dc.description.abstractThe web is a giant resource of data and information about security, health, education, and others, matters that have great utility for people, but to get a synthesis or abstract about one or many documents is an expensive labor, which with manual process might be impossible due to the huge amount of data. Abstract generation is a challenging task, due to that involves analysis and comprehension of the written text in non structural natural language dependent of a context and it must describe an events synthesis or knowledge in a simple form, becoming natural for any reader. There are diverse approaches to summarize. These categorized into extractive or abstractive. On abstractive technique, summaries are generated starting from selecting outstanding sentences on source text. Abstractive summaries are created by regenerating the content extracted from source text, through that phrases are reformulated by terms fusion, compression or suppression processes. In this manner, paraphrasing sentences are obtained or even sentences were not in the original text. This summarize type has a major probability to reach coherence and smoothness like one generated by human beings. The present work implements a method that allows to integrate syntactic, semantic (AMR annotator) and discursive (RST) information into a conceptual graph. This will be summarized through the use of a new measure of concept similarity on WordNet.To find the most relevant concepts we use PageRank, considering all discursive information given by the O”Donell method application. With the most important concepts and semantic roles information got from the PropBank, a natural language generation method was implemented with tool SimpleNLG. In this work we can appreciated the results of applying this method to the corpus of Document Understanding Conference 2002 and tested by Rouge metric, widely used in the automatic summarization task. Our method reaches a measure F1 of 24 % in Rouge-1 metric for the mono-document abstract generation task. This shows that using these techniques are workable and even more profitable and recommended configurations and useful tools for this task.es_ES
