A Query-by-Similarity Indexing Strategy for Web Forms
نویسندگان
چکیده
Search engines do not provide speci c searches for Web forms related to the Deep Web, in particular, similarity search. To deal with this lack, we propose a query-by-similarity system called WF-Sim, and this paper presents the indexing strategy adopted by WF-Sim for querying-by-similarity Web forms. It is centered on suitable index structures to the main kinds of queries posed on Web forms, as well as some optimizations in order to reduce the number of index entries. To evaluate the indexes performance, we ran experiments on twoWF-Sim persistence strategies: le system and database. We also compare the performance of our indexes against the traditional keyword-based index, and the results were promising.

The Sweet Spot between Inverted Indices and Metric-Space Indexing for Top-K-List Similarity Search
We consider the problem of processing similarity queries over a set of top-k rankings where the query ranking and the similarity threshold are provided at query time. Spearman’s Footrule distance is used to compute the similarity between rankings, considering how well rankings agree on the positions (ranks) of ranked items (i.e., the L1 distance). This setup allows the application of metric ind...

متن کاملQuery-Driven Indexing in Large-Scale Distributed Systems
Efficient and effective search in large-scale data repositories requires complex indexing solutions deployed on a large number of servers. Web search engines such as Google and Yahoo! already rely upon complex systems to be able to return relevant query results and keep processing times within the comfortable sub-second limit. Nevertheless, the exponential growth of the amount of content on the...
