numerous advantages are derived from the electronic health record (ehr).though achieving such advantages depends on its architecture, at present no unique understanding of the architecture dimensions and specifications is available. therefore, the aim of the present study is a systematic review of architecture perception of the electronic health record. the authors searched the literature in sc...
TheWorld WideWeb is now undeniably the richest and most dense source of information, yet its structure makes it diÆcult to make use of that information in a systematic way. This paper extends a pattern discovery approach called IEPAD to the rapid generation of information extractors that can extract structured data from semi-structured Web documents. IEPAD is proposed to automate wrapper genera...
DBpedia is a Semantic Web project aiming to extract structured data from Wikipedia articles. Due to the increasing number of resources linked to it, DBpedia plays a central role in the Linked Open Data community. Currently, the information contained in DBpedia is mainly collected from Wikipedia infoboxes, a set of subject-attribute-value triples that represents a summary of the Wikipedia page. ...
There are various kinds of objects embedded in static Web pages and online Web databases. Extracting and integrating these objects from the Web is of great significance for Web data management. The existing Web information extraction (IE) techniques cannot provide satisfactory solution to the Web object extraction task since objects of the same type are distributed in diverse Web sources, whose...
Web Data Mining is an important area of Data Mining which deals with the extraction of interesting knowledge from the World Wide Web. It defines the application of data mining techniques to extract knowledge from web data, including web documents, hyperlinks between documents, usage logs of web sites, etc. Therefore, the process of extracting useful information from the contents of web document...
The advent of Web 2. 0 has been instrumental in paradigm shift of how people communicate? These communications are a rich source of relationship data. Analyzing such a vast amount of relationship data is not a trivial task. Social Network Analysis is a promising field of research to take advantage of this huge pool of relationship data. But before this data is analyzed from Social Network Analy...
The internet has become an attractive avenue for global e-business, e-learning, knowledge sharing, etc. Due to continuous increase in the volume of web content, it is not practically possible for a user to extract information by browsing and integrating data from a huge amount of web sources retrieved by the existing search engines. The semantic web technology enables advancement in information...
XML, Web services, and the Semantic Web have opened the door for new and exciting information integration applications. Information sources on the web are controlled by different organizations or people, utilize different text formats, and have varying inconsistencies. Therefore, any system that integrates information from different data sources must identify common entities from these sources....
In this work we approach relationships on the Linked Open Data Web as key facilitators of information exploration. Linked Open Data (LOD) principles contribute to a shift in paradigm for information representation and access, enhancing the ability of users and computers to connect, browse and query data on the Web through standard languages and protocols. We present a brief discussion on the cu...
Abstract— Web mining is a class of data mining. In order to relieve a “Data Rich but Information Poor” dilemma, Data Mining emerged. Web Mining is a variation of this field that distils untapped source of abundantly available free textual information. The importance of web mining is growing along with the massive volumes of data generated in web day-to-day life. In general, web data always arri...
