    Based on the framework of Linked Data application, this paper prensents a semantic user modeling framework, and designs a semantic user model in the context of semantic Web, then analyzes the framework in detail. This framework mainly consists of two parts: firstly, it discusses the methods and strategies for discovering and acquiring users data from the LOD cloud; secondly, it introduces the processes for constructing a user model using these data, which includes such steps as concept mapping, identity resolution, data fusion and model generation.

    There exists “Descriptor-RelationName-RelatedTermsSet” structural feature between descriptor and its associated terms in OntoThesaurus, and the relationship between the extended subproperties and their superproperty should be visualized, so this paper presents clusters layout algorithms to meet the visualization need of OntoThesaurus. An intuitive and vivid effect is produced, which is done by combing the force-directed algorithm of the information visualization community with animation technology. The initial prototype can process NKOS data represented in Semantic Web description languages such as OntoThesaurus, SKOS, CNKOS, which are based on RDF triples, and therefore can be generally used to visualize the instances of concept class in NKOS (especially Chinese NKOS).

    This paper represents the descriptor, non-descriptor and semantic relationships of Chinese Agricultural Thesaurus (CAT) as SKOS, and develops an application to convert CAT to CAT/SKOS automatically, and indexes millions of agricultural abstracts semantically based on CAT/SKOS, Solr and the improved Lucene-SKOS plugin. Then it realizes a semantic retrieval prototype system, which supports cross-language search (Chinese and English), and can also extend and reconstruct the query based on semantic relationship in CAT/SKOS. Finally, the authors make some prospects on the future applications of CAT/SKOS such as the publication as Linked Data.

    Social text streams have rich contextual information and huge participants who communicate with informal steams. It needs to find suitable solutions to detect burst topics from this kind of data. In this paper, the authors comb through the concepts, the characteristics of social text stream data and the presentation forms of burst topics. It also summarizes the main research ideas and the basic procedures of burst topic detection towards social text stream data in three dimensions: textual content, social, and temporal. The principal approaches to make use of social features, such as user participation, social context and community structure evolution, for burst topic detection are generally discussed.

    This paper adopts a new framework named Minimal Recursion Semantics (MRS) to represent sentence meaning. Taking Chinese Quantitative Noun Phrases(QNP) as main analysis object according to MRS’s characteristics,the paper designs a suitable MRS representation for Chinese QNP and shows a reasonable HPSG analysis of QNP.It also implements a grammar analysis experiment, and the result shows the grammer is basically applicable to Chinese QNP representation.

    In order to improve SPARQL query efficiency, this paper uses RDF schema to simplify the BGP of SPARQL, and then estimates each node’cardinality and the weight of each edge through B-tree indexes quickly. After that, it uses the methods of joining cost estimation and dynamic programming for the optimal logical query plan. The result of the experiment shows that the new method improves the SPARQL query efficiency,while the performance of this method is as good as Sesame, and much better than Jena.

    Based on the former researches, this paper studies the motivations of consumers to spread e-WOM on the online feedback system by benefit factors and cost factors. Meanwhile, it brings the motivation crowding effect into the analysis model, and discusses the effect of extrinsic motivation on intrinsic motivation and internalizes extrinsic motivation. Finally, several proposals for encouraging customers to spread on the online feedback system are provided.

    This paper aims at resolving the semantic mining problem of product online reviews by using the technology of sentiment orientation analysis. The sentiment orientation polar is firstly analyzed and the intensity of sentiment orientation analysis is computed to correctly express the inner semantic of product online reviews. The reviews of Xiaomi mobile phone and Motorola ME525+ mobile phone on Taobao are chosen to do the experiments. The results show that the precision of each auto-scoring of sentiment orientation analysis can reach 80% and most attribute indicators of products can get correct sentiment orientation polar, Which can help Web users to make correct purchase decisions to some extent.

    This paper constructs a conceptual model of initial trust and analyses the effect of the seven antecedent variables (market perception, public validity, structure quality, information quality, window friendly, security system, trust orientation) on the initial trust of the dating sites based on the literature screening. Using SPSS19.0 and Lisrel8.8 to do an empirical test and analysis of the model on the basis of the questionnaire, and the results show that market perception, public validity, information quality, window friendly, security system and trust orientation can affect the initial trust of potential users significantly. Finally, suggestions and research prospects are put forward.

    In order to obtain the behavior of local users which include operation on digital libraries and personalized push service, and application software on the system, a driver stage-based application access control strategy is proposed, which can implement real-time monitoring and recording of the I/O operation. This paper implementes the drive-level local user behavior monitoring system based on VC++, using technologies of file driver stage, Web crawler and database. Operation log obtained through the system also can be used as the electronic survey data designed for personalized push service of the library.

    This paper applies mathematical statistics corpus linguistics to generate mapping rules between DDC(Dewey Decimal Classification) and CLC(Chinese Library Classification). A test system is then built up and the DDC-CLC mapping table is produced through the system. The mapping table is examined by bibliographic records with DDC and CLC data so that continuously improved mapping rules and tables can be obtained.
