Our proposal consists of using a classical feature of bag-of-words, the TF-IDF model; and an emergent feature, obtained from processing word embeddings. The TF-IDF is used to relate texts which share words. Word embeddings are known by capture the syntax and semantics of a word. Following Mikolov et al. (2013), the sum of embedding vectors can model the meaning of a sentence. Using both features, we are able to capture the words shared between sentences and their semantics. We use linear regression to solve this problem, once the dataset is labeled as real numbers between 1 and 5. Our results are promising. Although the usage of embeddings has not overcome our baseline system, when we combined it with TF-IDF, our system achieved better results than only using TF-IDF. Our results achieved the first collocation of ASSIN 2016 for sentence similarity shared-task applied on brazilian portuguese sentences and second collocation when applying to Portugal portuguese sentences.","PeriodicalId":41819,"journal":{"name":"Linguamatica","volume":"29 1","pages":"59-64"},"PeriodicalIF":0.6,"publicationDate":"2016-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68372457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several variables and external criteria are usually followed when building a corpus but little is been said about textual distributional similarity in this context and the quality that it brings to research. In an attempt to fulfil this gap, this paper aims at presenting a simple but efficient methodology capable of measuring a corpus internal degree of relatedness. To do so, this methodology takes advantage of both available natural language processing technology and statistical methods in a successful attempt to access the relatedness degree between documents. Our findings prove that using a list of common entities and a set of distributional similarity measures is enough not only to describe and assess the degree of relatedness between the documents in a comparable corpus, but also to rank them according to their degree of relatedness within the corpus.","PeriodicalId":41819,"journal":{"name":"Linguamatica","volume":"8 1","pages":"3-19"},"PeriodicalIF":0.6,"publicationDate":"2016-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68371888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La versatilidad del ASinEs permite tambien el estudio de geolectos de otros estadios del espanol, asi como los de otras lenguas con las que esta actualmente en contacto. Todo ello proporciona una potente herramienta para la investigacion en el campo de la variacion de las lenguas romanicas y no romanicas (vasco, ingles, lenguas amerindias, etc.).El desarrollo de este proyecto cuenta con la colaboracion del Centre de Linguistica Teorica (Universitat Autonoma de Barcelona), el Centro IKER con sede en Bayona (Francia) y la Real Academia Espanola.

This project is groundbreaking, as there is no other atlas exclusively devoted to study the geolectal variation of geolectal variants of Spanish.

However, since word senses are complex entities, without well-defined boundaries, we suggest to handle them less artificially, by representing them as fuzzy objects, where each word has its membership degree, which can be related to the confidence on using the word to denote the concept conveyed by the synset. We thus propose an approach to discover synsets from a synonymy network, ideally redundant and extracted from several broad-coverage sources. The more synonymy relations there are between two words, the higher the confidence on the semantic equivalence of at least one of their senses. The proposed approach was applied to a network extracted from three Portuguese dictionaries and resulted in a large set of fuzzy synsets. Besides describing this approach and illustrating its results, we rely on three evaluations — comparison against a handcrafted Portuguese thesaurus; comparison against the results of a previous approach with a similar goal; and manual evaluation — to believe that our outcomes are positive and that, in the future, they might my expanded by exploring additional synonymy sources portuguesNuma wordnet, conceitos sao representados atraves de grupos de palavras, vulgarmente chamados de synsets, e cada pertenca de uma palavra a um synset representa um diferente sentido dessa mesma palavra.

Propomos entao uma abordagem automatica para descobrir um conjunto de synsets difusos a partir de uma rede de sinonimos, idealmente redundante, por ser extraida a partir de varias fontes, e o mais abrangentes possivel. Um dos principios e que, em quantos mais recursos duas palavras forem consideradas sinonimos, maior confianca havera na equivalencia de pelo menos um dos seus sentidos. A abordagem proposta foi aplicada a uma rede extraida a partir de tres dicionarios do portugues e resultou num novo conjunto de synsets para esta lingua, em que as palavras tem pertencas difusas, ou seja, fuzzy synsets. Para alem de apresentar a abordagem e a ilustrar com alguns resultados obtidos, baseamo-nos em tres avaliacoes — comparacao com um tesauro criado manualmente para o portugues; comparacao com uma abordagem anterior com o mesmo objetivo; e avaliacao manual — para confirmar que os resultados sao positivos, e poderao no futuro ser expandidos atraves da exploracao de outras fontes de sinonimos.","PeriodicalId":41819,"journal":{"name":"Linguamatica","volume":"7 1","pages":"3-17"},"PeriodicalIF":0.6,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68372028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
