Executive Summary

Objective
The hereby report summarizes the results of the extended data mining analysis performed for Nikos Drandakis,
www.sync.gr. The initial data provided regards a survey on bloggers in Greece and their characteristics, which served as the
input for a bunch of advanced methodologies and algorithms run to reveal underlying structure and patterns that reside as
latent across the data. The paragraphs to follow include, among others, a careful selection of the most significant out of
these results, in terms of relevance, consistency and accuracy. The results are presented in a comprehensible and easily
digestible format, ready to support decision making processes.

Goals
The analysis performed served a single goal: To extensively study the given data set in order to search for and find out the
most important of the rules and patterns hidden within the data. The study, eventually, contributes the shaping of these
patterns into usable knowledge, while putting focus on the given variables of specific interest.

Means
The tools and approaches used for extracting the underlying patterns out of the available data set lie in the conjunction of
Artificial Intelligence / Machine Learning and Statistics, an area commonly called Data Mining. The datamine.it team
leverages on extended research experience on the topic to utilize state-of-the-art tools and techniques and provide you with
the most insightful of the results, while yet in an absolutely familiar way.

Outcomes
Among the vast number of results occurred and the most significant out of them to be appeared throughout the report, a
sneak peek of the insights gained is provided here:

    •    The most popular issues covered in the Greek blogosphere are strongly associated with the general characteristics
         of a blogger.
    •    Bloggers customs are determined by their age, their education and their professional occupation.
    •    The use of social web services, such as ‘twitter’, ‘delicious’, ‘facebook’ etc, is related to blogging.

Analysis Report 000-0007                     3
The context

Data, in general
Data stands as the least biased input to decision making, the purest source of insights and knowledge. Today, data is
generated, stored and used at an unprecedented rate and volume. Typical tools available to interpret data generated by
commonly used tools and techniques such as statistical reports and surveys cannot respond efficiently to the hurdles
today's volume of data and required in-depth analysis pose. Datamine.it presents a solution to this problem.

Data Mining, in general
Where classical approaches prove to be ineffective of the scale, speed and simplicity needed, artificial intelligence comes to
join statistics and provide the much needed solution. That solution is Data Mining. You can visualize data mining as a
process of searching for treasure buried in the sand or digging up rock to mine for gold - thus 'mining' -, but the tools we
use do it in a truly systematic and efficient way. In our case, the rock stands for data and the gold are the insights and
knowledge hidden within the data set.

That said, a miner with a mattock in his hand is a very rough way to conceptualize the complexity and state-of-the-art of the
processes executed. A diverse and extended set of exploration and filtering algorithms, next to a variety of learning and
meta-learning techniques, were utilized, optimized and evaluated, while the problem is a computationally intensive one and
demands a highly customized approach.

Data Mine.it, in specific
The paragraphs to follow aim at providing insight on the patterns that emerge from the extended -in both width and depth-
data mining analysis of the given data set. A bunch of sophisticated machine learning algorithms were run and fine-tuned by
one or more datamine.it engineers to end up on extracting outcomes and patterns that make perfect sense for your dataset
and really provide you with insights you never imagined before, or never thought them as being well proven; we like to call it
quot;a tale of discovery, from your data to the report on handquot;. What’s more, rest assured we've worked really hard to separate
the wheat from the chaff, all the peculiar terminology included. And if you were used to concern a pie chart or a histogram as
the most insightful thing you could expect from a data analysis, get ready to be astonished on the pages to follow.

The content

Analysis of the data set
The initial dataset consisted of 31 attributes (you may visualize it as the number of ‘questions performed’, see Appendix I)
and 919 instances (the number of ‘samples collected’). For the sake of our analysis and clarity of the results, we dismantled
these 31 questions into 108 attributes, the analytical description of which is provided in Appendix II, while Table 1 that
follows gives a very sneak peek of them.

                                                  Table 2: Titles of attributes in use




As the target for the analysis served 48 attributes from those listed in Table 2. In other words, the analysis performed
attempt to extract relationships and insights of all other attributes in regard to each one of the 48 attributes at a time. The
distributions of all the attributes are given in the Appendix II.

Due to the sample’s complexity and size, various advanced filtering techniques were repeatedly utilized to firstly rank these
attributes according to their correlation and informational value in regards to the analysis target, and then put focus on the
ones that matter the most.


