This article presents an ongoing research on one of the several native languages of the Americas: Amuzgo or jny’on3 nda3 . This language is spoken in Southern Mexico and belongs to the Otomanguean family. Although Amuzgo vitality is stable and there are some available resources, such as grammars, dictionaries, or literature, its digital inclusion is emerging (cf. Eberhard et al. (2024)). In this respect, here is described the creation of a curated dataset in Amuzgo. This resource is intended to contribute the development of tools for scarce resources languages by providing fine-grained linguistic information in different layers: From data collection with native speakers to data annotation. The dataset was built according to the following method: i) data collection in Amuzgo by means of linguistic fieldwork; ii) acoustic data processing; iii) data transcription; iv) glossing and translating data into Spanish; v) semiautomatic alignment of translations; and vi) data systematization. This resource is released as an open access dataset to foster the academic community to explore the richness of this language.

One of the remarkable characteristics of the drug lexicon is its elusive nature. In order to communicate information related to drugs or drug trafficking, the community uses several terms that are mostly unknown to regular people, or even to the authorities. For instance, the terms jolly green, joystick, or jive are used to refer to marijuana. The selection of such terms is not necessarily a random or senseless process, but a communicative strategy in which figurative language plays a relevant role. In this study, we describe an ongoing research to identify drug-related terms by applying machine learning techniques. To this end, a data set regarding drug trafficking in Spanish was built. This data set was used to train a word embedding model to identify terms used by the community to creatively refer to drugs and related matters. The initial findings show an interesting repository of terms created to consciously veil drug-related contents by using figurative language devices, such as metaphor or metonymy. These findings can provide preliminary evidence to be applied by law agencies in order to address actions against crime, drug transactions on the internet, illicit activities, or human trafficking.

Research on automatic humor recognition has developed several features which discriminate funny text from ordinary text. The features have been demonstrated to work well when classifying the funniness of single sentences up to entire blogs. In this paper we focus on evaluating a set of the best humor features reported in the literature over a corpus retrieved from the Slashdot Web site. The corpus is categorized in a community-driven process according to the following tags: funny, informative, insightful, offtopic, flamebait, interesting and troll. These kinds of comments can be found on almost every large Web site; therefore, they impose a new challenge to humor retrieval since they come along with unique characteristics compared to other text types. If funny comments were retrieved accurately, they would be of a great entertainment value for the visitors of a given Web page. Our objective, thus, is to distinguish between an implicit funny comment from a not funny one. Our experiments are preliminary but nonetheless large-scale: 600,000 Web comments. We evaluate the classification accuracy of naive Bayes classifiers, decision trees, and support vector machines. The results suggested interesting findings.
