La Web semántica y las tecnologías del lenguaje humano

The implementation of semantic web address the current represents a paradigm shift, as it has to be passed from a web-based and natural language created in a structured and organized web, where content will be semantically labeled the main element. This will represent a new philosophy and way of working, as the development and creation of content for this website require a great deal of effort. This is the point where they can speak human language technologies to provide mechanisms and tools to assist the implementation and expansion of this new paradigm

A grammar for interpreting geo-analytical questions as concept transformations

Geographic Question Answering (GeoQA) systems can automatically answer questions phrased in natural language. Potentially this may enable data analysts to make use of geographic information without requiring any GIS skills. However, going beyond the retrieval of existing geographic facts on particular places remains a challenge. Current systems usually cannot handle geo-analytical questions that require GIS analysis procedures to arrive at answers. To enable geo-analytical QA, GeoQA systems need to interpret questions in terms of a transformation that can be implemented in a GIS workflow. To this end, we propose a novel approach to question parsing that interprets questions in terms of core concepts of spatial information and their functional roles in context-free grammar. The core concepts help model spatial information in questions independently from implementation formats, and their functional roles indicate how concepts are transformed and used in a workflow. Using our parser, geo-analytical questions can be converted into expressions of concept transformations corresponding to abstract GIS workflows. We developed our approach on a corpus of 309 GIS-related questions and tested it on an independent source of 134 test questions including workflows. The evaluation results show high precision and recall on a gold standard of concept transformations

A Controlled natural language layer for the semantic web

In this paper, I will show how a controlled natural language can be used to describe knowledge for the Semantic Web and discuss the formal properties of this language. At the first glance, the proposed controlled natural language looks like full English and can therefore be easily written and understood by non-specialists. However, its built-in grammatical and lexical restrictions, which are enforced by an intelligent authoring tool, guarantee that the language can be directly translated into description logic programs, i.e. the intersection of an expressive description logic with function-free logic programs. The controlled natural language can be used to make assertional and terminological statements as well as to specify rules for reasoning with the resulting assertional and terminological knowledge.10 page(s
