipboard
| Challenge: | The training of new tagger models for Serbian is motivated by the enhancement of the existing tagset with the grammatical category of a gender. |
| Approach: | They propose to use TreeTagger and spaCy taggers to train new Serbian tagger models and to align Serbian morphological dictionaries with the grammatical category of a gender. |
| Outcome: | The proposed models achieve 98% PoS-tagging precision per token, and the annotated dataset will be published. |
Domain adaptation for part-of-speech tagging of noisy user-generated text (N19-1)
Copied to clipboard
| Challenge: | Existing POS taggers for canonical German text achieve good results around 97% accuracy, but when applying these trained models to out-of-domain data the performance decreases drastically. |
| Approach: | They propose a neural network that trains an out-of-domain model on a large newswire corpus and transfers those weights by using them as a prior for a model trained on the target domain. |
| Outcome: | The proposed model achieves a tagging accuracy of slightly over 90%, improving on the previous state of the art for this task. |
What data should I include in my POS tagging training set? (2025.findings-emnlp)
Copied to clipboard
| Challenge: | POS tagging is a crucial task for descriptive linguistics and language documentation . POS tags are not available in all languages, but are used for training sets for understudied languages . |
| Approach: | They compare POS tagging with in-context learning, active learning, and random sampling . they find that POS can deliver reasonable results for communities with limited resources . |
| Outcome: | The proposed training set for Indigenous and endangered languages performs better than random sampling. |

A Grounded Unsupervised Universal Part-of-Speech Tagger for Low-Resource Languages (N19-1)
Copied to clipboard
| Challenge: | Unsupervised part of speech (POS) tagging is often framed as a clustering problem, but taggers need to ground their clusters as well. |
| Approach: | They propose an approach for low-resource unsupervised part of speech (POS) tagging that yields fully grounded output and requires no labeled training data. |
| Outcome: | The proposed method achieves reasonable performance across languages, including Sinhalese and Kinyarwanda, with no labeled training data. |
Toward a Lightweight Solution for Less-resourced Languages: Creating a POS Tagger for Alsatian Using Voluntary Crowdsourcing (L18-1)

| Challenge: | Using a crowdsourcing platform, we collected 18,917 annotations for a less-resourced French regional language, Alsatian. |
| Approach: | They developed a platform that allows people to gather part-of-speech annotations on a variety of corpora and train a first tagger specific to Alsatian. |
| Outcome: | The proposed method is valid for Alsatian and can be adapted to other languages. |
Graph Based Semi-Supervised Learning Approach for Tamil POS tagging (L18-1)
Copied to clipboard
| Challenge: | Parts of Speech (POS) tagging is challenging for low resourced languages such as Tamil . low resource Tamil does not have large POS annotated corpus to build good quality POS taggers using supervised machine learning techniques. |
| Approach: | They propose a graph-based semi-supervised learning approach to classify unlabelled data using a small POS labelled data set. |
| Outcome: | The proposed method achieves 0.8743 over 0.7333 produced by a CRF tagger for the same limited size corpus. |
