Representing Verbal Semantics with Diagrams: An Adaptation of the UML for Lexical Semantics

The paper presents a new way of accounting for a diagrammatic notation based on the Unified Modeling Language (UML). We will introduce the new framework by outlining some modeling elements and indicating major differences to the UML. An extended example will be discussed in more detail. We will then focus on the cognitive background of the framework, and in particular address the question why the usage of graphical elements within a linguistic modeling language proves to be very fruitful. Finally, we will briefly indicate the potential of the newframework and its applicability

Swahili conditional constructions in embodied Frames of Reference: Modeling semantics, pragmatics, and context-sensitivity in UML mental spaces

Studies of several languages, including Swahili [swa], suggest that realis (actual, realizable) and irrealis (unlikely, counterfactual) meanings vary along a scale (e.g., 0.0–1.0). T-values (True, False) and P-values (probability) account for this pattern. However, logic cannot describe or explain (a) epistemic stances toward beliefs, (b) deontic and dynamic stances toward states-of-being and actions, and (c) context-sensitivity in conditional interpretations. (a)–(b) are deictic properties (positions, distance) of ‘embodied’ Frames of Reference (FoRs)—space-time loci in which agents perceive and from which they contextually act (Rohrer 2007a, b). I argue that the embodied FoR describes and explains (a)–(c) better than T-values and P-values alone. In this cognitive-functional-descriptive study, I represent these embodied FoRs using Unified Modeling LanguageTM (UML) mental spaces in analyzing Swahili conditional constructions to show how necessary, sufficient, and contributing conditions obtain on the embodied FoR networks level.Swahili, conditional constructions, UML, mental spaces, Frames of Reference, epistemic stance, deontic stance, dynamic stance, context-sensitivity, non-monotonic logi

Processamento de linguagem natural para indexação automática semântico-ontológica

Tese (doutorado)—Universidade de Brasília, Faculdade de Ciência da Informação, Programa de Pós-Graduação em Ciência da Informação, 2013.A pesquisa propõe uma arquitetura de indexação automática de documentos utilizando mecanismos de processamento de linguagem natural em nível semântico. Por meio do arranjo de ferramentas e recursos existentes, agregado ao desenvolvimento de software para integração, é construído um sistema de indexação automática que utiliza conhecimento modelado em uma ontologia para análise semântica. A aplicação da arquitetura é exemplificada e posta à prova em um conjunto de laudos periciais de crimes cibernéticos produzidos pela Perícia Criminal da Polícia Federal. Os resultados de pesquisa apontam para a melhoria que o aprofundamento à análise semântica do processamento de linguagem natural oferece para a seleção automática de descritores e, por extensão, para a recuperação da informação. Dentre as contribuições inéditas desta tese incluem-se a arquitetura de sistema de informação para indexação automática proposta, a ontologia construída para a análise semântica e as implementações em linguagem de programação Python. Por fim, o trabalho insere-se em uma área de pesquisa que tem sido cada vez mais investigada, no entanto ainda carece de resultados amadurecidos, qual seja o processamento de linguagem natural em língua portuguesa. __________________________________________________________________________ ABSTRACTThe research proposes an automatic indexing architecture of documents using natural language processing mechanisms on semantic level. By organizing existing tools and resources, added to software development for integration, an automatic indexing system which uses knowledge modeled by ontology to semantic analysis is built. The applicability of the architecture is exemplified and put into proof on forensics reports of cybercrimes produced by Federal Police Forensics Experts. The research results point to the benefits that semantic analysis on natural language processing offers to automatic descriptor selection and information retrieval. As contributions of this thesis there are the proposed automatic indexing information system architecture, the ontology built to semantic analysis and the implementations on Python programming language. Concluding, the work inserts itself in a research area that has been increasingly more investigated, however still demanding mature results, which is natural language processing on portuguese language