All attributes are ranked according to their informational value to describe the target attribute. An example of such a ranking
is provided with attribute quot;agequot; serving as the target. Table 4 presents the 10 most valuable out of these, as occurred by
such a process, while Table 5 contributes the ones of least informational value.

Given the rough description of the submitted data set and the analysis framework deployed before, the next paragraph
stands as the core of this report, moving to the actual results of the knowledge discovery process.




Analysis Report 000-0007                                                                                          7
The analysis

Introduction
As referred above, the analysis performed utilized an extended variety of advanced data mining techniques and machine
learning algorithms, next to the outcomes of the data set’s analysis, to finally extract the best and brightest of its latent pat-
terns. Significant effort was also put into transforming these patterns and analysis results into some direct, tangible and easi-
ly comprehensible outcomes.



Best rules discovered
The pages to follow describe in words and figures the most significant out of the rules discovered, in other words the most
distinguishable of the patterns emerged out of the extensive mining processes performed. Each pattern is also described by
the number of cases that validates it across the data set, as well as its success rate. Apart from the rules presented here,
Appendix III provides an extended list of (less or more) significant rules discovered, essentially contributing to the formation
and understanding of the latent knowledge in the given data set.




                Rule 1: If q806_about_news=yes and q811_about_gossip=yes then q808_about_media=yes

General outcomes
The extended analysis performed and the numbers of results presented in the previous pages, as long as in the Appendix III,
clearly shaped out a number of outcomes, the most significant of which are also deployed hereby:

    •    If the blog deals with news and gossip, typically it also refers to media.
    •    If the blogger often uses ‘twitter’ and ‘delicious’ in the social web then he sees about technology subjects in his
         blog.
    •    85% of the respondents who deal with social issues and news in their blogs are also concerned about political top-
         ics.
    •   The social web service ‘google reader’ is preferred by the 75% of the bloggers who don’t often use ‘facebook’ and
         ‘youtube’.
    •    Moreover, bloggers who often use the web service ‘buzz’ prefer the ‘google reader’.
    •    75% of the bloggers who often use ‘twitter’ and ‘linkedln’ use also ‘friendfeed’.
    •    Male respondents who handle social issues in their blogs handle also and political matters.
    •    68% of the blogs which are about music and social issues deal also with art and culture subjects.



While the results found are presented at full extent in the Appendixes below (including the list of the full name and description
of the questions posed and answers submitted, the attributes analytical description and plots, most valuable -information
wise- attributes and a really big list of rules extracted), it is by now clear that the on hand analysis has contributed deep in-
sights, yet simple descriptions, on the patterns and knowledge that were lying unveiled through the submitted data set. This
tale of discovery, from your data to the report on hand, seemed to reach its end, at least on the part of maximizing the value
of your data input. We do believe you’ll come to validate this, while we continuously remain at your request for shaping the
next episode of your data tales.

Analysis Report of Greek Blogosphere by DataMine.it

  • 1. Analysis Report Prepared for: Nikos Drandakis, www.sync.gr Prepared by: Eleutheria Kanavou, Data Engineer, datamine.it January 17th, 2009 Report number: 000-0007 datamine.it 14 Meletiou Vasileiou Str 11 745 Athens, Greece T +30 6937 122 065 go@datamine.it http://datamine.it
  • 2. Executive Summary Objective The hereby report summarizes the results of the extended data mining analysis performed for Nikos Drandakis, www.sync.gr. The initial data provided regards a survey on bloggers in Greece and their characteristics, which served as the input for a bunch of advanced methodologies and algorithms run to reveal underlying structure and patterns that reside as latent across the data. The paragraphs to follow include, among others, a careful selection of the most significant out of these results, in terms of relevance, consistency and accuracy. The results are presented in a comprehensible and easily digestible format, ready to support decision making processes. Goals The analysis performed served a single goal: To extensively study the given data set in order to search for and find out the most important of the rules and patterns hidden within the data. The study, eventually, contributes the shaping of these patterns into usable knowledge, while putting focus on the given variables of specific interest. Means The tools and approaches used for extracting the underlying patterns out of the available data set lie in the conjunction of Artificial Intelligence / Machine Learning and Statistics, an area commonly called Data Mining. The datamine.it team leverages on extended research experience on the topic to utilize state-of-the-art tools and techniques and provide you with the most insightful of the results, while yet in an absolutely familiar way. Outcomes Among the vast number of results occurred and the most significant out of them to be appeared throughout the report, a sneak peek of the insights gained is provided here: • The most popular issues covered in the Greek blogosphere are strongly associated with the general characteristics of a blogger. • Bloggers customs are determined by their age, their education and their professional occupation. • The use of social web services, such as ‘twitter’, ‘delicious’, ‘facebook’ etc, is related to blogging.

