Exam 7: Text and Web Mining

Analysis of the information collected by Web servers can help better understand user behavior.Analysis of this data is called ________ analysis.

A ________ is one or more Web pages that provide a collection of links to authoritative pages,reference sites,or a resource list on a specific topic.

Forward-thinking companies like Ask.com,Scholastic,and St.John Health System are actively using Web mining systems to answer important questions of "Who?" "Why?" and "How?" The benefits of integrating these systems:

Text mining is the semi-automated process of extracting ________ from large amounts of unstructured data sources.

The quality of search results is impossible to measure accurately using strictly quantitative measures such as click-through rate,abandonment,and search frequency.Additional quantitative and qualitative measures are required.

The ________ model,which is one where multiple sources of data describing the same population are integrated to increase the depth and richness of the resulting analysis,forms the framework of the Web site optimization ecosystem

Customer experience management applications gather and report direct feedback from site visitors by benchmarking against other sites and offline channels,and by supporting predictive modeling of future visitor behavior.

________ is the grouping of similar documents without having a predefined set of categories.

________ is the process of identifying valid,novel,potentially useful,and ultimately understandable patterns in data stored in structured databases,where the data are organized in records structured by categorical,ordinal,or continuous variables.

Compared to polygraphs for deception-detection,text-based deception detection has the advantages of being nonintrusive and widely applicable to textual data and transcriptions of voice recordings.

Why does the Web pose great challenges for effective and efficient knowledge discovery?

What is the primary purpose of text mining within the context of knowledge discovery?

The benefits of text mining are greatest in areas where very large amounts of textual data are being generated,such as law,academic research,finance,and medicine.

At a very high level,the first of three consecutive tasks in the text mining process is to establish the ________,which is a list of organized documents.

________ is the semi-automated process of extracting patterns from large amounts of unstructured data sources.

Two advantages associated with the implementation of NLP are word sense disambiguation and syntactic ambiguity.

Text mining is important to competitive advantage because knowledge is power,and knowledge is derived from text data sources.

At a very high level,the text mining process consists of each of the following tasks except:

By applying a learning algorithm to parsed text,researchers from Stanford University's NLP lab have developed methods that can automatically identify the concepts and relationships between those concepts in the text.

Text mining can be used to increase cross-selling and up-selling by analyzing the unstructured data generated by call centers.
