    • A pipelined architecture for distributed text query evaluation 
      Moffat, Alistair; Webber, William; Zobel, Justin; Baeza Yates, Ricardo (2007)
      Two principal query-evaluation methodologies have been described for cluster-based implementation of distributed information retrieval systems: document partitioning and term partitioning. In a document-partitioned system, ...
    • Cinco meses de pandemia 
      Baeza Yates, Ricardo (Universidad Tecnológica Metropolitana Estado Chile, 2020)
      Desde finales de febrero de 2020 Chile ha vivido un acontecimiento único en los últimos 99 años. Una pandemia que ha causado más fallecidos que el terremoto de 1939 en Chillán, donde oficialmente murieron casi 6 mil ...
    • Cómo funciona la web 
      Arenas, Marcelo; Baeza Yates, Ricardo; Gutiérrez Gallardo, Claudio; Hurtado Larraín, Carlos; Marín, Mauricio; Navarro, Gonzalo; Piquer Gardner, José; Rodríguez Tastets, M. Andrea; Ruiz del Solar, Javier; Velasco, Javier (Centro de Investigación de la Web, Departamento de Ciencias de la Computación, Universidad de Chile, 2008)
    • Crawling a Country: Better Strategies than BreadthFirst for Web Page Ordering 
      Baeza Yates, Ricardo; Castillo Ocaranza, Carlos; Marín, Mauricio; Rodríguez, Andrea (2005)
      This article compares several page ordering strategies for Web crawling under several metrics. The objective of these strategies is to download the most \important" pages \early" during the crawl. As the coverage of ...
    • Dynamics of the Chilean web structure 
      Baeza Yates, Ricardo; Poblete Labra, Bárbara (ELSEVIER, 2006-07-14)
      In this paper we present a large scale study on the evolution of the Web structure of the Chilean domain (.cl) from 2000 to 2004, focusing on the Web site transitions in the structure. This is the study of the largest time ...
    • On the image content of a web segment: Chile as a case study 
      Jaimes, A.; Ruiz del Solar, Javier; Verschae, Rodrigo; Baeza Yates, Ricardo; Castillo, C.; Yaksic, D.; Davis, E. (Rinton Press, 2004)
      We propose a methodology to characterize the image contents of a web segment, and we present an analysis of the contents of a segment of the Chilean web (.CL domain). Our framework uses an efficient web-crawling architecture, ...
    • Proteomic analysis of peach fruit mesocarp softening and chilling injury using difference gel electrophoresis ... 
      Nilo Poyanco, Ricardo; Saffie, Carlos; Lilley, Kathryn; Baeza Yates, Ricardo; Cambiazo Ayala, Liliana; Campos Vargas, Reinaldo; González Canales, Mauricio; Meisel, Lee; Retamales Aranda, Julio; Silva Ascencio, Herman; Orellana López, Ariel (2010)
      Background: Peach fruit undergoes a rapid softening process that involves a number of metabolic changes. Storing fruit at low temperatures has been widely used to extend its postharvest life. However, this leads to undesired ...
    • A Rapid and Efficient Method for Purifying High Quality Total RNA from Peaches (Prunus persica) for Functional ... 
      Meisel, Lee; Fonseca García, Beatriz; González, Susana; Baeza Yates, Ricardo; Cambiazo Ayala, Liliana; Campos, Reinaldo; González Canales, Mauricio; Orellana López, Ariel; Retamales Aranda, Julio; Silva Ascencio, Herman (2005)
      Prunus persica has been proposed as a genomic model for deciduous trees and the Rosaceae family. Optimized protocols for RNA isolation are necessary to further advance studies in this model species such that functional ...
    • Seasonal variation in the development of chilling injury in 'O'Henry' peaches 
      Campos Vargas, Reinaldo; Becerra, Oscar; Baeza Yates, Ricardo; Cambiazo Ayala, Liliana; González Canales, Mauricio; Meisel, Lee; Orellana López, Ariel; Retamales Aranda, Julio; Silva Ascencio, Herman; Defilippi Bruzzine, Bruno (ELSEVIER, 2006-09-11)
      Mealiness, a chilling injury symptom, is one of the most important quality limiting factors in peaches and nectarines exported from Chile. The development of mealiness was analyzed over 3 years to quantify the expression ...
    • Towards formal evaluation of collaborative work 
      Baeza Yates, Ricardo; Pino Urtubia, José (UNIV SHEFFIELD DEPT INFORMATION STUDIES, 2006-07)
      Introduction. Computer Supported Cooperative Work (CSCW) projects are difficult to evaluate when implemented at most organizations. There are many variables and some of these are qualitative and hard to assess. However, ...
    • Two-Dimensional Distributed Inverted Files 
      Feuerstein, Esteban; Marín, Mauricio; Mizrahi, Michel; Gil Costa, Verónica; Baeza Yates, Ricardo (2009)
      Term-partitioned indexes are generally inefficient for the evaluation of conjunctive queries, as they require the communication of long posting lists. On the other side, document-partitioned indexes incur in excessive ...
    • XQL and Proximal Nodes 
      Baeza Yates, Ricardo; Navarro, Gonzalo (2002)
      Despite that several models to structure text documents and to query on this structure have been proposed in the past a standard has emerged only relatively recently with the introduction of XML and its proposed query ...