  • 4. The context Data, in general Data stands as the least biased input to decision making, the purest source of insights and knowledge. Today, data is generated, stored and used at an unprecedented rate and volume. Typical tools available to interpret data generated by commonly used tools and techniques such as statistical reports and surveys cannot respond efficiently to the hurdles today's volume of data and required in-depth analysis pose. Datamine.it presents a solution to this problem. Data Mining, in general Where classical approaches prove to be ineffective of the scale, speed and simplicity needed, artificial intelligence comes to join statistics and provide the much needed solution. That solution is Data Mining. You can visualize data mining as a process of searching for treasure buried in the sand or digging up rock to mine for gold - thus 'mining' -, but the tools we use do it in a truly systematic and efficient way. In our case, the rock stands for data and the gold are the insights and knowledge hidden within the data set. That said, a miner with a mattock in his hand is a very rough way to conceptualize the complexity and state-of-the-art of the processes executed. A diverse and extended set of exploration and filtering algorithms, next to a variety of learning and meta-learning techniques, were utilized, optimized and evaluated, while the problem is a computationally intensive one and demands a highly customized approach. Data Mine.it, in specific The paragraphs to follow aim at providing insight on the patterns that emerge from the extended -in both width and depth- data mining analysis of the given data set. A bunch of sophisticated machine learning algorithms were run and fine-tuned by one or more datamine.it engineers to end up on extracting outcomes and patterns that make perfect sense for your dataset and really provide you with insights you never imagined before, or never thought them as being well proven; we like to call it quot;a tale of discovery, from your data to the report on handquot;. What’s more, rest assured we've worked really hard to separate the wheat from the chaff, all the peculiar terminology included. And if you were used to concern a pie chart or a histogram as the most insightful thing you could expect from a data analysis, get ready to be astonished on the pages to follow. Analysis Report 000-0007 4
  • 5. The content Analysis of the data set The initial dataset consisted of 31 attributes (you may visualize it as the number of ‘questions performed’, see Appendix I) and 919 instances (the number of ‘samples collected’). For the sake of our analysis and clarity of the results, we dismantled these 31 questions into 108 attributes, the analytical description of which is provided in Appendix II, while Table 1 that follows gives a very sneak peek of them. Description Quantity attributes 108 nominal 108 numeric 0 target 48 instances 919 missing 0 uniques 0 Table 1: Data set at a glance Let's take a deeper view. Table 2 provides the titles of all attributes, which consist the data set. These are referred here to provide you with a broader view of the data in focus that are potentially utilized in the results of the following pages. Again, you may find a more detailed description of the submitted attributes in Appendix II. # Name # Name # Name 1 q101_platform_blogspot 37 q805_about_music 73 q1703_greekprob_humanrights 2 q102_platform_worpress 38 q806_about_news 74 q1704_greekprob_education 3 q103_platform_livespaces 39 q807_about_art_culture 75 q1705_greekprob_insurance 4 q104_platform_pathfinder 40 q808_about_media 76 q1706_greekprob_externalpolicy 5 q105_platform_other 41 q809_about_sport 77 q1707_greekprob_corruption 6 q301_com_forum 42 q810_about_gaming 78 q1708_greekprob_culture 7 q302_com_chatroom 43 q811_about_gossip 79 q1709_greekprob_technology 8 q303_com_socnet 44 q812_about_science 80 q17010_greekprob_healthsys 9 q304_com_other 45 q813_about_religion 81 q18_advert 10 q401_char_blog 46 q814_about_health 82 q19_advert_benef 11 q402_char_blog_other 47 q815_about_other 83 q2001_affect_career_known 12 q501_media_internet 48 q9_anonymity 84 q2002_affect_career_cv 13 q502_media_tv 49 q1001_anonymity_you 85 q2003_affect_career_prestige 14 q503_media_radio 50 q1002_anonymity_you_other 86 q2004_affect_career_changedep 15 q504_media_newspapers 51 q1101_why_blog_opinion 87 q2005_affect_career_leftjob Analysis Report 000-0007 5

