Finding useful information from the web which has a large and distributed structure requires efficient search strategies. Focused crawlers selectively retrieve Web documents that are relevant to a predefined set of topics. To intelligently make decisions about relevant URLs and web pages, different authors had proposed different strategies. In this paper we review and compare focused crawling strategies, studied and published during the past few years. We also give the details of various issues related to focused crawling. Keywords— Semantic web, crawler, focused, ontology.

The main purpose of this chapter is to show if the Barranca del Rio Santiago is a tourist attraction and ecotourism so it could be included in the Guadalajara brand, which is focused on national tourism. The research is exploratory and descriptive in nature. Only the national indicators of the Metropolitan Area of Guadalajara were taken in reference to motivation, what they like most, means by which they arrive at the destination, etc. SECTUR establishes in the latest competitiveness agenda of tourist destinations in Mexico that Guadalajara has a large number of natural destinations, including the Barranca del Río Santiago. This destination has a high ecological, recreational, and landscaping value, largely unknown by the local population, and consequently it can become a new product for the ecotourism sector.
