Comparing Move Choices of Chess Search Engines
Anecdotal evidence exists that in many positions two distinct chess engines will choose different moves and, moreover, that their top-n ranking of move choices also differ. Here we set out to quantify this difference, including the difference between move choices by chess engines and those made by humans. For our analysis we used FRITZ 8 and JUNIOR 9 as representative chess search engines and t...
متن کاملComparing Performance of Different Search Engines through Experiments
This chapter reports the results of a project attempting to assess the performance of a few major search engines from various perspectives. The search engines involved in the study include the Microsoft Search Engine (MSE) when it was in its beta test stage, AllTheWeb, and Yahoo.

متن کاملEvaluating Web Search Engines Using Clickthrough Data
The web is a highly dynamic environment: documents disappear or become outdated, new documents appear, the query distribution changes. In order to keep up, search algorithms must be continuously tuned and re-tuned. Each iteratively tuned algorithm needs to be evaluated against the current web corpus. But since the web is so frequently changing, relevance judgments acquired at one point in time ...
متن کاملThink local, search global? Comparing search engines for searching geographically specific information
This study evaluates the retrieval of New Zealand information using three local New Zealand search engines, four major global search engines and three metasearch engines. Searches for NZ topics were carried out on all the search engines, and the relative recall calculated. The local search engines did not achieve higher recall than the global search engines or metasearch engines, but no search ...
متن کاملSpatial data discovery using general purpose web search engines
To find spatial data, interested parties have to know where and how to access existing geospatial web services or geoportals. People in geographic information communities are aware of such online platforms, but what about others? Finding relevant spatial data that satisfy the needs of the requesters is still an issue. In this paper, we propose a method for documenting spatial data for both huma...
