Preliminary Workshop on Evaluation of Geographic Information Retrieval Systems for Web Documents
نویسندگان
چکیده
Geographic Information Task (GeoTask) is one of the newly proposed tasks at the NTCIR-4 WEB. Geographic information is close to our daily lives, and is one of the real ways to access Web information. Researches and developments of such aspects have been increasing recently, however, comparative evaluations of such kinds of techniques has not been carried out so far. GeoTask focused on the technology that the system extracts geographic information from Web documents relevant to a given viewpoint. The aim of this workshop is to expedite and advance researches and developments of Geographic IR technologies for the Web, therefore we are going to build reusable test collection for evaluating various methods of Geographic IR for Web documents. In this paper, challenges for searching geographic information are described, which are discussed through the explanation of our research on developing geographic IR systems.

Measuring Effectiveness of Geographic IR Systems in Digital Libraries - Evaluation Framework and Case Study
Common search engines process users’ queries (i.e., information needs) by retrieving documents from pre-built term-based indexes. For digital libraries, such approaches are limited regarding particular contexts, such as specialized collections (e.g., cultural heritage collections) or specific retrieval criteria (e.g., multidimensional criteria). In this paper, we consider Information Retrieval ...

This article looks at the access to geographic information through a review of information science theory and its application to the WWW. The two most common retrieval systems are information and data retrieval. A retrieval system has seven elements: retrieval models, indexing, match and retrieval, relevance, order, query languages and query specification. The goal of information retrieval is t...
متن کاملGeographically Aware Web Text Mining
Text mining and search have become important research areas over the past few years, mostly due to the large popularity of the Web. A natural extension for these technologies is the development of methods for exploring the geographic context of Web information. Human information needs often present specific geographic constraints. Many Web documents also refer to specific locations. However, re...
