A lack of information forces many tourists on the same crowded paths. The Dynamic Tour Guide (DTG) is a mobile agent hich computes an itinerary of a couple of hours to explore a city. For this the DTG interrogates Tour Building Blocks (TBB), e.g. potential sights or restaurants, to determine current information, e.g. opening hours or availability. An ontology is used to capture the profiles of ...

The following article examines different educational systems for tour guides in Slovenia as well as abroad. Based on the survey carried out among tour guides and tours managers in Slovenia their opinion on the usefulness of knowledge gained in the process, their viewpoint on the current form of education and the level of difficulty of obtaining a license for a tour guide or tour manager was inv...

The World Wide Web provides information for most tourist locations and thus has enormous influence on tourists’ decisions. However, Web applications rarely support all phases of tour planning. The city of Görlitz offers website visitors an opportunity to plan individual city tours in advance by specifying personal interests and tour preferences. Using this information, the system creates a pers...

We consider constrained versions of the prize-collecting traveling salesman and the minimum spanning tree problems. The goal is to maximize the number of vertices in the returned tour/tree subject to a bound on the tour/tree cost. We present a 2-approximation algorithm for these problems based on a primal-dual approach. The algorithm relies on finding a threshold value for the dual variable cor...

Professional golf is an area that is particularly attractive to study because it models a perfectly competitive economy where payoffs are directly related to individual productivity (Scully 2002). Since one‟s earnings on the PGA Tour are based on individual performance, different skill factors and other variables such as tour experience and the number of events entered can be compared to determ...

We use a modified version of the halo-based group finder developed by Yang et al. to select galaxy groups from the Sloan Digital Sky Survey (SDSS DR4). In the first step, a combination of two methods is used to identify the centers of potential groups and to estimate their characteristic luminosity. Using an iterative approach, the adaptive group finder then uses the average mass-to-light ratio...

36 37 As tour-based methods for activity and travel participation patterns replaces trip-based methods, time-38 of-day (TOD) choice modeling remains problematic. In practice, most travel demand model systems 39 handle tour scheduling via joint-choice multinomial logit (MNL) models, which suffer from the well-40 known independence of irrelevant alternatives (IIA) assumption. This paper introduce...

In order to promote the development of further research on “object finder”, this paper aims utilize existing mode and modern scientific technological progress. By combining with TRIZ innovation method, shortcomings original plans are analyzed, intending propose a new concept for object finder, which consists two components, i.e., “locator” “searcher”. Additionally, explores both “searcher” resp...

This paper presents a prototype of case-based reasoning, built for the agricultural domain. Its aim is to forecast the allocation of a new energy crop, the miscanthus. Interviews were conducted with french farmers in order to know how they make their decisions. Based on interview analysis, a case base and a rule base have been formalized, together with similarity and adaptation knowledge. Furth...
