  1. Motivated by this observation, this paper studies the problem of efficiently processing k nn k - ge 1 search on r - tree - like structures storing historical information about moving object trajectories. two algorithms are developed based on best - first traversal paradigm, called bfp k nn and bft k nn, which handle the k nn retrieval with respect to the static query point and the moving query trajectory, respectively. both algorithms minimize the number of node access, that is, they perform a single access only to those qualifying nodes that may contain the final result

  3. Experiments are performed and results show : 1 the popular retrieval models the okapi s bm25 model and the smart s vector space model with length normalization do not perform well for document similarity search ; 2 the proposed model based on texttiling is effective and outperforms other models, including the cosine measure ; 3 the methods for the three components in the proposed model are validated to be appropriately employed

  4. Document similarity search is to find documents similar to a given query document and return a ranked list of similar documents to users, which is widely used in many text and web systems, such as digital library, search engine, etc. traditional retrieval models, including the okapi s bm25 model and the smart s vector space model with length normalization, could handle this problem to some extent by taking the query document as a long query
