is a connections metric for social networks that measures the ties that actors in a network have with others that are geographically close Answer: Propinquity Diff: 1 Page Ref: 308 60) is a segmentation metric for social networks that measures the strength of the bonds between actors in a social network Answer: Cohesion Diff: 1 Page Ref: 309 61) How would you describe information extraction in text mining Diff: 2 Page Ref: 252 62) Natural language processing(NLP), a subfield of artificial intelligence and computational inguistics, is an important component of text mining. What is the definition of NLP? Answer: NLP is a discipline that studies the problem of"understanding"the natural human language, with the view of converting depictions of human language into more formal representations in the form of numeric and symbolic data that are easier for computer programs to manipulate Diff: 2 Page Ref: 256 63)In the security domain, one of the largest and most prominent text mining applications is the highly classified eChelon surveillance system. What is eChelon assumed to be capable of Answer: Identifying the content of telephone calls, faxes, e-mails, and other types of data and intercepting information sent via satellites, public switched telephone networks, and microwave links Diff: 2 Page Ref: 261-262 64 ) Describe the query-specific clustering method as it relates to clustering Answer: This method employs a hierarchical clustering approach where the most relevant documents to the posed query appear in small tight clusters that are nested in larger clusters containing less similar documents, creating a spectrum of relevance levels among the documents Diff: 3 Page Ref: 272 9 Copyright C 2018 Pearson Education, Inc9 Copyright © 2018 Pearson Education, Inc. 59) ________ is a connections metric for social networks that measures the ties that actors in a network have with others that are geographically close. Answer: Propinquity Diff: 1 Page Ref: 308 60) ________ is a segmentation metric for social networks that measures the strength of the bonds between actors in a social network. Answer: Cohesion Diff: 1 Page Ref: 309 61) How would you describe information extraction in text mining? Answer: Information extraction is the identification of key phrases and relationships within text by looking for predefined objects and sequences in text by way of pattern matching.
