Image retrieval by hypertext links

This paper presents a model for retrieval of images from a large World Wide Web based collection. Rather than considering complex visual recognition algorithms, the model presented is based on combining evidence of the text content and hypertext structure of the Web. The paper shows that certain types of query are amply served by this form of representation. It also presents a novel means of gathering relevance judgements

User experiments with the Eurovision cross-language image retrieval system

In this paper we present Eurovision, a text-based system for cross-language (CL) image retrieval. The system is evaluated by multilingual users for two search tasks with the system configured in English and five other languages. To our knowledge this is the first published set of user experiments for CL image retrieval. We show that: (1) it is possible to create a usable multilingual search engine using little knowledge of any language other than English, (2) categorizing images assists the user's search, and (3) there are differences in the way users search between the proposed search tasks. Based on the two search tasks and user feedback, we describe important aspects of any CL image retrieval system

UTSE: Construction of Optimum Timetables for University Courses - A CLP Based Approach

The construction of timetables for universities or schools is an extremely complex problem, whose manual solution requires much effort. The set of all possible solutions, that is the search space of the problem, is very large, at least in the realworld examples. An acceptable solution is one that satisfies all the problem constraints. The problem becomes even more difficult if someone wants to generate an optimum timetable according to some heuristic criteria. Various attempts have been made so far on the automatic solving of the timetabling problem by a computer. In this paper, a method is proposed for the construction of optimum timetables for university courses. A specific system is presented which has been used for the timetabling procedure of the Department of Informatics of the University of Athens. The software platform of the implementation is an instance of the Constraint Logic Programming class of languages, the ECL i PS e system. ECL i PS e is proved to be an appropriate vehicle for managing the complexity of the timetabling problem