In other words, the analysis performed attempt to extract relationships and insights of all other attributes in regard to each one of the 48 attributes at a time. The distributions of all the attributes are given in the Appendix II. Due to the sample’s complexity and size, various advanced filtering techniques were repeatedly utilized to firstly rank these attributes according to their correlation and informational value in regards to the analysis target, and then put focus on the ones that matter the most. All attributes are ranked according to their informational value to describe the target attribute. An example of such a ranking is provided with attribute quot;agequot; serving as the target. Table 4 presents the 10 most valuable out of these, as occurred by such a process, while Table 5 contributes the ones of least informational value. Analysis Report 000-0007 6

  • 8. The analysis Introduction As referred above, the analysis performed utilized an extended variety of advanced data mining techniques and machine learning algorithms, next to the outcomes of the data set’s analysis, to finally extract the best and brightest of its latent pat- terns. Significant effort was also put into transforming these patterns and analysis results into some direct, tangible and easi- ly comprehensible outcomes. Best rules discovered The pages to follow describe in words and figures the most significant out of the rules discovered, in other words the most distinguishable of the patterns emerged out of the extensive mining processes performed. Each pattern is also described by the number of cases that validates it across the data set, as well as its success rate. Apart from the rules presented here, Appendix III provides an extended list of (less or more) significant rules discovered, essentially contributing to the formation and understanding of the latent knowledge in the given data set. Rule 1: If q806_about_news=yes and q811_about_gossip=yes then q808_about_media=yes (39 occurred instances supported this rule, while 7 did not) (85% success) Rule 1 indicates that if the blog deals with news and gossip, then it also includes media topics at a rate of 85%. Analysis Report 000-0007 8
  • 9. Rule 2: If q603_socweb_twitter=yes and q605_socweb_delicious=yes then q804_about_tech=yes (69.0/13.0) (84% success) Rule 2 suggests, with a certainty of 84%, that if the blogger often uses ‘twitter’ and ‘delicious’ in the social web, then he sees about technology subjects in his blog. Rule 3: If q803_about_social=yes and q806_about_news=yes then q802_about_political=yes (247.0/49.0) (83% success) This rule provides the insight that if the respondent deals with social issues and news in his blog, then he is expected to also write about political topics, with an accuracy of 85%. Rule 4: If q27_age=<18 and q502_media_tv=2-3/week then q615_socweb_other=hi5 (4.0/1.0) (80% success) Rule 4 suggests that 80% of the teenagers bloggers, who get informed from television 2-3 times per week, often use the social web service ‘Hi5’. Analysis Report 000-0007 9

