Research Gaps Previous groups examined journal papers Journal papers have a lag time of 1 – 2 years Good indicator of long-term trends and historical information
20
Our Focus Conference papers A good indicator of where the field is today A predictor of the near future Larger quantity of papers
21
Data Collection Conference papers are not easy to collect (not in a single database) Some conferences cannot be collected online
22
Data Collection After a search of each database we decided to collect: ICIS, AMCIS, CSCW, HICSS, KDD, SIGIR, WWW Time Frame: 2008-2012
23
Data Collection Data: Title, Abstract, Keywords of total 6,036 papers.
24
Data Collection Different conferences have different website patterns (HTML tags, structures etc.) We programmed text scrapers in Python and PHP for different website patterns
25
Data Collection Data Sources Microsoft Academic Search ACM Proceedings Official Conference Websites
26
Data Collection Source Comparison Microsoft Academic ACM Proceedings Official Websites Data Amount Most conferences missing recent years’ paper Cover all ACM conferences One conference for each site Data QualityDetailed info Missing key words Detailed info Data AccessAPI + Json parsing HTML Crawler + Information Extraction
27
Data Collection Microsoft Academic – JSON Parsing
28
Data Collection ACM Proceedings IE – Regular Expression

What is LDA? Latent Dirichlet Allocation Algorithm used for topic modeling Originates from computer science in 2002 Some open source tools exist to help researchers employ LDA
31
How LDA works Computes chance of certain words appearing together Also looks for word groups that appear exclusive from one another Assumes each document can be a mixture of various topics Returns clusters of words to user and topical make-up of each document
32
An example of LDA Suppose you have the following set of sentences: I like to eat broccoli and bananas. I ate a banana and spinach smoothie for breakfast. Chinchillas and kittens are cute. My sister adopted a kitten yesterday. Look at this cute hamster munching on a piece of broccoli. According to LDA Sentences 1 and 2: 100% Topic A Sentences 3 and 4: 100% Topic B Sentence 5: 60% Topic A, 40% Topic B Topic A: 30% broccoli, 15% bananas, 10% breakfast, 10% munching, … (at which point, you could interpret topic A to be about food) Topic B: 20% chinchillas, 20% kittens, 20% cute, 15% hamster, … (at which point, you could interpret topic B to be about cute animals) Example source: http://blog.echen.me/2011/08/22/introduction-to-latent-dirichlet-allocation/

Conclusion Trending toward technical research Away from behavioral research No more TAM Future work: broaden range of conferences
