In this work, we present LengClaro2023, a dataset of legal-administrative texts in Spanish. Based on the most frequently used procedures from the Spanish Social Security website, we have created for each text two simplified equivalents. The first version follows the recommendations provided by arText claro. The second version incorporates additional recommendations from plain language guidelines to explore further potential improvements in the system. The linguistic resource created in this work can be used for evaluating automatic text simplification (ATS) systems in Spanish.

A large body of research on morphological paradigms makes the prediction that irregular morphological patterns of allomorphy are more likely to emerge and persist when they serve to mark important functional distinctions. More specifically, it has been observed that in some Germanic languages in which narrative past tense is expressed by the past participle, there is a greater affinity for stem allomorphy shared by preterite forms and past participles to the exclusion of present forms (the so-called ABB pattern), as it serves to enhance marking of the binary semantic opposition between present and past. Using data from 107 cognate verbs attested across 14 archaic and contemporary Germanic languages and a novel hierarchical phylogenetic model, we show that there is a greater long-term preference for this alternation pattern in situations where narrative past tense has been extended to the past participle, confirming this hypothesis. We further elucidate the mechanisms underlying this association, demonstrating that this association holds because verbs with the ABB pattern are more likely to preserve it in situations where it marks an important binary semantic opposition; however, there is less evidence that the ABB pattern is extended to verbs with different patterns under the same circumstances. These results bear on debate as to whether the distribution of irregularity we observe cross-linguistically is due primarily to (1) the preservation of irregular patterns or (2) an active drive toward irregularization in certain contexts, and are more in line with the first hypothesis.

This study presents the ``Arabic Derivational ChainBank,'' a novel framework for modeling Arabic derivational morphology. It establishes connections between forms and meanings by constructing a chain of derived words that reflect their derivational significance. To expedite the process, a rule-based methodology was employed, avoiding time-consuming manual annotation. The derivational network was then aligned with the CamelMorph morphological analyzer database. This two-step process resulted in a chain of derived word lemmas linked to their roots, encompassing 23,333 evaluated derivational relations, thereby demonstrating the efficiency of the ChainBank.

English allows for both compounds (e.g., London-made) and phrasal paraphrases (e.g., made in London). While these constructions have roughly the same truth-conditional meaning, we hypothesize that the compound allows less freedom to express the nature of the semantic relationship between the participle and the pre-participle nominal. We thus predict that the pre-participle slot is more constrained than the equivalent position in the phrasal construction. We test this prediction in a large corpus by measuring the entropy of corresponding nominal slots, conditional on the participle used. That is, we compare the entropy of $\alpha$ in compound construction slots like $\alpha$-[V]ed to the entropy of $\alpha$ in phrasal constructions like [V]ed by $\alpha$ for a given verb V. As predicted, there is significantly lower entropy in the compound construction than in the phrasal construction. We consider how these predictions follow from more general grammatical properties and processing factors.

This paper presents the development of an AI-based language learning platform Revita. It is a freely available intelligent online tutor, developed to support learners of multiple languages, from low-intermediate to advanced levels. It has been in pilot use by hundreds of students at several universities, whose feedback and needs are shaping the development. One of the main emerging features of Revita is the introduction of a system of linguistic constructs as the representation of domain knowledge. The system of constructs is developed in close collaboration with experts in language teaching. Constructs define the types of exercises, the content of the feedback, and enable the detailed modeling and evaluation of learning progress.

Computers only deal with numbers, and so to get a computer to analyse text data -- for example, to find topics, to translate, to summarise, etc -- you must first convert the data into numbers. A'word vector' is simply a set of numbers which represent a word: the computer's internal representation of that word. If we train a computer to predict the missing word from a sentence, giving it millions of examples to learn from, and we allow the computer to improve its predictions by changing the numbers allocated to each word, we find that synonyms end up being allocated numbers that are close to one another. There are lots of blog posts and tutorials out there which explain the mechanics behind the word vector training process. My aim below is to give an understanding of why the words end up in the places they do -- of why synonyms end up close together.

Data mining allows the exploration of sequences of phenomena, whereas one usually tends to focus on isolated phenomena or on the relation between two phenomena. It offers invaluable tools for theoretical analyses and exploration of the structure of sentences, texts, dialogues, and speech. We report here the results of an attempt at using it for inspecting sequences of verbs from French accounts of road accidents. This analysis comes from an original approach of unsupervised training allowing the discovery of the structure of sequential data. The entries of the analyzer were only made of the verbs appearing in the sentences. It provided a classification of the links between two successive verbs into four distinct clusters, allowing thus text segmentation. We give here an interpretation of these clusters by comparing the statistical distribution of independent semantic annotations.

In the general form, such a dependence can be formulated as follows: the longer is the construct the shorter are its constituents. Later on, this fact was put in a mathematical form by Gabriel Altmann [1]. Now it is known as the Menzerath-Altmann law and is considered to be one of the general linguistic laws with evidences reaching far beyond the linguistic domain itself [2]. The mentioned relationship is studied on various levels of language units, such as syllable-word, morpheme-word, etc. While the word-sentence seems to be the most straightforward generalization on the syntactic level, it appears that in fact an intermediate unit must be introduced in this scheme [3, p. 283]. Usually, this intermediate unit are thought to be phrases or clauses, which are direct constituents of the sentence [4]. We would like to note, however, that the notion of clause is not well elaborated in Eastern European linguistic traditions [5], including Ukrainian (cf.
