- Conscious interfaces: a shared responsibility(IJISET, 2018-01) Ramírez Laureano, Emiliano; Laureano Cruces, Ana Lilia; Ledo Mezquita, Yoel; Flores Mendoza, Claudia; Universidad de las Américas; https://ror.org/03ayjn504The interfaces have gradually become important because they are a conjectural point to achieve antropoformization of the spaces used by humans. Under this perspective, it is essential to have a certain degree of intelligence that allows autonomy during decision-making. Now, the interfaces appear in our lives being able of certain intimacy; this implies an implicit knowledge; even if it is a general form of human behavior and its vulnerability to certain events. This article presents a first version of what is intended to be the inference engine of an interface for an autonomous car. The mental models that represent the conducts of the interface are designed, which will be responsible for the continuous monitoring of the environment. The interface will make a decision considering its affects, that is, what does the interface feel as a conscious part within a context, in the case of study driving a car. In order to achieve this, is used a methodology that allows to take into account the emotions within a cognitive model.
- Some linguistic methods of improving the quality of document retrieval on the internet(Inderscience Publishers, 2005-01) Gelbukh, Alexander; Sidorov, Grigori; Ledo Mezquita, Yoel; Instituto Politécnico Nacional y Chung-Ang University; https://ror.org/03ayjn504One of the problems of e-Business is to find relevant documents for making correct decisions. The main problem of the Internet is the huge amount of documents that makes it difficult to find the relevant ones, hence the importance of the methods allowing for improving the quality of document retrieval. We discuss some linguistic problems of document retrieval on the Internet related to the following natural language phenomena: (1) morphological processes: e.g., takes, took, taken are grammar forms of take, (2) polysemy and homonymy: most words have several senses, e.g., bank is a financial institution, shore, bench, etc., (3) non-linearity of syntactic relations: in case of a query that contains word combinations, the words forming a word combination can be separated by other words in the documents. Some linguistic-based methods and strategies related to the discussed problems are proposed that improve the quality of document retrieval or show the necessity of application of linguistic methods.
- On similarity of word senses in explanatory dictionaries(Bahri Publications, 2003-01) Gelbukh, Alexander; Sidorov, Grigori; Ledo Mezquita, Yoel; Instituto Politécnico Nacional; https://ror.org/059sp8j34; https://ror.org/03ayjn504Quality machine translation (MT) as well as of some other applications (such as information retrieval, IR) require word sense disambiguation (WSD) in the source text. However, WSD is only possible if the word senses specified in the dictionaries are really different and clearly distinguishable. We investigate the semantic closeness of different senses of the same word in a Spanish explanatory dictionary. We define the closeness between two senses as the relative number of equal or synonymous words in their definitions. We show that a considerable part of dictionary definitions (ca. 90%) are different enough to be distinguished in MT and IR. On the other hand, a considerable number of definitions (ca. 10%) are too similar to be reliably distinguished. These results suggest that MT and IR can take advantage of WSD algorithms, but for this, the similar senses reflecting too subtle meaning nuances should be clustered together to form coarser but easier distinguishable senses. The proposed method for detecting too similar senses can be incorporated into the lexicographer’s workbench to be used in development and improvement of dictionaries.
- Tool for computer-aided spanish word sense disambiguation(Springer-Verlag Berlin Heidelberg, 2003-01-01) Ledo Mezquita, Yoel; Sidorov, Grigori; Gelbukh, Alexander; Instituto Politécnico Nacional; https://ror.org/059sp8j34; https://ror.org/03ayjn504We present a system for for computer-aided WSD mark-up of texts in Spanish. The system is is based on Anaya dictionary, uses a Spanish morphological analyzer and a WSD method based on Lesk algorithm (along with the other standard strategies). This tool reduces time and effort for preparation WSD-marked corpora in Spanish. We also discuss the requirement for such type of systems, which our particular system satisfies only partially.
