    TEI, Ontologies, Linked Open Data: Geolat and Beyond by Fabio Ciotti, Maurizio Lana, Francesca Tomasi

    Published 2015-12-01
    “…These annotations are linked to a set of ontologies that give them formal semantics, and can finally be exposed the as linked open data, in order to improve the documents’ interoperability with other existing LOD and to enhance information retrieval possibilities. The paper is organized as follows: first we introduce the project in order to explain the steps needed to complete it (section 2); then we describe the ontological modeling and the TEI encoding in Geolat, by focusing on both places and persons (section 3). …”

    An Adaptive Subspace Similarity Search Approach by Jianxin Ren, Huahui Chen

    Published 2015-07-01
    “…In recent years,such database fields as multimedia information retrieval,similarity join and time series matching,where similarity search has attracted much attention.Existing researches mostly compute nearest neighbor to solve problems about search target set,such as kNN and kNNJ,by metric distance functions in the Euclidean space.But some studies showed that high dissimilarity dimensions had got great effect on the accuracy of answer and flexibility and robustness still were lacked in corresponding solutions.Thus centralized dynamic subspace or partial dimensions similarity search problem and algorithms were proposed at first.Furthermore,with the emerge of very large dataset,centralized algorithms can,t extend very well.Finally,the distributed ones under hadoop framework were proposed.Experiments prove that distributed algorithms outperform centralized ones in the performance without accuracy loss.…”

    A Grammar-Based Semantic Similarity Algorithm for Natural Language Sentences by Ming Che Lee, Jia Wei Chang, Tung Cheng Hsieh

    Published 2014-01-01
    “…Natural language, in opposition to “artificial language”, such as computer programming languages, is the language used by the general public for daily communication. Traditional information retrieval approaches, such as vector models, LSA, HAL, or even the ontology-based approaches that extend to include concept similarity comparison instead of cooccurrence terms/words, may not always determine the perfect matching while there is no obvious relation or concept overlap between two natural language sentences. …”

    Blog screening and mining based on temporal features and hybrid search in big data by Lina ZHANG, Tai KUANG, Diqing JIANG

    Published 2017-01-01
    “…Concerning that the correlation degree of the existing methods of blog screen and mining is loose and the information retrieval of the methods is deficient,a method based on temporal feature and hybrid search method was proposed.Considering the user reviews are important sources of evidence combination,the average number of reviews for blogs,the sources of BM25 relevance scores,the longest blog BM25 scores and time range between the latest related blog paper and the oldest related blog paper are being as the temporal feature sets.In addition,considering local search advantage of linear search(LS) and global search advantage of differential evolution(DE),the two kinds of information search methods were combined.BlogS06 data set was used in the experiment which was consists of blog home pages,XML source files and its blog portal pages,it was used for TREC 2007 and TREC 2008 blog mining experiments.Experimental results show that the proposed method can obtain satisfactory results in terms of running time and effectiveness.…”

    Research on LBS privacy preservation based on pseudorandom permutation in road network by Chang-li ZHOU, Hui TIAN, Chun-guang MA, Song-tao YANG

    Published 2017-06-01
    “…A method of privacy preservation based on pseudorandom permutation was put forward for the issues of location privacy and query content privacy.Firstly,the distribution information of points of interest (PoI) based on the vertexes in the road network was organized,each single road vertex was taken as the foundational processing object.Based on the pseudorandom permutation,a permutation scheme of the point-of-interest records at the LBS server's end was put forward,a 32-bit random seed was adopted to generate a permuted table in the scheme,and the point-of-interest records were encrypted and permuted according to the table.These processed records were stored in the LBS database.Then a trusted intermediate server,replacing of the user,issued a query request with a record number instead of the query content to the LBS server.The LBS server could not determine which kind of PoI the user was interested in or which road section the user was locating on,and therefore the scheme achieved private information retrieval.Finally,the efficiency in the metrics of query accuracy,communication overhead and processing time was also analyzed.By the performance analysis and extensive experiments,the proposed scheme is proved to be location untraceable and query content uncorrelation.…”
