Latent semantic analysis for tagging activation states and identifiability in northwestern Mexican news outlets

The present work aims to study the relationship between measures, obtained from Latent Semantic Analysis (LSA) and a variant known as SPAN, and activation and identifiability states (Informative States) of referents in noun phrases present in journalistic notes from Northwestern Mexican news outlets written in Spanish. The aim and challenge is to find a strategy to achieve labelling of new / given information in the discourse rooted in a theoretically linguistic stance. The new / given distinction can be defined from different perspectives in which it varies what linguistic forms are taken into account. Thus, the focus in this work is to work with full referential devices (n = 2 388). Pearson’s R correlation tests, analysis of variance, graphical exploration of the clustering of labels, and a classification experiment with random forests are performed. For the experiment, two groups were used: noun phrases labeled with all 10 tags of informative states and a binary labelling, as well as the use of two bags-of-words for each noun phrase: the interior and the exterior. It was found that using LSA in conjunction with the inner bag of words can be used to classify certain informational states. This same measure showed good results for the binary division, detecting which sentences introduce new referents in discourse. In previous work using a similar method in noun phrases in English, 80% accuracy (n = 478) was reached in their classification exercise. Our best test for Spanish reached 79%. No work on Spanish using this method has been done before and this kind of experiment is important because Spanish exhibits a more complex inflectional morphology.

“Stelele și lalelele”: saggio di micromonografia storico descrittiva di una classe flessiva della lingua romena (II)

“Stelele și lalelele”: Micromonography of an Inflectional Class in the Romanian Language (II). This article is part of a series aimed at reconstructing the history, and discussing the current state of what has been considered, from a Romance perspective, a peculiarity of Romanian language: the existence of an inflectional class of feminine nouns ending in tonic vowel (in short: F√V́ Ø), which form the plural with the addition of the le morpheme. The present paper, the second in the series, discusses some morphological traits of F√V́ Ø on the basis of a lexicographical corpus of contemporary standard Romanian: division in subclasses, internal morphological structure of its members (primitive and derivatives nouns, in particular diminutives, internal formations), and morphological variability. Keywords: nominal morphology, Romance plural, Romanian language, Turkish loanwords, inflectional morphology.

Arabic Learners’ Production of Regular English Past Tense Verbs

Previous studies show that second language (L2) learners of English sometimes produce the verb with proper past tense inflectional morphology as in help[t] and sometimes repair the cluster, as in helpø or hel[pəd]. Complicating matters, these studies focused on L2 learners whose native languages disallowed codas or had very restricted codas. Thus, it is difficult to tell whether any problems in producing past tense morphology are due to first language L1-transferred coda restrictions, or an inability to acquire the abstract feature of past tense. To rule out native language syllable structure interference, this paper aims to examine the production of the English regular past tense verb by Arabic L1 ESL learners, a language that allows complex codas. The paper also examines the role of a phonological universal, the Obligatory Contour Principle (OCP) that disallows two adjacent similar sounds, and its effect on learners’ production. The data come from twenty-two English as a Second Language (ESL) students at three levels of proficiency. The task was a sentence list eliciting target clusters in past tense contexts that violate manner in OCP: fricative + stop ([st], [ft]) vs. stop + stop ([pt], [kt]). Results show that L1 Arabic speakers have difficulty in producing past tense morphology, even though their L1 allows complex codas. Fricative + stop clusters are repaired (epenthesis/deletion) at a lower rate (low =25.71%, intermediate = 6.6%, high=11.11%) than stop + stop clusters (low=57.14%, intermediate = 40.27%, high=22.91%). The higher rate of repair is clear in stops + stop clusters suggesting that learners abide by phonological universals and prefer not to violate OCP. Finally, proficiency level has an effect on target-like production, as higher-proficiency learners produce past-tense morphology at a higher rate than lower-proficiency learners. Together, these results indicate that L1 transfer is not the only source of difficulty in the production of past tense morphology, and that the abstract feature of tense is problematic, particularly at the early stages of ESL development.

Does morphological complexity affect word segmentation? Evidence from computational modeling

How can infants detect where words or morphemes start and end in the continuous stream of speech? Previous computational studies have investigated this question mainly for English, where morpheme and word boundaries are often isomorphic. Yet in many languages, words are often multimorphemic, such that word and morpheme boundaries do not align. Our study employed corpora of two languages that differ in the complexity of inflectional morphology, Chintang (Sino-Tibetan) and Japanese (in Experiment 1), as well as corpora of artificial languages ranging in morphological complexity, as measured by the ratio and distribution of morphemes per word (in Experiments 2 and 3). We used two baselines and three conceptually diverse word segmentation algorithms, two of which rely purely on sublexical information using distributional cues, and one that builds a lexicon. The algorithms’ performance was evaluated on both word- and morpheme-level representations of the corpora.Segmentation results were better for the morphologically simpler languages than for the morphologically more complex languages, in line with the hypothesis that languages with greater inflectional complexity could be more difficult to segment into words. We further show that the effect of morphological complexity is relatively small, compared to that of algorithm and evaluation level. We therefore recommend that infant researchers look for signatures of the different segmentation algorithms and strategies, before looking for differences in infant segmentation landmarks across languages varying in complexity.

