A comparison of search engine using “tag title and abstract” with CiteULike — An initial evaluation

Abstract

At present, the performance and capabilities of web search engine are vital. Most researchers use search engines for research papers related to their topics of interest. This paper demonstrates the initial comparison search results between a search engine using the indexing method of “tag title and abstract” and the native CiteUlike engine. The retrieval performance of these two search engines are evaluated using mean values of Normalized Discount Cumulative Gain (NDCG). The results illustrate that the search engine with indexer using “tag, title, and abstract” provides better search results as compared to CiteUlike, particularly for those documents in the first two rank which would be considered as the most relevant documents. This primary evaluation in the experiments implies that the chosen heuristic indexer may improve the efficiency of web resource searching on social bookmarking websites.
