ABSTRACT
Although Web search engines have become information gateways to the Internet, for queries containing technical terms, search results often contain pages that are difficult to be understood by non-expert users. Therefore, re-ranking search results in a descending order of their comprehensibility should be effective for non-expert users. In our approach, the comprehensibility of Web pages is estimated considering both the document readability and the difficulty of technical terms in the domain of search queries. To extract technical terms, we exploit the domain knowledge extracted from Wikipedia. Our proposed method can be applied to general Web search engines as Wikipedia includes nearly every field of human knowledge. We demonstrate the usefulness of our approach by user experiments.

Recommendations
Adaptive ranking of search results by considering user's comprehension
ICUIMC '10: Proceedings of the 4th International Conference on Uniquitous Information Management and CommunicationGiven a search query, conventional Web search engines provide users with the same ranking although users' comprehension levels can be different. It is often difficult especially for non-expert users to find comprehensible Web pages from the list of ...
Improving Ranking Consistency for Web Search by Leveraging a Knowledge Base and Search Logs
CIKM '15: Proceedings of the 24th ACM International on Conference on Information and Knowledge ManagementIn this paper, we propose a new idea called ranking consistency in web search. Relevance ranking is one of the biggest problems in creating an effective web search system. Given some queries with similar search intents, conventional approaches typically ...
Identifying popular search goals behind search queries to improve web search ranking
AIRS'11: Proceedings of the 7th Asia conference on Information Retrieval TechnologyWeb users usually have a certain search goal before they submit a search query. However, many laypersons can't transform their search goals into suitable queries. Thus, understanding original search goals behind a query is very important for search ...
