  With the normative analysis method, this paper classifies Internet metaphor expressions into two types: operating metaphor and displaying metaphor. Based on some typical methods in visual design, literature rhetoric and other realms, it concludes five specific methods for metaphor design. With regard to the process of Internet metaphor design, it is proposed that there are two design stages: Ontology analysis and metaphor design. The second stage can be divided into three steps: metaphor accumulation(generating),selection(evaluation),and recreating (developing).Finally, an example is applied to describe how to conduct the methods and steps mentioned above to accomplish a metaphor design.

  The retrieval efficiency and the retrieval capability are considered as two major problems existing in CBIR systems. In order to improve the retrieval efficiency,the authors present a new CBIR application based on large databases in distributed environment using DHCIR (Distributed Image Retrieval method based on Color Model to Histogram Conversion) algorithm by reviewing past researches in CBIR and distributed computing. A new image retrieval system using this method is also developed. The test results show this application can provide stable, fast and efficient image retrieval functions to improve the retrieval speed and accuracy.

  At present, title and description of goods are rarely considered in the research of online reviews at home and abroad, this makes the mining process blindly and mining results are not high accurate. In this article, the authors use the cluster analysis method, consider the title and description, set up a three-level mining model to analyze the online comments, at the same time, a location-clustering-algorithm is proposed. Experimental results show that the method improves the accuracy of mining and reduces the mining time.

  Organizational Citizenship Behavior (OCB) is critical to the success of a virtual community. The model of factors influencing virtual community OCB is developed based on the literature. The model is tested with data collected from virtual community users using survey. It is found that the factors of sense of virtual community, cognitive trust, affective trust, attachment motivation, social support orientation and disposition trust, have significant impact on the virtual community OCB. The psychological factors of attachment motivation, social support orientation and disposition trust have impact on sense of virtual community through the factors of trust.

  According to the sample collected by search engines, the Spatial Error Model (SEM), considering spatial dependence of academic information on Internet is established, which is a quantitative method to analyze the spatial agglomeration phenomenon of academic information on Internet. It is found that spatial dependence exists and SEM is the best model when analyzing this problem. Five factors are main influence factors of spatial distribution of academic information on Internet,and they are economic development level, size of research team, network development level, population base and number of urban residents.

  This paper introduces the concept of Named Entity Recognition (NER), analyzes two basic approaches, the rule-based approach and the statistical approach, and conducts an empirical study on Chinese dish name recognition based on the theory of Maximum Entropy Model (MEM). According to the characteristics of Chinese named entity, 6 feature templates are designed. Experimental results show that adding tagging features to the basic simple feature template can efficiently improve the performance of Named Entity Recognition. The features in order to improve recognition performance are as follow: tagging features, combination of POS features, forward POS dependency features and word form features.
