Quepasa is among the first "pure-play" Hispanic-oriented technology companies in the United States to design, own, and operate proprietary internet search technologies and related large-scale online distribution platforms focused exclusively on the online Hispanic market. The Quepasa internet crawler is designed with directed graph traversal capability to locate pages primarily relevant to the Hispanic community and is built around a powerful clustering platform that allows it to scale horizontally for any number of documents in any span of time, depending on hardware resources. The crawler obeys all published standards for crawler etiquette and uses probabilistic methods to determine next-queue-selection. Quepasa indexing and ranking agents use a large set of methods to mark relevancy for every word in every document, using data derived from body text, title text, keywords, citation text, citation authority, word frequency, word location, "spam" detection variables, and a complex set of other variables that have been determined through research to contribute to overall relevancy. Quepasa query agents collate and recalculate the document elements according to relevancy determination algorithms, which calculate and utilize such important factors as word proximity, categorical typing, relative rank valuation, per-document word frequency, and host origin. Like the crawler, the query agent is also linearly scalable to accommodate traffic. More traffic requires more hardware -- no additional complexity. Quepasa result aggregation servers track usage patterns, logging impression and click statistics, while providing an XML-based client API with which Quepasa search partners can easily integrate. The end result of the integration of these agents is a highly effective, relevant platform for document indexing and retrieval. The platform adds intelligent file locking, addressing, buffering, and caching semantics to it. It uses custom-designed hash-based addressing schemes that reduce reliance on disk seek latency and take advantage of the availability of cheap, abundant, onboard memory where possible; using intelligent lexical analysis methods and fast set intersection and union algorithms for effective ranking, making heavy use of industry-standard MPI to enable near-linear scalability across the system. Quepasa utilizes the latest innovations in J2EE technology for a stable, secure, enterprise-class method of client interaction. About Quepasa Corporation: In business since 1998, Quepasa's proprietary search results are now featured on leading Hispanic online destinations throughout the U.S. and Latin America. In November of 2003, Quepasa announced the deployment of the first generation of its wholly owned, proprietary search technology.
