“…Silverstein and Henzinger [13] presented a correlation analysis of query logs and studied the interaction of terms within queries; the results suggested that it might be useful for search engines to consider query terms as parts of phrases. Chaudhuri et al [6] observed that the distribution of combinations of multiple terms in query logs exhibited power law behavior, while Chau et al [5] confirmed that the distribution of n-gram term combinations also followed the Zipfian distribution (a special kind of power law distribution). However, to the best of our knowledge, correlation between pairs of terms has not been utilized in the context of list caching in search engines.…”

Caching technologies have been widely employed to boost the performance of Web search engines. Motivated by the correlation between terms in query logs from a commercial search engine, we explore the idea of a caching scheme based on pairs of terms, rather than individual terms (which is the typical approach used by search engines today). We propose an inverted list caching policy, based on the Least Recently Used method, in which the co-occurring correlation between terms in the query stream is accounted for when deciding on which terms to keep in the cache. We consider not only the term co-occurrence within the same query but also the cooccurrence between separate queries. Experimental results show that the proposed approach can improve not only the cache hit ratio but also the overall throughput of the system when compared to existing list caching algorithms.

“…Studying the characteristics of Chinese‐English mixed language queries in web searching will be fruitful for a better understanding of users’ needs behind the queries, and inform the construction of controlled vocabularies and query expansion. Although previous studies (Chau, Fang, & Yang, ; Chau et al, ; Lu, Fang, & Yang, 2006) have analyzed the characteristics of search queries in English and Chinese, their findings may not be applicable to Chinese‐English mixed language queries, due to the great discrepancy between these two languages. To our best knowledge, no previous research has explicitly studied Chinese‐English mixed language queries in depth.…”

With the increasing number of multilingual web pages on the Internet, multilingual information retrieval has become an important research issue. While queries are the key element of information retrieval process, mixed‐language queries have not yet been adequately studied. This study investigates the search topics and user intents of Chinese‐English mixed language queries submitted to a Chinese web search engine, and develops a typology of English terms used in those mixed language queries. The preliminary findings show that the category of search topics and distribution of user intents differ from those of monolingual queries reported in previous studies, suggesting a specific searching behavior of Chinese‐English mixed language queries users. The findings of this study could provide useful insights in understanding specific searching behavior of Chinese‐English mixed language queries users, and inform the construction of controlled vocabularies and cross‐lingual query expansion.