Morphological generalization in heritage speakers: The Turkish aorist

Heritage speakers (HS) have been shown to experience difficulties with inflectional morphology (particularly with irregular morphology) and to frequently overapply regular morphology. The present study seeks to get further insight into the inflectional processes of HS by investigating how these are generalized to nonce words in language production, the first study of this kind for heritage Turkish. We specifically examined morphological generalization processes in the Turkish aorist which – unusual for this language – includes both regular and irregular forms. A written elicited-production experiment containing nonce verbs with varying degrees of similarity to existing verbs was administered to Turkish HS and native monolingually-raised Turkish speakers (MS). We also explored how well a formal model that was trained on a large lexical corpus of Turkish matches the human speakers’ performance. Our main finding is that HS employ both similarity-based and rule-based mechanisms for morphological generalization of the Turkish aorist, with subtle differences to the way these mechanisms are applied by Turkish MS.

Asymmetric Morphological Priming Among Inflected and Derived Verbs and Nouns in Greek

The present study examined differences between inflectional and derivational morphology using Greek nouns and verbs with masked priming (with both short and long stimulus onset asynchrony) and long-lag priming. A lexical decision task to inflected noun and verb targets was used to test whether their processing is differentially facilitated by prior presentation of their stem in words of the same grammatical class (inflectional morphology) or of a different grammatical class (derivational morphology). Differences in semantics, syntactic information, and morphological complexity between inflected and derived word pairs (both nouns and verbs) were minimized by unusually tight control of stimuli as permitted by Greek morphology. Results showed that morphological relations affected processing of morphologically complex Greek words (nouns and verbs) across prime durations (50–250ms) as well as when items intervened between primes and targets. In two of the four experiments (Experiments 1 and 3), inflectionally related primes produced significantly greater effects than derivationally related primes suggesting differences in processing inflectional versus derivational morphological relations, which may disappear when processing is less dependent on semantic effects (Experiment 4). Priming effects differed for verb vs. noun targets with long SOA priming (Experiment 3), consistent with processing differences between complex words of different grammatical class (nouns and verbs) when semantic effects are maximized. Taken together, results demonstrate that inflectional and derivational relations differentially affect processing complex words of different grammatical class (nouns and verbs). This finding indicates that distinctions of morphological relation (inflectional vs. derivational) are not of the same kind as distinctions of grammatical class (nouns vs. verbs). Asymmetric differences among inflected and derived verbs and nouns seem to depend on semantic effects and/or processing demands modulating priming effects very early in lexical processing of morphologically complex written words, consistent with models of lexical processing positing early access to morphological structure and early influence of semantics.

Modeling Morphology With Linear Discriminative Learning: Considerations and Design Choices

This study addresses a series of methodological questions that arise when modeling inflectional morphology with Linear Discriminative Learning. Taking the semi-productive German noun system as example, we illustrate how decisions made about the representation of form and meaning influence model performance. We clarify that for modeling frequency effects in learning, it is essential to make use of incremental learning rather than the end-state of learning. We also discuss how the model can be set up to approximate the learning of inflected words in context. In addition, we illustrate how in this approach the wug task can be modeled. The model provides an excellent memory for known words, but appropriately shows more limited performance for unseen data, in line with the semi-productivity of German noun inflection and generalization performance of native German speakers.

The Role of Linguistic Typology, Target Language Proficiency and Prototypes in Learning Aspectual Contrasts in Italian as Additional Language

The study examines how prototypes and typological relationships between the L1, the L2 and the target language (TL) interact with TL proficiency in learning Italian as additional language. Low-proficiency and high-proficiency undergraduate learners of Italian (N = 25) with Swedish as L1 performed an oral retelling story test, aiming to elicit the Italian aspectual contrast perfective-imperfective. Their tense selection was analyzed considering the predicates’ lexical aspect and the learners’ knowledge of a Romance L2, or lack thereof. The findings show that the typological proximity between the L2 and the TL exerts a differential role depending on TL proficiency. Initially, it is beneficial for accelerating the overall emergence of the imperfetto as an aspectual marker. However, the prototype factor and, more specifically, the predicates’ dynamicity influences the selection of past inflectional morphology. At more advanced stages, knowledge of a Romance language helps learners move beyond prototypical associations with the passato prossimo, but it does not seem to influence the use of the imperfetto among high-proficiency learners. These results are discussed in the light of research on the second and additional language learning of aspectual contrasts in Romance languages.

English Adjectives and Estonian Nouns: Looking for Agreement?

This study investigated how speakers of Estonian as L1 with varying degree of proficiency in English judge grammaticality of bilingual constructions English adjective + Estonian noun from the point of view of adjective agreement. Estonian is rich in inflectional morphology, and adjectives agree with nouns in case and number. The empirical evidence from English-Estonian bilingual speech shows that agreement is not always the case even when an English adjective fits into Estonian declension system. It is hypothesized that the higher proficiency in/exposure to English is, the higher is the acceptability of bilingual adjective phrases, and (non-)agreement does not play a role. To test this, an experiment was designed where the test corpus of 108 sentences consisted of real and constructed examples, both in agreement and non-agreement condition. Real sentences came from fashion and beauty blogs and vlogs. The test was administered online and the participants were asked to rate adjective acceptability. The hypothesis was confirmed: increased proficiency in English, together with younger age, had a positive correlation with acceptability of all adjective types, independent of adjective (non-)agreement. Residence and birthplace had a small effect on acceptability of some adjective types. Whether sentences were real or constructed, had only a minor effect. Male participants tended to assess real sentences lower, probably because of the topics typical for female blogs. Monosyllabic consonant-ending adjectives were exceptional, as their assessment did not depend on any factor. All in all, the study demonstrated that grammaticality judgment among the native speakers of the same L1 differs because of different degrees of bilingualism, and structural factors, such as compatibility with Estonian declension system, are not decisive. Thus, it is not clear what an ideal native speaker is.
