The Story of Mirador: A Search Engine for Latin America
"What is the use of having access to so much information, if when
I need something, I cannot find anything Im looking for?"
The amount of information on the Internet has been growing exponentially
each day for several years now. This phenomenon made clear the
need to have a tool that would ease finding the information searched
for, considering the particular criteria of the person performing
the search. This is why the search engines and the automatic and
semiautomatic systems that gather and index data have come to
life, helping, with some limitations, locate the sites at which
users may find what theyre looking for.
In our Latin American countries, we may gladly confirm that the
trend is the same, and the information that we, Latin Americans,
are publishing on the Internet is growing daily not only in quantity
but also in quality.
Origins of Mirador
Some time ago, in the course of the III Central American Forum
of Electronic Communications, guided by this perception, an agreement
was achieved over the need and convenience of having a regional
search engine that allowed the focus to fall on finding sites
and pages that presented local contents and, therefore, were more
appropriate to the information needs of the region.
Some months after that, in El Salvador, within the SVNet group, SV Top Level Domain manager (SV represents El Salvador, according to international standards
established by the ISOInternational Organization for Standardization),
a proposal was made to have a search engine for the country regardless
of the fact that national Web sites, under domain SV, may already
be registered in large databases such as Yahoo!, Altavista, and
Excite, so that they could have their contents revised and indexed
automatically in order to ease the search and finding of information.
The project was undertaken as a graduation work by the Universidad Centroamericana "José Simeón Cañas" (UCA), a member of SVNet, and thanks to the enthusiasm and research
work done, the concept and later the technical aspects were solved
and the search engine was significantly named Mirador.
The name was proposed within the III Foro Centroamericano de Comunicaciones
Electrónicas, because besides its obvious meaning (mirador, in Spanish, is a sightseeing place, usually on the top of a
hill), the only way to have some distraction during that event
was to walk to a nearby mirador. The nearest city was located
quite far away.
As part and sample of Latin American collaboration, the Mirador
logo was created and developed by Sylvia Cadena of Colombia as
a very special favor to this project.
Afterward, thanks to the collaboration and enthusiastic wish to
improve the user interface design, Vida Luz Arista of Nicaragua
and her team introduced improvements and additional elements that
have made Mirador more attractive and easy to use.
The Technology Used
From the technology point of view, this is an application of appropriate
technology, since a symbiosis of cost-free products on the Internet
has been accomplished. Basically, we are using the robot program
called Combine, developed in Sweden, and the indexer and search engine called
WWWIsis, developed by Bireme.
Combine is technically defined as a robot program to collect web resources
on the Internet. This definition matches that of a spider-type
programthat is, a program that, when activated, travels the Internet
(or an specified subset of it), obtaining data such as the address,
the title, and more, from the Web pages it encounters, recursively,
but avoiding repetition of the inspection of a certain page in
the same run. Combine consists of three modules, called Cabin,
Harvester, and Harvester Data Base (HDB). Cabin is the module
that controls the other two; Harvester does the search, from a
starting URL (uniform resource locator), and sends its findings
to the HDB; the Harvester Data Base, in turn, stores the collected
data in a structure of its own, waiting for a potential future
process that generates the indexes.
WWWIsis, on its side, has been designed to interface the MicroISIS
(textual DBMS developed by UNESCO) databases with the World Wide
Web. In this project and as part of the original contributions,
some programs were developed that prepare the output of the HDB
from Combine in international format ISO-2709, so WWWIsis may
create indexes with this information and make the search possible
through words in the title, part of the text, and meta keywords
on a Web page.
Other Mirador Sites
The Mirador site of El Salvador (SV) was launched officially at
http://www.svnet.org.sv/mirado r/ on May 14, 1998. From this experience, and having announced it
at several Central and Latin American forums, some organizations
in other countries showed their interest in installing and implementing
a local version in each nation.
So, on October 22, 1998, and under the sponsorship of the Red de Desarrollo Sostenible de Guatemala (Sustainable Development Network) and with the support of UCA of El Salvador, the Mirador site for Guatemala (GT) was launched,
at http://www.rds.org.gt/mirador/.
Later, private enterprise Ideay of Nicaragua (NI) initiated joint efforts with UCA to install the Mirador site for Nicaragua. This site was launched
at the end of July 1999 and may be found at http://buscador.ideay.net.ni/ ..
Likely, the Red de Desarrollo Sostenible de Honduras, also working jointly with UCA of El Salvador, installed and launched the Mirador site for Honduras
(HN), on August 13, 1999. The address of this site is http://www.rds.org.hn/mirador/.
On September 29, 1999, in the equipment of the Red de Desarrollo Sostenible de Costa Rica, with the support of UCA, the Mirador site for Costa Rica was successfully started at
http://www.rds.ucr.ac.cr/mira dor/.
By a fortuitous coincidence, just days before officially receiving
the Panama Canal, on December 22, 1999, PanNet, in Panama, and thanks to support by UCA, inaugurated the Mirador site for Panama, at http://www.mirador.pannet.pa/ ..
Currently, it is hoped that soon other Mirador sites will be in
cooperative work progress, and therefore other countries are invited
to join this effort and initiative in favor of the growth and
development of Internet in our regions.