Rule 5: If q603_socweb_twitter=yes and q605_socweb_delicious=yes then q608_socweb_flickr=yes (73.0/23.0) (76% success) Rule 5 indicates that if the blogger uses both ‘twitter’ and ‘delicious’, then he also uses ‘flickr’ at a rate 76% between the respondents. Rule 6: If q603_socweb_twitter=yes then q606_socweb_Greader=yes (148.0/47.0) (76% success) Hence, if the blogger uses only the social web service ‘twitter’ then he often uses the service ‘google reader’ with a certainty of 76%. Rule 7: If q612_socweb_myspace=yes and q1001_anonymity_you=nickname then q805_about_music=yes (49.0/16.0) (75% success) Rule 7 indicates that the respondents who often use the web service ‘my space’ and participate in the blog using nicknames deal with music in their blogs. Analysis Report 000-0007 10
  • 11. Rule 8: If q601_socweb_facebook=no and q602_socweb_youtube=no and q615_socweb_other=no then q606_socweb_Google reader=yes (46.0/15.0) (75% success) Rule 8 suggests that ‘google reader’ is also preferred by the 75% of the bloggers who don’t often use ‘facebook’ and ‘you- tube’ or another social web service. Rule 9: If q603_socweb_twitter=yes and q609_socweb_linkedln=yes then q604_socweb_frienfeed=yes (48.0/16.0) (75% success) Another important association between social web services occurs from rule 8. That is, 75% of the bloggers who often use ‘twitter’ and ‘linkedln’ also use ‘friendfeed’. Rule 10: If q27_age=36-45 and q28_annual=no_answer then q601_socweb_facebook=no (46.0/15.0) (75% success) People 36-45 years old with unknown annual income do not often use the social web service ‘facebook’. Analysis Report 000-0007 11
  • 12. Rule 11: If q803_about_social=yes and q31_sex=male then q802_about_political=yes (192.0/69.0) (74% success) Rule 11 suggests that male respondents, who handle social issues in their blogs handle, also write about political subjects. Rule 12: If q1101_why_blog_opinion=definitely and q26_education=tech_inst then q27_age=36-45 (26.0/9.0) (74% success) This rule indicates that graduates of technical educational institutes who use the blogs in order to express their opinion are typically 36-45 years old. Rule 13: If q803_about_social=yes and q401_char_blog=informative then q806_about_news=yes (90.0/34.0) (73% success) Rule 13 suggests that 73% of the bloggers, who deal with social issues and characterize their blogs as informative, also provide news coverage. Analysis Report 000-0007 12
  • 13. Rule 14: If q804_about_tech=yes and q608_socweb_flickr=yes then q1001_anonymity_you=realname (65.0/27.0) (71% success) If a blog concerns technology and its owner is also a flickr user, then he is expected to sign with his real name. Rule 15: If q303_com_socnet=yes and q302_com_chatroom=no then q301_com_forum=no (172.0/69.0) (71% success) 71% of the bloggers who participated in social nets (like ‘facebook’, ‘my space’, etc) before blogging, but not in chat rooms, they neither participated in online forums. Rule 16: If q610_socweb_buzz=yes then q606_socweb_Google reader=yes (47.0/20.0) (70%success) Rule 16 suggests, with a certainty of 70%, that bloggers who often use the web service 'buzz', are also expected to utilize the ‘google reader’ web service. Analysis Report 000-0007 13
  • 14. Rule 17: If q1205_success_users=enough and q804_about_tech=yes then q606_socweb_Google reader=yes (52.0/22.0) (70% success) Among the responders who consider the number of readers as an important success metric and also blog about technolo- gy, 70% of them also use ‘google reader’.

Analysis Report 000-0007 14
  • 15. Rule 19: If q805_about_music=yes and q803_about_social=yes then q807_about_art_culture=yes (103.0/49.0) (68% success) Finally, 68% of the respondents, who write about music and social issues, are expected to also blog on subjects related to culture and the arts. Again, the rules demonstrated here consist a small part of the best rules found, all of which are available in Appendix II. Analysis Report 000-0007 15
  • 16. General outcomes The extended analysis performed and the numbers of results presented in the previous pages, as long as in the Appendix III, clearly shaped out a number of outcomes, the most significant of which are also deployed hereby: • If the blog deals with news and gossip, typically it also refers to media. • If the blogger often uses ‘twitter’ and ‘delicious’ in the social web then he sees about technology subjects in his blog. • 85% of the respondents who deal with social issues and news in their blogs are also concerned about political top- ics. • The social web service ‘google reader’ is preferred by the 75% of the bloggers who don’t often use ‘facebook’ and ‘youtube’. • Moreover, bloggers who often use the web service ‘buzz’ prefer the ‘google reader’. • 75% of the bloggers who often use ‘twitter’ and ‘linkedln’ use also ‘friendfeed’. • Male respondents who handle social issues in their blogs handle also and political matters. • 68% of the blogs which are about music and social issues deal also with art and culture subjects. While the results found are presented at full extent in the Appendixes below (including the list of the full name and description of the questions posed and answers submitted, the attributes analytical description and plots, most valuable -information wise- attributes and a really big list of rules extracted), it is by now clear that the on hand analysis has contributed deep in- sights, yet simple descriptions, on the patterns and knowledge that were lying unveiled through the submitted data set. This tale of discovery, from your data to the report on hand, seemed to reach its end, at least on the part of maximizing the value of your data input. We do believe you’ll come to validate this, while we continuously remain at your request for shaping the next episode of your data tales. Analysis Report 000-0007 16
