Adaptation and Personalization systems can benefit with the incorporation of ontological knowledge, especially when it comes to modeling users. In this paper we present a cognitive approach to Web Personalization based on an ontology that contains users' cognitive factors. Accordingly, a human factors' ontology has been designed and developed using RDFa, and could be used in any Web-based application...
The use of domain knowledge is generally found to improve query efficiency in content filtering applications. In particular, tangible benefits have been achieved when using knowledge-based approaches within more specialized fields, such as medical free texts or legal documents. However, the problem is that sources of domain knowledge are time consuming to build and equally costly to maintain. As a...
Today, Internet is a huge database which comprises of a large number of Web sites, search engines and other information. Due to the unstructured and semi structured data in the web pages, it is a challenging task for researchers to make a relevant and efficient search in warehouse of such type of database. Ontology may be a good mechanism for achieving this goal and Web Mining technique may be used...
News event modeling and tracking in the social web is the task of discovering which news events individuals in social communities are most interested in, how much discussion these events generate and tracking these discussions over time. The task could provide informative summaries on what has happened in the real world, yield important knowledge on what are the most important events from the crowd's...
Along with the rapid popularity of the Internet, crime information on the web is becoming increasingly rampant, and the majority of them are in the form of text. Because a lot of crime information in documents is described through events, event-based semantic technology can be used to study the patterns and trends of web-oriented crimes. In our research project on cyber crime mining, we construct...
With the pervasion of Internet and the sharp increase of the number of netizens, Network public opinion has been serving as an effective method in the monitoring and reflection of social public opinion. However, Regulatory Authorities are inclined to concern more about public opinion in a special field while it is too difficult to acquisite the expected information that relates to a special area from...
As lack of semantic for information description and semantic support for the query processing, traditional Blog systems are unable to satisfying users in the performance of information organization and retrieval. Through analyzing the existing technologies in Blog systems and focusing on semantic retrieval of Blog information resource, this paper proposes Blog information retrieval model based on...
This paper discusses a modality to access and to organize unstructured contents related to a particular topic coming from the access to Wikipedia pages. The proposed approach is focused on the acquisition of new knowledge from Wikipedia pages and is based on the definition of useful patterns able to extract and identify novel concepts and relations to be added in the knowledge base. We proposes a...
In this paper we present a relation extraction system which uses a combination of pattern based, structure based and statistical approaches. This system uses raw texts and Wikipedia articles to learn conceptual relations. Wikipedia structures are rich source of information in relation extraction and are well used in this system. A set of patterns are extracted for Persian language and are used to...
Remote control over the internet is generating significant research interest, of which a major research challenge is the generation of Web User Interface (WUI) according to individual user's specific requirements, for example different users have an interest in monitoring and controlling different machines. Furthermore, the same user may also be interested in different machines in different sessions...
The following topics are dealt with: distributed scheduling approach; backup sip server system; raid system; fault detection; neighbor-aware dynamic backoff algorithm; ad hoc networks; IP transition phase; data sharing; large scale enterprise; data mining; distributed data warehouses; parallel discrete event simulation; peer-to-peer streaming; OpenMP; service oriented architecture; business process...
Since the Chinese Websites have increased in the explosive Internet era, making efficient information retrieval systems has become one of the major endeavors, especially in fields of Chinese recognition. In this paper, the authors study the integration of subsequence kernel function based on ontology. Using the vector space model (VSM) to create subsequence kernels, the kernel methodology described...
Social networks and fast blogging services are interesting information sources. Anyone can contribute and submit information that matters to him/her. Among these many digital information sources, some appeared on the Internet as public means to be aware and to follow disasters and their evolutions. However, automatic raw information processing is more or less complex, error producer, relevant and...
In order to meet the need of blog users who want to get more interactive information in blog activities and aim at less understanding on the semantic blog interactivity, the paper proposes a four-layer model which is based on the characteristics of semantic blog, and thoroughly describes the interactive process based on the model. The paper divides the retrieval process of semantic blog into the general...
Motivation: Wiki-based databases are becoming popular in biology research, but many of them do not provide a measure to control vocabulary (ontology) of input data despite their use in multi-user environment. We present an extension to MediaWiki, the most popular Wiki-based platform, which realizes implementation of word checks and data integration at the user-level. With this functionality, any user...
Emergent knowledge does not come from a particular document or a particular knowledge source, but comes from a collection of documents or knowledge sources. This paper proposes a system which combines the social Web contents and the semantic Web technology to process the emergent knowledge from the blogosphere. The proposed system regards blog postings as experiences of people on particular topics...
Formulating and executing queries over distributed, autonomous and heterogeneous resources is an important research area. The advent of the Internet and the Web and their inherent ubiquity have brought forth opportunities to query these information sources in an automated and independent manner. In the domain of information extraction, automatic wrapper generation has been well studied but the efficacy...
The types and the ways to organizing network education resources are surveyed. The multilingual thesaurus-ontology is explained. Then it discusses application of multilingual thesaurus-ontology in the organization of network education resources. The purpose of the application is to make network education resources maintain automatically, by the characteristic of self-learning and auto-evolution of...
In this quickly developed and shifting era of Internet, how to make use of webpage indexing structure or search engines which let information demanders fast and precisely search and extract out advantage information has become extremely important capability in users on the Web. This paper combined a data mining tool SPSS Clementine with the domain ontology to mine out usefully important information...
A major component in any Web personalization system is its user model. Recently a number of researches have been done to incorporate semantics of a Web site in representation of its users. All of these efforts use either a specific manually constructed taxonomy or ontology or a general purpose one like WordNet to map page views into semantic elements. However, building a hierarchy of concepts manually...
